Measure projectile velocity with your phone. Balchron times the shot by sound, measures range by GPS and solves muzzle velocity and energy — no chronograph screens to set up or shoot through.

Services
The skills behind our own apps, available for yours: we test software for security weaknesses, and we build websites and applications to order.

About
AlephVec Labs (Pty) Ltd is a South African software company (registration no. 2026/821118/07) building apps that turn the sensors in your phone into practical measurement and calculation tools. More about us.
Measured, not guessed
Our apps are built on real data. Balchron's shot detection is tuned on recordings from actual ranges and validated against tape-measured distances.
Works without signal
Ranges and farms rarely have good coverage. Core features run on the device; anything that needs the internet waits until you're back online.
Privacy first
No advertising, no tracking, no selling data. We collect only what a feature needs and say exactly what that is in each app's privacy policy.
Contact
Questions, bug reports, feature requests or data requests — we read everything.
