Do you ever save a contact just for the purpose of retaining its number, but don't want it to appear in your daily feed? If so, you're not alone.

That's where ContactX comes in - it lets you save these non-important contacts without adding them to your daily feed. Also, you can

call
notified about who's calling
sms
send WhatsApp and Telegram texts
all of these, without the contact being added to your stock phonebook.
