Log each session and the plan it belongs to — two separate views that stay reconciled through every workout. Strength, cardio and HIIT, tracked privately on your device.
SmartFit is a private fitness tracker that separates what a session is — strength, cardio, HIIT or mobility — from the recurring plan it belongs to. It supports 4 proven training strategies: Push/Pull/Legs, Upper/Lower, Full Body 3× and Cardio & Conditioning. SmartFit never pairs with a watch or ring; you log sessions manually so nothing is misattributed. Your data lives entirely on your device — there is no account and no cloud watching you.
SmartFit is a free private fitness tracker built for consistency — it keeps your activity types separate from your recurring plan and reconciles them automatically.
Every logged session is tagged to an activity type — strength, cardio, HIIT, mobility — so the workout stays separate from the plan behind it.
