+Science Journal is the free digital science notebook brought to you by Google.
+\n
+\nWhether you\'re a science educator or a hobbyist doing science at home, you can keep your notes, photos, and observations all in one convenient place. Use the sensors in your phone to measure and graph phenomena such as light, sound, and motion, or connect to external sensors via bluetooth to conduct experiments on the world around you.
+\n
+\nWith the Science Journal app, you can:
+\n\u2022 Measure light, sound, acceleration, air pressure, and more using your phone\'s built-in sensors.
+\n\u2022 Take notes and photos to document your science experiments. More note types coming soon!
+\n\u2022 Connect to external sensors using select Bluetooth-enabled Arduino and Vernier devices.
+\n\u2022 Access your experiments across your devices using Google Drive.
+\n\u2022 Export recorded sensor data as CSV files.
+\n\u2022 Create automated triggers for recording data and taking notes.
+\n\u2022 Use sonification to hear the movement of your graphs.
+\n
+\nScience Journal is available for free on Android, iPhone, iPad, and compatible Chromebook devices.
+\n
+\nEducational activities by our partners: https://makingscience.withgoogle.com/science-journal/activities
+\nFor support: https://productforums.google.com/forum/#!forum/sciencejournal
+\nOpen-source code available: https://github.com/google/science-journal
+\n\n
+Permissions notice:
+\n\u2022 Location: needed to scan for bluetooth sensor devices.
+\n\u2022 Camera: needed to take pictures to document experiments.
+\n\u2022 Microphone: needed for sound intensity sensor.
+\n\u2022 Storage: needed to access photos to insert into experiments.
