Do you want to boost your voice in the public, or love to sing karaoke? If you have a portable bluetooth speaker, this app is a must for your iPhone / iPad. Bluetooth Loudspeaker is an app to amplify your voice output to your wireless connected bluetooth speaker. That is, your iPhone becomes the microphone and the bluetooth speaker becomes a remote loudspeaker within 10 meters distance. As this app can run at background, your iPhone can play mp3 music and let you sing karaoke at the same time. What can you do with a microphone and remote loudspeaker? Who needs this mic and remote loudspeaker? Some examples are: - sing karaoke at home or anywhere, - teaching in a classroom or lecture room, - street performance, live show, - speaker in a large conference room, - garage sale, outdoor sale, pop-up store sale, or other sales promotion, - tour guide at the hot spot, - fan of a sport team, who sing loud to support the favourite sport team in the stadium, - outdoor activities, - works as volume booster or megaphone for your speech, - beach party, birthday party, exhibitions, celebrations and many more cases. With this app, you have a wireless microphone on your hand! Read me first: 1. User must connect to a bluetooth speaker when using this app for voice output. Do NOT choose device internal speaker, as there will be some unwanted echo noise. 2. This app will NOT bluetooth or airplay connect to your remote speaker. User has to manually connect to the speaker first (through Settings > Bluetooth). Then open this app. 3. When using this app to output voice to connected bluetooth speaker, user can put this app as background job and run another music app such as Apple Music (or any music app). To stop, go back to this app and tap the stop button. 4. This app does NOT support wired headset / headphone or bluetooth headset or line-out. 5. This app does not download or play online mp3 music or video. 6. Remember to turn device output volume to about 80-90% maximum (at top right icon), and mic gain to about 40-50% (at bottom slide bar). 7. Some iPad mic is located on top of the device, while most iPhone default mic is at the bottom. From iOS 14 and on, there will be an ads tracking dialog popup once, which is required for new iOS user privacy purpose. We do not collect any data from user or device.

Verdict
The clearest difference is review sentiment: Bluetooth Loudspeaker at 78% against Sound Amplifier's 34%. Sound Amplifier's advantage is ads (none vs shown) and update cadence (every 2 weeks vs every 2 months). On price, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Bluetooth Loudspeaker sells 2 one-off in-app purchases and Sound Amplifier sells 4 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
Sound Amplifier holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Sound Amplifier has 1.2K ratings behind it against 26, so its average is the more settled of the two. Written reviews complicate that: 78% of Bluetooth Loudspeaker's written reviews are positive against 34% of Sound Amplifier's, so the app with the better star average is not the one people write more warmly about.
Bluetooth Loudspeaker ships an update every 2 months, Sound Amplifier every 2 weeks. The most recent releases landed on October 22, 2026 and October 21, 2026 respectively.
