Most people train hard and remember none of it. You finish a session, you feel good or you feel flat, and by next week it's gone. No record. No pattern. No idea whether you're actually getting better or just getting tired. Forge fixes that. Log your sessions in seconds — rolls, rounds, lifts, calls, miles, whatever your game is. Then Forge does the part you can't: it reads your history back to you and tells you what's really going on. Not cheerleading. Not "great job." Real patterns pulled from your own numbers. Which days you show up sharpest. The mistake that keeps costing you. What separates the sessions where you're a problem from the ones where you're just there. The stuff you'd never catch on your own because you're too close to it. BUILT FOR HOW YOU ACTUALLY TRAIN Brazilian Jiu-Jitsu. Wrestling. Boxing. Kickboxing and MMA. Powerlifting. Running. Sales. Or build your own template for anything you want to get better at. Forge bends to your discipline instead of forcing you into someone else's checklist. WHAT YOU GET — Fast logging that fits your sport, not a generic gym app — AI insights after every session, tied to your real data — Progress charts that show whether you're actually trending up — A weekly read on your patterns and habits — Goals and streaks that keep you honest — Import your old spreadsheet and pick up right where you left off Talent is common. The people who pull ahead are the ones who pay attention. Forge makes paying attention automatic. Progress is built, not given. Come build it on purpose.

Verdict

The call

Interval Timer's advantage is ratings volume (19K vs 2) and device support (4 vs 2). On price, in-app purchases and monetization model there is nothing between them.
