### 5/5 — A clean and simple MP3 tag editor; just what I wanted.

*2026-06-28*

I’ve been looking for a straightforward MP3 tag editor for iPhone, and this is exactly what I wanted. No ads, no subscriptions, no AI trying to guess or “fix” my metadata — just a clean, manual editor that lets me change exactly what I want and nothing else.

The developer was also quick to respond to a question I had, which gave me confidence that the app is actively supported.

If you maintain your own music library and just want a simple, respectful tag editor, I highly recommend TagWeaver.

We truly appreciate your support, and we hope TagWeaver continues to be a valuable part of your music library!
