I need to use with my dash cam ### 1/5 — Stop working with few month *2023-01-03, version 4.50* This is the worst device I have every encountered. To begin with, app stopped working after a few month, and without the app, might as well rip out entire device since you can’t view any record. Please don’t waste your time to even consider this device….. absolute waste of time. Ps, you many ask, is there a customer service? No, none, zero, so, go figure. ### 1/5 — Bad service *2022-08-16, version 4.50* This app only worked for me for the first few weeks after purchase. I’ve had the car for 3 years now and it never worked since. The few occasions I needed it, I could not use it. It always says there is a new version but it never actually updates the app. Would never recommend this to anyone. Pure waste of a lot of money. ### 3/5 — Wifi *2021-11-12, version 4.50* Hey guys connect it when you are near to dash cam. It is not really wifi connection I would say more like Bluetooth. Remember you are connecting to dash cam not, wifi internet. ### 1/5 — And the verdict is *2021-09-20, version 4.50* What a load of junk. You’d get better stuff from a rubbish tip. On top of it you cannot get new parts for it. STAY AWAY. ### 1/5 — another app available *2021-09-16, version 4.50* Rubbish app it does not connect with my cameras so how do I go about connecting with my cameras is there another app available similar to e-FOCUS it’s frustrating it won’t even update what sort of app is this 😡😡 ### 1/5 — Absolute Garbage *2021-05-15* This app is utterly unusable. There is absolutely no support whatsoever and it’s absolute garbage. It was SUCH waste of money to buy this dash cam and its blackbox. It was usable TWICE, then it has been unusable ever since. ### 2/5 — Can not connect to wifi *2021-02-06, version 4.50* The same happened to me, just connect about 1 second then turn off ### 1/5 — Doesn’t work *2021-01-04, version 4.50* App never worked once. I keep getting a jot of stink to update and when I click it it takes me to the App Store and there is no update available ? Very poor would not recommend ### 1/5 — Buy something that works *2020-12-23, version 4.50* Ditto everyone else’s 1 star ratings ## Frequently asked questions about eFOCUS ### What can I do with the eFOCUS app?
