Verdict
The clearest difference is review sentiment: REVERSI ZERO at 87% against Othello for all's 36%. REVERSI ZERO also leads on update cadence (monthly vs every 3 months) and ratings volume (75 vs 18). Othello for all's advantage is rating (4.7 vs 4.4). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Othello for all sells 2 in-app purchases, starting at $0.99 per month and REVERSI ZERO sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Othello for all holds the better App Store score, 4.7 against 4.4. Both are backed by a comparable volume of ratings — 18 and 75 respectively. Written reviews complicate that: 36% of Othello for all's written reviews are positive against 87% of REVERSI ZERO's, so the app with the better star average is not the one people write more warmly about.
Othello for all ships an update every 3 months, REVERSI ZERO monthly. The most recent releases landed on September 24, 2026 and September 22, 2026 respectively.
