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.
