About this app

~ A simpler way to track your Working Sets ~ Working Sets is a minimal and simple workout tracker designed for people looking to build muscle and make progressive size gains without the noise. Custom Templates and Progress Feedback • Working Sets deliberately doesn't contain presets or existing models, it's designed to work how you do without ads, privacy invasive activities or clutter. • You can sync with Health to read health data and save workouts without the need for a wearable. • Working Sets learns about your activity securely, on-device, and shows you how much stronger you are week-to-week. Suggested Sets, Simple Summaries and Calendar Progress • During your workout, any exercise that contains three sets of at least 8 reps at a certain weight will generate a suggested increment of weight for that rep range. If your reps aren't quite at 8 but you've hit the same weight at a few different rep ranges, Working Sets will recommend based on an average. • Post-workout you'll get a summary which showcases any PRs for that session and your max weight and max rep range per-exercise. • From the main home view you can see your workouts for the month at a glance. Simple! Home Screen Widgets, Live Activities and Customisation • Customise basic settings such as which days you work out, what day you consider the start of the week, your average rest time, the app's accent colour and which app icon you prefer. • Also launch Working Sets from your home screen with useful widgets that show either your schedule for the day/week, or your last working session. Apple Watch • If you use Apple Watch, you’ll now be able to install the companion app to see your current working set, update the weight/reps and complete it all without looking at your phone. Premium Features • Set weekly workout commitments and track your progress toward your goals with visual feedback • Celebrate reaching your weekly workout targets with visual rewards and progress tracking • Get detailed workout analysis that compares your current performance to previous sessions • Assign muscle groups to exercises and track which areas you're targeting most • Premium subscriptions available monthly or yearly with significant savings on annual plans Full terms of service available at https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Baseline captured. Growth appears after the crawler observes a changed rating count.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
