### 3/5 — Nice layout but…

*2025-10-30*

I like that you can add pictures and notes, but it keeps deleting days that have been recorded.

**Developer response:** Thank you for your feedback! We're sorry about the issue with recorded days being deleted. We've identified and fixed the bugs causing this in our upcoming v1.0.6 update, which will be released very soon. Please update when it becomes available — your records should then be saved reliably. We appreciate your patience!
