Lambda Tuner vs Tool2Tune
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Lambda Tuner
This tool helps tune PID controllers using the Lambda method to calculate P, I, and D parameters. It's designed for intuitive use in various process industries and works on self-regulating and integrating loops. You can also use it to learn the impact of different PID parameters.
- Lambda method for PID parameter calculation
- Supports self-regulating and integrating loops
- Intuitive and easy to use interface
- Adjustable Lambda value for reaction speed
- Manual PID parameter testing
- Educational tool for PID parameter impact

Lambda Tuner is a tool for tuning PID controllers. It is using the “Lambda method” to calculate the P,I and D parameters. It works on self-regulating loops and integrating loops. It's designed to be intuitive, easy to use and is suitable for any kind of process industry. To calculate the parameters you need to describe your process with four values. After that you select the Lambda value, thats a value of how fast you want your controller to react. You can test to manually set the PID parameters, to test if your process description behaves similar in the calculation as in reality. It can also be used as a tool to learn the different impact of the PID parameters.
