What's New in Flux

8.7.0

September 15, 2026

Flux 8.7.0 updates the parts of the app you use most: Workout Complete, Routine Library programmes, the Dashboard Routine Overview, warm-ups in your active workout and the Generate Routine duration settings. WORKOUT COMPLETE IS NOW A SET OF CARDS Tap Finish Workout and instead of one long page you get cards you swipe through. First, rate how the workout felt. Next, your totals: time, weight moved, sets and exercises. Then one card per exercise showing what you planned beside what you actually did, how it compared with last time and your target for next time, with a quick 1–5 rating for that exercise. The final card shows the muscles you trained, as a body map or a chart. Save Workout stays at the bottom of every card, so you can save whenever you're ready. Flux also saves your workout before it opens Workout Complete. If the save fails, your workout stays paused with a Couldn't Save Workout message and a Retry Save button. Your sets are still there and nothing is counted twice. SWAP EXERCISES IN ROUTINE LIBRARY PROGRAMMES Following a programme but your gym doesn't have the kit? Open a programme workout, tap the exercise and choose Swap. Flux asks whether to change it for the whole routine or just this workout. Choose the whole routine and every remaining workout for that day (every Push Day, for example) uses the new exercise, and the change stays if you repeat the routine. Choose just this workout and only that session changes. Workouts you've already completed stay exactly as you trained them. You can also swap before you start: in Choose Routine, open a programme's details, swap what you need to, then tap Select Routine. DASHBOARD ROUTINE OVERVIEW FOR GENERATED ROUTINES The Routine Overview widget on your Dashboard used to give programmes a phase and progress bar but give generated routines only a workout list. Generated routines now get the same view: your current phase, your position (such as Wave 2 · Week 4 · Workout 2 of 4), a bar that fills as you complete workouts, and your next milestone. SMARTER WARM-UPS IN YOUR ACTIVE WORKOUT For compound lifts in generated workouts, the warm-up sets Flux adds are now sized to today's working weight, reps and effort, and built from the plates and increments in your gym setup. A hard 30 kg dumbbell press gets a proper ramp; a light barbell lift gets a short one. Change your first working weight during the workout and the warm-ups you haven't ticked off update to match, while the ones you've completed keep their weights. GENERATE ROUTINE: CHOOSE YOUR SESSION LENGTH The Duration setting when you generate a routine now offers 30 min, 30–45, 45–60, 60–75 and 75–90 minutes. New routines fit their time more reliably, automatic supersets are kept in check and weekly muscle balance is steadier. When a session still runs long, Flux now turns a set into a lighter, shorter-rest back-off set instead of removing it. ALSO IN THIS UPDATE • Edited routines: the targets shown in the workout editor, the active workout and Workout Complete now match, and earned weight increases are saved to your routine for next time. • Workout history that mixes kilograms and pounds now compares correctly. • Paywall: once your trial ends, a Share feedback button lets you tell us why you're not unlocking Flux. • The Failure Reasons sheet no longer overlaps its Done button, and duplicate profiles left by older versions are tidied up automatically.

User reviews

Great app for creating and tracking workouts

Love this app to create workouts based on parameters, such as gym, muscle group, type of workout and duration. Then easily swap the exercises on the routine or individually on the day of. Really great UI to see, manage and track each exercise. Love the dashboard feature and muscle set frequency and volume graphs. Built in a way that naturally flows with the way I like to use a workout app and track progress. Highly recommend it! And I've tried Hevy, Alpha Progression, Gymverse and even made my own web based app. Flux takes the best of each workout app and improves on it.
