Registration: Open · as of
Test Prove/n for 2 weeks. Get paid $10 CAD and enter to win the game of your choice (yes, even GTA6).
20 spots. Testing begins once all spots are filled and every registrant is approved, and everyone starts together.
For high schoolers, STEM students and graduates on Android. Use the app like you normally would, tell me what works and what breaks, and get paid when you finish.
The prize is one video game chosen by the winner: any game up to $110 CAD (includes GTA6). If a winner under 18 picks a game rated above their age, a parent or guardian has to approve it first. Prove/n is not affiliated with or sponsored by Rockstar Games, Take-Two Interactive, Sony, Microsoft or Nintendo.
What Prove/n Is.
Prove/n puts a quick STEM question between you and the apps you want to use less. You pick which apps to guard: social media, games or anything else on your phone. Open one with no minutes left and Prove/n locks it until you answer. Correct answers earn minutes of screen time, and when they run out, the app locks again.
What I want your feedback on
This tests the whole app in your everyday life, not just the questions. Tell me about crashes or bugs any time you hit one.
Setup and Sign-In
Creating your account, signing in, turning on blocking and choosing your apps. Was anything confusing or broken?
The Lock
Does it show up every time you open a guarded app? Did it ever fail, or could you get around it? Does it feel annoying, useful, or both?
The Questions
Too easy, too hard, confusing or wrong? Tap Report a problem on any question that's wrong or unclear.
Battery and Reliability
Does your battery drain faster? Does Prove/n keep working after you restart your phone, or does Android switch it off?
Who I'm Looking For.
Any of these, as long as you meet the requirements on the right.
-
STEM majors and graduates
Studying a STEM subject or economics now, or already finished.
-
University students
Majoring in engineering, computer science, math, economics, biology or chemistry.
-
High schoolers taking STEM courses
Grades 8 to 12. Must be at least 13. Parental permission required.
You'll Need All of These
-
A real Android phone (not an emulator) running Android 7.0 or newer (API 24).
To check, go to Settings > About phone > Android version. On some phones it's under Software information.
-
A Google account you use on the Play Store on that phone.
-
At least one app you use regularly and would like to use less. It can be any app on your phone.
-
One participation per person. One form, one Google account, one phone.
A Parent or Guardian Says Yes.
Download the parent or guardian consent form, have your parent or guardian sign it (on paper or digitally), and upload it with your registration form. The registration form also asks for their name and email, so please fill it in with them, not for them.
Why: joining means creating an account, sharing your email, installing an app that sees which apps you open, and getting paid. That's a lot to sign up for, so a parent or guardian should know about it and be OK with it.
What You'll Do.
Two weeks of normal phone use and three short check-ins. No special tasks.
Use It Normally
For 14 days. Just live with it and notice what works and what doesn't.
Stay In
Stay opted in and keep Prove/n installed the whole time. The lock only works while blocking is turned on, which the app walks you through during setup.
Three Check-Ins
Short questionnaires on day 1, day 7 and day 14. All three are required to get paid and enter the prize draw. Submit each one within 24 hours of getting it to earn an extra draw entry. Estimated total time for all three: 15 minutes.
Report Bugs
Optional, but it really helps. Post in the tester Discord (link TBD), or use the contact form at the bottom of this page.
Optional Bonus: Try Your Own Notes
Upload a PDF, photos of handwritten notes or pasted text, and Prove/n writes questions from them. Tick "Include questions from my notes" in the Learn tab to mix them in with your subjects. Upload notes during the test and correctly answer at least 5 questions from them to earn 1 extra draw entry.

Privacy & Permissions.
Exactly what Prove/n asks for, what stays on your phone and what reaches my server. Full details in the privacy policy.
What Prove/n asks for
-
Accessibility service (you turn it on yourself)
The part that does the locking. It sees which app is open and how long you use the apps you've chosen to guard. If you turn on habit nudges (off by default), it also notices when you switch screens or tap into a text box in a guarded app. It can't read what's on your screen or what you type. Prove/n explains this before sending you to Settings, and you can turn it off any time under Settings > Accessibility.
-
See your installed apps
Lists the apps on your home screen so you can pick which ones to guard, and opens them once you've unlocked them.
-
Internet access
To sign you in, fetch questions, grade your answers and show the leaderboards.
-
View network connection
So background syncing waits until you're online.
-
Run at startup, prevent the phone from sleeping
Added by Android's background-task library (WorkManager), so scheduled syncs (fresh questions, your Deep Focus streak) survive a restart and can finish.
-
Google Play billing
For the subscription, which goes through Google Play.
Prove/n doesn't ask for your camera, microphone, location, contacts or notifications. Android also lists one internal permission (app.proven.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION) that only lets Prove/n talk to itself.
Stays on Your Phone
On-Device- Which apps you open, when, and for how long
- Your usage patterns: reopen loops, long stretches of passive scrolling, your usual usage, and the break warnings and nudges you've had
- Your focus hours and how they went
- Your education and occupation answers from setup
App usage and focus-hours data are also kept out of Android's cloud backup and phone-to-phone transfer. If you have Android backup on, it can save your Prove/n settings (such as which apps you guard), but not that usage data.
Sent to Prove/n's Server
- Your account: name, email and password.
- Your answers, for grading. They're checked against the stored answer on the server and never sent to an AI.
- Your progress: minutes earned, correct answers and your streak of correct answers. To confirm you met the requirements, I check which days your account earned minutes.
- Your Deep Focus streak: just the number of days, for the leaderboard. Nothing else about your focus hours.
- Your username, if you set one. It's shown on the leaderboards.
- Your question settings: subjects, level and difficulty.
- Question reports you send (a reason picked from a list).
- Your Google Play purchase token, so the server can check your subscription with Google.
- Notes you upload (optional): a PDF, pasted text, or the text of photos you take (photos are read on your phone; only their text is sent). Names, emails and phone numbers are removed before an AI provider (OpenAI) writes questions from them. Your notes questions are only shown to you.
Uninstalling
After the test (or if you have to stop), long-press the Prove/n icon and tap Uninstall, or go to Settings > Apps > Prove/n > Uninstall. That removes everything stored on your phone. It doesn't delete your account on the server. To leave the closed test, open the opt-in link again and choose to leave.
Deleting Your Data
In the app, go to Settings > Delete account and type your username or email to confirm. That permanently deletes your account and everything stored with it: answers, progress, reports, notes and your leaderboard spot. Any Google Play subscription renewal is cancelled first. To have your registration form answers or anything else deleted, use the contact form at the bottom of this page.

This is a beta, and finding them is the point.

During the 14 days. Updates arrive through the Play Store.
Questions.
Do I need to be a heavy social media user?
No. You can guard any app on your phone, social media or not. Just pick at least one you use regularly, so the lock actually comes up. Normal use is exactly what I want to see.
What if my phone is older than Android 7.0?
Then the Play Store won't let you install Prove/n, so you can't take part this time. Check Settings > About phone > Android version before you apply.
Can I use an iPhone?
No. Prove/n is Android only for now.
Do I have to pay for Prove/n during the test?
No. Testing Prove/n is free.
When will I hear back?
You'll get a confirmation email as soon as you register. I'll email you again once all 20 spots are filled and everyone is approved.
Who do I contact?
Use the contact form at the bottom of this page, or ask in the tester Discord (link TBD).
Ready to Test?
Two weeks, three short check-ins, $10 CAD when you finish, and a shot at the game of your choice.
Contest Rules
- Open to residents of Canada, excluding Quebec.
- No purchase necessary. Entry is free.
- To be entered, you must meet all of these requirements. No exceptions.
- Keep Prove/n installed and stay opted in as a tester on Google Play for all 14 days.
- Be active: earn minutes in the app (answer at least one question correctly) on at least 10 of the 14 days.
- Submit all three check-in questionnaires (day 1, day 7 and day 14). Late ones still count.
- One entry for meeting all of these requirements. Bug reports don't earn entries.
- One extra entry for each check-in questionnaire submitted within 24 hours of receiving it, up to 3. A questionnaire submitted after 24 hours still counts toward the requirements but earns no extra entry.
- One extra entry for uploading your own notes during the 14 days and correctly answering at least 5 questions written from them.
- The winner is selected at random from everyone who meets the requirements, on TBD* and contacted by email.
- Answering a skill-testing question isn't needed to enter. Only the person drawn has to answer one correctly before receiving the prize: a short math question solved in order of operations (BEDMAS), such as (12 × 4) + 30 ÷ 5 − 7.
- Prize: one video game (standard edition) chosen by the winner, worth up to $110 CAD (includes Grand Theft Auto VI, Standard Edition, for PS5 or Xbox Series X|S). Approximate retail value: up to $110 CAD.
- The sponsor buys the game and ships it to the winner's address. A digital copy is sent as a boxed copy with its download code. For winners under 18, it's shipped to the address their parent or guardian provides. No cash, gift cards, store credit or other substitutes. The prize can't be transferred to someone else.
- Winners under 18 may choose any eligible game. If the game is rated above their age, a parent or guardian must approve it before they receive it.
- If the chosen game is unavailable, the winner picks another under the same rules.
- Odds of winning depend on how many testers meet the requirements and how many extra entries each one earns. Each eligible tester has 1 entry, plus 1 for each check-in questionnaire submitted within 24 hours (up to 3), plus 1 for the notes bonus: up to 5 entries. Your chance is your entries divided by all eligible entries. If all 20 testers are eligible:
- Everyone earns the same number of entries: a 1 in 20 chance (5%).
- You earn all 5 and everyone else earns only 1: 5 of 24 entries, about 1 in 5 (21%).
- You earn only 1 and everyone else earns all 5: 1 of 96 entries, about 1 in 96 (1%).
- Not affiliated with or sponsored by Rockstar Games, Take-Two Interactive, Sony, Microsoft or Nintendo.
Disqualification
You can't win, and your entries don't count, if you:
- Don't meet the entry requirements: you stop early, uninstall Prove/n or leave the tester program on Google Play, earn minutes on fewer than 10 of the 14 days, or skip a check-in questionnaire.
- Use bots, scripts, AI tools (such as ChatGPT) or anything else automated to answer questions or operate the app for you.
- Run Prove/n on an emulator or anything other than your own real Android phone, or use a modified version of the app.
- Exploit a bug to earn minutes or entries instead of reporting it.
- Register more than once, or use more than one Google or Prove/n account.
- Give false information, such as your age or province, or upload a consent form your parent or guardian didn't sign.
- Pick a level in the app that doesn't match you, such as a university student choosing "High school student".
- Submit random, copied or AI-written check-in answers or bug reports.
- Helped build Prove/n, or live in the same household as someone who did.
If the winner doesn't reply within 7 days of being contacted, or doesn't answer the skill-testing question correctly, a new winner is drawn.
