# Ring.io vs SmartCal Pro

The clearest difference is rating: SmartCal Pro at 5.0 against Ring.io's 4.4. Ring.io's advantage is in-app purchases (none vs 8) and ratings volume (7 vs 1). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. SmartCal Pro sells 8 in-app purchases, starting at $14.99 per month. Ring.io asks for nothing beyond the download.

SmartCal Pro holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Ring.io has 7 ratings behind it against 1, so its average is the more settled of the two.
