### 5/5 — Convert Freely, Keep It Private

*2026-04-27*

Formattery is nice file converter, especially for quickly handling different formats without relying on online tools. One feature I’d really love to see is a Mac menu bar mode, because it would make opening the app and converting files much faster and more convenient in daily use.

**Developer response:** Thank you so much for your review, I’ll try to add it soon!

### 5/5 — Finally, a private file converter!

*2026-04-10*

This app is incredibly useful! I love that everything converts 100% on-device, so my files stay private with no uploads. It handles 80+ formats including images, documents, video, and even ebooks & 3D models. The batch conversion and quality adjustment are lifesavers. Best of all: no subscription, just a one-time Pro upgrade. Highly recommend!

**Developer response:** Thank you so much for your review, we’ll keep improving for you

### 3/5 — استفسار

*2026-03-13*

لماذا لا يمكن شراء نسخة البرو (pro)

**Developer response:** صباح الخير، لقد رصدنا مشكلة في ملف تعريف الدفع، وقد تم حلها بالتحديث الجديد. يمكنك الآن تفعيل النسخة الاحترافية. مع أطيب التحيات.
