Use your iPhone, iPod touch, or iPad as a throttle for model railroad control!
**PLEASE NOTE** This App is not a stand-alone product! Other hardware and software are required.

WiThrottle Lite is the free version of WiThrottle.

Link to the popular JMRI software through a local Wi-Fi network to access throttle, address, and function controls wirelessly.
Connect directly to an MRC Prodigy WiFi module.
Connect directly to a Digitrax LnWi module.
Connect directly to a WifiTrax WFD-30/31 module.

Digital Command Control (DCC) is now the most common control method for earnest model railroaders, allowing multiple trains to be controlled simultaneously anywhere on the track. JMRI is an interface program that works with most brands of DCC and is very popular because it simplifies DCC programming, signaling, control, and many other aspects of running a permanent layout. It is also free and multi-platform.

Instead of direct control through the DCC system, WiThrottle Lite links with JMRI. This provides a universal interface to many possible combinations of technology and model railroads. As DCC evolves, JMRI is updated as needed to match current technology.

JMRI Requirements:
- JMRI 2.12 or higher, JMRI 5.0 or newer recommended
- DCC system interfaced to a computer and a model railroad
- Local Wi-Fi network

MRC Prodigy WiFi Requirements:
- MRC Prodigy WiFi module
- MRC Prodigy DCC system

Digitrax LnWi Requirements:
- Digitrax LnWi module
- Digitrax DCC system

WifiTrax WFD-30/31 Requirements:
- WifiTrax WFD module
- NCE DCC system

If you operate at either a club or private home that uses JMRI for operations and has Wi-Fi, access to the local network (host may need to share their password) is all you need. Multiple iPhone, iPod touch, or iPad mobile devices may use their own WiThrottle or WiThrottle Lite simultaneously during an operating session. WiThrottle Lite allows you to confirm compatibility at no cost before buying the full App.

Please visit our website for additional information. Our goal is to enhance your model railroading experience by providing convenient, wireless control of your existing system. WiThrottle is the final piece of the puzzle.

- No time limits or expiration on use
- Fully functional basic DCC throttle
- Speed and direction control
- F0 - F28 functions
- Acquire addresses wirelessly
- Adjust sensitivity of the throttle slider

I am in the process of building a very large multi deck layout. I had planned for WiFi throttles in my original design along with my Digitrax system. I had tried a couple other apps first and couldn’t get them to work with my LNWI but WiThrottle Lite worked like a charm the first try. I actually get a better throttle response with the app than I’d do with my handheld Digitrax throttles.

Very pleased.

A friend loaned me his Digitrax LNWI so I could try this app. Tech support helped me figure out a glitch - I was losing the signal if I closed my iPhone 8 screen. Sometimes when I woke it up, it was logging back on to my home router b/ I had the setting for it as “automatically join”. I’m very pleased. Plan to look at what the full version offers.

Very easy to use.

Great app. Very easy to use and configure. I have digitrax and use their LNWI adaptor. My grand kids like using the spare iPhone better than the regular throttles. I like that all the functions, the F1-F20 keys are separate. No need to use shift key. Very handy at acquiring and releasing engines. Now I need more iPhones.
