# Algorithms vs Regex Tester

The clearest difference is rating: Regex Tester at 5.0 against Algorithms's 4.5. Regex Tester also leads on in-app purchases (none vs 3) and update cadence (every 5 days vs every 3 weeks). Algorithms's advantage is ratings volume (8 vs 1). On price, ads and device support there is nothing between them.

Both are free to download. Algorithms sells 3 one-off in-app purchases. Regex Tester asks for nothing beyond the download.

Regex Tester holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Algorithms has 8 ratings behind it against 1, so its average is the more settled of the two.

Algorithms ships an update every 3 weeks, Regex Tester every 5 days. The most recent releases landed on October 27, 2026 and October 24, 2026 respectively.
