How to estimate the number of downloads of an app in ONE day?

Apps on Play Store or iTunes. They only provide total numbers with wide band like from 500,000 to 1,000,000. That's a big difference. Anyone knows? Thanks a lot!

Need to find out from the download site (Play Store, iTunes) or from the distributor of the app. They get details stats.
