## Description

Forget manual formulas and spreadsheet errors—get precise radioactive activity calculations instantly.

DecayMate is a dedicated physics utility designed for laboratory reference and research. It streamlines the complex mathematics of radioactive decay, allowing you to focus on your inventory and calculations without the guesswork.

KEY FEATURES:

• Decay Calculator: Perform forward-decay calculations instantly. Input a starting activity and calculate exactly what remains after minutes, hours, or days based on standard exponential decay laws.

• Target Activity Planner: Need a specific activity level at a future time? Use the backward-calculation tool to determine exactly the initial activity required to reach your target based on the isotope's half-life.

• Live Tracker: Pin an active source and monitor its decay in real-time. Watch the activity decrease second-by-second on the live dashboard or via Home Screen widgets.

• Custom Library: Comes pre-loaded with standard isotopes (Tc-99m, F-18, I-131, Cs-137, etc.). Need a specific radionuclide? Create and save custom isotopes with your own precise half-life definitions.

• Unit Converter: Seamlessly toggle calculations between Curies (mCi, Ci) and Becquerels (MBq, GBq) anywhere in the application.

• Privacy First: DecayMate operates entirely offline. Your custom isotope data and calculations are processed locally on your device and are never transmitted to the cloud.
