## What is Nepsis?

Nepsis puts a little space between you and the apps that pull you in.

Choose the apps you want to step back from, such as social feeds, short videos or games, and Nepsis locks them using Apple's Screen Time. When you really do want one back, you earn it: solve a short round with your brain and the app opens for a few minutes. Then it locks itself again.

No guilt and no lectures. Just a pause long enough to ask whether you actually want to open it, and a small win for your brain when you do.

EARN IT WITH YOUR BRAIN
- Mental math, clearly typeset: fractions, powers, roots, percentages
- Puzzles: memory, logic, shapes to turn, spot the flaw, estimates, anagrams
- Body: name the muscles, what they do and the bones
- Quick quizzes: more than 4,800 questions, from general knowledge to physics, law and history
- Reading: a short passage, then a question about it

Difficulty adapts as you go, and most rounds take under a minute.

OPENS TO A CHALLENGE, NOT THE FEED
With a Shortcuts automation, opening a locked app takes you straight to a calm, full-screen pause in Nepsis with the round ready to start.

IT LOCKS ITSELF AGAIN
Every unlock is a short window, 5 minutes by default or anywhere from 1 to 30. When it ends, the app locks again. Close it early and the minutes you didn't use wait for you until midnight.

COINS FOR PRACTICE
Train any time, even with nothing locked. Right answers earn coins, and 50 coins trade for 5 minutes of earned time, up to 30 minutes a day. Coins are earned only by training; they can't be bought.

AS STRICT AS YOU LIKE
- Cooldown: several wrong answers in a row pause challenges for a while
- Done for today: keep everything locked until tomorrow, on every device you use

FRIENDS WHO HOLD THE KEY (OPTIONAL)
Add a friend by their handle or invite link. A friend can give you 5, 10 or 15 minutes with a six-digit code or send them to your phone, and you can ask them for a few minutes. Turn on Only a friend can unlock and challenges rest until a friend opens things for you. Friends see your name and handle, never your stats or your apps.

YOUR AI ASSISTANT (OPTIONAL)
Link an AI assistant that supports connectors to ask about your progress. You can also give it a trusted code for real emergencies, and allow it to open apps you pick for a timed work session. Only you can turn these on, and each use is listed in the app.

PLAY ON OTHER DEVICES
Connect a tablet or a browser to play the same games. Results there move your levels only, never unlock anything.

SEE THE HABIT FORM
A score from 0 to 1000 for each game, with 30- and 90-day trends, your strongest quiz topics and milestone stickers. Training ratings, not an IQ test. Widgets show your streak.

IPHONE AND IPAD
Layouts made for each, with progress, Premium, settings and Done for today following your account. Screen Time keeps each device's chosen apps on that device, so you pick them once per device.

PRICING
Nepsis is free for up to 3 apps on each device, with every challenge, level, stat and widget included.

Nepsis Premium lets you lock as many apps and categories as you like, on all your devices:
- $2.99 every 3 months, an auto-renewing subscription that starts with a 7-day free trial
- $19.99 once, for lifetime access

Prices may differ by country. If you start the free trial and do not cancel at least 24 hours before it ends, $2.99 is charged to your Apple Account and the subscription renews every 3 months unless you cancel at least 24 hours before the end of the current period. Manage or cancel it any time in your Apple Account settings.

PRIVACY
Apple's Screen Time hands Nepsis opaque tokens, not the names of your apps or how you use them, and they stay on the device. The one exception is yours to choose: apps you allow for assistant work sessions share their names with our server. No ads, no tracking, nothing sold.
