BuffCat: Strength Training Log

Finish a workout and Buff Cat flexes the muscles you trained. Muscle recovery, routines, supersets, automatic PR tracking and Apple Watch, all in one app.

Every set counts. Your cat shows it. BuffCat turns your strength training into a 3D cat that changes with every workout. Log your sets, track recovery and see your progress. No account. No ads.

■ A cat built by your workouts • The muscles you train show up on your 3D Buff Cat. • Buff Cat strikes a bodybuilding pose to show off your most-trained muscles. • Once your muscles recover, Just Cat returns to rest on all fours. • Work out again and watch it transform back into Buff Cat.

■ Finish with a flex • After your workout, Buff Cat stars in a highlight scene. • Your results card shows volume, workout time, total sets and new PRs. • Save or share Today's Buff Cat as a vertical image.

■ Know what's recovered • See each muscle's fatigue on your 3D cat and on front and back muscle maps. • Check your recovery for now, tomorrow and the day after. • See at a glance which body parts are ready to train.
