### 5/5 — Best calculator app!

*2016-10-01*

This is the best calculator I have come across. It lets you see a record of your calculations, which really helps you track and tally easily.

### 5/5 — Excellent!

*2016-09-29*

Great app!

### 5/5 — Fantastic App

### 1/5 — Gut

*2016-10-25*

Eigentlich hat dieses Programm fünf Sterne verdient, aber ich kann die Ergebnisse nicht irgendwo speichern. Ich muß von meinem Bildschirm ein Foto machen, damit ich die Rechenschritte festhalten kann.
Ich werde dieses Programm löschen, zeigt kein Komma an.

### 1/5 — Achtung: Rechenfehler

*2016-10-22*

Leider verweist der Supportlink nur auf die Webseite, daher hier:
100-5% = 95 Richtig!
10-5% = 95 Falsch. 
Das darf nicht passieren. Was wird wohl noch alles nicht richtig berechnet?

### 2/5 — History Not Kept

*2020-12-14*

This was my “go to” calculator. But after a recent update, the history disappears. Is that now a purchase feature?

Sent email to developer. He/She followed up but after my reply, nothing!

### 2/5 — iPad Air 2 widget problem

*2017-02-20*

iPad Air 2 10.2.1 widget screen resolution problem. Please fix. Thanks.

### 3/5 — Backspace key is missing

*2023-06-28*

I would like this app, but the backspace key for correction is missing. Also, Delete All or Clear all should be included in the front-keyboard, it should be under user's fingers, easy to click on. 

In general, this app needs improvements and additional easy-to-features.

Initiative is good. I might reinstall it once it's improved. Thanks for this app.

### 4/5 — Clean the widget design please

*2023-09-04*

Hi, this is a super and fast calc app, but I would like that you redesign the bottoms of the widget (+ - % X) without a white bar; this cause me a big confusion! Please I hope you can fix this issue.

### 4/5 — Very nice App.

*2017-01-14*

I have been using it for a few weeks now. The feature I most like is the calculations tape which is fabulous. The reason for 4 star instead of 5 star is that the developer has not contacted me back in reply to my email.

### 5/5 — CalcFast Is Efficient, Good Looking

*2023-06-16*

CalcFast is simple to use and works great. The calculator looks good on both my iPad and iPhone. For me this calculator is much nicer than the stock calculator supplied with the iPhone. My thanks to the developer for an excellent app that is easy to use. Job well done!

### 5/5 — Calc Fast simplicity hits all 5 stars

*2021-12-02*

Exactly what I was looking for in my calc app.  Records are kept or deleted in a simple yet secure fashion.  Historical calculations are simply to find.  Very basic but it seems to calculate my larger commission amounts just fine.
