Nimoh® Ballistics Pro, has no in-app purchases, which means you get all the reticles for free once purchased, as compared to the Ballistics (free) edition where the reticles are in-app purchases.

Nimoh® Ballistics Pro also adds some extra value functionality, in that it can connect to a Bluetooth weather meter to automatically record in real time, wind speed and wind direction! (Kestrel 5XXX Bluetooth series support only - more coming soon).
