Very expensive kit not fit to use. ### 1/5 — Doesnt connect *2018-06-17, version 2.0* App never finds dosing pump usless ### 1/5 — Funktioniert nicht mit der X4! *2018-04-18, version 2.0* Eine Katastrophe. Seit Monaten kein Support für die X4. Nur die alte App funktioniert. ### 1/5 — Connection *2018-02-17, version 1.8.3* This app continually loses connection to the device. Very disappointed. ## Most critical reviews (10 lowest-rated) ### 1/5 — Terrible app *2020-05-04, version 3.3.2* The app was always hit and miss for if it would connect the dosing pump to my phone or not. Recently it won’t even show up. I reset it and reconnect, it makes the noises that it has connected but the pump won’t show up in app. Would learn how to use it manually and save yourself headaches. ### 1/5 — Still not working *2019-10-12, version 3.2.3* Still not showing my doser when connected manually ### 1/5 — Parou de funcionar *2019-10-08, version 3.2.2* Não está sendo possível conectar à rede WiFi depois da última atualização. ### 1/5 — WON T WORK AFTER IOS 13 *2019-10-07, version 3.2.2* STOP WORKING ### 1/5 — Not connecting ios13 *2019-10-06, version 3.2.2* Was working great. With ios13, app and many other devices aren’t working correctly. Probably more of an apple than a Kamoer issue ### 1/5 — No longer works since 3.2.2 *2019-10-05, version 3.2.2* Latest version 3.2.2 does no longer find my devices and pumps!!! Please help how to downgrade to 3.2.0 again which worked fine. iOS 13.1.2 on iPhone XS ### 1/5 — No connection with 3.2.2 *2019-10-03, version 3.2.2* Since the update to 3.2.2 there is no way to connect the Kamoer X4 pump. Please fix it as soon as possible. ### 1/5 — Kamoer F4 *2019-10-02, version 3.2.2* Seit dem Update auf 3.2.2 keine Verbindung mehr zur Pumpe möglich. ### 1/5 — Not optimised and unreliable *2019-07-05* Not optimised for iPhone XS and does not provide a reliable connection to the dosing pump. Having to reconnect when opening the app each time means the process of making any changes is very frustrating. ### 1/5 — Teure Pumpe - Schlechte Software *2019-04-19, version 3.2* Keine Anpassung ans IPhone X Auto Login nicht möglich... ## Most praised reviews (5 highest-rated) ### 5/5 — Tut was sie soll 👍 *2020-02-15, version 3.3.1* Hab die Dosieranlage seit ca 1 Jahr, die App könnte sicher besser sein aber sie funktioniert sehr gut. ### 5/5 — Easy *2018-12-05, version 3.2* Great dosing unit and an easy to use app Does what it says on the box ### 4/5 — Very poor instructions out of the box *2018-10-18, version 3.1* The app itself is okay, but connecting to the doser is problematic because of its incompatibility to 5g on a router. Although l had my router set to 2.4 and 5g, it wasn’t until l switched off 5g that could find and connect to the pump. Nothing in the instructions to cover this, and in theory it shouldn’t matter. The instructions are in English, but very poorly written, leaving information out and clearly weren’t penned or edited by someone who’s first language is English ### 3/5 — Needs improvement *2019-09-24, version 3.2.1* App needs updating so it sends notifications when solutions are running low ### 2/5 — Needs basic features improving *2023-10-11, version 3.3.4* It’s a very basic app and allows you to set dosing, however some basic things like being able to apply a custom name instead of being stuck with pump 1, pump 2 etc would be very useful… I’ve got two of these units and it would be nice to see what additive is on what head at a glance, rather than having to cross reference a note file… --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
