Verdict
The clearest difference is review sentiment: Deep at 100% against Martin's 39%. Deep also leads on rating (4.5 vs 4.2). Martin's advantage is update cadence (weekly vs every 5 months) and ratings volume (251 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Martin sells 4 in-app purchases, starting at $35.00 per month and Deep sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Deep holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: Martin has 251 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 39% of Martin's written reviews are positive against 100% of Deep's.
Martin ships an update weekly, Deep every 5 months. The most recent releases landed on November 3, 2026 and October 30, 2026 respectively.
