What Makes Forge.OS Different
Not just a workout logger. Create long-term plans and training blocks like a coach. Run preset programs or build custom routines from scratch.
1RM tracking, volume trajectory, load distribution, growth percentages, and custom charts. See exactly where you're getting stronger.
Forge.OS captures what song was playing when you hit a personal record. Share your PRs with the soundtrack attached.
Have your friend scan your workout or routine QR code and train together. Or export your full plan as a Forge file for them to import.
A 6-layer progression calculator that detects stalls, adjusts for fatigue, learns your per-exercise increment patterns, and suggests your next weight.
No account. No cloud. No data collection. Everything runs on your device. We don't even have servers.
Tired of $10/month gym apps? Forge.OS offers a lifetime unlock for a single payment. No recurring fees, ever.
