Firefly App 2.1 Highlights

A much wider selection of temperatures
From 6 pre-set temperatures in the old app to 31 pre-sets in the new app (200-500°F by 10°F increments, or 5°C increments if you prefer celsius).

A streamlined app experience
Connecting the app to the Firefly 2 has been integrated with the primary temperature control to get to the main activity more quickly. The slider is also more attractive and fun to use than the previous temperature selector.

A simplified "ready" indication
The LED now pulses twice and turns solid green after a 3 second pre-heat the same way every time. This reduces ambiguity about when to start your draw. Start as soon as the LED turns solid green every time for the most consistent performance. We like to call it "LED, count to 3."

A quicker draw
What used to take 10 seconds of inhalation time should now take about 7-8 seconds with the new firmware, requiring less effort for the same results. This is accomplished by increasing the power of the pre-heating stage and giving a more consistent indication to the user about when to start their draw. You can still start your draw any time you like of course, but for best results start as soon as the LED turns solid green.

Setting the temperature directly without the app
Choose from 7 settings directly from the Firefly 2 (320, 340, 360, 380, 400, 420, 500°F)

Battery status not accessible, but

*** update ***
So it has been almost one year since my last update. They have issued an update to the app to add more features, thankfully these are all accessible with voiceover! However, the original complaint I had about the battery status not showing for voiceover users has not been addressed.
Call me a whiner, but if you issue and update you could at least address the bug that has been reported to you a year ago. The battery level is kind of important to me. I think most people would agree that they would like access to know how much battery they have left!
Of course this only applies for people with visual impairments, if you have no visual impairment Vape away!
All the other features are nice. If the battery level was accessible with voice over, this app would have received five stars. Hopefully they will update soon, they were notified of the issue in January 2017.

Loyal Fan with some issues

Let me start off by saying that this has nothing to do with the unit itself, just the app.

I’ve been using the firefly2 since launch (preordered) and have been able to see the changes and improvements with the app and firmware over time. I do like the new app, though it took forever to get it while the old one was down (I actually called Valerie and told her about the patch!).

Of the few problems I have with it, one major one is the lag time it takes to connect the firefly to the app. Maybe it’s just me, but on the old app it worked much faster. It also takes a while to open the app by watching the cutscene logo and then getting to connect. The whole process takes about 25-30 seconds which doesn’t seem much, but when trying to just adjust quick it makes it difficult. My left bumper has been bum from the start and I can’t do the button temp change, so I need to go into the app. I don’t think that would necessarily work so well either though.

If the app just worked a bit faster and maybe had a few more tips in it (really proper cleaning like not damaging the lid adhesive and whatnot), I think it’d be great. I hope this gets read, love y’all!

It’s OK- need to fix issue

Nice looking app, does what it needs to do. Giving 3 stars however because it seems like almost every time you get out of the app you have to reconnect the device which requires pushing the touch buttons again and the whole process takes a while and annoying to do so many times. The old app never used to do this- not even when changing batteries! It used to auto detect... they made the app look better and apart from the custom temp controls, made it function worse
