System Requirements

TouchDRO is designed for a dedicated shop tablet. For the best experience (and continued app updates), use a device that still receives Android / Fire OS security updates from the manufacturer.

	Required	Recommended
Android / Fire OS Version	Android 7.0+ (Fire OS 6+)	Still receiving security updates (typically tablets introduced within the last ~2 years)
Screen Size	7" or larger	9" or larger
Screen Resolution	1024×600	1920×1080 or higher
Input	Touch screen or keyboard/mouse ¹	Touch screen
Connectivity	Bluetooth ²	Bluetooth

Android Support and Updates

TouchDRO is actively developed. To comply with Google Play Store and Amazon Appstore security requirements (and to stay compatible with modern Bluetooth stacks and app dependencies), we have to keep the app and its libraries up to date. This means we can only support Android versions for a limited time.

Support window: In practice, TouchDRO can typically support an Android major version for roughly 7–10 years, but the exact timeline depends on Google and the app store requirements.
What happens when support ends: TouchDRO will continue running on your device, but it may stop receiving updates.
Re-installation: Once your device falls below the minimum supported OS version, you may not be able to install/re-install TouchDRO from the app store (for example after a factory reset).

Recommended Devices

Most modern Android tablets (Android 7.0+) and Amazon Fire Tablets (Fire OS 6+) are compatible with TouchDRO as long as they meet the requirements above. For an up-to-date list of known-good tablets, please see the Recommended Android and Fire Tablets page.

1. TouchDRO can be installed on a non-tablet device (a netbook or even Raspberry Pi) running Android 7.0 or later and used with keyboard and mouse.↩

2. Even though the application supports USB connectivity for some USB controllers (such as FTDI RS232), Bluetooth is recommended because it is typically more stable and convenient in shop setups.↩
