About this app

Volstack is a strength training tracker built for serious lifters — not casual gym visits. Log your sets fast, and Volstack automatically analyzes your training: personal records, weekly tonnage per muscle group, stagnation alerts, and recovery status.
Most gym apps store your data. Volstack turns it into insight — before plateaus cost you weeks of progress.
✨ CORE FEATURES
• Fast Workout Logger — log weight and reps with minimal taps. Editable workout duration timer. Works offline; syncs when you're back online.
• Automatic PR Detection — every set is analyzed. Personal records and estimated 1RM are tracked automatically — no manual entry.
• Volume & Tonnage Analytics — see how hard each muscle group is working: chest, back, shoulders, arms, core, legs. Weekly tonnage and set volume at a glance.
• Personalized MEV/MRV Targets (PRO) — volume benchmarks tailored to your muscle or strength goal, sex, age, and experience level.
• Stagnation Alerts — get notified when an exercise or muscle group stops progressing, so you can adjust before frustration sets in. Uses your full training history.
• Recovery Body Map (PRO) — visual muscle readiness after each session. Know which muscles are ready to train and which need rest, with ACWR overload alerts.
• Muscle Imbalance Analysis (PRO) — detect antagonist imbalances (e.g. chest vs back, quads vs hamstrings, biceps vs triceps) before they become injuries.
• 1,300+ Exercises — searchable library with GIFs, instructions, and target muscles.
• Routines — build and save workout templates. Start from a routine or log ad-hoc sessions.
• Post-Workout Insights — personalized summary after each session based on your training goal, plus a muscle breakdown map of what you trained.
• Workout Share — export a shareable image of your session for social media.
• Weekly Goal & Streak — stay consistent with weekly session targets and week-over-week streak tracking.
