About 5-6 years ago, Timelinize actually used only the Google Photos API. It didn't even support imports from Takeout yet. The problem is the API strips photos of crucial metadata including location, and gives you nerfed versions of your data. Plus the rate limits were so unbearable, I eventually ripped this out.
But yeah, an app that runs on your phone would be a nice QoL improvement.
