Sensor Charts is a powerful tool able to record automatically in background all sensors data and render it at your command in wonderful and colorful charts.
What was the day of August when the cell phone boiled with a stratospheric battery temperature? With Sensor Charts any data from your sensors like this will be within your reach simply and effectively.

It supports several sensor types (multitool)*:

☁️ Pressure sensor
🛳️ Magnetometer
💡 Light sensor
⚡️ Battery
⚡️ Battery Temperature
⚡️ Battery Voltage
🚀 Proximity sensor
📱 Memory (Free)
📱 RAM (Free)
⛳️Compass
🏃 Step Counter
🌞 Screen Brightness


Sensor Charts will show you:

🌟 time ranges in pie charts (to answer questions like: how long has your screen been turned off in the current month?)

🌟 historic sensor data by day and month in linear charts. You can zoom on charts with two fingers and check when your battery left you or when it was discharging very fast.

You'll be able also to set alerts for your sensors.

You can use Sensor Charts as your personal tricorder.

*N.B.: Available sensors in the multi-tool depend on their actual presence on your device. Devices with a greater number of sensors can take full advantage of this app.
