LogBone

AI strength & physique coach

Free · Designed for iPhone. Not verified for macOS.

The training log with a memory. Your coach quotes your real numbers — HRV, RPE, sleep, stack — to call your next move. No ads. No tracking. Your data stays yours. LogBone is your AI strength coach — a fast, private training log with a coach that actually knows your numbers. TRAIN • Log sessions, sets, reps, weight and RPE in seconds — built for use between sets, mid-workout. • Automatic PR badges, fill-down prescribing, drag-to-reorder, and a rest timer that survives a locked screen. • Rate effort with a quick 1–9 scrubber, with a live heart-rate readout from Apple Watch. AI COACH • Chat with a coach that reads your recent training, recovery and available equipment. • Get a daily Morning Brief: what stood out, one recommendation, and what to log next. • Generate programs constrained to the equipment you actually have. BODY PROGRESS (18+) • Snap a physique photo and get an AI read on body-fat, muscle definition and what to focus on — with progress-aware notes over time. NUTRITION & WELLNESS • Log meals, supplements and skin. Snap a meal photo to estimate macros. • Type-to-pick from a supplement library with the purpose auto-filled. HEALTH • Optional Apple Health sync: steps, sleep, heart rate, HRV, weight, body fat, energy. MAKE IT YOURS • Full theming — pick any background and accent color, or save your own themes. • Apple Watch app, home-screen widgets, and branded share cards. PRIVATE BY DESIGN • No ads, no trackers, no data brokers. Body photos stay on your device. Export or delete your data anytime. LogBone is a coaching and logging tool, not a medical device.
