Realtime Charts is a free, easy-to-use, and highly interactive application for Android devices that allows you to graph multiple engine sensor data simultaneously. You can create multiple graphs for a single engine, or for all engines on your vehicle.

You can add multiple sensors, specify the sampling frequency, set different ranges for each sensor, and set different chart attributes.

In addition, you can share your charts with other users, or with the public, through email or social media.

Realtime Charts is the perfect tool for the automotive hobbyist, professional or DIY mechanic who wants to monitor, tune, diagnose or analyze their vehicle's performance.
