### 3/5 — hello

*2024-01-20, version 2.1*

Useful but should not have the review because it is not a game

### 3/5 — Calculo temperatura

*2023-12-23, version 2.0.4*

No puedes poner valores negativos para el cálculo, por ejemplo de -22° F a OCHO

### 2/5 — Worthless

*2023-05-31*

You can’t use the calculator for all the adds that pop up before you finish the equation

### 3/5 — Odd UX

*2022-10-19*

Just odd choices in the design, e.g edit area is small and faint and result is displayed separately. It gets confused by its own decimal places when continuing a calculation. Shows Some promise, but needs better testing if it’s still unusable at v 1.2

### 3/5 — No puedo agregar divisas

*2022-08-08, version 1.2*

La calculadora es simple y tiene iconos que ayudan a cambiar entre los distintos modos rápidamente, pero solo tiene un listado limitado de divisas y no se pueden agregar

### 3/5 — Ok but …

*2022-04-24*

Needs a clear history bottom or a way to delete certain equations.

### 2/5 — Mittelmäßig, mehr nicht

*2022-01-02*

Kein Deutsch, bei der Währung zu wenig Auswahl, fehlt Nuevo Sol / Peru. Woher werden die Devisendaten bezogen?
Last but not least, Abo.  Für einen simplen Taschenrechner? Nein danke 😆

### 4/5 — Einwandfrei

*2021-12-04*

### 1/5 — 👎🏻

*2026-01-14*

𝗸𝗲𝗶𝗻 𝗔𝗽𝗼𝘀𝘁𝗿𝗼𝗳 & 𝗯𝗹𝗼̈𝗱

### 1/5 — Werbung nach =

*2024-01-02*

Da gibt man ne Rechnung ein, drückt auf = und dann kommt erst mal Werbung statt dem Ergebnis! Und dann bekomm ich die Werbung nicht mal mehr weg! hab die App dann neu starten können inklusive die Rechnung nochmal neu eintippen!!!!
Ich hoffe das sich des Tablet nur aufgehängt hat und nicht an der App lag und förmlich gut dass ich nicht viele Zahlen eintippen musste. 
Die Werbung kann ja auch nach dem das Ergebnis angezeigt wurde eingeblendet werden.

### 1/5 — Troppe publicita

*2023-12-29, version 2.0.4*

Troppe pubblicità

### 1/5 — Ne pas acheter

*2022-05-26*

Ce calculateur n’est utilisable que pour les 4 opérations et encore la grille des nombres est tout sauf standard. On peut oublier la partie scientifique. La logique d’utilisation n’a rien à voir avec les calculatrices habituelles et ne présente aucun intérêt !
Je préférerais me faire rembourser. J’utiliserai la calculatrice de l’iPhone

### 1/5 — Не вздумайте покупать это

*2022-02-07*

Платная версия требует дать согласие на слежку за вами. Иначе невозможно пользоваться.

### 1/5 — Rechnet falsch

*2021-10-26*

100+19%=100,19    ……und das soll richtig sein?.!!
Sofort wieder deinstalliert

### 1/5 — Prozentrechnung

*2021-04-24*

Prozentrechnung funktioniert schon mal nicht!!!!!
An der Stelle würde ich schon mal den einen Stern wieder einbehalten!

### 1/5 — Pop up adds annoying.

*2021-03-30*

I purchased it and deleted it straight away after the first pop up advertisement popped up.
Not putting up with adds when I’m trying to work out sums sorry.

### 1/5 — Confused

*2021-03-21*

Advertising is a huge negative ... sorry

### 2/5 — Esta fallando

*2023-11-02, version 2.0.4*

No funciona el historial, haces operaciones pero después no aparecen en el historial. Tarda en abrir la app, es algo lenta
