# Noji vs Thea

The clearest difference is ads: Thea at none against Noji's shown. Thea also leads on review sentiment (93% vs 64%) and rating (4.9 vs 4.6). Noji's advantage is update cadence (every 8 days vs monthly) and ratings volume (14K vs 2.5K). On price, in-app purchases, monetization model and iOS requirement there is nothing between them.

Both are free to download. Noji sells 17 in-app purchases, starting at $4.99 per month and Thea sells 2 in-app purchases, starting at $12.00 per month. Whichever you choose, the download price is not the number that matters.

Thea holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: Noji has 14K ratings behind it against 2.5K, so its average is the more settled of the two. Written reviews point the same way: 64% of Noji's written reviews are positive against 93% of Thea's.

Noji ships an update every 8 days, Thea monthly. Both last shipped on October 17, 2026.
