### 4/5 — Okay

*2024-05-22, version 1.1*

Eine schöne Spielerei, aber leider erreicht die App sehr schnell ihr Zoom-Limit, sodass man an die tiefer versteckten Schönheiten gar nicht herankommt.

### 4/5 — Doesn’t let you zoom very far

*2024-02-16*

This app does not let you zoom very deep in to the Mandlebrot before it becomes pixilated.

### 5/5 — So schön kann Mathematik sein!

*2019-10-28, version 1.0*

Wow, danke, das erinnert mich an mein erstes Mandelbrotprogramm auf dem Commodore 64 in BASIC mit Rechenzeiten von 8 bis 10 Stunden...
