Reminders are not arriving
Check that notifications are allowed for HABIT in your phone's settings. On Android, some manufacturers (Xiaomi, Samsung, Huawei, OnePlus and others) stop apps in the background to save battery; allow HABIT to run in the background and set its battery use to unrestricted. Opening the app re-schedules every reminder.
My habits are not on my other phone
Sign in with the same account on both. The free plan syncs on two devices; Settings → Devices shows which ones, and lets you remove one.
Restoring a purchase
Open the Pro screen and tap Restore. Pro follows your account, so it also works on a phone from the other platform once you sign in.
Cancelling a subscription
On an iPhone: Settings → your name → Subscriptions. On Android: Play Store → your profile → Payments & subscriptions → Subscriptions.
Deleting your account
