About
Condor eDiary is the diary app from Condor Instruments. Formerly named Sleep Diary, it now supports diaries of different kinds — not only the sleep diary.
WHAT YOU DO IN THE APP
• Fill in your sleep diary every day, at the time agreed with your research team.
• Fill in additional diaries created specifically for your study, each with its own questions and its own filling window.
• Keep track of what has been filled in and what is still pending, day by day.
• Get reminders so you never miss an entry.
YOUR DEVICE, IN THE SAME PLACE
If you wear a Condor ActLumus actigraph, the app connects to it over Bluetooth and sends your research team the activity and light-exposure measurements the device recorded. You don't need to do anything beyond keeping the app installed and Bluetooth on.
WHO IT IS FOR
Condor eDiary is used in studies and follow-ups conducted by researchers and health professionals. Access is granted by the institution running your study — there are no in-app purchases.
THE NAME CHANGED, THE APP DID NOT
This is the same app you already used as Sleep Diary. Your data, your diaries and your access stay exactly as they were.

• Clearing the Condor watch memory is more reliable. • A new step-by-step guide to exempt the app from battery optimization on Android, so collection keeps running in the background. • In the sleep diary, it is easier to record last night's bedtime: the hour wheel crosses midnight and the date shows "Yesterday". • More reliable diary reminders. • Improved reconnection to the watch and a better device list. • Stability fixes.
