Are you looking at a download size or installed size? I have Uber on my iPhone and it's 150 MB for the "App Size" and another 14 MB for "Documents and Data".
Lyft app size 43.33 MB, user data 1.09 MB. Android 8.0.0. I wonder why such a spread in size?
Probably AOT compilation and extraction of some resources from the APK. I don't have either installed, but my point was that 200 MB seems like a gross exaggeration. At worst, you could use ride.lyft.com in your web browser.
On my Android phone, the system says Uber is 190MB plus 3MB of data.
