Ratings and Reviews
Nice, Fast, Easy, Advanced
I’ve tried a large number of calculators and settled on this one as my main ‘go to’ calculator. Definitely worth recommending.
Potentially good but impossible to find out how it works
There is no mention of the app at the website ( has it been deprecated?) the ‘help’ you get when you load it has no words so is meaningless and you aren’t even told what the app is called ( given the logo just has the word CALC). Developers that offer you rich features without any clear means to invoke them and no written helpfile are just wasting your money. Trying to find how to invoke the history is impossible even though it did show this feature was there. Very poor experience.
Developer Response ,
Anni, we’re really sorry to hear about your experience - there ought to be a tutorial the first time you start the app, did you not see one pop up? Please tap and hold the top left “options” button to get a quick access to UserVoice where you can reach out for KB or support.
Require more money again
I brought it and now it requires more money after update.
Developer Response ,
Please contact us via email or UserVoice in the app to remedy your situation.
