About Observation Diary
Keep a plant observation diary with a daily photo and notes. Perfect for summer science projects and homework.
Choose from morning glory, sunflower, cherry tomato, luffa and more, or type in whatever you're growing. Then take one photo a day and jot down what you see.
Features
- A daily photo plus records: height, leaves, buds, flowers, and what you noticed
- Weather and temperature filled in automatically from your location, or pick them by hand
- A "Day N" view to follow growth over time
- Export an A4 diary as a PDF to print and hand in
- Track several plants at once
How to use
Pick a plant and set the planting date. Each day, tap "Today's record" to add a photo and a note. When you're done, export the PDF from the menu and print it.
Good to know
Observe with your own eyes and write it yourself. This app just helps you organize your own records neatly. Photos and records stay on your device and are never uploaded. Location is used only to auto-fill the weather, and it is optional.
