Plus & Minus - Write by Hand

Addition & subtraction to 20

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Practice addition and subtraction within 20 by writing the answers by hand. No ads, no sign-in — everything stays on the device. Plus & Minus is a practice app for children learning addition and subtraction within 20 by writing the answers by hand. HOW IT WORKS • Make a number / Take away — pick a number from 5 to 19 and solve problems like 3 + □ = 5 and 5 − □ = 2. The blank moves around, so children practice number bonds, not just answers. • Mixed practice — ordinary sums like 2 + 3 = □ with numbers mixed from 5–9, 10–19 or 5–19. • Write the answer in the box with a finger or Apple Pencil. The app reads the handwriting right away and checks it. • Switch between horizontal and vertical (column) layout with one button. • If the app can't read the writing, the box turns yellow so your child can try again. • On first launch, a short guide shows how to write in the answer box. • Fits iPhone, iPad and the unfolded iPhone Duo screen. HISTORY AND STATS • Every session is saved on the device, handwriting included, so you can replay past practice. • Stats show which numbers and which positions need more practice. SAFE FOR KIDS • No ads, no accounts, no subscriptions. • Everything, including handwriting recognition, happens on the device. The app sends nothing to us. • Buying, outside links, erasing history and changing how long it is kept are behind a grown-ups check. FREE AND ONE-TIME PURCHASE • Make a number 5–9, Mixed practice 5–9, the history and the stats are free. • A one-time purchase unlocks numbers 10–19, Mixed practice 10–19 and 5–19, and the 20-problem test. Family Sharing is supported. • Purchases are saved on the device and stay unlocked without internet. Questions: support@innomote.com
