# Polar Scope Align Pro vs POLARIE U

The clearest difference is price: POLARIE U at Free against Polar Scope Align Pro's $4.99. POLARIE U also leads on iOS requirement (11.0 vs 13.0). Polar Scope Align Pro's advantage is rating (4.9 vs 4.0) and ratings volume (310 vs 1). On review sentiment, update cadence, ads and in-app purchases there is nothing between them.

POLARIE U is free to download; Polar Scope Align Pro costs $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Polar Scope Align Pro holds the better App Store score, 4.9 against 4.0. That said, the two scores are not equally well evidenced: Polar Scope Align Pro has 310 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 97% of Polar Scope Align Pro's written reviews are positive against 100% of POLARIE U's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
