DoomGuard
Read full descriptionHide full description
You open THAT APP for a second. Forty minutes later, you're still there. DoomGuard is the screen time app that catches you mid-scroll โ not before, not after, but while a quick check is turning into a spiral. Like a friend who says "hey, you're doing it again" at exactly the right moment. No hard blocks. No app bans. Just a nudge, in a voice you actually picked. YOUR RHYTHM, YOUR RULES Forget "45 minutes a day." Open your apps as often as you like โ DoomGuard nudges you by frequency, not a daily cap. Every reopen counts on its own, so the 15th check of the day gets caught too. iOS Screen Time just adds up your whole day and pings you once. We watch the session you're actually in. CHOOSE YOUR PERSONA Pick the voice that gets through to you. Standard stays steady and clear. Roast calls you out. Cyberpunk glitches you back to reality. Zen brings you back to center. YOUR SCHEDULE, YOUR APPS Go Premium for stricter evenings and lighter weekends. Guard unlimited apps, set Morning / Afternoon / Evening windows, split weekdays from weekends, and see detailed session insights. TAKE A REAL BREAK Put your phone down for 10 minutes and we treat your next scroll as a fresh start โ no instant nudge. We call it Rollover. We're not punishing you for stepping away. DoomGuard is for self-aware people who use social media for work, inspiration, and connection โ but know when it's tipping into a doomscrolling spiral.

MathGate

Pick the apps that eat your day. MathGate puts a math problem in front of them. Tap one and you get a question instead of a feed. Solve it and the app opens for as long as you chose. Close it and walk away, and MathGate counts that as a win. YOU SET THE GATE Set anywhere from 1 to 10 problems per session. Choose how long an unlock lasts: 15 minutes, 30 minutes, 1 hour, or 2 hours. Pick your subjects: fractions, long division, algebra, percentages, geometry. HOW THE PROBLEMS WORK You get three tries. Miss the first and you get a hint. Miss again and MathGate shows you the answer. One skip per session, so waiting out the timer is not a free pass. WHAT IT TRACKS Day streak and best streak, with one grace day a month so a single slip does not wipe the board. Problems solved today and your accuracy. A running count of the times you hit the gate and chose to walk away instead. Optional evening reminder to keep the streak alive, and a Sunday recap of the distracted opens you dodged that week. Everything stays on your iPhone. No account, no sign up, no server, no analytics. MathGate cannot see which apps you picked. MATHGATE PRO MathGate runs on a MathGate Pro subscription, offered after setup: $2.99 per week, or $29.99 per year with a 7-day free trial for new subscribers. Prices vary by region and are shown in the app before you buy. If you bought the earlier one-time Pro unlock, you keep Pro. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless it is canceled at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours before the period ends. If you start a free trial, you are charged when it ends unless you cancel at least 24 hours before. Manage or cancel in Settings > Apple Account > Subscriptions.
