StrongLifts Weight Lifting Log

What it does

StrongLifts is a digital workout log and planner designed specifically for the 5x5 strength training methodology. The app's core function is to provide a structured workout routine, automatically calculate weight progressions, and make it simple to track sets, reps, and rest periods during a gym session. It serves as a digital replacement for a traditional paper logbook, adding intelligence and progress visualization.

Where it shines

StrongLifts excels in its focus and efficiency. The workout logging screen (01:14) is a prime example. It presents the day's exercises with simple, tappable circles for each set, eliminating any need for complex data entry during a workout. This makes tracking nearly frictionless. The app also includes thoughtful power-user features, like the ability to copy exercise settings (01:23), which saves significant time when customizing a program. The progress charts (03:57) are clean and provide essential metrics like estimated one-rep max (e1RM) and total volume, offering clear visual feedback on strength gains.

UX highlights

Frictionless Logging: Tapping a circle to complete a set (02:00) is fast and requires minimal interaction, which is ideal during a workout.
Clear Information Hierarchy: The main dashboard (01:11) shows the upcoming workouts clearly, with dates and exercises, making it easy to see what's next.
Contextual Exercise Info: When viewing an exercise, users can toggle between weight settings and a 'Form' tab (01:36) with instructional videos and text, providing help right where it's needed.
Efficient Customization: The 'Copy Settings' feature (01:23) allows users to apply progression and rep schemes across multiple exercises at once, a huge time-saver.
Program Modularity: The app allows users to easily swap main lifts or add pre-selected 'Assistance' packages like 'Chest/Back' (03:05), offering flexibility beyond the basic template.
No-Nonsense Design: The app uses a dark, high-contrast UI with a clear focus on data and actions, avoiding distracting visual elements.

Monetization & growth

The app funnels users directly from its onboarding quiz to a paywall at 00:32. The primary offer is a 7-day free trial for an annual subscription. The paywall builds value by listing features and builds trust by including social proof ('+100,000 5-star ratings') and a transparent timeline of the trial process. Tapping on the price reveals a sheet with multiple plans (00:43), including monthly and lifetime options, catering to different user preferences.

Who it’s for

This app is clearly designed for individuals serious about strength training, specifically those following or interested in the 5x5 program. The language used ('Squat +95kg', 'Deload', 'OHP') assumes a certain level of familiarity with weightlifting. It's not for casual gym-goers but for dedicated lifters who want a tool to meticulously track progress and enforce a structured, progressive overload plan.

Notes & opportunities

While the focus is a strength, the user interface feels somewhat dated, relying heavily on standard iOS components without much custom design flair. The process of editing a workout by removing an exercise (02:26) is straightforward but could be more intuitive; a long-press or swipe gesture might feel more modern than navigating through a modal. Finally, while the workout summary screen is motivating (02:14), adding more detailed insights or performance highlights from that specific session could provide even greater value and reinforcement.
