## What is TriProCalc?

TriPro Calc is more than just a calculator — it’s a professional race planning tool built by athletes, for athletes. We combine precision calculations with exceptional usability.

Why TriPro Calc belongs on your phone

4 Calculators in One
TriPro Calc features a central race planning hub (supporting everything up to Double Ironman) plus three fully independent tools for swimming, cycling, and running. Calculate pace and time for full races or individual training sessions.

Built for Everyone (Left-Handed Mode)
We know one-handed usability matters. TriPro Calc is the only app with a dedicated Left-Handed Mode — switch instantly and all controls mirror for your left thumb.

Pro-Level Accuracy
No more awkward seconds. All pace and time calculations are automatically rounded to the nearest 5 seconds — just like professional race planning.

Flexible Systems
Easily switch between kilometers and miles on the main screen, while keeping metric consistency within the individual tools.

History & Sharing
Save your plans as detailed cards with pace and speed data. Share your calculations with your coach or friends via WhatsApp, Telegram, or social media in just one tap.
