Very professional, neat, simple, easy, and basic to use! 🐟

Try to add other languages so people who do not know English can use as well 🪺 Try to add more background colors and settings, I like your peaceful dark settings but I want bright settings as well in your app 🦁 Be the first company in doing what’s good and right 🦇 I appreciate so much how you responded and cared about my feedback 🦁 I really like your bulbs 🐝 I don’t like matte finish as they are depressing to me 🦚 Glossy is better and less depressing 🍂 It was incredibly fun when I was messing around with the colors that the bulbs have!!!! 🍃 I love the quick daylight, blue light and so on settings… 🐎 Maybe you can add quick pure white light in the future! 🐇 Peaceful and filled with joy pure white light! 🦢 The yellowishness of the white light currently is a bit gloomy, negative and depressing 🐈 🐄 Your bulb is around 9.5W each. That means the user has to use 2 bulbs at a times or even more for enough light! 🪵 That will cause a lot of pollutions as more materials are used. Try to make other versions where each bulb is maybe 19W? Try to take survey to see what customers are looking for so they will buy only 1 bulb and it is bright enough for their use 😝 it will reduce a lot of pollutions and so on. Love the peaceful ~dark backgrounds. Allow multiple people to connect to the same bulbs so one family can control with multiple accounts.

Nice set up for inexperienced users

I received this product complimentary for testing purposes. I followed all the directions on first set-up. I made sure my bulbs were less then 40 ft apart. The instructions were very descriptive to follow. I appreciated the labeling of the lights, being able edit and group the lights together or separate. The editing of the lights made it quite easy to figure out which one was being edited with the lights blinking, I especially like that feature and made it helpful to follow overall. I do like the back button during trying to sync the WiFi to the bulbs. When I entered the description of my WiFi it didn’t do a full search of my WiFi until I hit the back button to search. Once I got the WiFi and Bluetooth together set-up it was simple to change the colors and add other features. I liked the guidelines, buttons and easy instructions to follow. Great reminders to follow along the way as well such as, making sure the bulbs are connected to WiFi. Also, the mention of Bluetooth and WiFi on your phone matches the WiFi on the app is helpful as well. One thing I would change, is in the area of the setting or location I would add or make a different color to the “+” (upper right hand corner) when trying to update the setting, it is the same color as the screen, which made it challenging to see. Once my settings, labels WiFi and Bluetooth were all connected, set up of light bulbs was simple to change as well.

User Friendly & Awesome

I received two GE Cync lightbulbs complimentary for testing purposes. The Cync app is very user friendly. The process of setting up the light bulbs that I had received was very easy and the directions were very straightforward. For example, the light bulb that you are setting up will 'blink' and the app will walk you through the process of setting them up, one lightbulb at a time. I had one small issue where the firmware for the lightbulbs failed to update on the first try; however, it worked on the second go. I like that you can really customize the app to make it more personal to you through being able to name things, set custom photos, set schedules, etc. You can also save favorite colors as well. I think that it's neat that you can have multiple 'scenes' with the option of creating a schedule for each. For example, you could have the lightbulbs turn on when you are waking up and have them turn off when you are going to bed. I also think that it's neat that you can use Alexa, Google Home, and/or HomeKit/Siri to configure the lightbulbs as well. I would suggest having the option to customize the colors/brightness of the lightbulbs when you are creating a new scene vs creating one and then having to go back to the home screen to do so. Overall, the app works well and is user friendly. I would recommend it to a friend!
