Built by two students in Frisco ISD

Your study habits, plotted against what you actually scored.

Insight logs when you study, where, for how long, and on how much sleep, then checks which of it lines up with your grades. All of it is encrypted in your browser, so nobody else can read a word. Not us either.

Free. No password reset, because there is nothing to reset with.

Sleep against test scores

The part that matters

Most of what a tracker would tell you is a coincidence.

Seven habits compared against a term of tests will throw up impressive-looking differences by luck alone. We checked. Driven with generated students, 28 of the 65 findings had no effect built into the data at all , and one arrived with the sign backwards.

So before Insight says anything, it shuffles which of your scores land on which side of the comparison a thousand times, and counts how often chance alone produces a gap that big. Above five percent, you never see it.

Shown

15%

Sessions you started after 11 PM came before lower scores than your own average.

12 sessions, held in 9 of 12

Cleared every gate, and beat the shuffle.

Withheld

+11%

Studying at the library came before higher scores than your own average.

7 sessions so far, not enough to say yet

An eleven-point gap, and still not shown, chance produced one that big in 19% of shuffles. This is the whole idea.

Every statement says came before, never caused, and there are tests that fail the build if that slips. Comparisons are against your own average, never against eight hours, or a study tip off the internet.

How it works

Four things, and three of them happen without you.

  1. 01

    Start the timer

    Subject, where you are, how loud it is. Your Canvas courses are already in the list, so it's three taps.

  2. 02

    Grades arrive on their own

    Canvas syncs every ten minutes. Home Access Center is read through the extension, using the session you're already signed into.

  3. 03

    Two questions a day

    Sleep in the morning, phone time at night, the only two things the app can't measure for itself. Skipped on days you've already answered.

  4. 04

    It waits

    Nothing is claimed until there are enough sessions behind it, it has held across more than one week, and it has beaten a thousand shuffles of your own data.

Encryption

We built it so that we couldn’t read your grades even if we wanted to.

The key never leaves

Your password is stretched through 600,000 rounds in your own browser, and what comes out unlocks your data there. The server is handed ciphertext and nothing else.

So the maths runs on your device

Every pattern on this page is computed in the tab you have open, because the only machine that can read the inputs is yours. That is a consequence, not a feature.

And there is no reset

Forget the password and the data is gone, we cannot recover what we cannot read. Said here rather than in a support article, because it is the price of the two paragraphs above.

Reminders carry no data either, the server can tell that Tuesday night is unlogged without knowing what you would have written. So a lock screen never shows your grades to whoever picks up the phone.

Five ways to log

It counts the time so you don’t have to guess at it.

Install whichever you actually use. Each one counts app and site time in the background, and can block what you name while a session is running, with a three-second override that gets recorded, rather than a hard lock you’d have uninstalled by Thursday.

Browser extension

Chrome

Counts sites, blocks the ones you name, reads your gradebook.

Mac

Swift

Counts app time. Stops counting when the display sleeps.

Windows

C#

Same counting. Closes a blocked app politely, so nothing is lost.

Android

Kotlin

Apps and sites both, the sites through a local DNS filter.

iPhone

Web app

Add to Home Screen. Logging and reminders; no blocking, see below.

Why iPhone can’t block

Apple puts app blocking behind an entitlement that is granted, not bought, and we don’t have it. Rather than pretend, the iPhone app uses a Shortcuts automation you set up yourself.

Downloads and setupNothing is required, the web app logs on its own.

A term of your own data, honestly read.

It takes a few weeks of logging before anything clears the gates. That wait is the point, but you can see what the far end looks like right now.
