Show a screen/section that shows newly created phone contacts that haven't yet been added to Dex

I would suggest using flutter, will make it faster and cheaper to develop. Look at google trends to see the flutter growth

Users should be able to quickly update the 'Last interaction' date to reset the keep-in-touch reminder.

Be able to leave voices notes for a user.

Be able to share into Dex (e.x. share a Instagram profile into Dex)

I use iMessage and other text messaging apps a lot. It would be nice to be able to post updates from the texts to Dex in a much more seamless manner than having to open the Dex app up. I've seen people be able to "share" to an app or in other cases have an app connected to the messager (included screenshot).

On iOS please add shortcuts or a haptic touch menu for the app icon. There are too many steps involved to take a quick note about someone. E.g. when I just learned something important about someone during a conversation, I want to get to the entry by just one tap.

I'd like to be able to sort/add my contacts in groups, the same way as the keep in touch page.

On creating an event all the additional details are below the keyboard which makes for a confusing experience. It would be nice the date / persons to be at the top so after naming the event you can click to the next part of the workflow without needing to click "done"
