I am looking for a phone app that will track speed, location, heart rate, and also allow my to see my di2 gear information. Do Any apps pair with di2? Bonus if I can get the buttons on my road shifters to answer calls or play music on my phone. I don't ride with a computer but my heart rate and power goes straight to ride with GPS so looking for an app with just one more connection.

not Strava, they don't pair with anything complex anymore ...
To get connection to your di2 you may have to get a Garmin or Wahoo computer.

Some smartphones (Samsung and others) have ant+ radio receivers (can be used with ant+ sensors, like hrm)
Di2 gear information is send via ant radio channels using "private ant" protocol, so data is encoded
To decode this data decryption key is needed, this key is shared by Shimano to Wahoo, Garmin, Bryton, ...
keys are not given to app developers, and hardware developers most likely not allowed to share them
