You open the app "just for a second." An hour disappears. Nobody knows you want to stop more than you do. momblock is a screen-time blocker that doesn't rely on willpower. Open a blocked app and the person you chose takes over the screen — your mom, your grandpa, your partner, with their photo and their words. A face that brings you back to reality. HOW IT WORKS - Pick the apps and sites you want to quit (3 of each, free) - When you open one, their photo and message step in - You can still choose "not yet" — but it goes on the record YOU DON'T HAVE TO QUIT COMPLETELY Set a daily budget like "30 minutes a day." Reaching the limit and stopping still counts as a kept day. Watch the green days stack up on your calendar. RECORDS AND BADGES Kept-day streaks, per-app blocking trends, your risky hours, and badges for the days you held the line. STRICT MODE FOR THE SERIOUS (PLUS) Once on, protection can't be weakened. Turning it off takes a 5-second hold and a 24-hour wait. Impulses don't get a vote. PRIVACY Your photos and custom messages stay on this device. No account required. MOMBLOCK PLUS - No ads - Unlimited app blocking, up to 50 sites plus an allowlist - Register as many people as you want, and assign one per card - AI calls - Strict mode Free forever if you want (the free plan shows ads on some screens). Start with one app you wish you opened less. Terms of Use: https://momblock-support.vercel.app/en/terms Privacy Policy: https://momblock-support.vercel.app/en/privacy

Time away from your phone, turned into cute treats. OAZUKE lets you collect the time you spend away from your phone as treats. Studying, reading, work, chores — pick what you'll do and how long, then start focusing. Make it to the end without touching your phone and you'll get a cute treat. What you'll get is a surprise until you're done. ■ Collect treats Focus all the way through and you'll get one cute treat. What comes out is a surprise until you're done. Every treat you collect goes into your collection. ■ Your effort fills the jar The treats you earn pile up in this month's jar. The longer you focus, the bigger the treat. ■ A record of every day The calendar shows when and how long you focused. Your daily records and focus time are there at a glance. ■ Make the fridge your own Change the colours and add the stickers you've collected to make the fridge yours. Stickers unlock little by little as your focus time adds up. ■ Focus with only the apps you need Even while focusing, you can allow just the apps you need for studying or work. Handy for keeping your distance from social media, games and anything else you open without thinking. ■ See how far you've come Look back on your streak and your past records, and keep focusing without it feeling like a chore. For studying, for work you want to concentrate on, and for putting your phone down before bed. The more you put your phone away, the more treats you get. Why not turn holding back into a reward?
