You already know what to do. The hard part is doing it — consistently, without burning out. Forge is built for that gap. Instead of an overwhelming program, you get two small, science-backed challenges each day. One might be a 10-minute walk. Another might be getting to bed 30 minutes earlier. Small enough to actually finish. Repeated enough to actually matter. EVERY CHALLENGE IS BACKED BY RESEARCH No vague wellness advice. Each challenge draws on real evidence — from sources like the U.S. Department of Health and Human Services, the American Academy of Sleep Medicine, and peer-reviewed research. You'll always know why a challenge is worth doing. DO IT WITH A TEAM Join or create a team of up to 15 people. Your team competes on a simple thing: showing up. You score points by completing your daily challenges — not by being the fittest person in the group. A beginner and a seasoned athlete contribute equally. It's accountability without the comparison. TALK TO YOUR TEAM Team chat is now built into Forge. Celebrate a teammate's full day, check in after a hard week, or just say hi. Real conversation, in the same place as your challenges — not scattered across a group text. SEE WHAT'S ACTUALLY WORKING The Insights screen surfaces patterns in your own data. Which habits you're keeping. Where your streak stands. What's quietly improving. Real feedback, not a wall of numbers. BUILT TO BE SUSTAINABLE Two challenges a day. Four pillars — movement, sleep, nutrition, and mindfulness. Apple Health integration that verifies your activity automatically, so completing a challenge is one tap. Daily reminders you control. No aggressive streak-or-die pressure. No noise. Forge isn't trying to overhaul your life. It's trying to help you do a few good things, most days, for a long time. Download Forge and start with today's two challenges.

Verdict

The call

MY J's advantage is ratings volume (73 vs 6) and iOS requirement (15.1 vs 26.4). On price, ads, in-app purchases and monetization model there is nothing between them.
