Jotrix

Jotrix is a smart productivity app that combines a powerful notebook with multiple calculators in one place. Write and organize your notes, pin important ones, color-code them, and search everything instantly. Use the basic calculator for everyday math, the scientific calculator for advanced operations, and the unique text calculator where you can write math naturally like writing notes. Convert units across length, weight, temperature, volume, speed, and more with a single tap. Every calculation is automatically saved to your history so you never lose a result. All your notes and history are stored completely offline on your device — no account needed, no internet required, no data shared. Jotrix is built for students, professionals, and anyone who thinks and calculates at the same time.
