Mesostrength vs RazFit

Mesostrength is a gym app built for lifters who train for muscle growth. You build a program, run it as a mesocycle, and log your sets as you go. The app tracks your performance and recovery, then adjusts weekly volume automatically. Too fatigued? It pulls back. Handling it well? It adds more. Between blocks you can see which muscles are growing, where you're stalling, and how strength is trending. The app includes a full exercise library, per-muscle volume tracking, and structured progressive overload. Built for intermediate to advanced lifters who care about programming across weeks and blocks, not just individual sessions. Works on any device, no app store download needed.
