📝 About this app

The GAINSFIRE workout tracker is your way to go if you are looking for a simple, fast & easy to use workout logger to record your personal development during weight training at the gym. With GAINSFIRE you can easily track your sets, weights, workouts and your overall progress.

Create custom training routines, add your own exercises or exercises from our catalog and start your workout. GAINSFIRE logs your performance just like a pen and paper workout diary.

The focus of GAINSFIRE is to quickly and efficiently record your performance and physical fitness. This includes the comparison of the current workout with past workouts in simple to understand statistics.

We deliberately refrain from explaining the correct execution of individual exercises. A professional trainer at your gym or a personal trainer does that way better than any app.

Highlights of the GAINSFIRE workout diary:

• Create your own workout routine (or multiple ones).
• Add exercises from our extensive catalog
• Define your own exercises and use them in your plans
• Get summaries after each training session
• Compare your performance with previous workouts
• Analyze your increase in weights or repetitions
• Add notes and your own comments to each exercise
• Define individual rest times for sets and exercises with customizable timers
• Archive workout routines for later use
• Share workout plans and statistics with your personal trainer or friends
• Messaging function for trainers and clients
• Direct analysis of each completed exercise
• Track body weight, body fat and muscle mass as well as body circumferences
• Automatic backup of your training data
• Use on multiple devices

A free one-time registration with your email address and a password of your choice is required for use.

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
