MDict packages can include MDX, MDD, and accompanying resources. Keep dictionary files on your device or enable iCloud dictionary sync to use the same library on iPhone, iPad, and Mac.

ADD ON-DEVICE INTELLIGENCE With Pro, optionally enrich dictionary results using Apple's on-device Foundation Models and your own prompt rules. Intelligence Enrichment is off by default and requires iOS or iPadOS 26 or later, a supported device, and Apple Intelligence enabled with its model ready. Availability depends on Apple's supported languages and regions. MADE FOR IPHONE AND IPAD Search with native system controls, browse rich definitions, and choose a reading theme that suits you. On iPhone, the bottom search button keeps lookup within reach without hiding the current result. aDict Pro is a one-time, non-consumable in-app purchase, not a subscription.

Verdict
The clearest difference is rating: EReader at 4.8 against aDict's 3.0. EReader also leads on review sentiment (84% vs 50%) and monetization model (free vs freemium). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. aDict sells 1 one-off in-app purchase and EReader sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
EReader holds the better App Store score, 4.8 against 3.0. That said, the two scores are not equally well evidenced: EReader has 257 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 50% of aDict's written reviews are positive against 84% of EReader's.
aDict ships an update every 8 days, EReader every 11 days. The most recent releases landed on November 12, 2026 and November 11, 2026 respectively.
