Hilariously bad

Guys, come on. It's 2021, how is an app this bad. So many bugs for an app with admittedly a very bare bones setup - sleep timer never works, light dimmer likes to just spike up to max brightness sometimes when adjusting, sometimes the color adjuster doesn't even match the color being shown off by the lamp.

For a company that focuses on gear made modern, I think they captured the wrong side of modern. Giving three stars since at least the lamp works very well.

Can’t get true red light via app = frustrating

One of the things that attracted me to the Lander Boulder lantern was the app’s capability to change the lantern’s colors, especially to be able to keep it on red light at night. I just tried it out, and unfortunately, I’m not able to get the lantern to show a true red color via the app. The only way I’m able to get to a truly red color is by manually clicking the button on the lantern, which is frustrating. Every time I try to swipe to the red color in the app, it is only able to go from purple to pink to light orange, completely bypassing a fully red color. Don’t know what this is about, but hopefully it will be fixed in a future update. The color selected in the app also is a bit off from the color actually being displayed on the device.

That being said, it is nice to have the ability to turn the device on and off, dim or increase light, etc.. Haven’t tried the sleep timer yet, but hoping that will work well.

One improvement I’d like to see too is a mode to continuously cycle through through all colors or a selection of them like other RGB devices have the capability of. Also, perhaps a “red light only” mode to easily toggle would be helpful. I still have hopes that this product can be improved, and I’ll update my review when it is. Also, being able to change strobe speed (music mode too?) would be nice.

Super Intuitive

I used this on the Cairn XL. It was incredibly simple to set up and then was packed with features I didn’t expect. It can change the light depending on how far away you are. There is a battery saver option that turns off the light if you walk away, and back on when you return. Super simple, sleek, and useful.
