I don’t think the Free plan by itself would make the app that slow. I’d first check what happens in the Network tab of your browser and whether the delay is during image upload or page loading. Also, if the home page is running several searches or workflows when it opens, that can make the whole app feel much slower than expected.
can you post a screenshot of the workflow related to the camera?
Another point: I suggest checking which data is being loaded on the front end.
I had this same issue when I started working with Bubble.
One of my apps used several charts, and some of them were running searches across the entire database. I started using custom states with already-filtered data for the relevant pages, and that made the app significantly faster.
You may also want to check whether any repeating groups, charts, or dropdowns are performing heavy database searches directly on page load using the debug mode.
