# Dolphin vs SATellar

The clearest difference is in-app purchases: Dolphin at none against SATellar's 9. Dolphin also leads on ratings volume (1.3K vs 2). SATellar's advantage is rating (5.0 vs 4.8). On price, update cadence, ads and monetization model there is nothing between them.

Both are free to download. SATellar sells 9 in-app purchases, starting at $4.99 per month. Dolphin asks for nothing beyond the download.

SATellar holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Dolphin has 1.3K ratings behind it against 2, so its average is the more settled of the two.

Dolphin ships an update every 2 weeks, SATellar fortnightly. The most recent releases landed on October 16, 2026 and October 6, 2026 respectively.
