# ADSignify vs S3 Client

The clearest difference is review sentiment: ADSignify at 100% against S3 Client's 79%. ADSignify also leads on iOS requirement (15.0 vs 18.2). S3 Client's advantage is update cadence (every 9 days vs monthly) and rating (4.8 vs 4.6). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. ADSignify sells 4 in-app purchases, starting at $2.99 per month and S3 Client sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

S3 Client holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: S3 Client has 56 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 100% of ADSignify's written reviews are positive against 79% of S3 Client's, so the app with the better star average is not the one people write more warmly about.

ADSignify ships an update monthly, S3 Client every 9 days. The most recent releases landed on October 12, 2026 and October 14, 2026 respectively.
