About

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.
