# AB Quantum vs IPSC Quickscore

The clearest difference is review sentiment: IPSC Quickscore at 100% against AB Quantum's 45%. IPSC Quickscore also leads on rating (5.0 vs 4.7). AB Quantum's advantage is ratings volume (2.9K vs 2) and chart position (#107 vs unranked). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. AB Quantum sells 15 in-app purchases, starting at $2.99 per month and IPSC Quickscore sells 4 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

IPSC Quickscore holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: AB Quantum has 2.9K ratings behind it against 2, so its average is the more settled of the two.
