I built StewardFit to help with my own training. When I started lifting consistently, I was frustrated that I could not remember the details of my last workout. Did I lift 100 lbs for 6 reps or 95 for 8? Vague memory meant vague improvement.
Ridgway (and Deming) noted that what gets measured gets managed — so measure the right things.1 For the measure you use, it will be measured to you (Luke 6:38).
So I designed an app that measures the work: routines, weight, sets, reps, time under tension (TUT), perceived effort (RPE), and rest between sets.
Then I added calculations that help: estimated 1RM, volume, TUT per rep, and StewardFit NWI — one Goal Success Score named for your goal (Growth, Endurance, or Strength). That core, plus CSV export, stays generously free. You always own your data.
Charts and cloud backup let you follow the whole journey, from last session through years of training, and they keep the log safe if you lose the phone. Both are StewardFit Pro. StewardFit is an instrumented gym logger — built to measure training, not just count sets — with a quiet verse during rest. Scripture is part of the experience, and audio is available when you want to listen.
Be strong and courageous, and do the work (1 Chronicles 28:20).
