SunSprite Wearable Light Tracker

This is amazing! When it says 100% full, I have learned that it's half of what I need, so I leave it on. (seasonal affective disorder) After that initial 100%, the only way to know how much light I'm getting is to bluetooth it to my cell phone app, and it gives me a more detailed readout. When it reaches 200%, I'm good. If it goes higher, I know I'm getting a bonus.Update April 2019: it broke. New one arrived but would not sync with my Galaxy S7 phone (the old one did). Manufacturer sent a new one, had me try different things. It would not connect either. Now I am without. :(

I agree with whomever said "Save your money." Did not work for me. I went through 2 of these. Talked to the company office. They were very nice (emailed first,; they called me) Followed the directions. Both quit after a few days. I was told to put it in a bright window or outside to recharge (it says that you don't have to recharge). I did this. I was happy. Only worked for a day or so. I bought it to use with a light therapy to make sure I was getting enough from the Lamp - Day-light Sky--which has been excellent. I thought it was a great idea. I found it under a review for Day-light sky. the reviewer really liked the SunSprite. Disappointed that neither worked. Thanks to Amazon for the refund. I am not sure I would recommend. It is very delicate and seems over-priced. Maybe you will be lucky. If you get it, make sure you decide soon if it works so you can get the refund.

So it was working well, syncing with the app wasn't so smooth but my issue is that the housing broke, and not from dropping it either. I was wearing it on my sleeve when I heard something fall on the floor. I looked and I see the plastic front face. Not sure what to do with the thing now.

Most people don't get nearly enough sunlight, for our health. Mostly out of fear of melanoma. However other benefits of sunlight outweigh that downside, and there is artificial light we can use too. This tracks a healthy amount.

I've been wearing this every day for about five days now. Even if I turn off Bluetooth on my phone it remembers all the readings for that day, as shown once I sync the two later in the evening. It reads the current luminosity every minute, as can be seen in the companion app if you use two fingers to spread out the time chart on the history tab.This product could be reviewed alone, since it does tell you without the use of an app what percentage of sunlight you've gotten that day. But in my opinion it needs to be reviewed in conjunction with it's app. The app is well written and easy to understand. It doesn't crash and I haven't had any problems with it. I have a couple of minor areas in which the device and the app could be improved. For one, the battery in the device doesn't hold a charge for long enough. This only shows itself, however, if you try and display the current light level in the morning before the device has been exposed to sunlight, enabling it to recharge. Also, sometimes I forget to put the device on my lapel, resulting in inaccurate readings. Either I left the device in the shade while I was in the sun, or left the device in the sun while I was in the shade. In either case there's no way to set the percentage in the app to 0% for that day. You can do so for the device by disconnecting it from the app and re-connecting it, which will enable you to see your percentage for that day accurately on the device only. The device is a little larger than I would like, and unless I connect it to my lapel or V-neck vertically, it sometimes turns my collar over, resulting in the device not being fully exposed to sunlight. I also ask myself just how dorky I look while wearing it. And there are conditions where the device will be in sunlight but my face won't be, such as when I'm driving in the evening towards the west. Since the science behind the device states that it's the amount of sunlight that arrives in your eyes, that would result in an in accurate representation of how much sunlight you received. I would also prefer that the gamification in the app include motivations to gather sunlight in those first two hours of the morning after your ideal wake up time. These are the hours that are displayed in the dark green in the timeline in the app. Lastly, once I've gathered a week or so's worth of data, I wonder if it's really worth the effort to keep wearing the device, since I then have a good idea about how much sunlight I get in my normal routine. But spending $100 to get that idea is worth it to me. Also, I'm considering buying the company's sunlight lamp, which would then considerably extend the usefulness of this device for me.But these are all relatively minor issues and mostly just improvement suggestions, and not enough to be considered as being compromising of the device's or the app's quality.

I've been watching this device for well over a year, and gearing up for some sleep hacking with the new year, decided to go ahead and get it. I've only had it for a day, but I'm already pleased with it. After going for a walk in the late afternoon it reflected what light exposure I would have expected.Testing it on a light therapy lamp, it showed that the lamp was basically useless beyond the tested range of 10 inches. If the battery is low it will throw some bluetooth errors in the app as the bluetooth will kill the battery, but the app just sees this as an error, so battery level reporting would be nice.The price for this device is kinda high, but if you're dealing with sleep issues it just might be worth it. It is for me.
