JournalGrading
A grade you can talk yourself into is worth nothing. How Simplify1 keeps the letter honest, and why a solid B is good news.
Most habit apps are built to make you feel good. Counters that only go up, badges for opening the app, a burst of celebration for a day that was, honestly, half done. It feels nice for a week. Then it stops meaning anything, because you know the number would have said the same thing whatever you did.
Simplify1 was built the other way round. The grade is meant to be something you can trust, and that means it has to be something you cannot talk your way into.
Every item on your list carries base points, most between 25 and 200, and a weight you can see: Low, Medium, High or Critical. The weight multiplies the points. Low counts once, Medium twice, High three times, Critical four times.
At the end of the day Simplify1 adds up the points you earned and divides them by the points that were possible. That percentage becomes a letter: 97% and up is an A+, 93% an A, 90% an A-, 87% a B+, 83% a B, and the scale keeps going below that, all the way down. There is no curve and no bonus for a long streak. Grade the same day twice and you get the same letter.
The weights are what keep the letter honest. If every item counted the same, you could fill a list with easy wins, tick them all, skip the one thing that actually mattered, and still look great. With weights, a missed Critical item costs four times what a missed Low item does. Ten glasses of water do not make up for skipping the thing you said was most important.
That is also why the rubric is yours. Two people can have the identical day and get different letters, because they told the app different things matter. Neither grade is wrong. Each one is honest about its owner's priorities.
A B means at least 83% of what you said mattered got done. That is a good day. It usually means the important things happened and something smaller slid, and the letter says exactly that. Open the grade and you see which items earned their points and which didn't, beside the count of items done, so the letter is never a mystery.
An A+ earned by quietly lowering the bar tells you nothing. A B earned with the bar where you set it tells you where you stand and what tomorrow's one improvement is. Over weeks, a run of honest Bs is the record of someone who keeps showing up. That is worth more than any badge.
Here is the part people don't expect. When you open Simplify1 in the morning, the ring already says A+. Nothing has been missed yet, so every point is still available. The ring shows the grade you are on track for, and it only comes down when points stop being available: when you answer No to an item, or when the day ends with something left untouched.
So the question the app asks all day is not "how much have you done?" It is "are you still on track for what you said matters?"
Honest does not mean punishing. A missed item is information, not a verdict on you. You can take one day off in any seven, declared on the day before you have logged anything, and nothing is graded that day. Your streak counts any day you complete at least one item. And changing a weight doesn't rewrite saved grades: yesterday stays what it was.
What the app won't do is pretend. If the day was a B, it says B. If it was lower, it says that too, plainly, and tomorrow starts at A+ again.
You can feel how this works in about thirty seconds. The sample day on our home page starts with everything checked. Untick one item, change a weight, and watch the letter move. Then read how weights work, with the arithmetic laid out.

Low, Medium, High, Critical. One worked example shows how the same missed item can cost a little or a lot.
