Kaleidoscope
Read full descriptionHide full description
Kaleidoscope is a drawing toy. You scribble and every stroke gets mirrored across a set of rotated axes, so a few lazy lines fall out as a full symmetric mandala. Change how many ways the canvas folds, switch between true mirror symmetry and plain rotation, pick colors or let them run through a spectrum, and draw with your finger or an Apple Pencil — it feels the pressure. Drawing and downloading are free, no account. Sign in and you can save a piece to the gallery, where it gets its own link, browse what other people have made, and open someone else's to keep drawing on top of it. When you save, it'll suggest a name for the piece if you want one. It's the same gallery as kaleidoscope.ponderance.dev, so anything you make here shows up there, and the other way around. No ads. It collects nothing while you draw. Make something symmetric and see where it goes. Update 1.1 is accessibility, the whole app. VoiceOver works everywhere now, including the canvas itself, so you can draw without seeing the screen and hear each stroke land. Every piece in the gallery gets a spoken description of what it actually looks like, from the same model that suggests names when you save. Text scales as big as you need. Animations calm down when your phone asks them to, and the colors finally have names instead of hex codes. If something still doesn't work the way you need it to, tell me and I'll fix it.

Verdict
The clearest difference is in-app purchases: Kaleidoscope at none against HyperRef's 1. On price, ads, device support and iOS requirement there is nothing between them.
