Hey everyone! 👋
I built an Android app called Engineering Notes to put a large collection of engineering calculators, converters, technical utilities and reference tools into one app.
It currently has 77+ tools, including:
Electrical
- Ohm's Law
- Voltage Divider
- LED Resistor Calculator
- Wire Size & Voltage Drop
- Battery Calculator
Electronics
- 555 Timer
- RC Circuit Calculator
- Logic Gates
- Truth Table Generator
- Boolean Simplifier
Mechanical
- Torque
- Gear Ratio
- Spring Calculator
- Thermal Expansion
Civil
- Concrete
- Brick
- Steel Weight
- Beam calculations
Chemical & Physics
- Molar Mass
- pH
- Gas Laws
- Projectile Motion
- SUVAT
- Waves
- Optics
Programming & Networking
- JSON Formatter
- Base64
- Hash Generator
- UUID
- Regex Tester
- JWT Decoder
- URL Encoder
- QR Generator
- Subnet Calculator
- DNS Lookup
It also includes scientific/statistics/matrix calculators, 20+ unit conversion categories, engineering reference tables, notes with Markdown & tags, and more.
Most tools work offline.
I recently added an AI Engineering Assistant as well, although that feature requires an internet connection.
I'm continuing to improve the app, so I'd really appreciate feedback from anyone who gives it a try.
