Analytics & PRs
A better way to log workouts than your notes app.
Flenex Fitness is the app behind Flenex — built around quick logging, clear targets and friend accountability, not local coaching or a physical gym listing.
Training focus
Pick strength, hybrid muscle and strength, or hypertrophy so targets match the way you want to progress.
Last session to beat
See the exact weights, reps and sets from last time, with smart suggestions for what to aim for next.
Strength analytics
Track every exercise and muscle group through volume, max weight, personal records and long-term progress.
Calculators and journeys
Estimate one-rep maxes, PR timelines, calories, macros and body-weight goal timelines from real training inputs.
Food tracking
Log meals, search foods, scan barcodes and compare calories, protein, carbs and fats against daily targets.
Friends and Snaps
Share gym check-ins, follow public influencer accounts and use friendly accountability to get more people training.
Log every session, day by day.
Swipe day-to-day, jump back to any past workout, and pick up right where you left off. Your history is always one tap away.
- Log every set, rep and weight in seconds — day by day
- Keeps count of how often you train each week
- Motivating nudges on the days you're scheduled to work out
- Jump to any past date, right back to your first-ever session
Set your routine once. Flenex handles the rest.
Choose the days you train and the muscle groups for each. Or pick freestyle and decide on the day — Flenex loads the exercises you already picked.
- Popular, compound exercises for every muscle group
- Add your own custom exercises anytime
- Edit your routine whenever your split changes
Beat last week — automatically.
On every training day we show what you hit last time and suggest the weight, reps and sets to aim for. Every session pushes you forward.
- Last session recap on every exercise
- "Aim for" targets based on your progress
- Never wonder what you did last week again
See your strength climb.
Track the percentage increase on every lift. Compare every Chest Monday, every Leg Friday, and watch your weight, reps and volume climb across weeks, months and years.
- Muscle-group and weekday filters
- Volume, max weight and rep progress charts
- Compare any session to every one before it
Chart your bulk or your cut.
Set a start weight, a goal weight, and log the ups and downs. Watch the line move toward your goal — save the journey when you hit it, and start a new one whenever your goal changes.
- Clean bulk, dirty bulk, or fat loss (fast or muscle-preserving)
- One-tap daily weight log with a clean progress line
- Save completed journeys so you always see how far you've come
Every number you need, worked out for you.
Four calculators built into the app — reading your real training history instead of a generic formula.
Estimated 1-rep max
No risky max attempt. Flenex reads your last 3 sessions on an exercise, shows the best one simply, and estimates the single you could hit today.
PR timeline
Name the 1-rep PR you want and AI works out how long it'll take, using the percentage increase across your last sessions on that exact exercise.
AI estimated weight loss & muscle gain timeline
A quick questionnaire — goal, training frequency, workout mix and session length — and AI returns a realistic week-by-week timeline with nutrition and recovery tips.
Calories & macros
Your daily calorie target and protein, carb and fat split, calculated from your goal, weight, height, age and how active you actually are.
Prove you showed up.
Beat your last session and Flenex asks if you want to snap it. Camera-only gym check-ins land on your friends' phones, glow on their Friends tab, and disappear after 24 hours.
- Camera-only check-ins — no camera roll, no faking it
- Glowing story ring on every friend who trained today
- Full-screen viewer with swipe and skip, gone in 24 hours
- Push notifications so nobody quietly skips leg day
Outlift your mates, fairly.
One overall strength ranking across your friends, built from your Flenex Score. Scores are normalised per exercise and body weight, so nobody climbs by swapping to an easier lift.
- Overall strength ranking, updated as you log
- Scored per muscle group and adjusted for body weight
- Capped work units stop volume farming
