I previously reviewed I couldn’t register the vehicle. Turns out as it was a dealer demo the dealer hadn’t unregistered from the previous driver. Smart had to get involved and took several days. Once this was sorted registering on here was straightforward and more stable than the official smart app.
Developer Response
Hello # is a 3rd party app. It’s not the official one. We would not be allowed to collect your personal data necessary when you register. You will have to register with the official app, after that you can use the same password in hello #. We don’t collect any data and hello # connects directly to official servers from smart. The credentials will stays in your phone only.
4/5 – Great app, but missing Wallet/Apple Car Key support
Vasco Barreiros
The app works well and is essential for interacting with my Smart #5. However, I’d really love to see support for Apple Wallet / Apple Car Key added in a future update.Being able to unlock and start the car using my iPhone or Apple Watch (just like I do with payments or hotel keys) would make the experience even more seamless, especially when I don’t want to carry the NFC card or my phone is deep in a bag. Other brands are beginning to support this, and Smart should definitely be among them.Please consider adding this functionality — it would be a major upgrade for iOS users!
Impressive App

I downloaded this after issues with the official app. The set up was so much easier and it’s more user friendly with better features. Thanks - I’ll definitely buy you a coffee!
Excellent

Excellent app .. almost perfect .. so much more useful than the official Hello Smart app .. the only item on my wish list would be the ability to view charging history .. with that added I’d give it 6 stars! ..
