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.

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.

After they change to a subscription mode, I unistall the app. It is not fair with former users to do that! Apple Store could must obligate developers to keep All access to their app to users that bought apps before changing apps to subscription format.
