# Light Spectrometer Wavelength vs SpectraMania

The clearest difference is price: Light Spectrometer Wavelength at Free against SpectraMania's $7.99. Light Spectrometer Wavelength also leads on update cadence (every 2 months vs every 6 months) and ratings volume (98 vs 4). SpectraMania's advantage is in-app purchases (none vs 7) and chart position (#129 vs unranked). On review sentiment, ads, device support and iOS requirement there is nothing between them.

Light Spectrometer Wavelength is free to download; SpectraMania costs $7.99 up front. Light Spectrometer Wavelength sells 4 in-app purchases, starting at $0.99 per month. SpectraMania asks for nothing beyond the download.

Light Spectrometer Wavelength holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: Light Spectrometer Wavelength has 98 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 71% of Light Spectrometer Wavelength's written reviews are positive against 75% of SpectraMania's, so the app with the better star average is not the one people write more warmly about.

Light Spectrometer Wavelength ships an update every 2 months, SpectraMania every 6 months. The most recent releases landed on November 11, 2026 and November 5, 2026 respectively.
