About

Blip Daily

Read full description

Dear User, With the Blip Daily app, you can set reminders for every two, three, four, or five days. Sometimes, doctors advise taking prescriptions every two to three days to prevent forgetting doses. The Blip Daily app will help you remember to take your medicine in such cases. If you want reminders on weekdays, you can select multiple options (e.g., every Sunday, Monday). However, for reminders based on specific days, you can only choose one option. After selecting your preferred options, click the "Set Blips" button in the top right corner. You will then be prompted to choose three times for reminders: morning, afternoon, and night. You can skip any of these times. For example, if you only want a morning reminder, you can skip the other two.
