Your listeners are not sitting at a desktop computer opening a browser to find your station.
They are on their phone. On their commute. At the gym. In the kitchen while cooking dinner. In the car during a school run. In every one of these situations, they are using an app to access the audio content that accompanies their day.
Understanding which apps your listeners are using is not a passive interest for a growing radio station. It is operational intelligence. Every app your station is present on is a discovery channel that delivers new listeners indefinitely at zero ongoing cost. Every app your station is absent from is a discovery channel delivering listeners to your competitors instead.
This guide covers every major internet radio app that matters for listeners in 2026, what each one does, how large their active user base is, what kind of stations perform best on each platform, and exactly what your station needs to do to be present, visible, and well-represented on every one of them.
Why the App Landscape Matters More Than Any Other Distribution Decision
Digital audio consumption shifted irreversibly to mobile over the last five years. Over 70 percent of all internet radio listening now happens on a smartphone or tablet. The listener who discovered internet radio through a desktop browser in 2015 is the same listener accessing their favourite stations through a dedicated app on their iPhone or Android device in 2026.
This shift has practical consequences for every radio station’s growth strategy. A station that is live on a solid hosting platform with great content but is absent from the major listener apps is invisible to the majority of its potential audience. The potential listener browsing TuneIn on their morning commute will never find a station that is not listed on TuneIn. The listener using Radio Garden to explore global radio will never encounter a station that has not submitted to Radio Garden.
App presence is not a technical afterthought. It is where your audience lives and where they are actively looking for what you broadcast.
For broadcasters, understanding the app landscape also informs infrastructure decisions. A station expecting significant traffic from TuneIn’s 75 million monthly active users needs unlimited radio hosting that handles listener spikes without connection caps. A station featured on TTT Radio Network’s own mobile app needs station automation running 24 hours a day so app listeners who open the app at any hour find an active broadcast. The app landscape and the hosting infrastructure decisions are directly connected.
TuneIn Radio: The Largest Internet Radio App in the World
Available on: iOS, Android, Amazon Echo, Apple CarPlay, Android Auto, smart TVs, Xbox, PlayStation
Monthly active users: 75 million plus
Best for: All genres, all formats, global discovery
TuneIn Radio is the undisputed dominant platform in internet radio app distribution. With over 75 million monthly active listeners and integrations across every major device category from smartphones through smart speakers to in-car entertainment systems, TuneIn is the single highest-priority app presence for any internet radio station.
TuneIn’s listener base skews toward active radio listeners who know what genre they want and use TuneIn’s search and browse functionality to find stations in that category. A well-submitted station with an accurate genre tag, a compelling description, and a high-quality logo appears in TuneIn’s genre search results for every listener actively looking for that format.
The Amazon Alexa integration is particularly valuable for stations targeting home listeners. When a listener says “Alexa, play gospel radio” or “Alexa, find a jazz station”, TuneIn’s database is what Alexa searches. Being present on TuneIn with accurate genre tags makes your station voice-searchable on hundreds of millions of smart speakers worldwide. That passive discovery infrastructure delivers new listeners without any ongoing effort from your station.
Apple CarPlay and Android Auto integration means TuneIn-listed stations are accessible to in-car listeners, one of the highest time-spent listening contexts available. A commuter who discovers your station through TuneIn’s CarPlay interface and listens for 45 minutes during their commute is experiencing your station in the most concentrated, attentive listening environment that exists outside of dedicated home audio setups.
To submit your station to TuneIn, visit tunein.com/broadcasters and complete the broadcaster submission form with your stream URL, station name, genre, language, and logo artwork. Approval typically takes between 24 hours and two weeks.
Radio Garden: The Discovery App That Reaches Genuinely Global Audiences
Available on: iOS, Android, web browser
Monthly active users: 15 million plus
Best for: Stations with a geographic identity, cultural and diaspora broadcasting, world music formats
Radio Garden presents internet radio stations as dots on an interactive 3D globe. Listeners spin the globe, zoom into a region, and tap a dot to start listening to a station from that location. The interface is visually distinctive and creates a browsing experience that feels fundamentally different from list-based directory apps.
Radio Garden’s unique mechanic drives a specific type of listener discovery that no other platform replicates. A listener curious about radio from Nigeria, Jamaica, the UK Caribbean community, or any other geographic and cultural identity navigates directly to that region and browses available stations. For stations with a strong geographic or cultural identity, Radio Garden delivers listeners who are specifically seeking that identity rather than generally browsing a genre.
The diaspora broadcasting opportunity on Radio Garden is significant and underused by many culturally-specific stations. A Caribbean station serving the UK diaspora community has a passionate potential audience in Radio Garden’s user base who are actively using the app to find audio content connected to their cultural roots. Being present, correctly located, and well-described on Radio Garden is a direct line to that audience.
Submit your station to Radio Garden through their website submission process at radio.garden. You will need to specify your station’s geographic location accurately because the globe interface places your station’s dot at the coordinates you provide.
RadioBrowser: The Open Source Database That Powers Dozens of Apps Simultaneously
Available on: Multiple third-party apps on iOS, Android, desktop, smart TV, and in-car
Monthly active users: Distributed across many apps, collectively tens of millions
Best for: All genres, technical users, in-car and smart device listeners
RadioBrowser is not a consumer app itself but rather an open source, community-maintained database of internet radio stations that powers dozens of third-party radio apps simultaneously. Apps including Radionomy, GRadio, Transistor, and many others on Android Auto and Apple CarPlay draw their station listings from RadioBrowser’s database.
The multiplication effect of a RadioBrowser listing is its primary value. One submission to RadioBrowser’s database appears across every app that uses RadioBrowser as its station source simultaneously. A station listed on RadioBrowser is accessible from a large ecosystem of apps without separate submission to each one. For a broadcaster investing time in directory submissions, RadioBrowser delivers the highest ratio of app presence to submission effort of any directory available.
Submit your station at www.radio-browser.info through their station addition form. The community-maintained nature of the database means submissions are reviewed by volunteer moderators. Providing accurate genre tags, a clear description, and a reliable stream URL that has been tested before submission improves both approval speed and your station’s search relevance within the database.
Online Radio Box: The Directory With Deep Genre Communities
Available on: iOS, Android, web browser
Monthly active users: 5 million plus
Best for: Niche genre stations, stations with strong listener review potential
Online Radio Box combines directory listing with a listener review and rating system that gives stations social proof within the app. Listeners can rate stations, leave reviews, and mark stations as favourites. Stations with positive reviews and high ratings rank higher in category search results within the app, creating a compounding visibility advantage for stations with engaged, loyal listeners.
For niche genre stations, Online Radio Box’s deep genre categorisation system is particularly valuable. Categories go well beyond broad genre labels into sub-genres and format categories that allow a very specific station, a Northern Soul station, a 90s R&B station, a roots reggae station, to appear prominently in searches for that specific format rather than competing against hundreds of general stations in a top-level genre category.
Encouraging your existing listeners to rate and review your station on Online Radio Box is one of the most cost-effective promotional actions available for improving your visibility within the app. A station with 20 positive reviews ranks significantly higher in category searches than an equivalent station with zero reviews, regardless of technical listening statistics.
Submit at onlineradiobox.com through their broadcaster submission form with your stream URL, genre tags, and station information.
Streema: The Directory That Indexes Beyond What Others Cover
Available on: Web browser, iOS, Android
Monthly active users: 3 million plus
Best for: All genres, stations seeking maximum directory coverage
Streema is a comprehensive internet radio directory that covers a broad range of stations including many smaller and more niche stations that larger directories may not actively curate. For broadcasters pursuing maximum directory coverage, Streema submission ensures your station is findable by the listener base that uses Streema’s search rather than TuneIn or RadioBrowser.
Streema’s listener base includes a significant proportion of listeners in regions where TuneIn’s penetration is lower, making it a valuable complement to TuneIn submission for stations with international audiences or stations targeting specific regional markets where TuneIn is not the dominant app.
TTT Radio Network App: Your Most Valuable App Presence as a Hosted Broadcaster
Available on: iOS, Android
User base: Active internet radio listeners on the TTT Radio Network platform
Best for: All hosted TTT Radio Network station broadcasters on Basic, Premium, and Exclusive plans
The TTT Radio Network mobile app is distinct from third-party directory apps in a way that matters fundamentally for your station’s mobile presence. Third-party directory apps list your station among thousands of others and leave discovery entirely to search and browse mechanics. The TTT Radio Network app features your station in a dedicated broadcasting environment where app users are actively browsing for stations to follow within the platform.
The app includes live chat between presenters and listeners during broadcasts, which is the feature that creates the interactive community experience that no third-party directory app provides. A listener who discovers your station through TuneIn and enjoys what they hear has a passive listening experience. A listener who discovers your station through the TTT Radio Network app, tunes in during a live show, and sends a message that your DJ acknowledges on air has an active community experience. The difference in loyalty and retention between those two listener types is significant and measurable.
Live stream recording integration means your recorded shows are accessible through your station profile on the app, giving new listeners who arrive between live shows content to explore before your next broadcast. This on-demand archive functionality is not available through external directory apps.
For broadcasters on Basic, Premium, and Exclusive plans, your station is featured on the TTT Radio Network app as part of your hosting plan with no additional submission or configuration required. Your station appears in the app from the day your account is activated.
MyTuner Radio: The Emerging App Gaining European and Global Traction
Available on: iOS, Android, web browser
Monthly active users: 10 million plus
Best for: Stations targeting European audiences, global genre broadcasters
MyTuner Radio is a growing internet radio app with particularly strong user penetration in European markets and a well-designed genre browse interface that surfaces niche stations more effectively than some larger competitors. For stations targeting European listener demographics or broadcasting formats popular in European markets, MyTuner submission is worth prioritising.
MyTuner’s interface design presents stations with a card-based layout that gives each station’s logo prominent visual space, making professional station branding more impactful in MyTuner’s browse experience than in text-heavy directory interfaces. Investing in a high-quality station logo pays visible dividends in MyTuner specifically.
Submit at mytuner-radio.com through their radio station submission process.
iHeartRadio: The Platform for Stations Targeting American Audiences
Available on: iOS, Android, web browser, smart speakers, in-car
Monthly active users: 120 million plus (including music and podcast content)
Best for: US-focused stations, particularly urban, country, and talk formats
iHeartRadio is primarily known as an on-demand music and podcast platform but maintains an internet radio directory section that reaches a substantial American listener base. For stations targeting US audiences specifically, particularly urban music stations, gospel stations, country formats, and talk radio, iHeartRadio directory listing connects your station to a large US-centric listener base that uses iHeartRadio as their primary audio app.
iHeartRadio’s smart speaker integrations and in-car audio system partnerships make it particularly valuable for US-focused stations targeting home and in-car listeners.
How to Optimise Your Station Profile Across Every App
Being listed on these apps is step one. Being discoverable and compelling within each app is where the real work lies. The same principles apply across every platform.
Your station logo is the first thing a browsing listener sees. It needs to be sharp, readable, and professional at small dimensions, specifically at 200 by 200 pixels or smaller since most apps display logos at thumbnail size. A simple, bold design with one or two colours reads better at thumbnail size than a complex design that loses detail when scaled down.
Your station description should speak directly to your target listener in their language rather than describing your station in broadcasting industry terms. “The UK’s home for 90s R&B, playing the tracks that defined a generation every hour of every day” is a description that speaks to the listener. “An internet radio station broadcasting R&B content” is a description that speaks to nobody.
Your genre tags should be as specific as the platform allows. Broad genre tags like “music” or “urban” place you in categories with thousands of competing stations. Specific tags like “90s R&B”, “UK gospel”, “afrobeats”, or “roots reggae” place you in categories with fewer stations and more targeted listeners who are specifically seeking your format.
Your stream URL must be the most reliable, permanent URL available from your internet radio hosting provider. Directory listings with dead or changed stream URLs accumulate broken listener experiences over time and rank lower in directory algorithms that monitor stream reliability. When you set up your directory listings, use your primary stream URL and keep it stable.
The Full App Submission Checklist for Maximum Discovery
Work through this checklist in one dedicated session. Each submission takes 10 to 20 minutes. The total investment of two to three hours creates passive discovery infrastructure that delivers new listeners permanently.
TuneIn Radio at tunein.com/broadcasters. Radio Garden at radio.garden. RadioBrowser at www.radio-browser.info. Online Radio Box at onlineradiobox.com. Streema at streema.com. MyTuner Radio at mytuner-radio.com. iHeartRadio broadcaster submission for US-focused stations. TTT Radio Network app featuring through your hosting control panel for hosted broadcasters.
After submission, search for your station on each platform to confirm your listing is live and displaying correctly. Check that your logo appears at good quality, your genre tags are correct, and your stream plays without issues when accessed through each app’s built-in player.
The broadcasters who take this checklist seriously and complete every submission in their first week generate measurably more organic listener growth than those who submit to one or two directories and consider the task done. Directory presence compounds over time as each platform’s algorithm associates your station with consistent streaming and listener engagement. Start early and start comprehensively.
Your listeners are on these apps right now searching for something worth listening to. Visit tttradionetwork.com to ensure your hosting infrastructure supports the audience that full app presence will bring, or contact the team at info@tttradionetwork.com and 860-704-9848.
