Tennis Custom

Customize your racquet with real precision.
Weight, balance, swingweight, and twistweight — all in the palm of your hand.
Tennis Custom was built for players who want real precision when customizing their racquets.
Powered by a physics-based mass distribution model, the app calculates exactly how every adjustment affects your racquet — including power, control, stability, and spin. It also shows the real trade-offs: more stability usually means a heavier feel during the swing, and Tennis Custom gives you the exact numbers behind every change.
