The app is only for Xiaxiang bms. And if you have such one and the bms is not visible - make sure there is no other app / device connected to you bms - because as soon an app is connected the bms becomes “invisible”. Let us know ### 3/5 — The pro version is the same as the OVERKILL APP for free *2024-07-22, version 1.3.4* This pro version is the same as the free Overkill Solar app. Don’t waist your money, go get it for free. This app will send you messages through bt if you set up the notifications. ### 1/5 — Unable to set any perameters *2024-07-20* Bought the iOS pro version and it is not usable for any settings. No page settings are available within the app as seen on the app purchasing store page. Total waist of 7.00US. **Developer response:** Hi. Can you explain more detailed your issue? What does it mean setting page are not available? You see all setting whenever you connect to the BMS and press the “settings” button in the bottom right corner. Let me know if this helps or drop an email with screenshots and steps to reproduce to: xiaoxiang@e77code.con. ### 1/5 — Funktioniert mit meiner Startcraft nicht *2024-06-22, version 1.3.4* Gibt es da einen Trick. Batteriename wird erkannt, aber keine Daten ausgelesen ### 1/5 — Ohne Funktion *2024-06-01, version 1.3.4* Ich soll nur Daten Mitteilung einwilligen, aber das die App Grotte schlecht ist, kümmert das keinem. ### 1/5 — Enter PIN1 *2024-02-16, version 1.3.2* Simply cannot get into app. Paid $7.99 and still. I Never set a pin. Waste of money. ### 1/5 — Не работает *2024-02-13, version 1.3.2* Не работает ### 3/5 — Solide App mit einem kleinen „Fehler“ *2023-12-27, version 1.3.2* Funktioniert alles super allerdings gibt es keinen Timeout/standby. Solange die App im Hintergrund aktiv ist, geht besteht auch eine Verbindung bzw. das BMS geht nicht in den Standby Modus (blinkt dauerhaft) ### 2/5 — App bei LIONTRON nicht nutzbar *2023-11-26, version 1.3.2* App bei LIONTRON nicht nutzbar Ordentliche Bewertung daher nicht möglich ! ### 3/5 — Ports können nicht geschaltet werden *2023-09-14, version 1.3.1* Pro Version gekauft um die Batterie (Belluna) an und abschalten zu können leider kommt immer Fehler beim Port umschalten 😐 ### 1/5 — Don’t bother - it’s junk *2023-09-04* With this installed I could never get my BMS to balance the pack. Despite multiple charge cycles, one pack was way higher than the rest and it never improved. I installed “Overkill Solar” which opened up a load of settings (including balancing while not charging) and my pack is now balancing. Maybe the paid version of this app would have allowed that, but I wasn’t interested in paying $15 to open up one setting. **Developer response:** Hi. Setting of balancing option is in the paid settings area. But this is not an reason to give 1 star for the app. Please correct it. Thanks! ### 3/5 — Constantly have to restore purchase *2023-06-24, version 1.3.1* App works great except after paying the $12.99 to access settings, every time I use the app I have to restore purchase to use it. Very annoying and unusable when offline in the bush. Please fix this issue. ### 3/5 — Kein Dual Balance Funktion *2023-06-11, version 1.3.1* Entweder balancieren beim Laden, oder in der Ruhe Zeit. Obwohl beides eingeschaltet, kein balancieren in der Ruhezeit. ### 1/5 — Default Passwort funktioniert nicht bei LIONTRON *2023-06-08, version 1.3.1* Ich habe mit die Pro Version gekauft und damit das Geld zum Fenster Rausgeworfen da das Default Passwort nicht funktioniert und ich so keinen Zugriff auf die Pro Einstellungen bekomme. Ich wäre schön wenn der App Entwickler darauf hinweisen würde das es bei der LIONTRON nicht funktioniert und man nicht seine Kunden so das Geld aus der Tasche zieht…. ## Most critical reviews (10 lowest-rated) ### 1/5 — Doesn’t work never has *2026-03-04* Developer responded lol why? Because your app violates Apple human interface guidelines. It shouldn’t be removed from the App Store entirely. Total trash. Feels like using a virus except a virus actuallly accomplishes something **Developer response:** Hi. Can you please describe the issue more detailed? What does not work for you? How to reproduce your issue? Is the BMS you are connecting to in the list of supported BMS? Please provide more details. ### 1/5 — porn ads *2026-01-19, version 1.3.4* uses their own ad delivery system to advertise porn ### 1/5 — Scam. Avoid all devices from this provider. *2026-01-13, version 1.3.4* This app is used to control a BMS device I paid for. I have used this app for several years to control my device. Now they are demanding payment to setup the BMS. What a scam. I will find a way around, but basically folks avoid any devices that are managed by this company as this is a scam. ### 1/5 — 오류 문제 *2025-09-04, version 1.3.4* 아무것도 변경이 되지 않습니다. ### 1/5 — Пидарасы *2025-07-13, version 1.3.4* В 2020 купил полную версию,все было ок. После не пользовался 2года, а сейчас понадобилось. И что в итоге, опять плати , тупо моя про версия исчезла. Как лоха развели, мудаки. ### 1/5 — Платные функции не работают. *2025-07-09* Ни одна функция в приложении не работают. Даже после покупки. При любом действии выходит ошибка. Абсолютно бесполезное приложение, работает как любое другое бесплатное. Зря купил. Не советую. **Developer response:** Hi. Thank you for the Feedback. There is a warning in In-App purchase screen: do not buy pro if the free version does not work for you. Why have you done this? Anyhow, what is your BMS type you are connecting to? What do you mean with “not working”? Please provide screenshots and how to reproduce details to the support email. Thank you! ### 1/5 — Xiaoxiang BMS Monitor *2024-12-28* Не даёт вариант "загрузить предыдущу совместимую версию" **Developer response:** Apple does not support ios12 anymore. Please update to ios18. ### 1/5 — XiaoXiang *2024-12-28* Нужна старая версия, которая ставится на iOS 12 **Developer response:** Apple does not support ios12 anymore. Please update to ios18. ### 1/5 — Application not work *2024-09-26, version 1.3.4* The application sees the BMS but does not work, what to do ### 1/5 — Would not show data *2024-09-14, version 1.3.4* Download and paid for the app, it recognises my battery name but that’s it! No battery data! Very disappointed! Please refund my £7.99 Thank you ## Most praised reviews (10 highest-rated) ### 5/5 — Time to change *2026-06-01* Hi! Please add a time display when charging, showing how much time needed to complete charge 🙌 ### 5/5 — Funktioniert wie beschrieben *2025-01-14, version 1.3.4* Nach dem Kauf dauert es etwas bis die Freischaltung funktioniert, aber ansonsten alles ok. ### 5/5 — Macht was sie soll *2024-12-02, version 1.3.4* App zeigt alle Daten des BMS an. In meinem Fall eine Alde Batterie. ### 5/5 — Really good! *2024-03-31, version 1.3.2* I have this app because the original app is getting worst each time they update it. So ever since I got this app, its been flawless and worth every penny. Great stuff and thank you! ### 5/5 — Great *2024-03-24, version 1.3.2* Tolle App, vielen Dank, seit Jahren sehr nützlich! Great App, thank you! Very useful and worth the update to premium. The set PIN function could safe me some for hacking problems in the future, I didn’t even know that my LIONTRON (2023) is capable or vulnerable of doing such things. A good feature would be a graph, so that you could see the changes of some values over time. ### 5/5 — Excellent App *2023-05-21, version 1.3.1* Works Flawlessly. Very Happy ### 5/5 — Great app *2023-04-12, version 1.3.1* Been using for many years and more often than not it is accurate and reliable. Recently tried to communicate with FW 61 but the balance options will not save even though there are no errors. It does allow manual balancing though with the new toggle balance switch. OEM software works ok but it cannot overwrite the balance on command from the toggle switch in this app so it must be some kind of master command. Hopefully it will be fixed soon. ### 5/5 — A BMS gem! *2023-04-04, version 1.3.1* This has worked flawlessly for us since 2019!! ### 5/5 — Klasse App und super Support ! *2023-03-12, version 1.3.0* Die App ist wirklich klasse ! Ich habe diese (noch) in der Free-Version und bin begeistert von der App und dem sehr schnellen und klasse Support vom Entwickler, das gibt es nicht oft 👍👍👍. ### 5/5 — Utilizzato con un BMS QUCC *2023-02-10, version 1.2.37* L’applicazione è inizialmente abbastanza difficile da comprendere ma una volta imparato ad usarla funziona perfettamente. Per la parte a pagamento non penso sia un problema spendere 7€ dopo aver comprato un BMS da >100€ e non capisco perché la gente si lamenti. È anche giusto supportare lo sviluppatore che ha creato quest’applicazione. Se non sapete usarla è un problema vostro, non è colpa dello sviluppatore. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
