A personal trainer in your pocket. You tell Arc your goals, your equipment, and how much time you can train, and it's turned into a personal strength training plan. At the gym, it progresses you through the workout so you know what to do next, how much weight to do, and how many reps. Have questions? Ask them directly to your personal "Coach". If you're not sure how to do an exercise, there's a video that shows you form. Every session you log stays on the progress screen so you can see the work adding up. Coach Pro automatically updates the plan as you get stronger. Built for simplicity. Made for consistency. The kind of app that makes showing up easy. Arc requires a subscription. You’ll see prices before you subscribe. Terms of Use: https://www.arcfitness.app/terms

Verdict
The clearest difference is update cadence: Arc at weekly against grav's every 10 months. grav's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 18.0). On price, ads and in-app purchases there is nothing between them.
