# Missing Numbers vs Number Sequences

The clearest difference is rating: Number Sequences at 4.7 against Missing Numbers's 3.5. Number Sequences also leads on update cadence (every 4 months vs every 38 months) and ratings volume (19 vs 2). Missing Numbers's advantage is review sentiment (100% vs 88%) and iOS requirement (12.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Missing Numbers costs $1.99 and Number Sequences $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Number Sequences holds the better App Store score, 4.7 against 3.5. That said, the two scores are not equally well evidenced: Number Sequences has 19 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 100% of Missing Numbers's written reviews are positive against 88% of Number Sequences's, so the app with the better star average is not the one people write more warmly about.

Missing Numbers ships an update every 38 months, Number Sequences every 4 months. The most recent releases landed on October 4, 2026 and October 8, 2026 respectively.
