Iron Journal

Iron Journal is a strength training app that is designed to help you achieve your fitness goals by providing useful goal tracking features that are integrated into highly customizable workouts that you build from the ground up.
With Iron Journal, you can easily set and track goals for individual sets and exercises, including RPE, RIR, weight, rest, and rep goals.
Iron Journal's tracking features allows you to monitor rest times, exertion (RPE, RIR), weight goals, and provides total tonnage reports as well, so you can see how you're progressing over time.
Iron Journal also provides on-the-go information about your previous workout performance while you’re working out in a non-intrusive manner, so you can make adjustments to improve.
