There’s one bug though: you can’t make a calculation with a number starting with a decimal.For example, I need to purposely underdevelop a roll of film by 40%, so (N x .6) where N= the base time I’d use to properly develop a roll, in this case 7 minutes. So in the app I want to type "7m x .6” but it won’t let me enter the “.” . A workaround is to type “7mx6⬅️.6” where ⬅️ is the backspace. It then properly shows the formula at the top like so:7m x .6=Fix that and I’ll upgrade my rating to 5 stars :)

Great and very useful application if you are looking calculate the time meticulously. It helps in travel, to see how much you spend on each activity if you're a business person. It's the easiest way to organize with minute precision. Widely recommended.!

love this calculator since it's like a normal calculator and easy to use and very organized. searched for something like this for a long time for my business and glad to find this app. Great job on making this!

Best application I found after purchasing and trying so many. I have these suggestions:1) Application doesn't offer any help to understand functions.2) Application doesn't give an option to write concerns to developer.3) Sometimes calculations are way off. 4) No way to post an event in the calendar that will reoccur every x days, x hours, x minutes, x seconds as calculated by the app.Still it is the best and I hope the developer reads my suggestions.
