# ThinkSpace vs ロジックツリー

The clearest difference is ads: ThinkSpace at none against ロジックツリー's shown. ロジックツリー's advantage is update cadence (weekly vs monthly) and iOS requirement (10.0 vs 15.6). On price, review sentiment, in-app purchases and device support there is nothing between them.

Both are free to download. ThinkSpace sells 2 in-app purchases, starting at $2.99 per month and ロジックツリー sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ThinkSpace ships an update monthly, ロジックツリー weekly. The most recent releases landed on October 16, 2026 and October 8, 2026 respectively.
