About this app

Lost the tiny remote for your MP3 player? Turn your phone into the remote!

MP3 IR Remote is a simple, fast IR remote control for MP3 players, USB/SD card speakers, MP3 decoder boards, amplifier boards and car MP3 players that come with the small credit-card-style infrared remote. Just point your phone at the device and tap. There's no pairing, no Wi-Fi and no setup.

🚗 Car MP3 means the small 21-key "Car MP3" remote (CH−/CH/CH+, 100+/200+) and the cheap MP3 players, FM transmitters and decoder boards that use it. Branded car stereos (Pioneer, Sony, Kenwood, JVC and others) use their own codes and are not supported.

⚠️ Your phone must have an IR blaster (infrared emitter). This app sends infrared signals just like the original remote, so it can't work over Bluetooth or Wi-Fi. Many Xiaomi, Redmi and POCO phones, and some Huawei, Honor, Vivo and other models, have a built-in IR blaster. Look for a small dark window on the top edge of your phone.

🎛 9 remote layouts Swipe between the most common small IR remotes and pick the one that looks like yours:
• MP3 player remotes: Power, Mode, Mute, Play/Pause, Previous, Next, EQ, Volume −/+, Repeat, U/SD, Clock and number keys 0–9, in several button styles and colors
• Car MP3 remote: CH−/CH/CH+, Previous, Next, Play/Pause, Volume −/+, EQ, 100+/200+ and 0–9
• Arduino starter-kit remotes: the 21-key and 17-key remotes that come with Arduino kits, with a D-pad (▲ ◀ OK ▶ ▼), * and # keys
• Mini remote with D-pad: Volume −/+, Play/Pause, Setup, Stop/Mode, Enter, Return and 0–9

✨ Features
• Works with MP3 players, USB speakers, SD card players, FM/MP3 modules, amplifier boards, car MP3 players and Arduino IR projects using the standard NEC IR remote
• Full keypad: power, play/pause, previous/next track, volume up/down, mute, mode, EQ, repeat, clock and number buttons
• Realistic remote design with large, easy-to-press buttons
• Vibration on key press (can be turned off)
• Optional key-press sounds: choose Click, Tap, Beep, Chirp or Keypad tone
• An on-screen IR light flashes to show when a signal is sent
• Remembers your last-used remote
• Works offline, with no internet needed to send IR signals
• Lightweight and fast, with no account or sign-up
• Nothing to pair or configure: open the app and press a button

📱 How to use
1. Open the app and swipe to the remote that matches your original one.
2. Point the top of your phone at your MP3 player, speaker or board.
3. Tap a button, just like the real remote.

💡 Tips
• Stay within 1–5 meters (3–15 ft) and aim directly at the device's IR receiver.
• If one layout doesn't respond, try another that looks similar; the same-looking remote can send different codes.
• Bright sunlight can interfere with infrared signals.

❓ Why doesn't it work on my phone? The app needs an infrared (IR) blaster. If your phone doesn't have one, it can't send remote signals, and no app can add IR hardware.

🔒 Privacy We don't collect personal data. Your settings stay on your phone. The app is free and supported by ads.

Perfect for replacing a lost or broken MP3 remote, or controlling your music player, speaker, amplifier or car audio from your phone.
