iOS Device Compatability, Bluetooth, and ANT + Adapters



With the launch of The Sufferfest Training System for iOS devices, we've made suffering more convenient than ever. Gone are the days of lugging your desktop, monitor and all, to the gym. No longer do you have to drag your laptop into your Torture Chamber, risking damage from a wayward swing of an enthusiastic minion's flogging stick. Mobile Suffering is here.

Before we get down to the business of sending you headfirst into the hurt locker we need to talk a bit about compatibility between The Sufferfest Training System and Apple iOS devices. Technology is constantly changing, and older devices may lack the processing power or hardware capabilities to support the full suite of features we've added to the app. If you have a smart trainer, or if you have devices like power meters and cadence sensors, or heart rate monitors that communicate via ANT+, you may need additional equipment to allow The Sufferfest Training System to talk to these devices. But first things first:

What are the minimum iPad and iPhone requirements?

iPhone: That iPhone 3 you have sitting in the back of your sock drawer might make you a bit of coin on Antiques Roadshow in 20 years, but it, unfortunately, lacks the guts to handle the full force and fury of The Sufferfest app. If you have an iPhone 4S or newer, you are ready for lift-off. 

iPad: The Sufferfest app plays nicely with iPads from the 3rd generation onward. If your iPad was manufactured after mid-2012 then we predict much mobile Suffering in your future. Need help figuring out what generation iPad you have? Apple has this handy guide

iPod Touch: iPod Touch: the device for people who love iPhones but hate actually talking on the phone. If you plan on using your iPod Touch to help you suffer, we recommend the 5th generation (mid-2013) or newer. Consult this guide from Apple if you need help determining the vintage of your iPod. 

In addition to these minimum hardware requirements, we also recommend installing the most up-to-date version of the iOS software. At the very least, The Sufferfest app requires iOS 9.0. 

What do I need to connect The Sufferfest app to my Bluetooth devices? 

Fitness devices—such as power meters, cadence sensors, and heart rate monitors—can communicate wirelessly with The Sufferfest app using two methods: Bluetooth 4.0 (also called Bluetooth Low Energy or Bluetooth Smart) and ANT+. If your iOS device fulfills the minimum hardware requirements outlined above, it has Bluetooth 4.0 capabilities built in. No additional adapters or equipment is needed. 

iOS devices with Bluetooth 4.0 or higher:

1.  The iPhone 4S, 5, 5C, 5S, 6, 6+, 6S and 6S+

2.  The iPad (3rd and 4th generation models), the iPad Air and iPad Air 2, iPad Mini (1st generation), Mini 2, Mini 3 and Mini 4 and the iPad Pro.

3.  The iPod Touch: 5th and 6th generation.

What do I need to connect the app with my ANT+ devices?

If you have devices that only transmit with Ant+ (no Bluetooth option), then you will need an Ant+ to Bluetooth bridge.  Please see our Connecting Ant+ Devices help article for more information.

  • can i use my iphone 6s to connect to garmin's speed and cadences sensor using strava or mapmyride


    thank you

    forget the hassle with Dongle and Adapter to make the Sensor work for Garmin. 

    Try this one, it has both Protokoll ANT+ and Bluetooth 4.0 LE and both are  working at the same time. So you are able to use it at your Garmin Tracker AND Runtastic, Bikebrain, Stava and so on. The only limitation I've found at my Vivoactive HR is, you have to wait until the sensor is connected to the App at the Tracker, otherwise the cadence is not logged. The Sensor is cheaper as the Dongle and Adaptor mentioned above.

    That's round about 32 Bucks plus international shipping.

    Also the Coospo H6 Heart rate Sensor with BLE and ANT+ is working the same way.

    regards from Germany
