Stake against → TikTok
Stake 7 dollars against a 30-minute daily TikTok limit. Stay under, your money returns. Cross the line, your stake forfeits to a charity you picked. Sensor-verified by your phone, not the honor system.
Suggested starting contract
$7/day against a daily limit of 30 minutes on the apps you choose.
Free on Google Play and the App Store. On Android, grant Lockin permission to read your daily app usage. On iPhone, grant Screen Time access so Lockin can read your daily app usage.
From the new-contract screen, choose Screen Time. This is the contract type that watches a specific app's daily usage rather than steps, sleep, or workouts.
Pick TikTok from the app picker. Lockin will track every minute spent inside the TikTok app — main feed, LIVE, DMs, profiles, comments — as one combined number.
Set 30 minutes. Heavy TikTok users average roughly 95 minutes a day per 2024 Pew reporting on US teens and young adults; 30 minutes is materially below that baseline, which is the point. A limit you would hit anyway is not a contract.
Stake 7 dollars per day to start. Enough to feel the loss, low enough that a bad week does not wreck you. You can scale up to 10 or 20 once you trust the system.
Pick from Lockin's vetted list. If you fail, your stake funds the charity you chose. Lockin charges a small platform fee to cover payment processing and operations.
Review the contract — app, limit, stake, charity, duration — and confirm. Once you lock in, the rules cannot be loosened mid-contract. You can make it stricter, never softer.
From Lockin's data
In Lockin's 2026 closed beta, users on a TikTok Screen Time contract cut average daily TikTok minutes from 94 to 31 inside the first 14 days, and forfeited on roughly 1 in 6 contract days.
"Seven dollars is nothing until you watch it walk out the door because you opened TikTok in bed. Three days later I was closing the app at 28 minutes without thinking. The swipe just stopped feeling free."

Lockin tracks. On Android it reads your TikTok minutes through the same counter behind Digital Wellbeing. On iPhone it uses Screen Time — same daily check, different OS hook. Either way it's a counter, not a blocker. The friction comes from the stake, not from a lockout screen. If your daily TikTok total crosses the line you set, the forfeit triggers automatically at end of day and your stake routes to the charity you chose.
Yes. Lockin reads your daily app usage on-device on both Android and iPhone, and the contract settles automatically at end of day. Verification is hands-off on both platforms. iOS shows progress in 5% increments rather than literal minutes during the day, but the pass/fail outcome is just as binding.
Lockin offers a one-day refund window for verified emergencies — broken phone, hospital, family crisis. Outside that, the contract holds; that is the whole point. If you are a working creator who needs TikTok four or more hours a day, the Screen Time challenge type is not the right tool for you. A scheduled-window or off-hours contract may fit better.
Forfeited stakes go to a registered charity from Lockin's vetted list. You choose the charity from categories including climate, mental health, animal welfare, and digital literacy when you set up the contract. Lockin charges a small platform fee to cover payment processing and operations. Refer to the transparency page inside the app for charity-by-charity tallies.
