Welcome to the Fitbit Community @patricb! 
Great idea you know?
I've checked the list of the apps implemented, but at this time there's only the one named "Altimeter" by Marco Castiello. Have you tried it? It's pretty cool.
I've also checked if there's someone already on the move in creating this great app but, not so far. So, the best place to make your voice heard is the Feature Suggestion board on our community, which our product development teams consult regularly to ensure we're delivering on what our customers need and want. Please take a moment to visit and give us your feedback.
Our product team, community members, and developers look forward to reading and incorporating your suggestions into future versions of Fitbit trackers and apps.
I encourage you to take the challenge of creating this app. What do you think? 
I'll definitely use it! If you consider being the developer of this, check the article How do I develop new apps for the Fitbit App Gallery? for detailed information of the process.
Thank you so much for your feedback and for participating in our community!
