CalcGate | App Lock with Math

CalcGate is a screen time control app designed for people who want to break the habit of opening distracting apps without thinking.

Have you ever opened social media “just for a minute,” only to lose track of time?
Do you find yourself checking your phone when you should be studying, working, or focusing?
Do app limits feel too easy to ignore or turn off?

CalcGate adds a simple but effective moment of friction before you can reopen restricted apps.

Choose the apps or app categories you want to limit, start a lock, and CalcGate will require you to solve math challenges before access can be restored early. Unlike blockers that can be dismissed instantly, CalcGate is designed to make you pause and ask yourself: “Do I really want to open this app right now?”

To unlock early, every math problem must be answered correctly. If you make a mistake, your progress resets and the challenge starts again from the beginning. This small hurdle helps interrupt automatic habits like repeatedly opening social media, video apps, games, or other distractions without thinking.

CalcGate is useful for study sessions, deep work, productivity, reading, reducing late-night scrolling, managing screen time, and building healthier digital routines.

Key features:
・Restrict selected apps or app categories
・Start instant locks anytime
・Create recurring daily lock schedules
・Unlock early by solving math challenges
・Customize challenge difficulty and question count
・Reset progress after incorrect answers

CalcGate is not about completely avoiding your phone.
It is about using your phone more intentionally.

Whether you want to improve focus, study without distractions, reduce social media overuse, build better habits, or create a healthier relationship with your device, CalcGate helps you pause before you tap.
