Good news! The Perx app works everywhere in this beautiful world 🌎 (we still haven't reached the 🌙 though , sorry…) and it should also work without a network connection.
About the time of your reminders:
The way the app works is that it detects the time on your phone and it sends you a reminder when the scheduled time for your task matches the time on your phone. So, for those of you who are going to a different timezone: if the settings on your phone are to adjust time automatically based on your location, the Perx app will remind you at your new timezone. If not, the Perx app will keep sending your reminders based on your normal timezone.
