Жаль не совершенствуется. Очень удобный!

### 3/5 — No notes there anymore.

*2026-02-18, version 2.65*

What happened to my notes. I didn’t wipe them off, so they should still be there.

### 1/5 — Worst

*2025-11-26, version 2.65*

I won’t download if I would have knew that it is not proper calculator for a single pence, not worth at all

### 5/5 — Juste parfaite 🤩

### 5/5 — Reasonably priced (.99)

*2025-09-02, version 2.65*

Nice to find a reasonably priced calculator for my iPad that doesn’t track personal information and only costs 99 cents. 
Well done!

### 1/5 — The input box is horrifyingly annoying

*2025-08-02, version 2.65*

If I type on the physical keyboard instead of using the screen buttons, the app pops up an input box. This box doesn't support thousand separator making it impossible to type large numbers without having to keep track of the number of digits already entered. WHY? I regret buying the pro version of such a poorly designed app.

### 5/5 — Does exactly what you want it to do

*2025-05-10, version 2.65*

Works great, no crashes. No ads and it’s only $1.99 AUD. Tried heaps of calculator apps and this is my favourite. Recommend it

I’ve been using this calculator app for years and love it. Bought a Macbook and discovered that it can’t be used there. So sad

### 5/5 — Cal review

*2024-11-29, version 2.65*
