SIMPLY THE BEST DATE / TIME CALC IN THE APP STORE!

I’ve been with this app since the beginning. It had a rough start, but I’m very glad I’ve stuck with it through its development.
 As it stands today; it is absolutely the finest date & time calculator in the App Store. Clean, multi-featured GUI. All the functionality you could need. Worth every penny. Thanks for your hard work on this dev!

Response from developer

Thanks for the feedback (and sorry I didn’t get back to you sooner). I’ve just released an update to the app (Whenr Whenr 2.0.0) that adds multiply and divide - so you can now take an interval, like 5 hours, and divide it by 8 (to get 37 minutes 30 seconds), or multiply 12 minutes 30 seconds by 7 (to get 1 hour 27 minutes 30 seconds). I’ve also added support for dates (not just times) as well as unit conversions. It’s a big update - I hope you’ll check it out!

AM I MISSING SOMETHING?!

No multiply or divide!
