Verdict
The clearest difference is in-app purchases: Concept at none against Signal's 1. Concept also leads on review sentiment (100% vs 68%) and rating (5.0 vs 4.7). Signal's advantage is ratings volume (1.1M vs 19) and chart position (#11 vs unranked). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. Signal sells 1 in-app purchase, starting at $1.99 per month. Concept asks for nothing beyond the download.
Concept holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Signal has 1.1M ratings behind it against 19, so its average is the more settled of the two. Written reviews point the same way: 68% of Signal's written reviews are positive against 100% of Concept's.
Signal ships an update weekly, Concept fortnightly. The most recent releases landed on November 10, 2026 and November 4, 2026 respectively.
