# Deflection vs Beam HPC

The clearest difference is price: Beam HPC at Free against Deflection's $4.99. Beam HPC also leads on review sentiment (100% vs 74%) and iOS requirement (9.0 vs 15.0). Deflection's advantage is rating (4.6 vs 4.0) and update cadence (every 6 weeks vs every 18 months). On ads, in-app purchases and device support there is nothing between them.

Beam HPC is free to download; Deflection costs $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Deflection holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Deflection has 115 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 74% of Deflection's written reviews are positive against 100% of Beam HPC's, so the app with the better star average is not the one people write more warmly about.

Deflection ships an update every 6 weeks, Beam HPC every 18 months. The most recent releases landed on October 22, 2026 and October 19, 2026 respectively.
