## What is HMI Editor?

HMI Editor is a *native* iOS application for creating Human Machine Interfaces for real-time monitoring and control of industrial PLC based systems and processes. Data is presented in highly customizable page layouts much like a presentations app. 

Who's this for.

The app is aimed at automation engineers or industrial machine manufacturers on many sectors including but not limited to building automation, industrial processing, power plants, water plants, industrial equipment, transportation and so on, who want to provide instant, reliable access to real-time data right from iOS devices.

What you'll get for the price of the app.

HMI Editor allows you to create efficient, advanced, highly responsive "Human Machine Interfaces" right on your iPad screen with unprecedented ease of use and fun. The HMI Editor app is fully native and supports all major Programmable Logic Controller (PLC) brands. For the price of the app (FREE) you can *fully* develop and test projects of any complexity. No restrictions on number of pages, tags or PLCs are applied at this stage. You only pay for project activations when you are ready to deploy to end users.

HMI Editor essential Features.

- Very fast, launches and connects immediately regardless of project size.
- All data types including Strings, Arrays and Dictionaries fully supported.
- HMI Projects are edited on-screen as you run and monitor your process.
- You can export and edit your project files as text on your PC or Mac.
- Export/import asset files such as images, pdfs or audio files from HMI Editor to your PC or Mac. 
- Optional project storage in the cloud and easy deployment to end users devices.
- Native PLC communication protocols. Connections are performed with no intermediate servers or boxes.
- Major PLC brands supported, including: Allen Bradley, Mitsubishi, Omron, Opto 22, Schneider Electric, Siemens, Wago.
- TCP/IP based security.

Getting Started: creating a HMI Editor project.

Projects are created like a mix of PowerPoint and Excel. The concept is quite simple. You lay out elements such as Sliders, Switches, Buttons, Images, Text Fields, Knobs, Trends, Gauges, Bar Indicators, Web browser, Array pickers, even Gesture Recognizers and much more onto pages. You connect on-screen objects with iPad sensors and PLC tags through simple links or powerful expressions. That's it !!. The result is a stunning, dynamic, real-time presentation of your PLC controlled process as you'd never imagined.

Examples Ready for You.

Explore the examples and take the liberty to make changes on them. Create your own test projects from scratch or based on the examples. HMI Editor will comprehensively tell you what inconsistencies or problems there may be in your project as you build them. New examples are being added on a regular basis or by user request.

What's Next.

There’s a lot more that we haven’t mentioned here, such as the page navigation interface, the embedded file server, the model browser, the model seeker, the automatic expression completer, the inspector viewer, alarm notifications, iPad sensors, barcode scanner, user access levels, password on launch, PLC validation codes, individual tag diagnostics, background processing, automatic network switching, and much much more. You surely will identify some of these features by just exploring the app, but the single source where everything is covered is the HMI Editor Reference Manual. Feel free to download it from our site and look at the full possibilities, you’ll love the product.

### 5/5 — Excellent App

*2026-04-04*

Took a little bit to get used to the developer interface (which is totally understandable on a new app), but now it’s second nature. Tools available more than meet my needs to provide a lower-cost interface for a machine we’re developing. Ran into a technical issue recently, and the technical support I received was beyond expectations. I highly recommend this app.

### 2/5 — iMac

*2021-10-25*

A desktop version would be very useful.

**Developer response:** We’re working on this. But if you have a M1 Mac, this will work on the desktop.

### 5/5 — Hmi

*2021-09-16*

Very beautiful interface

### 5/5 — Great software

*2018-06-26*

Easy to use and deploy....love it

## Version history (last 5 releases)

### 0.6.0 — 2026-05-30

Bug Fix.

### 0.5.8 — 2026-05-19

This release improves the Inspector, Model Browser, REST API, VPN, and Alarm workflows with better search, layout polish, and navigation refinements.

It also adds more flexible color start point options for Chart, Trend, and BarLevel items, improves stepped and haptic feedback behavior for controls, and fixes multiple stability, layout, and compatibility issues across iPad, iPhone, and Mac.

### 0.5.7 — 2026-05-07

What's New in 0.5.7

New connectors
• MQTT Connector — publish and subscribe to topics on any MQTT broker. Supports username/password and TLS, automatic JSON parsing of received payloads, and a last-message viewer with syntax-highlighted JSON.

Editor
• Frame properties (framePortrait, frameLandscape, framePortraitPhone, frameLandscapePhone, frameMac) now use four separate fields — X, Y, Width, Height — instead of a single SM.rect text box. Each field accepts an expression, and your expressions are preserved across project close and reopen.
• The top toolbar turns blue when you enter Edit mode, so it's clear at a glance whether you're editing or running.
• New "Move Items to Another Page" action that preserves item names and expression bindings.
• New "Default Start Page" setting under Current Project — pick the page that should open first.
• The Pages list opens automatically after a copy, so you can pick a destination immediately.

Items
• Slider: new stepValue property — when set to a positive value the slider snaps to multiples of that step (set to 0 for the previous continuous behavior).
• Inspector connectors (PLC, REST, MQTT, VPN) now share a unified header: connector name, endpoint or broker, and a live-status dot.

Fixes
• Fixed the Model Browser flying off-screen when the search bar was tapped.
• Fixed several Model Browser search bugs — crashes on rapid input, missing VPN and Background results, and stale state on reopen.
• Fixed sub-pixel position drift when moving, resizing, grouping, and ungrouping items.
• Fixed a crash when loading older projects that contain TapRecognizer items.
• Fixed copy of REST connectors whose response property contains an array value.
• In SM.rect editors, expressions like pageWidth - 20 are no longer replaced by their evaluated number after editing.

### 0.5.5 — 2026-03-19

Updated app for iOS 26. Fixed a bug that prevented app access local networks in iOS 26.

### 0.5.4 — 2025-05-23

This build fixes a bug on verification alert prompts in iPadOS, showing now the cancel button, and fixes the paste action of items within the model browser.
