Simplified gym log. ■ Press. Slide. Logged. Hold the start button and your routines fan out under your thumb. Slide onto the one you came here to do — one thumb, one motion, from anywhere in the app. Favorites sit closest to your thumb, and you can start empty and add exercises as you go. ■ Lift more. Tap less. The set ends, the timer starts, and you put the phone down. Rest runs in the Dynamic Island and on the Lock Screen — never unlock to check it, and never open the app to start the next set. Complete a set from the Lock Screen, or expand for the next exercise, sets left, and time remaining. ■ See where the load landed. Every set you log feeds a per-muscle recovery estimate, drawn on a body map. Not a single "readiness" number — seventeen muscles, each decaying at its own rate. Which muscle is most fatigued is reasonably reliable. How fatigued it is — the absolute number, the percentage — is a rough guide only. Sleep, nutrition, stress and age are not part of this calculation. ■ Week by week, exercise by exercise. See your progress, not just your logs. Every week is diffed against the one before it, and what moved is marked ++ or −. Every exercise keeps its own estimated 1RM, top weight and volume over time, with every set you have ever done under the chart. ■ Friends. Share only a summary of the workout you finished. Friends see that you trained, how long, how many sets, and which muscles — exercise names and weights only if you choose to include them. Your actual records, the sets and the notes, never leave your device. Per-exercise rankings — estimated 1RM, top weight, and sets this week — let you line up against friends who train the same lift. ■ Import anything. Export everything. Bring your history in from anything — another app's export, a spreadsheet, your own notes. Strong and Hevy CSVs import directly. For anything else, the app hands you a prompt that converts it, and RPE becomes RIR on the way in. Take it back out as JSON or CSV, as a file or straight to the clipboard in one tap. RIR, notes and warm-up sets all survive the round trip. It is one SQLite file on your device, with no third-party analytics SDKs. The schemas are public, so anything can read it. Including you. liftdiff.history/v1 · liftdiff.routine/v1 ■ The essentials. ・175 exercises ・RIR & RPE ・Supersets ・Warm-up & drop sets ・Plate calculator ・Rest timer ・Home Screen widgets ・Shareable images ・Per-muscle set counts ・Custom exercises ・Short-version routines ・Favorites ・iCloud sync ・English & 日本語
