### 1/5 — Dishonest company

*2026-07-20, version 2.2.13*

I just realized I have been paying 12.99 PER WEEK for this app which I don’t use but just happened to open once a couple of months ago.  I apparently “ subscribed” at a cost of over $700 per year.  I am not a novice and I know these apps give you a free trial and then automatically begin billing you.  I am very careful not to subscribe but it seems not careful enough with this ripoff company.  So I went on the app and, guess what, there is no tab to “ manage subscription” or try to cancel.  I have been reduced to emailing them asking how to cancel.  Meanwhile they will attempt to bill me tomorrow for another week.  I don’t know anything about the capabilities of the app but I cannot trust a developer who clearly makes its money  via dishonest and manipulative practices.  Stay away.

### 1/5 — No te dejan quitar el plan de pago luego que pagas

*2026-05-31, version 2.2.12*

No te dejan quitar el plan de pago luego que pagas

### 3/5 — Fotos und Geometriefiguren lassen sich berechnen

*2026-04-12*

Fotos und Geometriefiguren lassen sich berechnen, die auch völlig verschoben sind lassen sich in der Fläche berechnen, hat aber einen Haken der Wochen Preis. 14,99 € pro Woche. Wenn man das Ding nur einmal am Jahr braucht, ist es zu teuer, aber ich habe es für Geometriefiguren benutzt die völlig verschoben sind die kann man in der Fläche berechnen vom Foto aus was bis jetzt bei keiner einzelnen App geht, die ich kenne. Allerdings wie gesagt, der Preis gefällt mir nicht pro Woche. Ansonsten prima App.. ich hab Gott sei Dank eine Ersatzprogramm gefunden. Auf Nimmerwiedersehen. Ich hätte gute Lust, das Ersatzprogramm hier hin zu schreiben, weil die Preisunterschiede gewaltig sind. Ich hatte eigentlich nur ein Programm gesucht und Flächenberechnung vorzunehmen. Auf einem Blatt Papier bei Photomath, zum Beispiel alles andere benutze ich sowieso nicht. Für die anderen Funktionen, die bei diesem Programm noch dabei sind, habe ich genug Ersatz. Es war mir eigentlich nur diese eine Funktion wichtig, alles andere nicht. Nur zur Info.

### 1/5 — 구매취소 환불요청합니다

*2025-11-21*

사진으로 길이측정된다고 받았는데 유료라 편리할줄알고 기대했는데  말도안되게 앱자체가 엉망입니다   에어컨 길이도 엉망으로재고 기능도 몇개없는데 그마저 작동도 안됨  ㅠㅠ 환불해주세요

### 2/5 — Дорого для абонплаты

*2025-05-22*

Дорого для такой программы. Сделайте разовую покупку.

**Developer response:** Thanks for your feedback! We’ll definitely think about adding a one-time purchase option in the future, but for now the app works on a subscription basis.

### 3/5 — Can’t do anything until you put in Credit Card

*2025-02-01, version 2.0.3*

Free Trial of 3 days requires you to put in your credit card first.  Can’t comment on functionality.

### 1/5 — Mal

*2025-01-09, version 2.0.1*

Mala app, no recomiendo
