Do your homework and it works well

As most reviewers have said there are several possible problems with using this app. If you do your homework, that is read all the negative reviews and watch the you tube videos you can skip all the headaches. I’m not the most tech savvy guy, but after reading all the feedback I didn’t have a single problem getting everything to work as advertised. As mentioned in other reviews install the EW-WU111 and then up date all the firmware through the battery charger connected to a PC with E-Tube installed. Then I used the E tube app on my IPhone to customize everything. When done with the app be sure and disconnect it from Bluetooth and you will be good to go

Works great for me.

The factory default mode for Shimano's e8000 e-bike drive unit has TRAIL set to LOW and BOOST set to HIGH. This didn't work for me at all. After installing and registering, the app Bluetoothed my bike before I even powered it on. Pairing was seamless. Changing to the other preset profile which increases assist in TRAIL and decreases assist in BOOST was bonehead simple. There are still a couple of tweaks I can do if this adjustment leaves anything to be desired. The app works perfectly for what I need it to do, and the price is right.

No longer the worst, but close

This app used to be the worst iOS app out there. Now it is no worse than the third worst. My current issue, with v 4.0.2, is that it will connect to the Bluetooth module and detect an update is available. But the "Update all" button is disabled, and I can’t get it to update. And Shimano has no support. Unfortunately, it can’t connect to my Garmin, and the first thing Garmin says do is update the firmware. So no joy.

It used to be even worse. The appearance has improved, and the organization is somewhat more logical. But it still can’t maintain connections, and can disable your di2 bike. As at least two reviews say, if it disables your shifting, unplug all your devices, wait a bit, and plug them back in. I’ve been able to get my bike working again by unplugging the Bluetooth module and both derailleurs, without messing with the shifters.
