# Deflection Lite vs Beam HPC

The clearest difference is review sentiment: Beam HPC at 100% against Deflection Lite's 44%. Beam HPC also leads on monetization model (free vs paid) and iOS requirement (9.0 vs 15.0). Deflection Lite's advantage is rating (4.5 vs 4.0) and update cadence (every 3 months vs every 18 months). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Deflection Lite holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Deflection Lite has 46 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 44% of Deflection Lite'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 Lite ships an update every 3 months, Beam HPC every 18 months. The most recent releases landed on September 17, 2026 and September 2, 2026 respectively.
