The app looks amazing and is packed with lots of easily accessible features. I love the ability to switch between simple and advanced mode. The only problem is that the app is not the best when it comes to one-handed operation: it would be nice if I could move the numberpad towards the right side of the screen instead of it being locked on the left side

Y70%
by Y####:

The only thing holding it back from 5 stars is the widget, because every time I restart my phone the widget gets locked. Apart from that the app is well laid out without getting too complicated.

J70%
by J####:

While the app itself is useful, the widget is not. It locks up after every use even after paying for the pro version.

by Y####:

I love this app so much! Maybe give the option to make the font bigger? Or simplify the layout even more beyond the "simple" setting. But overall great app. 10/10

Y70%
by Y####:

The best. But converting negative decimal values to binary is wrong.

Y70%
by Y####:

My reasoning for 5 stars: There's a button that automatically finishes the brackets in your equation.

Simpler Taschenrechner, besser als der eingebaute, aber ohne viel Schnickschnack. Tut genau was er soll. Super.

I was downloading this with the intentions or replacing my current pop up widget with this one. The calculated is great all the features are there but there's a catch. Just to have access to the widget...not even the full app costs $3.00 ..that's just for the simple widget .....prices are a little steep for mine and many others liking but I'll keep it for a little bit and see if I want to pay that

X70%
by X####:

Love it when devs release free-version apps this good without ads. 5 stars for you dude. (Suggestion - check your pro-version pricing.. you're more expensive than Tasker)

Very very nice and modern calculator! Has matrices, unit conversion, imaginary calculations and a graph plotter. Wishes for future version: DMS - fractions - editable conversions - logical ops (AND, ASL) on binary values.

Very good

N70%
by N####:

One feature that would complete it would be an option for comma separators instead of space separators for the thousands place. An awesome paid feature would be the ability to create custom themes. Also, it would be nice if the user could move or hide certain buttons.
