Verdict
The clearest difference is in-app purchases: Subtext at none against Tester's 6. Subtext also leads on iOS requirement (14.4 vs 18.7). Tester's advantage is update cadence (every 2 days vs every 3 weeks) and rating (4.7 vs 4.5). On price, review sentiment, ads and monetization model there is nothing between them.

Both are free to download. Tester sells 6 in-app purchases, starting at $0.99 per month. Subtext asks for nothing beyond the download.
Tester holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Tester has 575 ratings behind it against 79, so its average is the more settled of the two. Written reviews point the same way: 90% of Tester's written reviews are positive against 83% of Subtext's.
Tester ships an update every 2 days, Subtext every 3 weeks. The most recent releases landed on October 3, 2026 and September 30, 2026 respectively.
