Frequently asked questions
On the fence? Here are the essentials.
Which controllers is it compatible with?
PlayStation DualSense (PS5), DualSense Edge and DualShock 4 (PS4) controllers over USB and Bluetooth, wireless Xbox controllers detected by Windows (XInput), GameSir Cyclone 2, G7 Pro 8K and K2 8K included, and the Nintendo Switch Pro Controller and Joy-Con are detected automatically. The Valve Steam Controller (2026 and 2015), 8BitDo controllers (in D mode), Flydigi controllers, the SCUF Envision Pro and the MSI Force GC300 are added in one click.
Can it disturb my controller in-game?
No. The software reads the battery in a strictly passive way: it sends no command to the controller. Many tools get this wrong and end up making games “lose” the controller; here it's prevented by design.
How am I warned when the battery is low?
A discreet notification appears in the bottom-right of the screen (Steam-style), with the remaining level, plus a runtime estimate for PlayStation and Nintendo controllers. You choose the threshold, from 5 to 50%, device by device, and a periodic reminder if you want.
Does it work with my mouse or headset too?
Yes. Wireless mice, keyboards and headsets are added in one click from the Devices tab: more than 350 mice, 80 keyboards and 80 headsets are listed, from Logitech, Razer, Corsair, SteelSeries, HyperX, Sony INZONE, Audeze, ASUS ROG and other brands. Each device gets its own icon in the taskbar, with its own alert threshold.
Is there a subscription?
No. It's a one-time purchase at 4,89 €, with no subscription or hidden fees. Version 2.0.20 updates are included.
What do I need to use it?
Windows 10 / 11 (x64). Nothing else to install: everything it needs (including .NET) is bundled into the app. Size: ~60 MB. Interface in English, French, Spanish, Italian, German, Dutch, Arabic, Russian, Hindi, Chinese, Japanese.
How do I receive the software after purchase?
Immediately: a secure download link appears on the confirmation page after payment, and is also sent to you by email.
Is my personal data collected?
The bare minimum. Battery reading happens on your PC, with no account and no tracking. The app only goes online to activate and check your licence, look for updates and, unless you turn them off, send anonymous device reports (model and technical identifiers, never personal data) that help extend compatibility. For the purchase, only your email is used (delivery + receipt), and payment is handled by Stripe. No card data passes through this site.
Are all devices guaranteed to be compatible?
The software is recent and we're actively improving it: we support as many controllers and peripherals as we can, and we expand compatibility with every update, but we can't yet guarantee that 100% of devices work. If yours isn't detected, contact us and we'll do our best to add it.
