### 5/5 — Gut

*2026-02-07*

Macht genau, was sie soll, vor allem das Konvertieren und Umbenennen vieler Bilder auf einmal ist super praktisch. Die Bedienung ist einfach und übersichtlich, iCloud-Profile sind ein echter Vorteil, wenn man Mac und iPad kombiniert. Bei sehr großen Mengen an Biildern braucht es manchmal ein bisschen Geduld, aber insgesamt läuft alles zuverlässig. Sehr nützliche App für den Alltag mit Bildern.

### 5/5 — Top

*2026-02-07*

Funktioniert genau wie beschrieben, vor allem für Stapelverarbeitung echt praktisch. Die Oberfläche ist simpel und die iCloud-Synchronisation nützlich, wenn man mehrere Geräte nutzt. Bei sehr großen Bildmengen merkt man aber manchmal, dass es etwas länger dauert. Insgesamt aber eine solide App, die viele Aufgaben deutlich erleichtert.
