Motecraft
Read full descriptionHide full description
Motecraft is a quiet little gallery of small visual worlds. Tap a card and you're inside. Long-press to pour embers into a mandala. Drag a curtain of aurora light. Watch a flock of geese lock into a V and follow your finger. Throw a Spider firecracker that walks legs across the sky. Look at a Cymatics Mandala blooming from a single tone. Hundreds of them, all hand-built — and growing. FREE FOREVER, PLUS PRO The original collection stays free forever. Every visual you could open before, you still can — no account, no catch, nothing walled off after the fact. Motecraft Pro unlocks a growing collection of new premium worlds — the richer, shader-grade pieces — and helps keep this one-person studio building. That's the whole deal: the free gallery stays free, Pro adds the new stuff on top. WHAT MAKES MOTECRAFT DIFFERENT — No accounts to use it. Open the app and you're in. — No ads. None now. None planned. — No tracking. Standard Apple-style crash and performance data, nothing else. — The free collection is free forever — not a trial. THE CATEGORIES • Mandala — radial geometry that responds to your hand. • Aurora — silk curtains, slow ribbons, braided light. • Swarm — flocks, schools, formations that follow you. • Firecracker — taps that burst into walks across the sky. • Fractal — Mandelbrot, Julia, Burning Ship. • Crystal — slow growth that fills the screen. • Fluid — gradient fields you push around. • Snow, rain, smoke, sand — the small physical things. • Henna & calligraphy — symmetric ink that you draw. • Candle, lantern, fireflies — quiet ambient lights. HOW IT FEELS TO USE Designed for moments, not sessions. Open it for two minutes between meetings, before bed, on the train. Pick a card, watch it become, put the phone down. Then come back tomorrow and pick a different one. Each experience runs natively on your hardware at full frame rate. No external dependencies, no servers in the loop, no spinners. New visuals arrive from time to time — they just appear. MOTECRAFT PRO One unlock, every premium world — now and everything added later. • Lifetime — pay once, keep it forever. (Best value.) • Annual — with a free trial to start. • Monthly — for a lighter commitment. Sign in with Apple or email — only so your unlock follows you across your iPhone and iPad. You still never need an account to enjoy the free gallery. PRIVACY, IN PLAIN ENGLISH We collect anonymous crash reports and performance metrics through Firebase. That's it. No advertising ID.

A NOTE FROM THE MAKER Motecraft Studio is a one-person studio in Ahmedabad, India. I write the code, draw the visuals, design the cards. Made on long evenings, on weekends, between consulting work. Pro is how you keep it going — and how the premium worlds keep coming. If something is broken or you want to see a particular visual added, write to me directly. Feedback, requests, complaints → support@motecraftstudio.com Made with care, for moments. — Payment is charged to your Apple Account.

Verdict
The clearest difference is ads: Motecraft at none against Krun's shown. Krun's advantage is update cadence (every 3 days vs every 2 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
