I created this app for myself, to remind me every 5-15 minutes to sit up straight. It's helped my posture a bunch after a couple of days using it 🚀
Simple, does what's needed and no more.Cons:
No real cons without asking the app to be something it isn't.
I used to use a Pomodoro app for a similar thing, but stopped using that overall technique for GTD and missed the posture reminder. Enter Vatobe!Japh has used this product for one month.
