The feed is behind a math problem now.

Pick the apps that eat your day. MathGate puts a math problem in front of them, and only a right answer opens the door.

3x + 7 = 22. Solve for x.

Try it. This is the real mechanic, the apps behind it are just for the demo.

Three tries. That's the whole deal.

No infinite guessing, no dead end either. Here is exactly what happens between tapping a locked app and getting in.

01

A problem appears

AlwaysOne of five subjects, picked for the session before you see it.
02

First try

RightApps open for the duration you set. Done.
WrongA hint appears. No penalty yet, just a nudge.
03

Second try

RightApps open. The hint did its job.
WrongMathGate shows the answer and moves you to the next problem. The gate stays shut.
Stuck? Wait 15 seconds on any problem and one skip becomes available. Just one, per session, so it is not a free way through.

The problem

Blocking apps just builds a wall you dismiss.

A blocker that only shows a warning screen doesn't ask anything of you, so you tap through it without a thought. MathGate makes you earn the unlock with a real problem you have to work out. The friction is the feature, not a bug to route around.

The fix

Solve it and the door opens. Skip it and that counts too.

Pick the apps that eat your day and MathGate stands a math problem in front of each one. Solve it and the app opens for as long as you chose. Close the gate and walk away instead, and MathGate counts that as a win, right alongside every problem you get right.

Inside the gate

Solving a problem, choosing what gets blocked, and the stats that keep score. As they actually look.

What's actually in the app

01

Real app blocking

Choose the apps you want gated with Apple Screen Time. MathGate stands a problem in front of them, not a nag screen you can swipe past.

02

Five subjects

Fractions, long division, algebra, percentages, geometry. Free sessions draw from all five.

03

Streak tracking

Every solved session adds to your streak, right on the home screen next to your best run.

04

Unlock duration, your call

Pro lets you choose 15 minutes, 30 minutes, 1 hour, or 2 hours before the gate locks again.

05

Accuracy stats

See how many problems you solved today and your accuracy percentage without digging through menus.

06

One skip per session

Stuck on a problem? Wait it out and a single skip appears. Just one, so it is not a free bypass.

Questions

Yes. MathGate uses Apple's Screen Time (Family Controls) framework to actually restrict the apps you pick. Without that permission granted in Settings, it has no way to lock anything.
