Verdict
The clearest difference is review sentiment: Subtext at 100% against Unlock's 50%. Subtext also leads on rating (4.9 vs 1.0) and ratings volume (21 vs 1). Unlock's advantage is ads (none vs shown). On price, update cadence, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Subtext sells 13 in-app purchases, starting at $4.99 per 7 days and Unlock sells 3 in-app purchases, starting at $13.99 per month. Whichever you choose, the download price is not the number that matters.
Subtext holds the better App Store score, 4.9 against 1.0. That said, the two scores are not equally well evidenced: Subtext has 21 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 100% of Subtext's written reviews are positive against 50% of Unlock's.
Subtext ships an update fortnightly, Unlock every 10 days. The most recent releases landed on October 25, 2026 and October 23, 2026 respectively.
