### 1/5 — Calculator reviewing expert

*2026-01-05*

Used to have numbers that could make hello upside down but now has number 4 as a normal number 4 not as a four that looks like a h.

**Developer response:** Thank you for your feedback. We understand your observation about the number display. We’ll take this into account for future updates to improve the app experience.

### 3/5 — Decimal point problem

*2025-11-03*

I found that if I multiply a number by .5 for example the number reverts to 5 not .5 so multiplying 2 by .5 gives 10 not 1. You have to use 0.5 and not .5 for it to work.

**Developer response:** Thank you for your feedback. We appreciate the clarification and will consider improving the input handling in future updates.
