It is a tool you build with, not a note-taker.

🔧 WHAT YOU CAN DO
⚙️ Studio — dial in a module and two tooth counts and watch a real meshing pair turn. Every change re-solves instantly: ratio 📊 centre distance 📏 and an undercut warning ⚠️ if the pinion has too few teeth.
🔗 Gear train — chain several gears together, edit each gear's tooth count and read the speed 🚀 of every gear plus the total reduction and output direction 🧭
🦷 Tooth profile — see a single tooth drawn as the true involute of its base circle, with the base, pitch and addendum circles overlaid.
🧮 Ratio solver — enter a target ratio and get the best tooth-count pairs ranked by accuracy 🎯 ready to use.
💪 Torque & speed — watch speed decrease while torque increases, with a safe tooth-load check ✅
⚙️ Mechanisms — explore live planetary sets 🌍 worm drives 🪱 rack & pinion ↔️ and bevel gears, each with the maths behind it.
🖼️ Spec card — place your build on your own photo 📸 and save a clean specification card to your gallery.
📂 History & Bench — save your builds 💾 and compare any two side by side.

👨‍🔧 DESIGNED FOR
🖨️ Makers, 3D-printing hobbyists, 🤖 robotics enthusiasts 🎓 engineering students and anyone curious about how gears really work.

✨ BUILT RIGHT
🔒 Core design tools work fully offline — no account, no sign-up.
⚙️ Real involute geometry and gear kinematics, not decorative cogs.
🌙 A clean, focused dark interface with smooth animations.

Luccky TigerX turns the mathematics of gears into something you can see, explore and understand. ## Rankings - #702,923 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_ADSERVICES_AD_ID` - `android.permission.ACCESS_ADSERVICES_ATTRIBUTION` - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.CAMERA` - `android.permission.INTERNET` - `android.permission.POST_NOTIFICATIONS` - `android.permission.WAKE_LOCK` - `com.aifactory.directi.pro.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` - `com.android.vending.CHECK_LICENSE` - `com.google.android.c2dm.permission.RECEIVE` - `com.google.android.finsky.permission.BIND_GET_INSTALL_REFERRER_SERVICE` - `com.google.android.gms.permission.AD_ID` ## Similar extensions and apps - [GearDesignWizard](https://chrome-stats.com/d/com.embarcadero.gdw01) — 15 users - [Engineering Design AI Agent](https://chrome-stats.com/d/com.manojky.GearIonicPro) — 140 users - [Gear Design 3D in TrueGeometry](https://chrome-stats.com/d/com.ionicframework.gear225190) — 29,966 users, 3.50 / 5 - [Gears](https://chrome-stats.com/d/mengineeringtech.me.gears) — 1,992 users - [Gear train](https://chrome-stats.com/d/com.gear_check_tab) — 1 users - [CLrotatingGear](https://chrome-stats.com/d/com.clrotatinggear.gearcl) — 722 users - [Machine Utilities](https://chrome-stats.com/d/com.aavishkruti.utilities) — 49 users - [RotateGear](https://chrome-stats.com/d/com.gearpuzzle.rotatecsface) - [Mechanical Engineering Gears](https://chrome-stats.com/d/com.kadrala.sreejith.gears) — 49,827 users, 3.29 / 5 - [LatheGearPro](https://chrome-stats.com/d/com.lathegearpro.gearwizard) — 22 users - [Gear Rotation Lab](https://chrome-stats.com/d/com.gearlab.rotation) — 7 users - [GearMaster V2 DEMO](https://chrome-stats.com/d/com.xway.gearmasterv2.demo) — 150 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.aifactory.directi.pro)
