Awesome for key-fobbed elevators

We have key-fobbed elevators in our building, which used to mean that whenever I had visitors over I would have to go down to our lobby to meet them. Since we installed ButterflyMX, whenever I grant access to our building the elevator to my floor is temporarily unlocked - allowing my guests to make it up to my apartment without me going downstairs. What's even cooler, all virtual keys that I issue to my friends or family unlock the elevator too. It has made living in my building so much more convenient. I love this product and use it every day.

Almost there

There needs to be a key pad on the box and a number associated with your phone for deliveries. For some reason delivery people really struggle or just don’t want to take the time. They have to click directory then scroll to the first letter of your last name and find your unit number/name... the new feature adds the ability to open the door directly through the app which is better, but the delivery driver has to call you directly, then you have to open the app and unlock the front door (in Chicago in the cold weather he has to take off his gloves, pull out his phone while holding the box/food and dial a number)’s still not as efficient or easy as being able to type in 3-4 numbers with one hand on a keypad and selecting 9 to open. Not sure why this isn’t a simple option...all these features are being added are great and love the virtual key options, video, but 99.9% of the time I just need quick entry for deliveries and I’m having to go down to the front door way too often. Basically, it adds a lot of great features to the call box experience but misses for typical daily use.. maybe I order on grubhub way too much

Inconsistent and Difficult

This app is possibly the most frustrating development in technological history. Conceptually it’s great, but in practice, it’s a headache. The touch screen is not intuitive so deliveries and guests often give up and call me. Then, because theres no way to remotely open the door without getting called on ButterflyMX, I have to stop what I’m doing and go down to the lobby to let them in. And if it’s a package, forget it, they’ll be back on the truck by the time you get downstairs. A feature that allows you to open the front door unprompted is essential. Also, when you do get a call on ButterflyMX all your devices start lighting up like a Parade and don’t stop even if you let someone in on one of the apps. God forbid you’re in a meeting with your phone and iPad, you’ve got to go digging in your bag to make it stop. While I believe this type of technology is the future, the past systems are still superior to this dreck.

Developer Response ,

Hi Shecky Greene, thanks for the feedback. We are in the testing phases for the 'Open Door' feature in the app, it will be available soon! Please email our support team ( with details on the building and we are more than happy to find a resolution for any issue.
