# Stockbook vs SSI iBoard Pro

The clearest difference is rating: SSI iBoard Pro at 4.3 against Stockbook's 3.5. SSI iBoard Pro also leads on ratings volume (109 vs 6) and update cadence (every 8 days vs every 3 weeks). Stockbook's advantage is review sentiment (50% vs 41%) and iOS requirement (12.0 vs 15.5). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

SSI iBoard Pro holds the better App Store score, 4.3 against 3.5. That said, the two scores are not equally well evidenced: SSI iBoard Pro has 109 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 50% of Stockbook's written reviews are positive against 41% of SSI iBoard Pro's, so the app with the better star average is not the one people write more warmly about.

Stockbook ships an update every 3 weeks, SSI iBoard Pro every 8 days. The most recent releases landed on September 19, 2026 and October 30, 2026 respectively.
