I would rate this app 5 stars except I hate the way it scrambles all your tasks every time you change time zones. It's absolutely maddening if you have a lot of tasks because you'll be forced to re-priotitize every time. Going coast to coast with a layover and you'll be doing it three times. Ugh. [Update] Constantly crashing on my Galaxy Note 9 now. Like 20+ times a day.
