InterestOS turns what your child already loves — dinosaurs, soccer, space, horses — into personalized lessons they’ll actually want to sit down for. Fill them in right on your iPhone or iPad, or print them out. Tell us your child’s name, grade, and a few interests. InterestOS picks an official grade-level standard and writes a complete learning pack around it in seconds: • A STORY starring their interests, written at their reading level • A WORKSHEET on a real K–5 skill, aligned to official standards — tap it in or print it • A PARENT GUIDE so you can teach it in a few minutes — no prep • Original, kid-friendly artwork you can print in color, black & white, or as a coloring page PRINT IT, OR TAP IT IN Every worksheet can be printed — or completed right on your iPhone or iPad. Your child taps and types their answers and each one checks itself instantly, with gentle encouragement instead of red X's. When they finish, you see exactly what they answered and what they missed. It all happens on the device: no internet, no AI, nothing about your child sent anywhere. Every pack is built on real academic standards — the full Common Core (Reading, Writing, Math, Language), the Next Generation Science Standards, and California History–Social Science. You choose the subject and skill; we handle the rest. WHY PARENTS LOVE IT • Personalized to your child, not a generic worksheet • Hand over the iPad, or print at home and go — the couch, the kitchen table, the car • Follows your child’s grade, from Kindergarten through 5th • A simple “journey” view tracks skills practiced and completed PARENT-FIRST AND PRIVATE BY DESIGN • No child login and no child chat — a parent runs everything • We only use a first name/nickname, grade, reading level, and interests to make a pack. Never an address, school, birthday, or photos. • Brand-name interests are converted to safe, generic themes before anything is generated, so packs stay original and age-appropriate.

Make as many learning packs as your child wants — there's no monthly limit anymore, and the price is now $6.99/month. Printing, layout edits, and fixing a pack are still always free. Packs arrive faster, too. And the artwork now illustrates a moment from your child's story, or the real thing the lesson is about, instead of a generic classroom scene. Also in this update: clearer "Words to Know" definitions and a few worksheet formatting fixes. ### 1.1.2 — 2026-08-26 Two changes, both from parent feedback. BROWSE EVERY SKILL FOR THEIR GRADE When you create a pack, "Other Skills for This Grade" now shows every skill for your child's grade and subject — not just the first few. Fractions, measurement, geometry and the rest are all one tap away, grouped by topic so a long list stays easy to scan. A BIGGER PRINT SIZE Edit Layout has a new X-Large text size, for kids who need more room to write. It makes the printed text bigger and the answer lines wider at the same time. As always: print a pack for the kitchen table, or hand over the iPhone or iPad and let your child tap the answers in. ### 1.1.1 — 2026-08-11 A few small refinements this update to make InterestOS easier to find and use. Nothing new to learn — every pack still works exactly the same: read the story, then fill in the worksheet right on the iPhone or iPad, or print it out and go the paper route. Whichever your family prefers. ### 1.1.0 — 2026-08-07 Worksheets can now be completed right in the app. Your child taps or types their answers on the iPhone or iPad, and each one checks itself instantly. There are no red X's — a miss just says "not quite, try again," and after two tries it shows the answer so nobody gets stuck. Everything still prints exactly as it did before, so you can pick paper or screen for any pack. Also in this update: • Read the story again — the story is one tap away while your child works, so they can go back to the part a question is about. • See how they did — when they finish, the worksheet shows you exactly what they answered, what they missed, and the correct answer, so you don't have to hunt through the answer key. • More practice on screen — reading, writing, science and social studies packs now include extra quick practice when you fill them in on the device. The printed page stays exactly as short as it was. • Fixed: the story picture sometimes kept showing the placeholder illustration even after you generated a new one. It now updates right away, and if a picture genuinely fails to draw it says so instead of quietly showing the generic art. Practice happens entirely on your device — no internet, no AI, and nothing about your child is sent anywhere. ### 1.0.1 — 2026-07-30 A fresh new look — meet our new app icon!
