SingOn is a free karaoke app that lets you sing along to karaoke videos while your phone works as the microphone. β Karaoke microphone Turn on the mic and your voice comes straight out of the speaker, with echo for that karaoke feel. Pair a Bluetooth speaker and your living room becomes a karaoke room. On the phone speaker, anti-feedback turns on automatically. β Karaoke videos Pick a song and the instrumental (MR) video plays right inside the app - no app switching - and the mic turns on automatically. β Pick a key that fits your voice Choose original, lower or higher key and SingOn finds an instrumental video in that key. Your choice is remembered. β Browse like a songbook Karaoke hits, ballads, 70s & 80s, 90s, sad songs, duets and more. Or search any song and check it with a 30-second preview. β Record yourself Record while you sing and listen back later. Recordings stay on your device and are never uploaded. β Favorites & history Save your go-to songs and find what you sang recently. Search for karaoke places nearby from Settings through your maps app. β No sign-up No account needed. Favorites, recordings and settings stay on this device. The app is free, with an occasional ad after a song. A one-time purchase in Settings removes ads. β Five languages Korean, English, Japanese, Traditional Chinese and Simplified Chinese - song suggestions and categories follow your language. Song info, artwork and 30-second previews come from Apple's iTunes Search API. Karaoke videos play from YouTube.

Verdict
The clearest difference is in-app purchases: SingOn at none against Sound Widgets's 3. SingOn also leads on update cadence (every 3 days vs every 5 weeks) and iOS requirement (15.0 vs 26.0). Sound Widgets's advantage is ads (none vs shown). On price and device support there is nothing between them.
