# AB Quantum vs Strelok Pro

The clearest difference is rating: AB Quantum at 4.7 against Strelok Pro's 3.8. AB Quantum also leads on ratings volume (2.9K vs 28) and review sentiment (45% vs 20%). Strelok Pro's advantage is update cadence (every 4 days vs fortnightly). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. AB Quantum sells 15 in-app purchases, starting at $2.99 per month and Strelok Pro sells 5 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

AB Quantum holds the better App Store score, 4.7 against 3.8. That said, the two scores are not equally well evidenced: AB Quantum has 2.9K ratings behind it against 28, so its average is the more settled of the two. Written reviews point the same way: 45% of AB Quantum's written reviews are positive against 20% of Strelok Pro's.

AB Quantum ships an update fortnightly, Strelok Pro every 4 days. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
