Timer on screen, the longer it is left without the user visiting other/forbidden apps, the more rewards received.
E.g. 15 minutes on the clock = “Have a coffee”.
30 minutes = “Spend 6 minutes on social media”.
If the timer is left for a significant amount of time, the user will receive free gifts.
E.g. 1 hour = “10% off Newlook discount code”.
2 hours = “Voucher for free coffee”.
3 hours = “Free week of Spotify Premium”.
4 hours = “Free movie download from Amazon”.
Additional Feature (If possible)
The app will lock the users phone screen so they cannot use other/forbidden apps for the time the timer is set to.
