MesoBuilder

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 • Start your next block with suggestions from your own training history. Tap Use suggestion for each set, or enter your own reps and weight • 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 55 ready made templates or from scratch • Log weight, reps, and RIR for every set, with notes for each exercise • Live workout timers and Home Screen widgets keep sessions on track • Sync training across your devices through your personal iCloud account when iCloud is available and enabled Engine prescriptions beyond your first mesocycle require an Individual or Coach 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 your clients' logged results, effort, and reported training days • Message your clients right in the app • Choose smart weekly suggestions or manually set the targets clients see • Clients can follow your programs and log their workouts for free • 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 and wider screens, use the extra space for workout logging, templates, history, and coaching. Manage your client roster and client details side by side. ---- PRIVACY FIRST Your personal training data is stored on your device, with iCloud sync available through your own account using Apple's CloudKit. The developer cannot read your private iCloud data. 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.
