### 1/5 — This is a scam, don’t waste your money

*2026-02-16*

This app doesn’t work.

**Developer response:** If you have issues with the app you can contact me or ask for a refund. However several users have downloaded it already and I never received this kind of complain.

### 4/5 — Really promising app - hope for more updates!

*2026-01-23*

This is a steal for $2. Transcription is lightning fast and offline. How??? So impressive. Voice quality is far better than Apple onboard. Pronunciation needs work. Even with the custom tool, which has a limited character set for standard IPA, some words ending in S or ED or anything with an apostrophe has problems. That said, if they ever fix up a couple of those things, you’d have a utility that is as useful as a calculator for anybody who uses TTS in their workflow.
