# Poly Thai Reader vs Thai90Days

Poly Thai Reader and Thai90Days both sit at 5.0 stars, but that hides the real split: 100% of Thai90Days's written reviews are positive against 80% of Poly Thai Reader's. Thai90Days also leads on update cadence (fortnightly vs monthly). Poly Thai Reader's advantage is ratings volume (9 vs 1) and iOS requirement (17.4 vs 26.5). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Poly Thai Reader sells 3 in-app purchases, starting at $9.99 per month and Thai90Days sells 2 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Poly Thai Reader against 5.0 for Thai90Days. That said, the two scores are not equally well evidenced: Poly Thai Reader has 9 ratings behind it against 1, so its average is the more settled of the two. Written reviews are what separate them: 80% of Poly Thai Reader's written reviews are positive against 100% of Thai90Days's.

Poly Thai Reader ships an update monthly, Thai90Days fortnightly. The most recent releases landed on October 21, 2026 and October 25, 2026 respectively.
