About
Strontr is the workout app built for lifters, runners, and anyone who wants structured training without the spreadsheet. Plan your gym splits, log every set, track runs and walks, and watch your fitness evolve week after week.
WORKOUT PLANNING
• Build custom training splits with any number of days
• Merge days into combined sessions when life gets busy
• Assign workouts to specific days, or leave them flexible with "Any Day"
• Merged days stay pinned to the top so you can find them fast
SMART LOGGING
• Quick set logging with weight, reps, RPE and notes
• Rest timer that starts automatically between sets
• Exercise history at a glance — see your last performance on every lift
• Personal records tracked silently in the background
EVOLVE PLANS
• Let Strontr progress your program for you
• Automatic weight and rep adjustments based on how your last sessions went
• Consistent exercise naming so your history never breaks
CARDIO & RUNNING
• Quick-start a run, walk, or hike with a single tap — no setup, no program
• Or follow a structured running program with intervals and pacing
• Track distance, pace, time, and route until you manually end the session
CLEAN, FAST, FOCUSED
• Designed for one-handed use between sets
• Works offline at the gym
• No ads, no clutter, no social feed — just training
Strontr is the clean, focused workout app for strength training and cardio. Build gym splits, log every set, follow evolving programs, track runs and walks, and keep your training organized without the spreadsheet.

What's New in Strontr
10.20.12
September 14, 2026
Fixes and improvements: - The merge bar for Evolve days now floats above the tab bar so it stays in reach while you scroll, and you can save a merged workout for later straight from it. - Reps and rest fields now use a number keypad, so a stray decimal point can't sneak into a whole-number field. - Machine increment settings now land on weights you can actually load, and existing plans correct themselves on launch instead of waiting for next week. - Rest times in the plan editor now match what the workout actually gives you. - Merged workouts saved for later no longer disappear after syncing, and deleting one now clears it from your other devices too.
