User Reviews

Users appreciate the app for its simplicity, accuracy, and usefulness in workout planning. It is reliable and fast, making it a favored tool over several years. However, some common issues include the absence of a numeric keyboard for easier input, limited weight increment options (only 2.5 kg), and problems with entering custom weights after recent updates.
