"In the App Store, app ratings are taken into account for search results, and top chart rankings. Apps that have a lot of ratings, and are rated positively are less prone to fluctuate in the app ranking charts and therefore more likely to hold their positions longer."

"In search results, positive app ratings help an app appear higher in the results."

"On a more personal note, when I see an app with a 3.5 star rating or below I’m hesitant to even install it, fearing a poor experience. I’d assume I’m not alone there."

"Don’t interrupt someone’s experience."

"Don’t ask for an app rating after your app has crashed. That’s just stupid."

"Do delay asking for a rating until there’s a likely moment of constructive feedback (as you’ll read later), or a positive rating."

"What we decided upon is that we would wait to present the ask until the user has opened the app at least 10 times, over the course of 3 distinct days. This means that we’re self-selecting into a smaller group — sure — but a group that’s more likely to give a positive rating."

"Ask a question. Don’t beg."

"The only way to becoming a 5-star app is to first have an excellent user experience. Once that first requirement is met, implementing a user-friendly feedback system such as the one above should help. Always put yourself in the shoes of your users."
