# Inner Circle vs Stack Tower

The clearest difference is rating: Stack Tower at 5.0 against Inner Circle's 3.6. Inner Circle's advantage is ads (none vs shown) and update cadence (every 2 months vs every 5 months). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. Inner Circle sells 2 one-off in-app purchases and Stack Tower sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Stack Tower holds the better App Store score, 5.0 against 3.6. That said, the two scores are not equally well evidenced: Inner Circle has 9 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Inner Circle ships an update every 2 months, Stack Tower every 5 months. The most recent releases landed on October 9, 2026 and October 6, 2026 respectively.
