### 1/5 — App does not do any of the features it claims when paid

*2025-03-23*

I just bought the lifetime paid subscription and none of the features work. Photos and websites do not make you change the way anything is viewed, let you select or save colors.

### 1/5 — Greed, and another bad programmer’s job

*2024-12-31*

False start, Christoph!

**Developer response:** Sorry, seems like we messed up the time slot. Just send me a mail to hello@contrasts.app and we will figure it out :)

### 1/5 — Schrott

*2024-08-10*

Habe es für Farbenblindheit geladen. Das Modul ist nur per In App Kauf verfügbar. Gleich wieder gelöscht da nutzlos

**Developer response:** Hallo Petrapelzer,

vielen Dank für dein Feedback. Es tut mir leid zu hören, dass du enttäuscht bist, dass das Feature nur mit einer Subscription nutzbar ist. Als unabhängiger Entwickler stehe ich vor der Herausforderung, die Entwicklung und den Support der App zu finanzieren. Eine Subscription hilft dabei, die kontinuierliche Verbesserung und den Support der App zu gewährleisten.

Ich verstehe, dass das frustrierend sein kann, aber ich hoffe, dass du dennoch die Qualität und den Nutzen der App insgesamt anerkennst. Vielleicht könntest du deine Bewertung noch einmal überdenken? Falls dir die 7 Tage Testzeit nicht ausreichen, kannst du dich gerne per Mail bei mir melden :)

Vielen Dank, dass du Contrast ausprobiert hast, und für dein Verständnis!


Beste Grüße,  
Christoph

### 1/5 — Schlechte Bedienbarkeit

*2023-10-31*

Ich komme mit dieser App überhaupt nicht klar. Wo/ wie kann ich ein Farbpaar eingeben?
Null Erläuterungen.

**Developer response:** Hallo Kontraste97,

das tut mir wirklich leid zu hören. In der nächsten Version werden wir versuchen, dieses Problem zu lösen.

Zum Anlegen eines Farbpaares müssen sie lediglich das + Icon tappen. Im Folgescreen können sie über den Color Picker (Farbpunkte mit Regenbogenumrandung) Vorder- und Hintergrundgarbe bestimmen. Falls sie das Farbpaar merken wollen, tappen sie auf den Speichern-Button, Probieren sie es aus.

Falls ihnen die App doch gefallen sollte, würden wir uns über eine korrigierte Bewertung freuen.

Viele Grüße!
