Great calculator, moving from Galaxy s8 to 1+ i was really missing some added functionality of the Samsung calculator like conversions and the simplest thing like moving the cursor into a current operation you are doing. This BY FAR exceed any use case i might have for it! Also to support the developer i had to purchase the matte black and red MKBHD since I'm a fan of both this app and the YouTuber! Congrats, really well done!
Excellent app. Only one very annoying thing. When the clear button ia hit a message appears in the lower part of the screen, that covers some buttons (0, enter, etc.) for some time, which makes using it slow. Please make it an option!
Great app. Could do with some better operations when converting bases (two's complement, one's complement, etc.)
What a difference this calculator makes. It is light-years ahead of others. The search for a complete surgical calculator should logically stop here. Highly recommended
Brilliant scientific calculator for all purposes including unit conversions
Very good. Although the grapher is a little clumsy. Add a complex grapher too?
Great job, guys! Really nice stuff for technical students!
Calcution history should store last 50 calculations done.. No. Of digits should be more in result calculation before converting in 10^ ..
Just what i need, and was looking for.
solid calcator app
what is needed in a calculator
One of the best
The buttons get way small when turned in landscape. Otherwise, it's a great looking app.
App always gives an error when I try to enter an ln(x) in the graph. Has been a problem for a while now. 5stars will be back when this is fixed :)
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. No auto dark mode.
Would like option to switch clear button instead of having to swipe up
Nice calculator app and the widget is very convenient
Does everything I need.
The perfect calculator app.
Easy to use-thanks
Thank you!..😀
I've tried lots of calculators but they all stock in some way. This one however is great, and free isn't a price I can assure with. Recently this has begun to bug me, every time I clear the screen there is a notification at the bottom that obscures the bottom row of buttons. The notification is slow to disappear meaning I have to pause and wait for it to clear. Frustrating, and needless. Just leave a little more space at the bottom for the notification and there would be no issue. Grrr. I reduced my rating for this.
I started using this app for calculation and conversion; easy to use while covering all my needs and we'll set. Thanks a lot
I bought the pro version long ago and in the app thatworks fine but the widget seems never recognize that, it just keep showing hit the unlock button and buy it.
I just wish the text and the numbers were larger
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
Great app and it's my default calculator. Could do with some tweaks, even on big font, the font is way too small on my GS8. Would like to be able to make tip section bigger, maybe use the space from the memory functions when they are turned off rather than stretching the bottom bigger. Get rid of the long click to edit text, make than info a tute on start, as it is annoying to clear it each time you want to edit. Not sure what the deg indicator adds, just uses valuable space, put it in the advanced dropdown.
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.
I really really love this app.. Because it shows history on home page and very easy to copy them.. But there is no "," separator and themes are way too clean...!
