Used to work pretty well. Not compatible with current Android OS. Note- there is a new Lenz app in the play store! Search for "Lenz app", it replaces this older app. It works and so far seems like an improvement over the old app.
Was great until the new Android update. Please get a patch out!!!!
Not compatible with Android 10 so now I'm stuck with no app to control my $300 socks. Wonderful.
The app does not work with my heated socks; the bluetooth function does not find the battery packs.
terrible. does not work.
Socks easy to control with phone once paired correctly. Have charged and used batteries once. Upon disconnection from the charger and connection to socks, one battery was at 60%, the other at 67%. I got almost two hours before one battery died, with settings of 1-5 as my toes got progressively colder (-10 deg C). Hopefully the storage capacity will improve with further charge/discharge cycles.
Garbage. Requests permissions it doesn't need (files + media), dialogs are only in German, controls are often obscured by other UI elements - just no good.
Why would a manufacturer make an app and product so complicated. It doesn't pair, at least not in the typically simple way, the flashing empties battery with no way to shut it off, and is overall user unfriendly.
This app is functionally useless. It linked to my batteries once then lost the connection and I cannot reconnect. Tried deleting the batteries and re-syncing, tried uninstalling the app and re-installing. Tried to install an automatic update which would not install. Not only is it an insult to force you to buy a $5 app to get full functionality from a PREMIUM product but the app absolutely stinks. If you are considering buying Lenz heated socks so that you will have the functionality this app is supposed to provide, don't bother. I already returned one pair of socks thinking that the problem with the app was a problem with the bluetooth units in the battery packs but a second pair also performed the same. I'm using an Android 7.0 phone so maybe it will work on iphones?? Customer service is non-existent. The socks work great but you will have to use the manual buttons to control the heat and remaining battery life will remain a mystery. Truly pathetic.
App doesn't add much value. I returned the socks (not that great) but they got me for app anyway.
