## What is Lambda Tuner?

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.

## Key features

- 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


## Frequently asked questions about Lambda Tuner

### What is Lambda Tuner used for?

Lambda Tuner is a utility application designed to help users tune PID controllers. It calculates P, I, and D parameters using the 'Lambda method' for both self-regulating and integrating loops, making it suitable for various process industries.

### How does Lambda Tuner calculate PID parameters?

To calculate parameters, users describe their process with four specific values. Then, they select a Lambda value, which determines how quickly the controller should react. This method is designed to be intuitive and straightforward for users.

### Can I test my PID parameter settings with Lambda Tuner?

Yes, Lambda Tuner allows you to manually set PID parameters and test them. This feature helps you verify if your process description aligns with the calculation results and how it behaves in reality.

### Is Lambda Tuner suitable for learning about PID controllers?

Absolutely. The application can be used as an educational tool to understand the different impacts of P, I, and D parameters on a control loop. This helps users gain a deeper insight into controller behavior.

### What devices does Lambda Tuner support?

Lambda Tuner is available for iPhone and iPad devices, indicated by its support for 'iphone' and 'ipad'.

### What is the price of Lambda Tuner?

Lambda Tuner is a paid application, priced at $3.99. It does not feature in-app purchases or advertisements.

### How often is Lambda Tuner updated?

The latest version of Lambda Tuner is 2.1, and it was last updated on July 3, 2025. This indicates a recent update, suggesting ongoing development and support.

### What is the age rating for Lambda Tuner?

Lambda Tuner has an age rating of 4+, making it suitable for a wide range of users, including younger individuals interested in learning about control systems.

## Version history (last 5 releases)

### 2.1 — 2025-07-03

Updatet to iOS18

### 2.0 — 2021-01-02

It is now possible to save your settings. You can have several processes stored. The user interface has been updated, it now uses a regular tab bar. Compatible with iOS 14 and dark mode.

### 1.3.1 — 2018-03-16

For regions using comma as decimal separators, this is now corrected.

### 1.3 — 2018-02-20

Now it is possible to manually test different PID values to see how they behave in the process model described.

### 1.2 — 2017-11-13

Now there is a test funktion, where you can visualize how the controller will react with your settings. The function is using a process model whit your inputs and a PID calculation to generate the results. But a process model is only a model, your process is always more complex. It will not be 100% correct, but it gives you an idea of how it going to behave.
