Dopamine-Tank

One water tank for your group

Only for iPhone

iPhone

Your group's phone time is water. Don't let the tank run dry. Dopamine Tank turns screen time into a game you play with friends. Your group shares one water tank. Every minute of screen time you spend drains the group's water - for everyone. When the tank runs dry, the whole group locks down: only calls and messages get through until midnight, when the tank refills. Stay afloat together: - One shared tank - your whole group's screen time drains the same water. - Locks are real but gentle - calls and messages always work. - Friends can bail you out - ask for a water ticket (with a short message) or solve a few math problems yourself. Both unlock paths are always free, on every plan, forever. - Weekly report card - a 9:16 shareable card of the week's saved screen time and your friendship streak. - Streaks & pokes - gently nudge friends who are draining the tank (3 pokes per friend per day). Subscriptions (optional): - Dopamine Tank Pro - groups of up to 5 friends, a stats dashboard, and monthly streak freezes. - Dopamine Tank Group - Pro benefits for your entire group of 5. - Lifetime - Pro forever, one-time purchase. All core features - the shared tank, lock screen, puzzle unlock, water tickets, pokes, and weekly reports - are free. Paid plans only add group size, statistics, and streak conveniences.
