3.1.1 makes the program we recommend yours: change any exercise before you start. Updating from 2.x? Everything below is new for you. NEW IN 3.1.1 • The first program we recommend is a starting point, not a rule. Tap "Change exercises" to see every training day, swap anything your gym doesn't have from the full exercise list, or drop anything you can't do. Sets and rep targets carry over untouched. • Fixed: the confirmation after you build your first program could come up blank, taking the first session reminder with it. It appears properly now. NEW IN 3.1 • Your whole first mesocycle is free with the full engine. Change your mind before you finish week 3? Nothing is used up: the engine carries over to your next block. • Fill every training day in one tap. Pick Balanced, Upper body focus or Lower body focus, and each day gets a coach-written session for your day count with rep targets already set. Edit anything after, and the next block you fill rotates the exercises. • Starting out? Answer two questions and get one recommended program with its training days and first session shown before you start. Change the schedule right there, or browse every template. • The dashboard reads your calendar: "First session: Monday", "Planned for today", "Rest day today", "Today's work is done." • Reminders are offered when there is a session to remind you about, after you build a program or finish your first workout. No surprise permission prompts. • A proper "You're set" moment when you create a program, and a finish card with your sets after every session. • Set rows are quieter: last week's numbers only. Every explanation lives in the receipt behind the ? button. ALSO NEW SINCE 3.0 • Prescription receipts name the exact week your numbers came from and match the arithmetic beside them, with rounding you can reproduce on a calculator and a plain reason whenever a rep target lands outside your range. • Machine stacks: when a machine doesn't have the exact weight we prescribed, tap the weight and swap in what the machine actually has. The rep target recalculates so the set stays equivalent. • Deloads stay deloads: the weight menu never offers loads at or above the weight you are cutting from, and every prescription lands on a weight you can actually load. • Weight entry accepts comma decimals: 47,5 and 47.5 both work. • The effort intro says plainly what the prefilled RIR chip means: leave it alone and we record that you hit your target. • Passed on the engine earlier? You can start the subscription any time from Settings. EVERYTHING NEW IN 3.0 NEW PRICING Your first mesocycle is completely free with the full engine. After it, logging, history, and trends stay free forever, and the engine becomes a subscription. AN ENGINE THAT SHOWS ITS WORK • Weekly load and rep prescriptions computed from the weight, reps, and RIR you actually log • Prescription receipts: every recommendation comes with the arithmetic that produced it • Log RIR per set so the engine knows how hard each week really was • Rough day protocol: flag an off day and the engine adapts without letting one bad day drag your numbers down A MEMORY THAT SPANS BLOCKS • Week 1 comes prefilled from what you lifted last block • Compare completed mesocycles side by side and follow repeated lifts across blocks • Track volume trends with sets per muscle group, without waiting for the block to end FOR COACHES • Link a client with a 6 character code: no accounts, no spreadsheets • Build and deliver multi week programs straight to each client's phone • See logged results, effort, and adherence as your clients train • Message your clients right in the app • Turn on automatic weekly progression per client • MesoBuilder is completely free for your clients, and your first 2 clients are free for you. • On iPad, a coaching cockpit: templates, clients, and programs side by side Feedback directly shapes updates: support@mesobuilder.app

Every explanation lives in the receipt behind the ? button. ALSO NEW SINCE 3.0 • Prescription receipts name the exact week your numbers came from, so a rough day you held back, or a program a coach sent you, is never described as "last week." • Every line of a receipt matches the arithmetic beside it, with rounding you can reproduce on a calculator and a plain reason whenever a rep target lands outside your range. • Machine stacks: when a machine doesn't have the exact weight we prescribed, tap the weight and swap in what the machine actually has. The rep target recalculates so the set stays equivalent. • Deloads stay deloads. The weight menu never offers loads at or above the weight you are cutting from, and a rough or strong day adjustment lands at the weight your machine actually has. • Weight entry accepts comma decimals: 47,5 and 47.5 both work. • Prescriptions always land on weights you can actually load: deloads always reduce, holds hold, and progressions no longer stall on exact ties. • The effort intro says plainly what the prefilled RIR chip means: leave it alone and we record that you hit your target. • Passed on the engine earlier?

NEW IN 3.0.3 • Prescription receipts now name the exact week your numbers came from, so a rough day you held back, or a program a coach sent you, is never described as "last week." • Every line of a receipt matches the arithmetic beside it: rounding you can reproduce on a calculator, and a plain reason whenever a rep target lands outside your range. • Deloads stay deloads. The weight menu no longer offers loads at or above the weight you are cutting from, and it keeps saying Deload when you swap in a different one. • Pick the weight your machine actually has, then flag a rough or strong day, and the adjustment now lands at that weight instead of reverting to one your machine cannot make. • The effort intro now says plainly what the prefilled RIR chip means: leave it alone and we record that you hit your target, and next week is built on that. ALSO NEW SINCE 3.0 • Machine stacks: when a machine doesn't have the exact weight we prescribed, tap the weight and swap in what the machine actually has. The rep target recalculates so the set stays equivalent. • Weight entry accepts comma decimals: 47,5 and 47.5 both work, so fractional weights log correctly on keyboards without a period key. • Prescriptions always land on weights you can actually load: deloads always reduce, holds hold, and progressions no longer stall on exact ties. • Passed on the engine earlier?
