Most training apps are built to keep you opening them. Vertex is built to tell you what you actually did.

LOG A SESSION IN SECONDS 83 exercises with illustrated instructions and form cues, or add your own. Supersets, drop sets, warm-up sets, and timed holds for planks and carries, because a four-minute plank is not one rep. A rest timer, kg or lbs, and a log that keeps working with no signal and syncs when you are back.

SEE THE MUSCLE, NOT JUST THE NUMBER Every exercise carries a curated muscle map, down to the individual head: front, side and rear delts, upper traps against lats, adductors against abductors. An anatomical figure shades what your week actually trained, so an imbalance is something you can see now instead of something you find out about in six months.

ANALYTICS THAT DESCRIBE, NEVER PRESCRIBE Weekly sets per muscle against the range the research supports. Your rep-range and intensity mix. A DOTS strength score from your squat, bench and deadlift. An overload rate and a least-squares trend for every lift, so a block that ends in a deload does not read as a collapse. Session length given as a median with its coverage stated, because an average session is one nobody trained.

PROGRESS YOU CAN ACTUALLY READ A consistency heatmap of your training year. Next targets on your main lifts. A muscle balance read on where your volume is really going.

A FEED OF PEOPLE LIFTING Follow the people you train with. Kudos, comments and photos on real sessions, with the full breakdown attached. Share a session with no photo and it draws itself as a map of the muscles you worked. A private account and follow requests whenever you want them.

YOUR GYM, ON THE MAP Clubs worldwide, rated by the people who actually train there, and leaderboards that compare like with like.

ON YOUR HOME SCREEN A widget for the week, and a Live Activity that keeps your set and your rest clock on the Lock Screen.
