Your Android app version is typically reviewed and accepted the day this is submitted, however the process with Apple can take a bit longer.  During the entirety of this process ShoutEm is unable to guarantee or provide a release date for your app, but we're happy help should any questions arise from the Apple/Google reviewers. You'll find more detailed information on this process below.

Apple:

Apple's app review process can take anywhere from 5-12 days. If timing of your app release is a concern, Apple offers an "expedited" app review, which you can submit through this form.

We recommend making sure your app is a complete as possible, including your "Design", "Publish Info" and "Content" elements.  Apple provides key information on their review process as part of there App Store Review Guidelines.

Google Play:

Google's app review process can take anywhere from 1-3 days, but is usually in the store within 24 hours of submission.
