PowerlifterWeightlifting Log is a free iPhone app developed by Charles Vanderhoff. It is a lifestyle app in the Health & Fitness category that aims to help users track and automatically calculate their Wendlerpowerlifting routine.

With this app, users can input their one rep maxes, and the entire Wendler routine will be calculated based on their input. This eliminates the need to refer to percentage or weight charts and simplifies the training process. The app automatically increases the weight for each lift with each new cycle, customizing the program based on the user's lifting style and fitness level.

The app offers several features for free, including tracking scores, warmup sets, rest timer, one rep max calculator, unit customization, and a complete history of workouts. It is especially designed for powerlifting or CrossFit enthusiasts.

For users who want additional features, the Wendler Log Pro version is available for purchase. This version includes an assistance program creator, pre-built customizable assistance programs, a plate calculator, graphing of one rep maxes over time, automatic backup and sync to the cloud, and an ad-free experience.

If users encounter any issues or have suggestions for improvement, they can easily contact the development team through the app's Help Center.
