Helps me stay safe

I recently moved into a building that has ButterflyMX. I hadn't heard of ButterflyMX before, but I am sooooo grateful to have it. I have underlying conditions that make me more susceptible to Covid-19 and I go out of my way to avoid touching things. With ButterflyMX, I can open the door of my building using the app on my iphone. I also just discovered a way to do this via Siri. I set it up so all I have to do is say to siri "open door," and the door magically opens. I don't have to touch anything.

The other thing I appreciate is that when deliveries come (I order food a lot), I can see the delivery person through the mobile app and can let them in. In my old apartment, I had to walk to the kitchen and speak into the intercom system that was on my wall. Now I can do it from my phone. It doesn't seem like a big difference, but it actually is very useful.

The last thing worth mentioning is that the ButterflyMX customer service team is awesome. When I moved in, I wanted to make some small customizations. So I found the ButterflyMX phone number and just called. The customer service team walked me through all the steps to make the necessary changes. Was super easy and they were so friendly.

I really like this app, especially during this crazy time we are living in.

Next level convenience

My building just introduced the ButterflyMX service and I was in immediate disbelief that I ever functioned in NYC apartments without it. The app allows you to create ‘virtual keys’ for preapproved visitors, so I created one for my dog walker who comes every weekday around lunchtime. Now he enters the building without having to buzz a bunch of my neighbors’ units until someone lets him in. We also have a key fob on our elevator, so when I ordered seamless I’d have to go downstairs to grab my food. But somehow ButterlyMX unlocks the elevator for the delivery guy to only get to my floor, so I no longer have to go down to the lobby to grab my deliveries. Incredible convenience! Mobile app is great too!

Terrible & unusable

I gave 1 star out of five because that was the lowest. If I could choose, 1 out of a 1000. I really, really dislike this app - it’s usability is 0. Great idea, really great. Execution - terrible.

I don’t know why but we’ve missed all calls - the delivery person just quits. The sound starts, the phone locks and the slider is as easy to use as opening a can with oily fingers. It just slides all over the place. I have to go down and rescue every poor soul locked in our building. I can’t imagine an app so poorly designed for its one function. I mean a 100% failure rate, there’s no signs given by the company offering instructions. The app doesn’t need high quality video (if that’s what’s killing its startup time)

This is great idea and if they executed 10% it would be almost usable. Disappointing at how companies can make such awful decisions while acting in the pretenders of looking after the customer. Or, clearly, not even knowing who the customer is.
