How to reach me
Email: support@mathkatas.com
I am one person. I built the app, and I answer the support email. Most questions get a reply within a day or two.
Free promo codes
I have a small number of free App Store promo codes set aside for parents whose kid is failing the multiplication timed test and who'll commit to one Kata a day for a week. If you'll do the protocol, email me with a sentence or two about your situation and I'll send you a code.
Common questions
How long does the protocol take?
One Kata per day, every day, for seven days. About fifteen to twenty minutes per session. Total study time across the week is usually two to three hours. Read why daily, not weekly before you start.
My kid says they're "stuck on the 7s." Can we just practice that row?
No, and the reason is the most counter-intuitive thing on this site. See why the whole Kata.
Does the app work on Android?
Not yet. An Android version is in development. The current app runs on iPad and iPhone. If you don't have an Apple device, hang tight — Android is coming.
Does the app work for older or younger kids?
The app teaches the multiplication table, which is roughly a fourth-grade-level skill in the U.S. It works just as well for older kids who never quite locked in the table, and for younger kids who are accelerating. There's no age requirement built into the app.
Will it work for my specific kid?
I don't know, and I'm careful not to overpromise. The protocol worked for my nephew Scotty in 2009, and it worked for the kids I observed in classrooms over thirteen years. There are kids it won't work for, and I'm not in a position to predict which kids those are. The honest version is on the founder's note page: try it for a week, and if it doesn't fit, you've spent a week and learned this approach isn't right for your kid.
What if my kid finishes a Kata in five minutes?
That means they're getting fast — which is the goal. Don't add more sessions in the same day; that breaks the daily-rhythm logic of the protocol. Just keep doing one Kata a day until the week is up.
What if my kid takes 45 minutes the first time?
Normal. Scotty's first Kata took forty minutes. By day three he was under fifteen. The protocol is engineered around exactly this curve.
iCloud sync isn't working.
Make sure iCloud is enabled for Math Katas in iOS Settings → Apple ID → iCloud → iCloud Drive → Math Katas. Sync requires a network connection on both devices and may take a few minutes after a session ends. If it still isn't working after a few minutes, send me an email with the device model and iOS version you're on.
I found a bug.
Email me. Include the iOS version, device model (iPad / iPhone model), and a description of what you were doing when the bug happened. A screenshot or screen recording helps.
I have a feature request.
Send it. I read every one. The app's roadmap is shaped by what real parents and teachers ask for.
I'm a teacher and want to use this with my class.
Email me. I'm happy to talk about classroom use, ClassKit integration, and bulk promo codes for school deployments.
What's next
If you haven't already, the daily-vs-weekly warning is the single most important thing on this site. The eight rules are the second.
