# LightSpectrum Pro vs Clear Spaces

The clearest difference is rating: LightSpectrum Pro at 4.1 against Clear Spaces's 3.3. LightSpectrum Pro also leads on price ($1.99 vs $2.99). Clear Spaces's advantage is update cadence (every 4 days vs every 3 months) and ratings volume (589 vs 39). On ads, in-app purchases, monetization model and device support there is nothing between them.

LightSpectrum Pro costs $1.99 and Clear Spaces $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.

LightSpectrum Pro holds the better App Store score, 4.1 against 3.3. That said, the two scores are not equally well evidenced: Clear Spaces has 589 ratings behind it against 39, so its average is the more settled of the two. Written reviews complicate that: 28% of LightSpectrum Pro's written reviews are positive against 38% of Clear Spaces's, so the app with the better star average is not the one people write more warmly about.

LightSpectrum Pro ships an update every 3 months, Clear Spaces every 4 days. The most recent releases landed on September 22, 2026 and September 23, 2026 respectively.
