Now it doesn’t connect to it at all.. ### 1/5 — Doesn’t Work *2018-11-09, version 1.5.19* The Product Doesn’t work Let Alone the App ### 1/5 — Terrible App *2018-08-06, version 1.5.15* I installed the Sylvania Pulse Kit. It took me a while to kit it paired to my phone. The app would constantly crash. I ended up returning the product back to the store. ### 3/5 — Bluetooth keeps disconnecting *2018-05-18, version 1.5.15* The Bluetooth works off and on I can be standing right next to it and it won’t connect sometimes ### 1/5 — Worst app *2018-04-18, version 1.5.15* This app is horrible, have troubles connecting and always freezes on me, not worth the hassle for the lights 👎🏼👎🏼👎🏼 ### 1/5 — Decent product, TERRIBLE app. *2018-03-12, version 1.5.15* (Review re: color headlight stick-ons) This app is a MESS. 1. It will tell you the lights are on when they're not. 2. You have to "Agree" to the terms EVERY time the app launches. 3. It will not remember custom name/settings, so adds another (new, generic name) product to the list every time it launches. 4. When you swipe-left to delete "old versions" (of the same lights), the app crashes immediately every time you hit "Delete"...and so 5. You're forced to scroll down past dozens of useless setups it created in the past each time you launched the app...which you need to do to see if it's even recognizing the unit so you're not changing the color on lights that aren't on (even tho it says they are), plus 6. The Bluetooth will disconnect (act as tho it's connected on the phone while the lights are off) if your car has Bluetooth that you're using for calls or audio. Adding that to the inaccuracy of the color of the lights in relation to the color showing on the phone (ex: purple on phone may look blue from lights, or light blue may look green from lights) – AND the fact that the lights won't even remember their "last on" state – and you've got one DISASTER of an app. It's a shame, because the product is pretty great when it works, and I want desperately to be able to enjoy it – but this app makes the whole thing worth nothing more than a ton of frustration. ### 1/5 — Waste 🚮 *2018-01-22, version 1.5.15* App keeps force closing whenever I select a song ### 2/5 — Issue *2017-12-25, version 1.5.15* Please update the app! It keeps crashing on me and won’t let me change colors. Just stays in the demo mode when it runs on for 10 seconds then shuts off. It says it’s connected but won’t let me do anything. I love your product but needs an update ### 1/5 — Worked for 2 days and won’t connect now *2017-10-12, version 1.5.15* It worked even tho it had trouble connecting. Now it won’t connect, to both my cars (bmw m3 and 370z nismo). ### 1/5 — No se conecta... *2017-06-17, version 1.5.15* Tienen soporte en "español" ? La aplicación nunca se conecta. ### 1/5 — Bug *2017-02-19, version 1.5.15* Sometimes it works fine and the other time it doesn't work ### 2/5 — App is ok, not great, and has bugs. *2017-01-30, version 1.5.15* The color wheel works, but the patterns are not labeled properly. The buttons don't actually represent what the pattern is. This app also works with music, which is good, except you can pause the music, you can't skip to the next song, you can't do anything except load songs and play. If they had a built in player, it would be way better, or let you use iHeartRadio. Sometimes when I try to use music, the lights don't come on at all, and I have to restart the app. ### 2/5 — Won't connect *2016-10-15, version 1.5.15* Worked really good till a week ago and now won't connect. ### 2/5 — Won't connect *2016-08-29, version 1.5.15* Great product. Worked fine until a few days ago. Now won't connect to lights. Finds my lights but won't connect. ### 1/5 — Great but freezes my iPhone *2016-06-24, version 1.5.10* Great app but it freezes my iPhone! PLEASE FIX ### 1/5 — Zevo *2016-06-10, version 1.5.10* The lights are great but the app keeps crashing and freezing my iPhone which makes me so mad that I bought a product that I can't use anytime I have the app open for more than two minuets it completely shuts down my phone which causes me not to be able to use the lights that I bought I wish you would fix the problem so I could give y'all five out of five stars for the review please fix before I have to return the lights for a refund and not recommend your product due to the app freezing and or crashing ## Most critical reviews (10 lowest-rated) ### 1/5 — Absolutely junk *2020-12-23, version 1.5.19* Ever since I bought this piece of sh__ kit it either never finds my pulse kit or it connects and you can’t do anything so this is the absolute worst 60 dollars I’ve ever spent and they never will update the app ### 1/5 — Had these for years *2020-07-24, version 1.5.19* I have had these lights for years and now they will not connect to my app anymore. I have tried two different phones one new and one older and still nothing. Very disappointed because these lights were not cheap. Don’t think I got my money’s worth out of them. Update the app or stop selling these lights because that’s a lot of bull crap for 60 bucks. Don’t waste your money. ### 1/5 — No se conecta, MIERD4 *2020-06-14, version 1.5.19* Es una basura ### 1/5 — iPhone 11. Over heating? *2020-05-08, version 1.5.19* When app is in use I phone is over heating. ### 1/5 — How do I get it to work *2020-01-09, version 1.5.19* Lights in but no devices are coming up ### 1/5 — Fix app. Update made it worse *2019-11-05, version 1.5.19* This app was great until I got a new phone (upgraded to the iPhone X) the color is too zoomed in where I cannot select the colors on the side. Please fix ### 1/5 — The app is horrible *2019-04-27, version 1.5.19* No support for the app whatsoever, if finds the lights and connects to them but nothing happens. It says the lights are on but they are actually off. App constantly crashes. ### 1/5 — Good product terrible app *2019-03-05, version 1.5.19* The app shuts off the lights randomly and it really doesn’t allow for as much personality I have seen in other products on the market. The product is capable but this app holds it back. ### 1/5 — Unable to reconnect bluetooth *2019-01-13, version 1.5.19* The app and product was working fine when I bought the car. Up until I unhooked the car battery to wire my sound system, the app stopped working. I can’t turn the lights off, change the colors etc. The device is no longer connecting. I’ve uninstalled/reinstalled the app, ensured my Bluetooth is on etc. ### 1/5 — Not working *2019-01-07, version 1.5.19* Omg, i cant even connect to my lights!! It just doesnt appear, faaaaaackkkk ## Most praised reviews (10 highest-rated) ### 5/5 — Great! *2016-09-29, version 1.5.15* Solid app! ### 5/5 — Spectacular *2016-07-01, version 1.5.15* Awesome app and product! Works great and great quality of colors. I would love to have a further connection range on the next update. Just so I can turn them on from across the parking lot. ### 5/5 — Love the App; Thanks for updating! *2016-06-25, version 1.5.15* Recently installed the pulse lights to my Kia Soul, and they're just simply dazzling. Even though I do not drive with them on, I enjoy receiving the showy flourish of attention whenever they are on. However, since I attached my Pulse lights to the ACC, where they only turn on when the engine starts, could there be an option to customize how the lights react to turning on the first time? (Such as, the demo button on the packaging that rotates through all the colors for about ten seconds and shut off) Nonetheless, the lights are a blast, and the app appears to receive updates unlike other LED apps; worth every penny! ### 5/5 — New update fixed bug issues! *2016-04-10, version 1.5.10* I love the features of the new update, thanks for fixing the issues! ### 5/5 — Please add a color cycle mode please! *2016-01-02, version 1.0.4* I love this app. It works flawlessly with my zevo pulse. Very responsive but I agree with everyone else. Please add a option to automatically cycle through the colors and maybe fade in and out slowly to each color. Other than that the zevo pulse works great on the car and installation was a quick process. No problems connecting the app to the car either. ### 5/5 — COLOR CYCLE MODE *2015-11-30, version 1.0.4* Everything on this app is perfect in my opinion, the only downfall is not being able to have the colors cycle automatically, would love to have this mode to display at car shows! ### 5/5 — Add color cycle mode! *2015-10-06, version 1.0.4* Add color cycle mode great product tho reliable for sure! But need color cycle ### 4/5 — Love the new update *2016-03-31, version 1.5.9* The new features are amazing but it crashes my iPhone 5s when I click on my saved colors ### 4/5 — Needs some bug fixing *2016-03-30, version 1.5.9* So glad it got an update! Love the new features! Only thing when you try to click your saved color it kicks you out, if you can fix that bug that'd be great! ### 4/5 — Add advanced color control! *2016-01-18, version 1.0.4* The app works very well for single color choosing and audio sync (whether it's library or mic). PLEASE add the ability to do a color blended color cycle, or hard cycle. EVEN better, add custom routines. Something like the Philips Hue control "Lightbow" would be great. Even the ability to strobe a color would be awesome. I feel the hardware has some real untapped potential. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
