# HD Level ⊜ vs Bubble Level + Compass

The clearest difference is in-app purchases: Bubble Level + Compass at none against HD Level ⊜'s 1. Bubble Level + Compass also leads on rating (5.0 vs 4.7) and update cadence (every 4 months vs every 8 months). HD Level ⊜'s advantage is ads (none vs shown) and ratings volume (283 vs 34). On price, review sentiment, monetization model and device support there is nothing between them.

Both are free to download. HD Level ⊜ sells 1 one-off in-app purchase. Bubble Level + Compass asks for nothing beyond the download.

Bubble Level + Compass holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: HD Level ⊜ has 283 ratings behind it against 34, so its average is the more settled of the two. Written reviews complicate that: 94% of HD Level ⊜'s written reviews are positive against 90% of Bubble Level + Compass's, so the app with the better star average is not the one people write more warmly about.

HD Level ⊜ ships an update every 8 months, Bubble Level + Compass every 4 months. The most recent releases landed on October 4, 2026 and October 5, 2026 respectively.
