    ExMoment is a tool for the mind, designed to immortalize your thoughts and memories. To achieve that, you create your own avatar and start training it. Similar to the “Tamagotchi” device from years past, you have to train and share your memories with your avatar every day in order to keep it posted and notified about your daily life. You can also find more interesting facts about your avatar.

    Stick to the everyday tasks of your avatar, train it successfully, and preserve your personality long after the final bell rings. In the device itself, your friends and family can speak with you even when you're not online. Your avatar will be there for them! As we say, "Grab the future, don’t miss the moment!"

    - WordPress core
