It works the six days you're not there.
This is not trying to replace you
There is no teaching here, no curriculum, and no diagnostic telling a family what to work on. It sends one question a day and explains the answer. Everything that requires judgement is the part we do not do: what to prioritise, why a mistake keeps happening, what to do about pacing.
You see a student once a week. The other six days are where retention is won or lost, and right now you have no presence in them. That's the gap this fills.
It doesn't compete for the same slot
Khan, UWorld, a practice book, your own problem sets. None of it conflicts. Those are sit-down work, an hour at a desk that has to be scheduled. This is ninety seconds on a phone that is not scheduled at all. A student who does both has done both.
If a week gets busy and the questions go unanswered, nothing is broken or lost and the next one still arrives. Missed questions and their explanations can be retrieved from their private link any time while it is open, which is up to 30 days after test day.
Walk in already knowing what they got wrong
A student can share a results page with you: every question they've been sent, what they answered, and the worked explanation. It opens in a browser with no account, no login and nothing to install, and it carries no name, phone number or email.
The student sends it to you. You can't request it or look it up, and there's no tutor account behind it. It is a link they choose to share, per test. They can replace it at any time, which cuts off the old one. It closes 30 days after test day.
What a family pays
$14.99, once, for the run up to their test date. It is not a subscription and it never auto-renews. That covers up to five months of daily questions; a test closer than 30 days out costs less, and a longer run costs a little more, so /pricing is the figure to send them to rather than one quoted here.
If it's useful, send it to a family
What you send is the page written for parents, not this one.
Passing it on to a family
Nothing to sign up for, and nothing that identifies you. Send the link or paste the note — whichever fits how you talk to families.
https://textprep.org/for-parentsOne SAT question a day, by text — no app, no login, it just shows up on their phone. It's a one-time cost, not a subscription. Worth a look: https://textprep.org/for-parents
