We forget things easily today and also with the information overload today we can’t just keep everything in our minds. So one of the most used app for me since around 8 years now is the Reminder App from Apple. It’s like on of my personal butlers which just helps me to remind me about appointments or things I wanted to do at a specific time. It helps me also to keep my mind more clear because not trying to keep everything in my mind. Give it a try if you haven’t used a reminder yet. It will help you a lot.
