Rivu's strength-training log now has a fresh look on every screen. Share a stylish card after each workout and see every muscle group's growth in a single chart.
Rivu is a training log built for one thing only: strength training. No cardio tracking, no all-purpose fitness dashboard — just weight, reps, and progress, done beautifully.
If you want a clean, fast way to log your lifts and actually see your progress, Rivu is for you.
WHY RIVU
Body-Map Home Screen
An abstract body silhouette shades in by muscle group based on your last 4 weeks of volume — so you can see at a glance where you've been training hard, and where you haven't.
Automatic PR Detection
Every set you log is checked against your full history using an estimated 1RM (Epley formula) and max weight — so personal records are always detected automatically, never manually tracked.
Exercise Trend Graphs
Switch between estimated 1RM, max weight, total volume, and total reps to see exactly how each lift is progressing over time.
Built-In Rest Timer
The rest timer starts the moment you check off a set, so you can stay in rhythm without fumbling for a stopwatch.
Shareable Workout Cards
After every workout, generate a clean, story-ready image with your total volume, stats, and any new PRs — ready to share in one tap.
History Calendar
Look back at your training days on a calendar view, and filter by muscle group to see exactly when you trained what.
Simple Exercise Picker
Your most-used exercises surface automatically. Can't find a lift? Add your own custom exercise in seconds.

[A complete visual refresh]
Every screen now has a cleaner, more consistent design: Home, History, Analytics, workout logging, exercise details, badges, body metrics, Settings, and the purchase screen. Everything is easier to read and easier to use.
[New: share cards]
After a workout, turn your session into a stylish card and share it.

[See each muscle group's growth in one chart]
The Training Details tab in Analytics now overlays the max 1RM trend for every muscle group in a single chart. Values are shown as percentage change from the start of the period, so you can compare how each group is progressing. Tap a group name to show or hide its line.
[New for Starter plan]
The workout start screen now lists the recovery status of each muscle group.
