### 2/5 — History doesn’t work

*2024-04-24*

Just stuck on loading

### 1/5 — Terrible

*2023-05-15*

The numbers on this app or so small I can barely see them even with my reading glasses on. Plus it was so difficult to figure out how to add even just 10 items on an invoice bill. I’ll keep looking for another app to use.

### 1/5 — Waste of time

*2022-05-31*

Downloading this app was a waste of my time. The description didn’t bother to explain that it does not work locally on your phone, you need to log in with your Google account. But log into WHAT? It doesn’t say. No thanks.

It is also strange that none of the negative reviews showed up in the App Store. 

This was a waste of my time to download and try. Are there any voice-activated calculators that work locally just on your phone?

### 5/5 — Great tool!

*2021-07-27*

I have to do simple calculations but long strings of two and three digit numbers, that would take several minutes to enter, instead I can speak what I want, and it is ready in a fraction of the time. Even better totally free, and currently no adds.

**Developer response:** Thank you Martin for your review. Precisely for the reasons you mentioned, Flash is now being used in 23 countries around the world and continuing to grow.

Thank you for your support!
