Awaken, Hunter. The System has chosen you. Turn your daily habits into RPG quests. Complete 5 quests each day, level up your stats, rise from E to Sovereign, and summon an echo army through streaks. Built for people who need their habits to feel like something worth doing. Track your habits like a hero and make discipline something you want to grind. --- HOW IT WORKS --- The System, your personal habit tracker, assigns 5 daily quests, each tied to a core stat: - Strength: Push-ups, running, workouts - Intelligence: Reading, learning, deep focus - Vitality: Sleep, hydration, nutrition - Perception: Meditation, journaling, mindfulness - Discipline: Planning, consistency, willpower Complete quests to earn XP. Level up. Rank up. The longer your streak, the more XP you earn. --- FEATURES --- - 50+ curated quests across 5 stat categories - Tiered difficulty that scales with your rank (E through A) - Stat pentagon radar chart to visualise your growth - Echo Army: 7-day streaks summon echo soldiers - Dramatic rank-up animations (E > D > C > B > A > S > National > Sovereign) - System-style notifications and UI - Works offline. No account, no sign-up --- PREMIUM ($4.99/mo) --- - Unlimited custom quests - Detailed stat analytics and trends - Echo cosmetics - Streak insurance (miss 1 day without breaking your streak) - Hunter card export (share your stats) No social feeds. No comparison. Just you, your quests, and the grind. --- PRIVACY --- Your quests, stats and streak are stored on your device. There is no account and no sign-up. The app sends anonymous usage data, so we can see which quests get done and where hunters get stuck. It is tied to a random ID for the install, not to you. If you write your own quest, its name, description and tier targets are sent too, so the built-in list can grow into what hunters ask for. The app says so before you write one. Nothing else you type leaves your phone. --- LEGAL --- Privacy Policy: https://inzention.com/privacy-policy Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
DoomIt

Other apps block your phone. This one does too — but it lets you earn the time first. You start with a small daily budget. Everything beyond that, you earn. Two ways to do it. THE NIGHT Set a night window, say 10 PM to 7 AM. Inside it, the apps you picked are closed. Every hour the phone stays down is worth a few minutes the next morning. Not all-or-nothing: reach for it at 3 AM and you only lose the hours after that — not the whole night. THE BODY Push-ups, squats, plank, steps. Every exercise credits minutes right away. Want to scroll now? Do the push-ups now. The camera counts along — entirely on your device. No image is stored, none is ever sent. THE STREAK Clear both daily challenges in a day and the streak lives on. It's the only thing that carries past midnight — after five days held, you collect the minutes. A joker saves it across exactly one missed day. THE RATE IS FIXED What a night hour pays and what an exercise is worth is built in. An exchange rate you can adjust yourself isn't one. YOUR HISTORY For every day it shows what you earned and what you spent. Every minute has an origin. WHAT STAYS ON YOUR DEVICE Which apps you block never leaves the device — iOS only hands the app anonymous tokens; it can't see what you picked. No sign-up, no tracking, no ads. THE WIDGET IS THE APP Remaining minutes right on your home screen. Our idea of success is unusual: we want you to open the app less, not more. Doomit uses Apple Screen Time (Family Controls) to lock the apps you choose during your night window. https://doomit.app/terms
