About

WhyMin Screen Time

Features
Read full description

WhyMin is a focus companion that asks "why are you opening this?" and "for how many minutes?" before the apps you open on autopilot. Block the apps you choose — video, social, browsers — with Screen Time. When you try to open one, WhyMin steps in and lets you use it temporarily once you've decided your reason and time. Pick a reason like "Look something up", "Reply or message", "Take a short break", or "Just because", then set a time from 3 to 60 minutes. When time runs out, the guarded apps are blocked again automatically. Each reason button shows how many times you've opened apps today, and the check-in screen shows today's total usage time for your guarded apps — so you notice the "just because" moments. WhyMin isn't about banning your phone. Use it when you need it; only cut the time you spend on autopilot. Main features (free): - A check-in that asks your reason before you open - Session lengths of 3 / 5 / 10 / 20 / 30 / 60 minutes - Block and temporarily unlock one guarded app with Screen Time - Daily counts per reason and today's total usage time - A setup guide for the Shortcuts automation - Countdown display during a session - Dynamic Island / Live Activity support - A simple design that keeps everything on your device WhyMin Premium (optional in-app purchase): - Guard two or more apps - Rewrite the check-in reasons in your own words - Set six "How many minutes?" options per reason - Daily limits on check-ins and total usage time - Home Screen widget Recommended if you: - Open social or video apps without thinking - Want to protect your focus time - Prefer balance over quitting your phone entirely - Want a gentle limit on just the apps you choose Privacy: WhyMin stores your selected apps and session data on your device.
