What is SmartFit?
The free workout tracker.

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.

Track it by plan or session.

SmartFit is a free private fitness tracker built for consistency — it keeps your activity types separate from your recurring plan and reconciles them automatically.

01

Know what it is

Every logged session is tagged to an activity type — strength, cardio, HIIT, mobility — so the workout stays separate from the plan behind it.

02

Pick a style that fits you

Choose from four proven training strategies. SmartFit lays out your weekly split automatically — push/pull/legs, upper/lower, full body or cardio focus.

03

See it all reconcile

Volume, calories, distance and streaks reconcile across every view. Logged sessions update your plan, goals and trends together — nothing drifts.

Private by default

Local mode keeps your log in this browser; account mode syncs it to your own protected cloud account. Delete a session and its effect reverses cleanly. Export or erase everything from Profile.

Short, practical guides from the SmartFit team — built around the one idea that matters: keep your sessions honest and your plan clear.

Training Foundations4 min read

Why “what you did” and “your plan” are two different questions

Most training frustration comes from mixing a one-off session with the recurring split it belongs to. Keep them separate and progress becomes measurable.

Frequently asked questions

Learn more: activity types · 4 training styles · training guides

Is SmartFit free?

Yes — the full training core is free forever: unlimited workout logging, plans, goals, streaks, records, achievements and data export. The Pro surface is currently a local product preview only; there is no paid subscription or charge in this release.

What does SmartFit Pro add?

The app contains a Pro preview so the planned premium surfaces can be reviewed, but it is not a purchasable tier yet. Paid entitlements, trials and billing will return only after server-side provisioning, cancellation and restore flows are complete.

Is my data still private on Pro?

The current release has no paid Pro accounts. In the local preview, the planned calculations use the same on-device data model; any future paid release must document its billing and entitlement behavior before launch.

Do I need a smartwatch or wearable?

No. SmartFit never pairs with a watch, ring or phone sensor. You log sessions manually, so nothing is misattributed — you decide exactly what counts as a workout.

What training styles does SmartFit support?

Four proven strategies: Push/Pull/Legs (6-day), Upper/Lower (4-day), Full Body 3× for beginners and busy schedules, and Cardio & Conditioning. You can switch plans anytime without losing history.

What activities can I log?

Strength, cardio, HIIT, mobility and sport are built in — running, cycling, swimming, rowing, boxing, yoga and more all map to a type. You can also add custom activity types.

Is my data private?

Yes. In local mode your data stays in this browser. If you choose account mode, it is stored in your own Firebase account and protected by ownership rules. We do not build advertising profiles or sell your data.

Can I export my data?

Yes. From Profile you can export a complete, restorable JSON backup plus a CSV of every set for spreadsheets — free on every tier, any time.

How do I delete my data?

Profile lets you erase your SmartFit data. Cloud users can also delete their Firebase account from the same screen; local users can erase the browser copy without contacting anyone.

How is this different from other fitness apps?

SmartFit keeps what a session is (its activity type) strictly separate from the recurring plan it belongs to — so your numbers always reconcile and progress stays honest.
