Verdict
The clearest difference is rating: WordTower at 5.0 against Relingo's 4.0. WordTower also leads on update cadence (every 8 days vs every 3 weeks). Relingo's advantage is ratings volume (44 vs 1) and iOS requirement (13.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Relingo sells 2 in-app purchases, starting at $3.99 per month and WordTower sells 5 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
WordTower holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: Relingo has 44 ratings behind it against 1, so its average is the more settled of the two.
Relingo ships an update every 3 weeks, WordTower every 8 days. The most recent releases landed on November 3, 2026 and November 4, 2026 respectively.
