MesoBuilder is the training app that shows its work. Build multi week mesocycles for hypertrophy and strength, log every set, and get weekly load and rep prescriptions you can actually check: tap any recommendation to see the exact numbers behind it. No black boxes, no spreadsheets. 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 progression prescriptions computed from the weight, reps, and RIR (reps in reserve) you actually log • Prescription receipts: every recommendation comes with the arithmetic that produced it • Effort aware: 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 the session without letting one bad day drag your numbers down • Machine stacks: swap a prescribed weight for what your machine actually has and the rep target recalculates to match ---- A MEMORY THAT SPANS BLOCKS • Never start a block cold: week 1 comes prefilled from what you lifted last block • Compare completed mesocycles side by side • Track volume trends with sets per muscle group • Follow repeated lifts across training blocks to see long term progress • Check mid block trends without waiting for the block to end ---- FOR LIFTERS • Build multi week mesocycles from 26 ready made templates or from scratch • Log weight, reps, RIR, and notes for every set • Live workout timers and Home Screen widgets keep sessions on track • Your data backs up to your personal iCloud and syncs across your devices Engine prescriptions beyond your first mesocycle require an Individual subscription. Logging and history never do. ---- FOR COACHES Coach clients remotely without accounts or spreadsheets. Your client enters a 6 character code and you are linked. • 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 • Coach includes everything in Individual, so your own training keeps the full engine Your first 2 clients are free with full features. A Coach subscription expands your roster. ---- DESIGNED FOR IPHONE AND IPAD On iPhone, MesoBuilder is the logbook in your pocket. On iPad, it becomes a coaching cockpit: manage templates, clients, and programs side by side. ---- PRIVACY FIRST Your personal training data is stored in your own iCloud account using Apple's CloudKit, where the developer cannot read it. If you link with a coach or client, the programs, results, and messages you exchange are delivered through a MesoBuilder operated relay and deleted on a fixed retention schedule. Analytics are anonymous and privacy preserving. ---- BUILT BY A LIFTER MesoBuilder is independently built and maintained by a lifter who wanted a more honest way to plan training. Feedback is always welcome, and user input directly shapes updates.
