# Combinations vs P=NP

The clearest difference is ads: Combinations at none against P=NP's shown. Combinations also leads on update cadence (every 2 months vs every 28 months) and ratings volume (39 vs 3). P=NP's advantage is rating (5.0 vs 4.6). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. Combinations sells 1 one-off in-app purchase and P=NP sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

P=NP holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Combinations has 39 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 98% of Combinations's written reviews are positive against 100% of P=NP's.

Combinations ships an update every 2 months, P=NP every 28 months. The most recent releases landed on September 19, 2026 and June 2, 2026 respectively.
