Posture Reminder

It's free, no ads, and doesn't force you to make an account. I've used this for about a week, using 15 minute reminders for 12 hours a day, this has helped me make a small but noticeable amount of progress to fixing my posture. The app does what it says and it's refreshing to see an app that's here to actually help you and isn't just a cash grab. It's a simple app, but I will be donating if I see long term results (if there is a way to)

Avoid... Notifications only work until your turn your phone off or use airplane mode and then they stop and nothing restarts them!! Notifications are set to every 30 minutes, yet it goes off every minute, sometimes multiple times a minute. Contacted app developer and had zero reply. Deleting now to find something else.

Unfortunately the new update gives me a notification every minute instead of the preset intervals. While previously I had to reopen the app every day, the notifications would arrive at the set intervals. Before, it was working with a workaround. Now it's unusable.
