The figures are in the order of magnitude that OP suggests, but only for a) games that b) are ad supported (which is how we know the numbers). More serious apps get to stay a few extra days from the looks of this blog post (among other similar promotional ones on the topic that are a few googles away): https://www.adjust.com/blog/unmasking-uninstalls/ https://www.adjust.com/blog/unmasking-uninstalls/ Seeing how e-commerce, travel, and health are the only three categories that get more than a week I'd spitball it's because users of these apps kept them for a one-time event. Either way, OP is correct in that as an app publisher, you're only one shot at getting that precious first impression, and odds are your new users will only keep the app around long enough to open it a few times; as few as once, in the case of games. Which sounds about right if my own anecdotal usage is anything to go by.
