Hit and miss, usually miss

So, I have 2 4iii power meters on 2 bikes. The app seems only to be able to recognise one at a time even though my Garmin can find them both. This has led me on quite a wild goose chase believing the meters were faulty. Really poor.

Funktioniert

Nutze einen Powermeter und bin zufrieden. Alles funktioniert. Kalibrieren, Batteriestatus, Update. Alles gut

Aggravatingly buggy

Fields keep clearing themselves after filling them out and the bikeindex.org integration doesn’t support adding a power meter to an existing bike.

Could not connect

For the first time the app could connect my powermeter. But later my device connection became inactive. I tried removing old connection and pair it from the scratch but the app cannot find my powermeter

Schlecht.

Hab an meinem Cube Nuroad C:62 Race werksmässig den einseitigen 4iiii Precision 3+ Powermeter.
Dieser zeigt leider in der App nur ganz komische Daten. Zum Beispiel wird die Geschwindigkeit oft falsch angezeigt.
Ich würde den Hersteller hiermit bitten dieses Problem zu lösen.

Müll

Diese App ist der größte Müll.
Schon bei der Anmeldung löscht es dir Daten aus den Feldern und erkennt den/die Powermeter nicht automatisch.

Non serve a niente 😂😂😂

Un disastro totale ….non si collega mai…e non capisco perché non intervenite a spiegare a chi li vendendo come funziona..ripeto un vero disastro..

Will not connect

HRM links to Zwift and other apps. But will not link to this. In fact the screenshot of this app are different to what is available and what is described in the HRM manual.

Can’t find power meters that Garmin finds instantly

This is on multiple power meters

wahoo can find powermeter this app cant

wahoo can find powermeter this app cant

App won’t recognise two heart rate monitor devices

Ended up with a second heart rate monitor after I thought the first was broken (which it turns out it wasn't). Took me a while to realise the app was the problem rather than an issue with the second unit.

Have to manage second unit via another phone using a fresh copy of the app. Other iOS apps recognise both monitors concurrently (as long as don’t reach the Bluetooth limit).

Hope this helps somebody.

Offset never works

The app has terrible connection issues sometimes can sense the right side sometimes the left side extremely irritating. I cant believe Shimano associated with such low quality product .

Idioma

Funciona correcto, pero una posible mejora sería que estuviera en español

Unbrauchbar

Ich kann es nicht nachvollziehen, warum es nach Jahren der Nutzung noch immer nicht möglich ist, mehr als ein Powermeter in der App per Bluetooth anzumelden! Wird die App überhaupt gepflegt?

Used to work

It seems to do nothing now. My bike computer headsets all see the different 4iiii cranks I use so I’m not wholly out of luck. But firmware scans and updates are apparently no longer an option. Seems likely it is abandoned as a software solution. Consider another product.

Basics are ok, bike index integration laughable

This app finds my power meter without issue and the battery meter works as expected. The zero offset calibration seems to work well but there is no indication of an offset number so it is hard to tell if it is reasonable or consistent.
The link to bike index for me was laughable, worst I have seen in a long time. I entered my bike on the bike index website but linking the power meter to the bike via the app was beyond unstable, the bike would disappear, all entered text would disappear. I gave up after 5 tries, all with the same result.
I haven’t seen a firmware update yet so I can’t comment on that functionality.

Worst app

Simply does not work

Bad App

How can the 4iiii Powermeter connect better with Garmin than with the own App?

Sort this out.

App doesn’t pair to power meter. I know it’s working as head unit can pick it up. Pretty poor.

Will not connect

Whilst the belt connects to my iPhone it will not detect in the app. Used to be great but now woefully inadequate and outdated. Avoid and find something else.
