The core difference: Strong Free vs Strong PRO

Strong has long been one of the most respected minimalist workout loggers on the market. Its interface is clean, free of bloat, and fast between sets.

However, the difference between its free tier and its paid tier is defined by one primary bottleneck: the 3-routine limit.

• Strong Free: Lets you log unlimited sessions, use basic rest timers, and track weight/reps. However, you can only save 3 custom workout templates. If you run a standard 4-day Upper/Lower or 6-day Push-Pull-Legs routine, you cannot store your full program without manually editing or deleting existing templates.
• Strong PRO: Unlocks unlimited saved routines, warmup set tagging, plate calculator options, and comprehensive 1RM and volume progression charts. It costs $4.99 per month, $29.99 per year, or $99.99 for a lifetime unlock.

Strong feature comparison table

Here is the exact side-by-side feature breakdown between Strong Free, Strong PRO, and Stay Fit:

The 3-routine paywall in practice

If your training consists exclusively of a 3-day full-body split (Workout A, Workout B, Workout C), Strong Free works indefinitely.

The frustration hits the moment your training evolves:

1. Upper/Lower Split: Requires 4 routines (Upper A, Lower A, Upper B, Lower B).
2. Push-Pull-Legs (PPL): Requires 6 routines (Push A, Pull A, Legs A, Push B, Pull B, Legs B).
3. Deload Variants: Storing lighter deload variations alongside regular training blocks.

When you attempt to create a fourth template in Strong Free, an upgrade screen appears asking for a recurring subscription. For many lifters, paying $60 every two years simply to save routine templates feels like an unnecessary toll for local data storage.

What Strong PRO gets right (and where it earns its fee)

To be fair to Strong, their PRO tier isn't just a routine tax. It includes two features that justify the cost for specific athletes:

1. Apple Watch Integration: If you train without bringing your phone onto the gym floor and log every set directly from your wrist, Strong's watch companion app is remarkably mature and responsive.
2. Warmup Set Tagging: Strong PRO allows you to tag sets as "Warmup", "Drop Set", or "Failure", preventing light warmup volume from skewing your working-set analytics and estimated 1RMs.

If you are on iOS and rely heavily on your Apple Watch during workouts, Strong PRO is a well-engineered tool that earns its price tag.

The free alternative: Stay Fit vs Strong PRO

If you are an Android lifter carrying your phone to the rack, paying $4.99/month for routine slots is unnecessary.

Stay Fit was built specifically to remove routine paywalls:

• Unlimited Custom Routines: Build as many splits, cycles, and deload templates as you need.
• Full History & Analytics: Reports tab includes multi-week volume, workout frequency, duration, and muscle balance radar charts from your very first session.
• Zero Account & Offline-First: Your data lives on your device in local storage. There is no sign-up screen, no server downtime, and no subscription billing.
• Body & Goal Metrics: Track 9 body measurement circumferences, progress photos, and target weights alongside your lifts.
