Less time logging. More time lifting.

Auto-queued sets, self-starting timers, per-set photos and video. Works offline, syncs when you're back online.

Get for Android Open in Browser

iOS: open in Safari, tap Share, then "Add to Home Screen".

Six steps. Zero friction.

01

Start workout

Pick a session. Straight into the workout screen.

02

Log set

Weight, reps, one tap — logged instantly.

03

Timer starts

Log a set and the rest timer starts itself.

04

Next set queued

Next weight, reps, and exercise, queued automatically.

05

PR detected

New e1RM hit? Flagged the moment it happens.

06

Synced

Signed in and online — synced across every device.

Shipped with usable features, not AI slop.

Lift faster

Every second between sets belongs to you, not the app.

Your next set, already queued

Weight and reps carry forward from last session automatically. Show up, keep lifting.

The rest timer starts itself

Log a set and the clock's already running. No glancing at your watch, no extra taps.

Timer, notes, and bench angle — one tap away

A dedicated hotbar keeps your program, notes, and a built-in bench angle finder exactly where you need them, mid-set.

Track everything

Data you'd actually want to look back on.

Photos and videos, tied to every set

Attach a form check, a PR, or a progress shot or video to the exact set or exercise it happened on — not a generic media dump, findable exactly where you logged it.

PRs surface in real time

Every set feeds a live estimate. You'll know the moment you've set a record — not after.

Your whole history, not just today

Every session, every exercise, searchable and sorted — not buried in a chat log.

Make it yours

A home screen that fits your training, not a template.

Resize and rearrange your home cards

Widget-style cards you can size to fit what actually matters to you — from a single tile up to full width.

One-tap navigation

A bottom tab bar for Home, Train, Progress, Logs, and Settings — everything's two taps away, max.

Your exercise library, synced

Custom exercises you type once persist across devices — no re-entering the same movement every session.

Built to get you off your phone, not on it.

A typical tracker

A feed of other people's workouts
Streaks, badges, and gamification
A chatbot suggesting your next set
Five taps to log a single set
Ads, upsells, premium paywalls

SBL Tracker

No feed. Ever.
No streaks, no gamification
No AI suggestions — you know your program
One tap. Your next set's already there.
No ads. Nothing to sell you.

Your data. Your workouts. Your business.

Offline-first

Works with zero signal, in any gym basement.

Cloud synced

Never lose a session, on any device.

Your data stays yours

Export or delete it anytime, no questions.

No ads

Nothing to sell, nothing to click.

Minimal permissions

Only asks for what it actually needs.

Stop scrolling. Start lifting.

One file. No store, no fluff. Free forever — no account wall, no ads.

This is a direct APK, not a Play Store install. Android will warn about "unknown sources" — that's expected, not a red flag. Open the file, tap "Install anyway" when prompted, and allow storage/camera access if asked (used for form-check photos and videos, nothing else).

Good to know

Is it really free?

Yes. No subscription, no ads, no premium tier. The APK is a straight download.

Does it work without internet?

Yes. Every set logs instantly on-device and syncs to the cloud the next time you're connected.

Is there an iOS app?

Not yet. Use the web app in Safari and add it to your home screen for an app-like experience.

Can I export my data?

Your data is yours. Export or delete it whenever you want, no questions asked.

What devices are supported?

Android 8.0 and up for the native app. Any modern browser for the web app, on PC or iOS.
