Prop your phone up and study. Kept counts the time you were actually at the desk โ€” and hands it back as a 15-second video you can post. HOW IT WORKS 1. Type in what you're working on, or don't. 2. Prop the phone up and point the front camera at your chair. 3. Tap Lock in, and study. 4. When you stop, you get your score, a ring showing exactly where the hours broke, and a timelapse with all of it burned in. WHAT THE RING SHOWS The ring is the session. Amber is time you were at the desk. The gaps are where you left. A notch is where you picked the phone up. Every session comes out as a full circle, whether it ran 25 minutes or four hours โ€” the number in the middle is the part that changes. THE CAMERA NEVER LEAVES YOUR PHONE Every frame is analyzed on the device itself. Nothing is uploaded, nothing is kept on a server, and there is no account to create. Faces in the exported video are blurred automatically, and that is on by default. NO CAMERA? USE THE SIMPLE TIMER The Simple Timer is a plain study timer with no camera and no score. It does not make a video. It is free, and there is no limit on it. WHAT'S FREE Kept is free to use. On the free plan you get two scored sessions a week, and your videos carry a KEPT.STUDY watermark. Free clips can be shared the day you make them; keeping them is part of Kept Pro. KEPT PRO Kept Pro takes the KEPT.STUDY watermark off your videos and opens up the rest of the app. โ€ข Yearly โ€” $44.99 per year, after a 7-day free trial โ€ข Monthly โ€” $7.99 per month, no free trial Payment is charged to your Apple Account when you confirm the purchase. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours before the period ends. You can manage your subscription and turn off auto-renew in your Apple Account settings after purchase. If you buy a subscription during a free trial, the unused part of that trial is forfeited. FOR PARENTS Kept is a study timer. The camera does one job: it tells whether the student is sitting at the desk. All of that happens on the phone. No video, image or frame is ever uploaded, there is no account, no messaging and no feed. Faces are blurred automatically in anything the app exports. That blur is on by default; it can be turned off in the app. IF YOU ARE ASKED TO APPROVE A PURCHASE Kept Pro is the same study timer. It removes the KEPT.STUDY watermark, lifts the two-scored-sessions-a-week limit, and lets clips be kept on the phone instead of clearing at the end of the day. It does not add an account, a feed, messaging or uploads โ€” where the video goes does not change. You can cancel any time in your Apple Account settings.

Stop estimating how much you studied. Studial is a measuring instrument for study time: every 30 seconds it checks that you are really at your desk, and only what passes that check is counted. A stopwatch has to believe you. An instrument checks. HOW IT MEASURES Every 30 seconds one interval is judged. In net study mode the front camera takes a brief look to confirm you are at your desk. In focus mode no camera is used at all and only the time your phone was left alone is counted. Each interval gets exactly one verdict - at desk, focus, away, phone, drowsy or not measured - and the session is the sum of them. JUDGED ON YOUR PHONE, THEN GONE A camera check is judged on your phone and discarded in the same instant. No video, no image, no body position is ever stored. Only the verdict survives. There is no account and no server, so your records stay on this phone. WHAT YOU SEE WHEN YOU STOP Net time out of total time, your net share as a percentage, and a timeline of the session showing exactly where you left and where the phone came up. Not a single number on that screen was typed in by hand. PLAN THE DAY IN BLOCKS Lay the day out as time blocks and give each one a subject. A second lane runs beside it, drawn from what was actually measured, so the plan and the reality sit on the same clock. Move a plan and the record stays where it happened. ROUTINES A routine is a weekday template. Set it once and your recurring blocks are laid out weeks ahead. SUBJECTS Tag a session with a subject, give it a colour, and the share per subject tells you where the hours actually went. YOUR PROGRESS, IN PLAIN SIGHT Six axes - time, rhythm, quality, plan, subjects and records - and every one of them is built from measured sessions alone. Watch your net share climb week after week. Find out which subject has been taking far more of your day than you thought. This is not a diary of what you meant to do. It is the evidence of what you did. THE DAY STARTS AT 4 IN THE MORNING Study that runs past midnight belongs to the day it started, so an all-nighter is never cut in half by the calendar. DROWSINESS IS OPTIONAL Off by default. Turned on, Studial looks only at whether your eyes are shut or your head is down on the desk, and stores neither. BACKUP Your records, plans, routines and subjects go into one file, and come back from it. Free for everyone. Measuring, planning, insights and backup are free for everyone, and no feature is locked. One purchase removes the ads. There is no subscription.
