    Hi Everyone,

    I have been trying to find a nice simple audio chronograph app for my phone but Chron-lite and Bowometry seem to no longer be available, does anyone know where these apps, or a similar one, can be found?

    Thanks

    I've not yet seen a cell phone app chronograph that as accurate to within 10% of actual speeds.

    I tried the Phyphox app, you can set it to timer and start/stop being sound triggered.
    Holding it near the crossbow and shooting into something hard works for me, although pretty short distance (5m). Might need to compensate for distance by calculating sound delay.
