# Sky Guide vs Integra Adhesives

The clearest difference is in-app purchases: Integra Adhesives at none against Sky Guide's 6. Integra Adhesives also leads on rating (5.0 vs 4.8) and iOS requirement (16.6 vs 18.0). Sky Guide's advantage is update cadence (every 2 weeks vs every 6 months) and ratings volume (378K vs 2). On price and ads there is nothing between them.

Both are free to download. Sky Guide sells 6 in-app purchases, starting at $4.99 per month. Integra Adhesives asks for nothing beyond the download.

Integra Adhesives holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Sky Guide has 378K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 86% of Sky Guide's written reviews are positive against 67% of Integra Adhesives's, so the app with the better star average is not the one people write more warmly about.

Sky Guide ships an update every 2 weeks, Integra Adhesives every 6 months. The most recent releases landed on October 22, 2026 and October 1, 2026 respectively.
