Users who are on an iPad need landscape mode for the Dex Mobile app.

Be able to quickly add reminders for a contact without going to reminders tab.

When clicking the box, it makes 2 "We met!" entries on the contact's timeline.

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

My main usecase for the mobile app is to open a page about a contact (either viewing or editing). Right now, we need to go to contacts first and then search (2 clicks). It would be nice to have the search bar in the main page of the mobile app reducing the number of clicks

Be able to see all contacts with phone, or linkedin, etc.

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