MesoBuilder

Version 2.1 includes major improvements to mesocycle setup, scheduling, navigation, and overall app polish.

MesoBuilder is a strength-training planner built for lifters and coaches who use structured mesocycles. Create training blocks, log every set and rep, and keep progression organized in one place, without spreadsheets. Use Home Screen widgets and live workout timers to stay on track during training.

MesoBuilder adapts to both lifters and coaches, offering tools tailored to individual training as well as professional coaching workflows.

Note: Some advanced features, including multi-week programming, personalized progression suggestions, and coach tools, require an active subscription.

Progressive Overload, Automatically Calculated

MesoBuilder’s built-in progression algorithm analyzes your previous week’s performance and suggests updated loads and reps for the next week. This removes guesswork and helps keep progression consistent, measurable, and personalized.

Progression suggestions require an active subscription.

For Lifters

• Build mesocycles with clearly defined weeks, days, and exercises • Log weight, reps, RPE, and notes for every set • Track performance and progression over time • Access personalized progression suggestions with a subscription

Some lifter features require an Individual subscription.

For Coaches

The Coach subscription is designed for professionals who manage athletes and also use the app for their own training.

In addition to all Individual features, Coach subscribers can: • Create and manage programs for multiple athletes • View athlete workouts, adherence, and logged results • Enable automatic weekly progression suggestions for clients • Adjust upcoming training weeks based on performance and notes

This allows coaches to use MesoBuilder as both a personal training tool and a client management platform, all within one app.

Coach features require a Coach subscription.

Privacy-First by Design

MesoBuilder was built with privacy as a core principle. Training data is stored securely in the user’s personal iCloud account using Apple’s CloudKit. No third-party servers are used, and the developer cannot view or access user data. All data remains protected by Apple’s privacy and security infrastructure and is tied to the user’s Apple ID.

Built by a Lifter Who Wanted Something Simpler

MesoBuilder began as a personal tool created by a lifter who wanted a practical way to build mesocycles without the high prices or unnecessary complexity common in fitness apps.

Today, MesoBuilder is still independently built and maintained with a focus on clarity, structure, and real-world training workflows for both lifters and coaches. Every feature is designed around how people actually train, without spreadsheets, guesswork, or bloated systems.

Feedback is always welcome, and user input directly shapes future updates.

MesoBuilder keeps training organized and progression clear so you can focus on lifting, not managing tools.
