Dodast vs SyncSong

Start a silent disco with the phones already in the room. Dodast is an offline music player and video player for the files on your device, and it syncs playback across phones so everyone hears the same song at the same moment, each on their own headphones or all together as one big speaker. SYNC MUSIC ACROSS PHONES One phone hosts. Guests join over the same Wi-Fi, or over the host's hotspot when there is no network around. They are found automatically under Nearby, or they scan a QR code. From that moment every device plays in step as one. Stack phones into a fuller, louder speaker setup and fill a kitchen, a backyard, a tent or a car. No Bluetooth speaker needed. SILENT DISCO ON YOUR OWN HEADPHONES Everyone on the same song at the same moment, nobody disturbing the neighbors. Each guest listens on their own headphones, sets their own volume and can nudge the sync timing by hand if a device runs a hair ahead or behind. Perfect for a dorm, a hostel, an apartment with thin walls or a party that has to stay silent. WATCH TOGETHER, HEAR IT ON EVERY PHONE Put a video on one screen and let the whole room hear it in sync, each on their own headphones. One device carries the picture, every other phone carries the sound. Made for the moments a speaker would ruin: a show after the house is asleep, a late movie in a shared room, anywhere everyone wants their own volume. A REAL OFFLINE MUSIC PLAYER Dodast is a local music player you would use every day, sync or not. It scans the MP3, FLAC, WAV, M4A and other audio and video files already on your iPhone, reads tags and album art, then stays out of your way. • Browse by songs, albums, artists and folders • Build playlists and reorder them freely • Fast search across your whole library • Crossfade between songs • Sleep timer for the end of the night • Background playback and lock screen controls • Home Screen and Lock Screen widgets • 20 languages • Works with no internet connection at all THE MUSIC ALREADY ON YOUR IPHONE Dodast plays the music library already on your iPhone: the songs you bought and downloaded, tracks you imported from your Mac or PC, files saved in the Files app, and anything shared to Dodast from another app. Years of collecting, finally playing on every phone in the room at once. No more passing one earbud back and forth. Music from a streaming subscription stays protected by its provider and cannot be played by any third-party app. NO ACCOUNT, NO CLOUD Nothing is uploaded to a server. The phones connect directly to each other on your local network. No account, no sign-up. WHAT YOU NEED • Dodast installed on each iPhone or iPad • A shared Wi-Fi network, or one device acting as a hotspot • Your own music and video files Great for road trips, house parties, picnics, dorm rooms, hotel rooms, camping, study sessions and late night movie nights. Any moment worth hearing together. Line up the phones. Press play together. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

SyncSong plays the same music, at the same moment, on several phones at once. One phone is the host: it holds the music and controls playback. Every other phone joins as a client, receives the songs it does not already have, and follows the host's playhead in real time. Press play once and the whole room hears it together. NO NETWORK REQUIRED Phones find each other over Bluetooth LE, so SyncSong works on a walk, in a park, in a car — anywhere, with no shared Wi-Fi and no internet connection at all. On a network you know, switch to Wi-Fi instead for much faster song transfers. The choice is a single tap on the home screen and it is remembered. NOTHING TO SIGN UP FOR There is no account, no subscription and no cloud service. Your music never leaves the phones taking part. Hosts are discovered automatically on the same network; if discovery is blocked, a host's address can be typed in by hand. STAYS IN STEP The client measures the round trip to the host rather than trusting the two clocks to agree, so playback stays aligned even when the phones' clocks differ. Drift is corrected continuously, and a per-host offset control lets you nudge the timing by hand if one phone's speaker or headphones run behind. BRING YOUR OWN MUSIC Add songs from your music library, from Files and Downloads, or from a direct link to an audio file. The host's library is shared with everyone who joins. WHAT IT IS NOT SyncSong is not a streaming service and has no catalogue of its own. It plays audio files you already have. It cannot play music from a streaming subscription, and it cannot export DRM-protected tracks from your library. Up to four phones can follow one host at a time.
