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. GOOD TO KNOW - Rivu is supported by ads (AdMob) - No subscriptions or in-app purchases at this time - No cloud sync — your data stays on your device Consistency beats intensity. Log it, see it, keep going — with Rivu. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is in-app purchases: Weight Log & PR Tracker at none against Fitty's 1. Fitty's advantage is ads (none vs shown) and update cadence (every 2 days vs every 8 days). On price, device support and iOS requirement there is nothing between them.
