The FITR Client App includes three built-in calculators accessible from the Log Performance screen — Rep Converter, Percentage Calculator, and Pace Calculator. They are also available on the FITR website.

Open the FITR Client App, go to the Log Performance screen for any training section, and scroll to the Calculators section.

Enter a weight and rep count you know, and the calculator estimates what you could lift for any rep range from 1 to 20.

Example: Input 100kg for 1 rep → estimated weight for 8 reps = 81kg.

Enter any number (e.g. your 1RM, max time, or distance) and the calculator displays a table of values from 2.5% to 100% in 2.5% increments.

Example: Input 200 → 80% = 160, 50% = 100, 20% = 40.

Enter a pace per km or mile and the calculator shows estimated finish times for common race distances (5km, 10km, half marathon, marathon, and more). For each distance you get three results: your entered pace, 5 seconds faster, and 5 seconds slower.

Example: Input 05:00 pace → 5km times: 24:35 / 25:00 / 25:25.
