### 5/5 — Klasse Entscheidungshilfe

*2020-11-21, version 1.2*

Uneingeschränkt weiterzuempfehlen. Super Entscheidungshilfe!!

### 4/5 — Genial, weil es einfach ist

*2020-09-04, version 1.2*

Würde auch einen einmaligen Kauf statt Abo bevorzugen. Ansonsten sehr hilfreich.

### 5/5 — Praktisch und Einzigartig

*2018-10-23, version 1.1*

Eine Außergewöhnliche App, es hilft sehr gut bei nervigen Entscheidungen wo am Gedächtnis sticht. Ein Tod musst man sterben oder wie sagt man?
Natürlich musst man erst mal die App verstehen... aber für ein normales Menschliches Gehirn mit normales IQ ist dies keine Herausforderung :))

### 3/5 — Sehr gute App, leider ein Abomodel

*2018-10-20, version 1.0*

Wäre die App ein einmaliger Kauf ok. Ein Abomodel dafür, ist für mich einfach nicht nachvollziehbar.

### 5/5 — Top App.👌

*2018-08-09, version 1.0*

..sehr hilfreich bei schwierigeren Entscheidungen. Eingabe sehr intuitiv
