About

Constraint Engine

Read full description

Stop thinking. Start creating. Constraint Engine is the antidote to the blank page. Pick your craft, hit generate, get a sharp one-sentence constraint, start the timer, and make something. No infinite scrolling, no "what should I do today" spiral — just a specific creative restriction and a clock. The science is older than the app: constraints unlock creativity. Limit your palette, your time, your tools, and your brain stops searching and starts making. Every great song, film, and design came from someone working inside a box. Constraint Engine builds you the box. — BUILT FOR 10 CRAFTS — Music (producer / beatmaker) · Songwriter · Writer · Visual Art · Photography · Filmmaking · Game Dev · Developer · Content Creator · Cook. Every constraint is tailored to your craft's vocabulary, tools, and formats — nothing generic. — FREE — • Hand-curated constraints across all 10 crafts • Time-boxed session timer (5 min to a full weekend) • 3 difficulty tiers — Easy, Medium, Hard • Daily challenge — one shared constraint a day for the whole app • XP, levels, streaks, badges — built to make showing up feel good • Save your favorites, replay them whenever • Beautifully designed share card for every session (Instagram, TikTok, iMessage) — no watermarks • Fully usable without an account, email, or any personal data — PRO (AI GHOST-WRITER MODE) — Upgrade to Pro and your constraints are written live by AI in the voice of someone who actually works in your lane: • Genre & style selection (Music, Songwriter, Visual Art) • Vibe picker (Mood + Sound Focus for Music; Tone + Theme for Songwriter) — pick up to 3 descriptors and the AI uses real producer / writer vocabulary, not generic "music words" • A fresh, AI-written DAILY CHALLENGE every day — never the same twice • "Chaos Mode" — bolder, rule-breaking variants of any constraint • Cross-craft chaos chains — finish a song, get the AI to write you the music video shoot ideas to match • "Save to Collection" your best AI constraints, replay them any time — PRIVACY-FIRST — • No account required. No email, no sign-up, ever. • No analytics SDKs. No ad networks. No tracking. • Your XP, streaks, history, name, and avatar live only on your device. • Apple handles all subscription billing — we never see your payment info. • Full policy: see Privacy Policy link in App Store. — SUBSCRIPTION — Constraint Engine Pro is an auto-renewable subscription via Apple. Choose monthly or annual (annual saves you 50%). Cancel anytime in your Apple ID subscription settings. Pro unlocks the AI features above; the free tier remains fully functional forever. — FROM THE MAKER — Constraint Engine is built by an indie developer who got tired of staring at a blank screen and decided to engineer his way out of it.
