Napoleon’s eFIRE app will revolutionize the way you use your fireplace. The first fireplace to be controlled by Bluetooth, using an app on your smartphone. As soon as you launch the app, it’s startlingly easy to use. The intuitive interface knows just what you want, and with easy toggle sliders you can control everything on your fireplace from the flame height, blower to LED lights. Imagine having total control of a room’s ambiance with just a couple of gestures. Full mastery of your ember bed allows you to create every imaginable color, selecting the one that fits the mood, or the décor with ease, the simple color wheel tool swiftly scrolls through the colors. Or set the mood with one touch. Ember Bed Mode instantly creates ambiance with the look of a banked fire, softly glowing. Get the atmosphere without the heat, you can even cycle through, and set the color without the fire even being on. Additionally the Napoleon’s eFIRE app has all of the same functions as a traditional fireplace remote; by controlling ON/OFF, flame height and blower speed. Now you can personalize the experience with your smartphone by controlling the following options - Flame height - Blower speed (if equipped) - 24hr Auto OFF timer - LED Multi color Lights providing over 16,000,000 different colors - LED color wheel to pick any color - LED cycle mode to cycle between the most vibrant Red, green and blue colors - LED Emberbed mode which best represents a real burning Ember bed - Quick access to multiple fireplaces equipped with Napoleon Bluetooth - Accent Night Light control - Split flow valve control - Auxiliary Contact control - Continuous pilot control 7 Day on demand pilot feature that will automatically turn off the main burner and keep the pilot active if there is no activity from the controller for 24hrs. The pilot will remain active for 7 days then turn off if there is no activity from the user or no call for heat. This new feature will help save fuel consumption and save on operational costs. The New Auxiliary Contact Control feature on the app lets the user know if the Fireplace is being controlled by another device. For safety reasons the fireplace can only be controlled by 1 device at a time and the remote that comes with the fireplace will have priority over the Bluetooth control.

Verdict
The clearest difference is rating: Sub at 4.4 against eFire's 1.0. Sub also leads on update cadence (every 5 weeks vs every 8 months) and ratings volume (788 vs 2). eFire's advantage is monetization model (free vs ad-supported) and iOS requirement (8.0 vs 15.5). On price, ads and in-app purchases there is nothing between them.
