I have a client that wants to create an app that lets him share is picks. Is this something that the store allows? There is no betting money being collected on the app.
Sports betting App
You say it would be a Sports betting app but there is no money betting collected. Where does betting occur ?
Check you comply with Guideline 5.3.4:
5.3.4 Apps that offer real money gaming (e.g. sports betting, poker, casino games, horse racing) or lotteries must have necessary licensing and permissions in the locations where the app is used, must be geo-restricted to those locations, and must be free on the App Store. Illegal gambling aids, including card counters, are not permitted on the App Store. Lottery apps must have consideration, chance, and a prize.
