Minimal Sing-Through

Build your confidence before playing on the street.

Minimal Sing-Through helps you check a song from start to finish. Sing it through once, and the app shows where your voice broke off, for example where a line went blank, and which held notes went flat, sharp or unsteady. Nothing else: no lyrics, no score, no one rating you.

🎤 How to use
1. Tap the microphone and sing. If you sing with a backing track, wear headphones so the microphone hears only your voice.
2. Tap stop. The result appears straight away.
3. Tap a mark on the timeline or in the list to hear the moment, starting 3 seconds before.
4. Record more takes. The best one is marked ★.
5. Save the take you want to keep, trimmed to the singing.

What you can do
- Find breaks: silences inside the song that are much longer than your usual breaths
- Find held notes that are flat, sharp or unsteady. Pitch is judged against your own tuning, so a song sung in a different key or tuning is not penalised, and vibrato is not counted as unsteady
- With two or more takes, a silence found in the same place in most takes, such as an instrumental break, is treated as part of the song and not counted
- Pick the best take automatically: fewest breaks, then fewest pitch marks
- Strictness: Easy, Normal or Strict
- Add videos from your gallery as takes, and save a trimmed copy
- Save a recorded take as an M4A audio file, without the silence before and after

What it does not do
- It does not provide songs, lyrics, backing tracks or reference melodies
- It does not give a score and does not compare you with the original singer
- It is not a voice lesson and does not assess vocal health
- Sound from a speaker reaching the microphone can make the results less accurate. Use headphones for backing tracks
- Very high notes (above about 1,100 Hz) are not analysed
- Takes are kept only while the app is open. Save the ones you want to keep
- Recording stops when you leave the app. It does not record in the background

🔒 Offline and private
The app works without an internet connection and does not request internet access. The only permission is the microphone, used while you record a take. Audio stays on your phone and is never uploaded. There is no account, and no analytics, ads or tracking.

Design
Portrait layout with light and dark themes. The screens use icons and numbers instead of text where possible.

Support
All features are available without payment. If you would like to support development, there are three optional in-app items (Coffee, Lunch and Dinner-sized Support). They do not unlock anything.
