    One thing I noticed after clearing space in some apps or after using/updating the app themselves is that over time, these apps take more disk space than they should and the only way to fix that is either deleting and reinstalling the app, or doing a reinstall from the entire system.

    For example, let's say the app BITTORRENT SYNC. While I installed for the first time, it was taking 20 MB. Then I changed a few settings, added some large files to it, I mean, 20 times for files with 1-5 GB each. And moved these videos for my other iPad, with the SYNC app in it. Then I deleted all internal files from it, and the app should have continued to waste 20 MB again, because that was its condition without multiple uses.

    However, now it's wasting 190 MB. I then deleted, and reinstalled with the modified settings. Wasting 20 MB again. That doesn't make any sense, no app takes 190 MB without justification. And what is even worse is that this app have not received any updates.

    There's another app in the same condition: IMDB. Over time, it received I think two updates, and grew from the same 20 to 190 MB (numbers are not precise, but that was how much iPad space it was taking). And in this case I didn't change any settings. Simply reinstalled the app, and again returned to waste 20 MB.

    That tells me once an app is used, it will grow like a tumor in the iPad, and the only way to fix this is reinstalling.

    Don't believe me? Here's another proof: do the math and tell me how I am wasting 17.6 GB here:

    What should I do to fix the problem above? Erase (format)?

    Unlike Android, iOS does not allow users to clear cache memory of the apps and rather leaves that decision to the app developer's discretion. Over time, cached data used by apps get accumulated, hence increasing the app's memory. Now, few apps do include an option to clear cache in their respective settings, but most apps don't.

    Of course, this does not mean that an app's cache never gets erased. When an app does not include an option to manually clear cache, an automatic command preempts clearing of cache once a developer-specified maximum space is reached. Unfortunately, I have observed that developers are quite generous at setting this limit, and can go beyond 1 GB.

    For now the only solution for apps that do not support clearing cache manually, as rightly observed by you, is to reinstall that app.
