لغتنامهٔ دهخدا کتابی جامع شامل شرح و معنی واژگان زبان فارسی است. این لغتنامه، بزرگترین و مهمترین اثر علیاکبر دهخدا است، که بیش از ۴۰ سال از عمر او صرف آن شد. لغتنامهٔ دهخدا معنی، تفسیر، و شرح تاریخیِ شمار قابل توجهی از وامواژههای عربی که وارد فارسی شدهاند را نیز دارد. لغتنامهٔ دهخدا شامل بخش بزرگی از واژگان ادبی زبان فارسی، با معنای آنها و نیز کاربردشان در شعرها است. همچنین تمام کلمات اصیل فارسی در آن موجود است. با وجود این، این لغتنامه فاقد بخش اعظم واژگان علمی و فنی فارسی است که بیشتر در دهههای پس از تألیف لغتنامه به حوزهٔ زبان فارسی وارد شدند. نسخهٔ چاپی کنونی لغتنامه ۶۷٬۲۶۵ صفحهٔ سهستونیِ قطع رحلی با حروف ریز دارد. در چاپ دوم از دورهٔ جدید که به صورت ۱۵ جلد لغتنامه و یک جلد مقدمه به صورت رحلی چاپ شده، ۲۳٬۹۱۱ صفحه است Terms of Use (EULA): https://faizahmaddae.github.io/dehkhoda/terms-of-use.html Privacy Policy: https://faizahmaddae.github.io/dehkhoda/privacy-policy.html Apple Standard EULA: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
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.

On the App Store both sit at effectively the same score — 4.8 for 504 against 4.7 for لغتنامه دهخدا (کامل).

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.
