Had to search for the KA version. Qr codes on unit went somewhere else.? App logo on moto G5 reads. KA. for me KG110. Unit fount it quick. No pair code needed, does not need Bluetooth action. Now works great at 30 ft away . Ebay 29 clams

This app works pretty good and has great information and a good UI. It has some issues. 1. It seems to always report 100% charge regardless, and changing the maximum voltage doesn't change it. 2. The calibration setting isn't intuitive and when you find it it's only whole numbers of a percentage, 99%, 100%, etc. This isn't enough resolution to finally tune 4 digits to calibration. 3. If it does not record total Watts of charge or discharge. 4. If the chart doesn't show trends easily.

Very useful app. Would be more useful if there were adequate documentation. REMARKABLE number of ways to modify the measurement environment, scale current and voltage displays. Probably more sophisticated than most users would want. The size of a phone screen makes things a little awkward at times (e.g. for setting scales). It would benefit from having colors of graphs tied to color of the appropriate axes somehow. Certainly complements the display panel that forms the front of the device.
★★☆☆☆
Notification disabled, can't turn ofg no matter what device I use
★★☆☆☆
After updating firmware the app has a continuous "loading" spinner until you press back, and then you can't change any settings. Have reinstalled the app and factory reset the meter. Does the app (1.4.2) need updating to match the firmware (version not displayed but updated on 20250927)?
★★☆☆☆
Contains malware called Digoxin! Forbidden by google but for some reason this apk still available in google play! This app is full of chinese spyware. Beware!
★★☆☆☆
Blue tooth is only good for 10 feet. Wants to know your precise location which IMHO it doesn't need but only to spy on you.
★★☆☆☆
App has notifications blocked and the option to allow them is grayed out. It freezes frequently, and you need to force it closed and restart, and lastly 80% of the time it says "Connected" but fails to load any data and immediately disconnects saying "Disconnected, try again". Useful when it works but very unreliable and annoying.
