Read full description

For everyone who can't stop saying "just one more scroll." AcornLock is a self-control app that uses Apple's official Screen Time API to genuinely block the apps you choose. What makes it different from typical app blockers? There's a real cost to unlocking. When you crave the apps you've locked, just shake your phone. They'll unlock for a set time—but at a price. The acorns your squirrel has been quietly collecting? Some of them vanish at random. "Wait, did I just lose my rare one…?" That moment of loss puts a gentle brake on your impulses. Tired of apps that only ask you to grit your teeth and resist? AcornLock turns the time you don't spend on your phone into something worth collecting. Built for people who: ・Lose hours to Instagram, TikTok, X, or YouTube ・Want to change habits through gameplay, not pure willpower ・Love collecting cute things CORE FEATURES ■ Real blocking with Screen Time control Powered by Apple's official Family Controls API, your chosen apps are blocked the moment you hit your limit. No relying on willpower alone. ■ A squirrel that collects for you While your selected apps are under restriction, a squirrel quietly gathers acorns in the background. They pile up while you live your life. ■ Shake to unlock = lose your acorns To unlock, just shake your phone. But 50% of your unjarred acorns vanish at random. ■ Collect acorns From everyday brown acorns to legendary rainbow ones, every drop is a small surprise. ■ Seal them in jars for permanent safekeeping Reach 50 acorns and you can seal them in a jar. Jarred acorns are safe forever, even when you shake to unlock. ■ A wooden shelf of your wins Completed jars line up on your wooden shelf, a visible record of your self-discipline. One jar = about a week of staying strong. REWARDS FOR STICKING WITH IT ・Streaks: Every day you stay under the limit adds to your streak ・Tier 0 to 5: Climb the tiers as your streak grows, boosting your odds of rare acorns FLEXIBLE LIMIT SETTINGS ・Pick multiple apps and categories with Apple's Family Activity Picker ・Set your daily time limit however you want ・Adjust how long the unlock lasts before the block returns ・Choose between Shake or Scratch unlock methods PREMIUM For people serious about changing: ・Hard Mode: Triple the unlock barrier. Lose 100% of your unjarred acorns on every unlock. ・Streak Protection: Auto-saves your streak once a month if you slip ・Larger Acorn Stock: Hold up to 500 acorns instead of the free 50 ・Unlimited Shelf Display: See every jar you've ever made ・Choose from three plans: weekly, yearly, or one-time purchase MORE FEATURES Keep an eye on your acorn count and streak right from your Home Screen widget. Take back the distance between you and your phone, one acorn at a time.

About

When Again?

Read full description

"When did I last do that?" Bike oil changes, haircuts, salon visits, AC cleaning, doctor appointments, pet care — things you do again and again, but once enough time passes, you can't remember when you last did them. When Again? clears up that little everyday question with a single tap. Just log the date. The app automatically counts the days since you last did it, learns your average interval from your own records, and gives you a heads-up when it's about time. ■ Who it's for ・People who forget when their bike or car was last serviced ・Anyone managing regular salon, hair, or nail appointments ・People tracking doctor visits, medication, or health habits ・Anyone who wants to stop thinking "wow, it's already been a while" ・People who want to start right away — no account needed ■ Key features ◎ See the days at a glance Your items line up on the home screen, each with a badge showing how many days since you last did it. What needs doing now is obvious. ◎ "About time" reminders, automatically The app learns your average interval from your records, gathers the items coming due at the top of the home screen, and reminds you with notifications too. ◎ Track anything Use the preset categories or add your own with custom icons and colors. From bike maintenance to beauty to health — manage it all in one app. ◎ Photos, tags, amounts, and notes It's more than a date log. Add up to 5 photos, tags, the amount you spent, and notes to each record — so you can look back on what state it was in last time and how much it cost. ◎ Detailed history and stats The detail screen shows stats like "since last time," "average interval," and totals, plus a month-by-month timeline. ◎ Search Search across notes, tags, and item names to find past records instantly. ◎ Easy backup Save and restore all your records to a file (photos included). CSV export is also supported. ◎ Dark mode Choose system, light, or dark. ■ Privacy first All your records are stored only on your device. No account, no login. We never send your records to a server — so you can start with peace of mind. ■ Pricing The core features are free. Some premium features are available via a one-time in-app purchase. Leave your everyday "when was that again?" to When Again?
