# Whatzit vs The SpineApp

The clearest difference is in-app purchases: The SpineApp at none against Whatzit's 5. The SpineApp also leads on rating (5.0 vs 4.7) and review sentiment (100% vs 82%). Whatzit's advantage is update cadence (every 6 weeks vs every 8 months) and ratings volume (38 vs 1). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Whatzit sells 3 in-app purchases, starting at $29.99 per month. The SpineApp asks for nothing beyond the download.

The SpineApp holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Whatzit has 38 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 82% of Whatzit's written reviews are positive against 100% of The SpineApp's.

Whatzit ships an update every 6 weeks, The SpineApp every 8 months. The most recent releases landed on October 26, 2026 and October 16, 2026 respectively.
