# Polar Scope Align Pro vs EclipseGo

The clearest difference is price: EclipseGo at Free against Polar Scope Align Pro's $3.99. EclipseGo also leads on update cadence (every 3 weeks vs every 2 months). Polar Scope Align Pro's advantage is ratings volume (305 vs 2) and chart position (#105 vs unranked). On rating, ads, in-app purchases and monetization model there is nothing between them.

EclipseGo is free to download; Polar Scope Align Pro costs $3.99 up front. Polar Scope Align Pro sells 3 one-off in-app purchases and EclipseGo sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for Polar Scope Align Pro against 5.0 for EclipseGo. That said, the two scores are not equally well evidenced: Polar Scope Align Pro has 305 ratings behind it against 2, so its average is the more settled of the two.

Polar Scope Align Pro ships an update every 2 months, EclipseGo every 3 weeks. The most recent releases landed on September 30, 2026 and September 19, 2026 respectively.
