# BellSense vs Stack

The clearest difference is in-app purchases: Stack at none against BellSense's 2. BellSense's advantage is update cadence (every 3 days vs every 10 days) and ratings volume (17 vs 2). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. BellSense sells 2 in-app purchases, starting at $29.99 per month. Stack asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for BellSense against 5.0 for Stack. That said, the two scores are not equally well evidenced: BellSense has 17 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

BellSense ships an update every 3 days, Stack every 10 days. The most recent releases landed on October 31, 2026 and October 24, 2026 respectively.
