LFTD vs
Strong.

Why pick LFTD
- Free vs $30/yr (or $99 lifetime)Strong charges to remove the 3-routine limit. LFTD has no limits at any tier.
- Set types matter for serious liftersStrong counts every set as a working set. Your warmup pollutes your PR charts. LFTD separates warmup/working/dropset/failure properly.
- Weekly muscle volumeThe core hypertrophy metric — LFTD tracks weekly working sets per muscle group. Strong doesn't.
- Protocol trackingStrong has zero TRT or peptide functionality. LFTD has dosing compliance, site rotation, recon calculator, inventory.
Why pick Strong
- Apple Watch is best in classStrong's watchOS app is genuinely excellent. Log sets from your wrist. LFTD has no watch app yet.
- Apple Health & Siri shortcutsNative ecosystem integration. LFTD doesn't sync to Apple Health.
- Larger exercise library with demo videos300+ exercises with video demonstrations vs LFTD's 135 with no videos.
- Lifetime purchase option$99 once and you're done. LFTD doesn't have a lifetime option (because everything is already free).
Honest verdict
Strong is the better choice if you live in the Apple ecosystem (Watch, Health, Siri) and you don't run any kind of compound protocol. LFTD is the better choice for everyone else — free, more rigorous tracking (RPE + set types), proper weekly volume per muscle, and the only app that combines workout tracking with TRT/peptide management. If you're a powerlifter who just wants a clean logbook on your wrist, Strong wins. If you're a hypertrophy-focused lifter who tracks compounds, LFTD wins.
