# 504 vs لغتنامه دهخدا (کامل)

The clearest difference is ratings volume: 504 at 4.6K against لغتنامه دهخدا (کامل)'s 52. 504 also leads on update cadence (fortnightly vs monthly). لغتنامه دهخدا (کامل)'s advantage is review sentiment (85% vs 73%) and iOS requirement (15.0 vs 18.0). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. 504 sells 12 in-app purchases, starting at $4.99 per 7 days and لغتنامه دهخدا (کامل) sells 2 in-app purchases, starting at $3.99 per 6 months. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for 504 against 4.7 for لغتنامه دهخدا (کامل). That said, the two scores are not equally well evidenced: 504 has 4.6K ratings behind it against 52, so its average is the more settled of the two. Written reviews are what separate them: 73% of 504's written reviews are positive against 85% of لغتنامه دهخدا (کامل)'s.

504 ships an update fortnightly, لغتنامه دهخدا (کامل) monthly. The most recent releases landed on September 26, 2026 and September 10, 2026 respectively.
