# Assyst vs Oki

The clearest difference is price: Oki at Free against Assyst's $0.99. Oki also leads on review sentiment (64% vs 24%) and ads (none vs shown). Assyst's advantage is chart position (#51 vs unranked) and iOS requirement (15.0 vs 17.0). On rating, in-app purchases, monetization model and device support there is nothing between them.

Oki is free to download; Assyst costs $0.99 up front. Assyst sells 8 one-off in-app purchases and Oki sells 11 in-app purchases, starting at $1.00 per month. Whichever you choose, the download price is not the number that matters.

Assyst holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Oki has 391 ratings behind it against 18, so its average is the more settled of the two. Written reviews complicate that: 24% of Assyst's written reviews are positive against 64% of Oki's, so the app with the better star average is not the one people write more warmly about.

Assyst ships an update fortnightly, Oki every 4 days. The most recent releases landed on October 18, 2026 and October 21, 2026 respectively.
