Analyzes gear ratios on a bicycle based on chainrings and cassette cogs.

Calculates power, pace, or calories based on performance on a rowing machine (ergometer).

Estimates hiking time or calories burned based on distance, elevation gain, and pace.

Calculates the Kill/Death ratio, a common performance metric in video games.

Calculates target split times for different segments of a race or run based on overall goal time.

Calculates cycling power training zones based on your Functional Threshold Power (FTP).

Calculates the Forward of Center (FOC) balance point for an arrow, which is crucial for archery accuracy. FOC is expressed as a percentage of the arrow's total length.

Estimates nutritional needs (calories, fluids, electrolytes) during triathlon training or racing.

Estimates calories burned while running, based on distance/time, pace, and weight.
