These apps literally plant a tree when you stay off your phone.
If you leave the app?
The tree dies.
Yes, you become personally responsible for virtual deforestation.
Great if guilt works better on you than discipline.
Also works with friends, which means if you cave → everyone’s tree dies → now you’re a villain.
Instant accountability.
It’s the most effective app blocker out there. Some settings you can’t even bypass, to guarantee lockdown for those last-minute studies.
Downside: Costs $2,50 per month.
