# NGO vs CoStream

The clearest difference is rating: CoStream at 5.0 against NGO's 2.1. CoStream also leads on in-app purchases (none vs 4) and update cadence (every 5 months vs every 36 months). NGO's advantage is ratings volume (7 vs 1) and iOS requirement (12.2 vs 16.6). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. NGO sells 4 one-off in-app purchases. CoStream asks for nothing beyond the download.

CoStream holds the better App Store score, 5.0 against 2.1. That said, the two scores are not equally well evidenced: NGO has 7 ratings behind it against 1, so its average is the more settled of the two.

NGO ships an update every 36 months, CoStream every 5 months. The most recent releases landed on September 17, 2026 and August 29, 2026 respectively.
