Learn to draw one stroke at a time. When a part goes wrong, let the AI fix just that part. AI FIX House came out crooked? Can't draw hands or a face in profile? Circle that part and the AI redraws it in your own style. Nothing outside the circle changes. It works on drawings you make here and on any picture from Photos. Circle an empty spot and say what to add, and it draws that in your style too. Hold to compare before and after, then keep it, save it or share it. Two fixes are included; packs of 10 and 50 are sold separately, no subscription. Images are uploaded only when you choose AI Fix; see Privacy below for processing and retention details. AI Fix is not available in the mainland China App Store. LESSONS, ONE STROKE AT A TIME • A dashed guide shows the next stroke: where it goes and how big. • Draw over it with your finger or Apple Pencil. Every stroke is checked for shape, position and size. Redo it, or keep it and move on. • A kept stroke settles onto the guide, and the line still looks like yours. Switch this off in Settings if you prefer. • At the end, your lines appear beside the corrected drawing with a similarity score. • Then the guide goes away and you draw the same subject from memory. 233 DRAWINGS 114 are included: the whole Easy level, 110 drawings of 1 to 12 strokes across animals, food, nature, everyday objects and vehicles, plus four harder samples such as The Great Wave and Girl with a Pearl Earring. The Advanced Set unlocks the other 119 Medium and Hard drawings, up to 121 strokes: anime characters, chibi animals, scenes such as a torii gate in the water, a castle and a Ferris wheel, plus the Mona Lisa and The Scream as simple line art. One-time purchase, no subscription. Future advanced drawings are included, and the purchase restores on your other devices. ALSO INSIDE • Search drawings by name or category, alongside the difficulty filter. • Doodle Challenge: draw a named subject from memory in 20 seconds and see whether the app recognizes it. • A gallery of your last 500 drawings, shareable as images. • Progress for every drawing, a difficulty filter, pinch-to-zoom, and "skip this stroke" so a lesson never gets stuck. • An optional daily reminder, and Apple Pencil double-tap to undo. • Made for iPhone and iPad. PRIVACY No account, no ads, no tracking. Lessons, progress and your gallery are stored on your device. Purchases use Apple’s StoreKit.

Wertequadrat's advantage is in-app purchases (none vs 3) and iOS requirement (13.0 vs 17.0). On ads and device support there is nothing between them.
