Forge Client is the companion app for clients working with a Forge-certified coach. Every session your trainer logs shows up here automatically — with the sets, reps, weights, form videos, and photos from the floor — so you always know where you stand. WHAT YOU GET • Today Dashboard — Your last session, active goals, streak, and a one-tap weigh-in and daily check-in. • Goals With Real Progress — Set a target like "bench 225 × 1" and watch a three-tier progress calculation track every qualifying lift, every estimated one-rep max, and every personal record. No more staring at 0% until you hit the exact number. • Strength Journey — A session-by-session breakdown of any exercise, complete with photos, form check videos, and estimated 1RM trends so you can see how far you've come. • Personal Records, Automatically — Every PR your trainer logs is stamped, charted, and ready to share. • Check-Ins That Matter — Quickly log nutrition, sleep, stress, soreness, and energy. Your trainer sees the signal and adjusts your program. • Weight Journey — Log your weight when you want, see the trend line, and connect it to your training volume. • Session Media Gallery — Every photo and video from the floor, searchable by exercise. • Self-Log Workouts — Train solo? Type or voice-log a workout and Forge's AI parses it into structured sets, weights, and reps — instantly credited to your training history. HOW IT WORKS Your trainer sends you a sign-in link by email. Tap it once and you're in — no passwords, no setup. From there, every session, PR, and goal your trainer logs flows straight to your phone. Forge Client is designed to live beside your trainer, not replace them. It's the record book you both share.
