Notifications are sent on watering days between 8-9 am local time. If you still have plants ready for water later in the day, follow up reminders are sent in the afternoon. The exact time of afternoon reminders adapts based on your behavior and the time that you tend to water your plants.
If for some reason you are not receiving watering notifications, make sure that you have reminders turned on in the app settings, and in your iPhone notification settings if you're using an iOS device.
If you continue to have issues, reach out to firstname.lastname@example.org and we’ll be happy to help get them up and running!
