# ExchangeU vs Biddie

The clearest difference is in-app purchases: ExchangeU at none against Biddie's 7. ExchangeU also leads on rating (5.0 vs 4.8) and iOS requirement (15.1 vs 26.0). Biddie's advantage is ratings volume (21 vs 3). On price, ads and device support there is nothing between them.

Both are free to download. Biddie sells 7 in-app purchases, starting at $4.99 per year. ExchangeU asks for nothing beyond the download.

ExchangeU holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Biddie has 21 ratings behind it against 3, so its average is the more settled of the two.
