# Days between Dates vs The Date Calculator PRO

The clearest difference is rating: The Date Calculator PRO at 4.7 against Days between Dates's 4.2. The Date Calculator PRO also leads on ratings volume (2.6K vs 19) and update cadence (every 4 months vs every 17 months). Days between Dates's advantage is ads (none vs shown) and review sentiment (79% vs 66%). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Days between Dates sells 1 one-off in-app purchase and The Date Calculator PRO sells 7 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

The Date Calculator PRO holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: The Date Calculator PRO has 2.6K ratings behind it against 19, so its average is the more settled of the two. Written reviews complicate that: 79% of Days between Dates's written reviews are positive against 66% of The Date Calculator PRO's, so the app with the better star average is not the one people write more warmly about.

Days between Dates ships an update every 17 months, The Date Calculator PRO every 4 months. The most recent releases landed on October 3, 2026 and October 15, 2026 respectively.
