### 1/5 — Guys…

*2026-08-13, version 20.525*

Hey boys I’m not creating an account just to connect a power meter

### 3/5 — Be patient

*2025-06-25, version 20.525*

So many of the other posted reviews are correct, but the app isn’t as bad as they may lead you to believe.
- There are few instructions on the app. Would like to see something like “turn your chain crank to activate the power meter” or something… Does not connect to the meter reliably
- Why does the app keep telling me I just updated the firmware when that upgrade happened over twenty four hours ago?
- Registering an account using the app is very difficult. Bad entry field prioritization, you will need to start the app multiple times, just so amateurishly designed.
- Purchasing upgrades doesn’t seem to work on iOS once the app takes you to the web site/portal. I had to log in using a computer’s web browser (Firefox) and even then the upgrade store worked like it was written by a ten year old

For such a great power meter, their app and web site is so childishly written/designed.

### 1/5 — Impossible to update PM!

*2025-05-19, version 20.525*

The update doesn’t finish! Now my PM is bricked!

### 1/5 — rubbish

*2025-05-16, version 20.525*

rubbish app

### 2/5 — In spite of..

*2024-11-05, version 20.525*

The quality of the Power2max itself is not in question. The app, which is an important partner to the power meter, lends you to believe otherwise. 

The app works, but 1st do yourself a huge favor and register through the app-portal, not the app itself. The app and the Power2max website have the app-portal pass through. Once you register yourself, you can register your power meter. Then login to the app with your email and password you registered with on the app-portal. I did this and it worked. I was able to update my firmware and even register another power meter. The app seems to work fine now, and though both firmware updates stalled at times, I just killed the app and started over. Also the iPad app seems better than the iPhone app, but the iPhone did install the updates. Good luck.

### 1/5 — Never worked

*2024-11-03, version 20.525*

The app never worked for me and it looks like development has stopped.

### 1/5 — Absolutely do not buy!

*2024-08-03, version 20.525*

Do not buy this power meter! The software is the worst quality. Why do I have to register more than once? Absolutely worthless software!!!

### 5/5 — Einwandfrei

*2024-07-04, version 20.525*

App startet problemlos, nach dem Registrieren vom Powermeter über die Website wie angegeben verbindet sich die App einwandfrei mit dem Powermeter. Gerätedaten (Batteriestatus etc) werden angezeigt, Firmware kann überprüft werden - alles fein.
Upgrade Kauf und Installation wurde noch nicht getestet

### 1/5 — Non funziona

*2024-03-25, version 20.525*

Da iPhone non funziona!!!

### 1/5 — Can’t log in after creating account

*2024-01-19, version 20.525*

I’ve done everything asked. I create an account, password, and username.The app won’t let me login, no matter how many times I try.
