App Review times have varied a great deal over time. From the first days of the App Store until now. The longest App Review we ever saw was nine months and it was only approved after meeting with a reviewer in person. The shortest app review time was approximately 2 hours.
Android App Review Times:
Initially only Apple had a review period and Android did not. Android apps were for the most part published within six hours. However, that has changed and now Apps are reviewed on the Android platform just like on iOS. Having said that the majority of Apps on Android still get approved and go live within six hours. However, if your app is one of the “unlucky” few that is going to get extra review it seems to take a few days to a week to get a response on a review. What we typically tell customers is that it takes 1-2 business days to be reviewed but as you can see above it does vary depending on if you are “unlucky” or not.
Apple App Review Times:
Right now for most apps they will be reviewed and responded typically in 1-3 business days. Typically you will receive an approval in 1-2 business days if the app is approved. If the app is to be rejected usually this takes 2-3 business days which is where our 1-3 business days review period comes from combining these above two numbers. Though it is true that the majority of apps are reviewed and approved within the first business day. But when giving estimates we always like to include the 1-3 business days estimate.
