Electric Mods opens the whole catalog — 500+ real vinyl wraps and PPF finishes from the manufacturers your installer already buys from, every one rendered accurately on your car. Browse by color. Compare finishes. Find the satin you didn't know existed, the color shift nobody in your area is running, the exact PPF that matches what you saw last week. Then add the rest, wheels, body kit, tint, lowered suspension, and see the whole build come together before you commit to any of it. WHAT'S INSIDE: • 500+ real wraps and PPF finishes, by name • Wheels, body kits, spoilers, diffusers(select models) • Suspension lowering simulation • Window tint control by percentage • Interior customization(select vehicles) • Daylight, shade, and night lighting • Community build gallery • Send builds to shops for quotes Works with Tesla Model 3, Model Y and more EVs.

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. If you have feedback, ideas, or just want to share what you made — focused.era1@gmail.com. Now go make something.
