Screen time, finally on your terms. Math Gate turns "five more minutes!" into real learning. Before your kids can open the apps you choose, they answer a few quick, age-perfect questions in the subject you pick: math, reading, grammar, science or art. Get them right, earn the time — and when it's up, the apps lock again automatically. Learning first, screen time second. Meet the penguin crew! Five friendly guides turn practice into play and cheer kids on through every challenge: • Cosmo — Math: addition, subtraction, multiplication and division • Juno — Reading: stories, phonics, word meaning and inference • Quill — Grammar: parts of speech, punctuation and sentences • Nova — Science: living things, the human body, Earth, space and energy • Iris — Art: color, the elements of art, tools and artists WHY PARENTS CHOOSE MATH GATE • Five subjects, one app — pick a subject for each child and switch anytime. • You decide what's locked — any apps or whole categories. The lock holds even when Math Gate is closed. • Auto-unlock on your terms — set the reward time; apps re-lock when it runs out. • Real progress, at a glance — accuracy by topic, daily streaks, most-missed questions, and reward badges. • Always age-perfect — five levels from age 5 to 13+ in every subject. • Read it to me — kids can hear reading, grammar, science and art questions read aloud. • Truly private — no ads, no trackers, no accounts, no data collection. Everything stays on your device. • Built for families — a separate profile, subject, difficulty, and time limit for each child. • Parent-locked — your settings sit safely behind Face ID. HOW IT WORKS Set it up once — create a profile, choose a subject, pick the apps to lock, and set difficulty and reward time. Kids learn to unlock — their penguin guide serves a short set of questions; correct answers earn the screen time. Time's up, learning's back — apps re-lock on their own; a quick new challenge unlocks them again. Turn everyday screen time into a daily learning habit — without the nagging. SUBSCRIPTION DETAILS Math Gate is free to set up.

EarnTime
Read full descriptionHide full description
Make learning a small, positive part of your screen-time routine. EarnTime combines short math, logic, and English challenges with optional time in selected apps. Use it for yourself without an EarnTime account, or set up a routine for your family. START FOR YOURSELF Choose Start for Myself to practice immediately. An EarnTime account and Family Sharing are not required for personal use. You can optionally authorize Apple Screen Time on your device and choose apps to limit. Personal app limits can be turned off from EarnTime. VARIED, OFFLINE PRACTICE Questions include arithmetic, patterns, logic, vocabulary, spelling, and grammar across grade and difficulty levels. Questions and answer choices are randomized. Incorrect answers keep you on the question with helpful feedback and Try Again. Practice works offline, builds learning progress, and does not award screen-time minutes. LEARN, THEN EARN Once app limits are configured, tap Earn minutes on your EarnTime home screen and complete a challenge. Each new reward starts one countdown for all selected apps, so you can switch between them. The countdown continues when you leave EarnTime or put your phone down. Earlier device usage does not reduce a new reward. Daily limits, cooldowns, and quiet hours still apply. Optional ending sounds depend on iOS notification, Silent mode, and Focus settings. SEE YOUR PROGRESS See correct answers for today, yesterday, and all time, plus a seven-day chart and daily learning history. Build a learning streak, earn XP, and reach new levels. Levels do not change your screen-time limits. Learning history is saved on this device; deleting the app or changing devices can remove local history. SET UP YOUR FAMILY Guardians sign in with Apple and pair a child's device using a QR code or manual code. Children do not need an EarnTime email or password. Child Screen Time authorization requires the child's own Apple Account in the guardian's Apple Family Sharing group. Do not share an Apple Account or password. KEEP CONTROL Adjust the learning routine and app limits. Selected app information stays on the device. Guardian account deletion is available under Account. EarnTime is free, with no advertising, social feed, or in-app purchases. Requires iOS or iPadOS 26.5 or later. EarnTime manages only its own app restrictions; separate Apple Screen Time limits or restrictions from another app may still apply. Questions or feedback: support@imprvhealth.com

Verdict
The clearest difference is in-app purchases: EarnTime at none against Math Gate's 3. Math Gate's advantage is iOS requirement (16.4 vs 26.5). On price, ads and device support there is nothing between them.
