## What is Megatuner Plus?

Introducing an Advanced PID Controller Tuner for iOS.

The Megatunes Plus app makes the tuning of your PI/PID controllers of (generally) noisy & possible interacting process loops easier. Using data from your control loop experiments. Our advanced algorithms analyze the data to help you find the optimal settings for your controller, ensuring optimal performance and stability. 

Example processes: Chemical processing plants, Power Plants, ship position control, to mention some.

Features:
* Advanced PI/PID Controller Tuner for generally noisy & possible interacting process loops.
* User-friendly interface for simple and efficient data input and analysis
* Advanced algorithms for accurate and precise model and controller tuning
* Convert your PID controller parameters over 20 different DCS vendor forms.

Whether you're an experienced engineer or just starting out, our PI/PID controller tuner app for iOS can help you fine-tune your control loop and improve your process control system. Download now and start optimizing your loops today!

Improvements:
* Automatic pairing of the input (MV) and the output (CV) variables (i.e. the "Auto Pairer" button on "Pairing" page) are now free.
* Improved efficiency of the underlying system identification routine.

### 1.1 — 2023-07-16

Improvements:
* Often when trying to drag a slider (e.g. on the tuning page), the whole page would be unintentionally dragged. The sliders are now easier to drag.
* Added correct Youtube Video Demo link on the first Account page. The video shows a quick walkthrough of the app.
* Better efficiency in the underlying routines of the tuning page.
