Ratings and Reviews
GREAT App, very handy
I'm bad at doing date and time calculations. They are cumbersome and tedious. I use an Excel spreadsheet to make the calculations much easier.
Then I discovered "Time Calc: durations and dates". It is GREAT! This app is much easier to use than the spreadsheet, and can do much more. It has a pretty short learning curve.
Great for:
- Calculating the number of days between two dates. Or the number of hours, minutes, seconds, etc.
- Adding up total minutes and seconds of MP3 tracks to fit on a CD.
- Converting one time measure to another: X hours = how many days, weeks, minutes, seconds, hours by pressing just one key.
Nice GUI, very handy, highly recommended.
Developer Cut Features From Paid App
I purchased Tabi Calc for date calculations before the developer switched to a subscription model. Those features (that I already paid for) are now locked behind a subscription. Restoring the purchase does nothing. Fortunately, every feature this app offers is available in the iOS calculator or from Google for free.
App no longer works
I bought the app before the subscription model and now it no longer works. I cannot do the basic functionality that i paid for in the app like adding and subtracting dates. Place do not support this company until these poor business practices are fixed.
