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.
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.
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 links with JMRI or a dedicated module. 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 2.8 or higher, JMRI 4.16 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
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, and iPad mobile devices may use their own WiThrottle app simultaneously during an operating session. If you would like to sample WiThrottle, we offer a Lite version at no charge. This allows you to confirm compatibility before buying the full App.

Ratings and Reviews
This app works extremely well with my digitrax module. Response is immediate and is easier for me to use vice my dt400. I actually prefer my phone as a controller. I am able to control switches as easily as with a digitrax throttle.
UI graphics are inconsequential to the operation of the functions and provide excellent responses. Keep the improvements coming.
Absolutely fantastic. Everything it's supposed to be. I've been a model railroader for over thirty years but I'm new to DCC. I use a Sprog III DCC system but I really wanted a wireless controller for operations. This is the answer. In no time I was running not just one but two locomotives at the same time. It is so cool using my iPhone as the controller. Super easy to use controls. You can choose different options on controller configurations and a split screen option to run two locos at once. It's great being able to follow my train around the layout. Thanks for this app. It is just about the most enjoyable one I have.
Good, but Better UI Would Make it Great
This is an awesome solution for a low-cost DCC soft throttle, especially when compared to the cost of some of the hard throttles out there.
However, the user interface is garish and looks like it was put together with very little attention to the look & feel/aesthetics. Type is of various point sizes throughout and usually not well aligned. Graphics elements are extremely simple colored boxes - no gradients, shadows or anything but 90-degree right angles (everything is a simple rectangle). All of this combines to give the app a simplistic, almost toy-like appearance. It looks to the eye very much like this is an alpha version used for UI art concepting - not a final, marketed product.
Really hoping an update comes along to give this awesome, indispensable tool a much-needed facelift.
With Family Sharing set up, up to six family members can use this app.
