Ballista - Ballistic Calculator

Ballista is a ballistic calculator for Garmin devices. It supports G1 and G7 ballistic coefficients, displays windage and elevation calculation results as MIL or MOA, stores 10 user editable ballistic profiles, and includes a preset range calculation card. Ballistic calculations include compensation for Coriolis effect based on the user's GPS position and account for spin drift based on user-set barrel twist rate and zero range. Realtime barometric pressure and altitude sensors take priority as inputs, while temperature input from current weather is used to provide the most accurate ballistic solution. The user can enter and calculate ballistic solutions down to one meter or yard of range and 0.1 mph or kph for wind inputs by holding the UP button for fine adjustments. Controls: START/STOP (Tap): Cycles user input between Profile, Wind Speed, Range, and MIL/MOA START/STOP (Hold): Opens the preset range card UP/DOWN (Tap): Changes the currently selected input in a large step increment (25 for range, 0.5 for wind) or changes selected profile or MIL/MOA UP (Hold): Scrolls the selected input up by a small increment (1 for range, 0.1 for wind) for as long as the UP button is being held Ballistic profiles, metric/imperial unit preferences, and preset ranges can be edited through the Connect IQ phone app under app settings for Ballista.

1.3.0: Add spin drift and Coriolis effect to ballistic calculations 1.2.2: Settings update 1.2.1: Update temperature sensor priority to avoid skin temperature influence 1.2.0: Add preset range card functionality 1.1.0: Add fine adjustment of range and wind by holding UP button (+1 for range, +0.1 for wind)
