# DoCube vs Text Replace

The clearest difference is in-app purchases: Text Replace at none against DoCube's 1. Text Replace also leads on rating (5.0 vs 4.6) and iOS requirement (15.0 vs 17.0). DoCube's advantage is ratings volume (11 vs 2). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. DoCube sells 1 one-off in-app purchase. Text Replace asks for nothing beyond the download.

Text Replace holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: DoCube has 11 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.

DoCube ships an update every 3 weeks, Text Replace every 2 weeks. The most recent releases landed on September 19, 2026 and October 1, 2026 respectively.
