A Comprehensive Guide to Apps You Can Use on the Delphin

A Comprehensive Guide to Apps You Can Use on the Delphin

This article is an ongoing project and will be updated periodically as new apps are released and old apps are updated.

We've compiled a guide to the best apps that you can download for the Delphin. Have any to add? Let us know in the comments down below!



Amazon Appstore

This is the most important app to download on to the Delphin. The Amazon Appstore is needed to download any apps on to the Delphin! If you need help downloading this app, click on this link or give our amazing Customer Service department a call at 877-849-0750 or email at help@underwateraudio.com.


Lap Tracking

The Lap Tracking app is designed in-house by our engineers and allows you to track your lap counts, time and calories burned. When used in conjunction with one of our waterproof headphones, you will be able to hear your workout details in real time! This app also allows you to create customized swimming workouts, which is useful if you don’t know what to work on next. If you download the companion app on your phone, you will be able to view your workout information and review it. The Lap Tracking app is (in our opinion) every swimmer’s dream!

Music Players

Pi Music Player

Pi Music Player is an alternative to the Music app on the Delphin; it’s an application that plays MP3s and other audio files that you have stored on your Delphin. It features an equalizer with multiple presets, and a layout that’s easy to navigate even on a Delphin screen. You can also easily share your music with friends from the app. It’s completely free, and it has a very high reviewer rating.


Black Music Player
This is another alternative app to the Music app that is included on the Delphin. It features a minimalist aesthetic, lots of customizability, and like the Pi, an equalizer. It's also totally free.



Streaming Music Apps

Do you want access to millions of artist and albums? With Spotify, you can access tons of today’s most popular artist right on your Delphin. You can even curate your own playlists and download them for offline listening. The app itself is free, but the free version does not allow you to select individual songs you want to listen to and your playlists are always on a shuffle. If you upgrade to the Spotify Premium, which is $9.99 a month, you can listen to music without annoying ads and you have more control in regards to what music you want to listen to.

The Spotify app on the Delphin is a game changer! If you have a strong wifi connection on your Delphin, you may stream your music while you swim. We have had reports where one of our employees streamed her Spotify playlist via a community pool’s Wi-Fi. However, if you don’t have any Wi -Fi, we suggest downloading your playlist beforehand, so you can listen to them offline.

Price: Free, $4.99 for Student Premium, $9.99/mo for Premium, $14.99/mo for Family



Pandora is one of the oldest Internet radio apps in the game, and it has a devoted base of 75 million users, which is the largest of any music streaming app. There are three tiers of use on Pandora. Standard Pandora use is free, but limits you to listening to radio stations based on artists, songs, albums, or genres; no specific song-searching here, no offline-listening, and you can’t skip ads. For offline-listening and ad-free rotation, you’ll need to upgrade to the Plus tier, and to listen to any song on demand you’ll need to upgrade to the Premium tier.

Price: Free, $4.99/mo for Plus, $9.99/mo for Premium, $14.99/mo for Family


Amazon Music

Amazon’s existence in the music streaming world is definitely a layered one. If you’re someone who just wants to listen to music that you’ve already purchased through Amazon, you can do that in this app for free. If you’re already an Amazon Prime member, you can stream from a limited catalogue of music (around 2 million songs), and download and listen to those tracks offline. But, if you want more, you’ll need to purchase an Amazon Music Unlimited subscription, which will give you full access to the Amazon Music catalogue (around 25 million songs), curated playlists, and the like. Downside: Amazon’s music streaming service is only available in the U.S., Canada, Japan, India, half of Europe, and a handful of other places, so if you live somewhere else, you might be better off trying something like Spotify or Deezer.

Price: $9.99/mo for Unlimited, limited use included with $6.49/mo Prime for Students or $12.99/mo Prime



iHeartRadio is where most people go when they want to use their mobile devices to listen to AM or FM radio stations, or to create their own custom stations based on certain songs, but there’s much more to iHR than just that. iHeartRadio Plus allows you to skip any number of songs, and save and replay songs from the radio. But, if you want offline listening for lap swimming, you’ll need to upgrade to iHeartRadio All Access.

Price: Free, $4.99/mo for Plus, $9.99/mo for All Access



Want a music streaming app that delivers insane audio quality? Tidal is where you should start looking. There are two price tiers for this app: $10/month for 320kbps AAC files, or $20/month for Lossless FLAC files that deliver supreme high-fidelity. There are also curated playlists, an offline mode, and exclusive access to music by artists such as JAY Z and Beyonce. However, the price tag is a bit of a deterrent for some.

Price: $9.99/mo for CD quality, $19.99/mo for Lossless quality



Deezer is the music app developed in Paris that is currently available in a whopping 180 countries. So, odds are, it’s available where you are. There are also more songs available on Deezer than there are on Apple Music, Spotify or Tidal. There are two tiers of a paid subscription: $10/month for Premium and $15/month for Lossless-quality Elite, but Elite is not available everywhere, so do your research before you put down the extra cash.

Price: $9.99/mo for Premium, $14.99/mo for Elite


Podcast Addict

Podcast Addict gets our vote when it comes to podcast apps.  It features a full database and search engine, and can also pull podcasts from iTunes' database to make sure you get the widest selection around.  It also has automatic updates, playlist support, and variable speed, and it even lets you customize how large the skips are when you press the Delphin's forward/back controls.  The free version has a (mostly unobtrusive) ad banner at the bottom of the screen, but if it bothers you, the ad-free version is only $2.99. 

Everything else

There are a huge number of podcast apps available on Android, including Podcast Republic, Doggcatcher, and Stitcher, just to name a few.  Podcast apps basically all do the same thing and most of the important features are standardized now, so we recommend sticking to Podcast Addict as that's the one we've tested most thoroughly (although we can also confirm that Stitcher works).  If you have your heart set on a particular app, send us an email and we can test it for you.


For a long time, our customers asked for a device that could play Audible audiobooks in their proprietary format. Most MP3 players couldn’t do it, so us audiobook lovers were stuck. No longer! The famous audiobook app, owned by adoptive parent company Amazon, is available on Delphin, and it works super well. It requires a subscription, but that subscription includes one immediate free download, the ability to borrow books, and access to thousands of titles in the public domain, among many other things. Just make sure to download your files so that you can use them offline while you swim.



Axis 360

Hundreds of local and school libraries have connected to Axis360 in order to loan out their resources online. And that includes audiobooks. Just type in a code from a compatible library card and you’re in! Listen to books from your local library right on your Delphin.


Other Apps


Zello, in its simplest sense, is a walkie-talkie app that is typically used between two phones to communicate using Wi-Fi instead of cellular service. It’s proven useful for any reason one might want to communicate with a walkie-talkie, including communicating during natural disasters, but we at Underwater Audio realized that downloading this app might allow someone at the side of the pool to speak to a swimmer with a Delphin, so we tested it, and it works beautifully. A coach can use this app on his or her phone to give directions to a swimmer or even to a group of swimmers simultaneously - as long as each swimmer has a Delphin!



Ever tried swimming in sync with music? It’s pretty difficult. Now have you ever tried swimming in sync with music, at the exact time as other people swimming in sync with the same music? It’s pretty much impossible. Luckily, AmpMe on Delphin is here to help. Use AmpMe to start listening to a song from Spotify, SoundCloud, Deezer, or your personal library, and allow other Delphin users with AmpMe to join your party. Each member of the party will hear the same track at the exact same point. Suddenly, training to swim in sync is possible! You can even include a Bluetooth speaker in the party, so those outside of the pool can hear, too.
