I would like to write my entries on a computer, is it possible?

Daylio does not provide native web application. First, we want to improve our mobile applications. Maybe in the future?

If you much rather use Daylio on your Windows computer and you are not afraid of an extra work you can use Bluestacks - which emulates complete Android OS. You can get it here > https://www.bluestacks.com/

However, if you are running two or more Daylio apps on one Google Account you need to make sure to backup and restore everytime you want to switch app. Therefore we always recommend using only one app and if you choose PC, it will be much easier to use only PC.
