# Lumy vs Lightphase

The clearest difference is in-app purchases: Lightphase at none against Lumy's 3. Lightphase also leads on review sentiment (100% vs 79%) and rating (5.0 vs 4.8). Lumy's advantage is ratings volume (2.4K vs 2) and update cadence (every 3 days vs every 2 weeks). On ads and iOS requirement there is nothing between them.

Lumy costs $7.99 and Lightphase $4.99 up front. Lumy sells 3 one-off in-app purchases. Lightphase asks for nothing beyond the download.

Lightphase holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Lumy has 2.4K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 79% of Lumy's written reviews are positive against 100% of Lightphase's.

Lumy ships an update every 3 days, Lightphase every 2 weeks. The most recent releases landed on October 23, 2026 and October 12, 2026 respectively.
