# SpectrumView vs Vocal Range

The clearest difference is review sentiment: SpectrumView at 63% against Vocal Range's 20%. SpectrumView also leads on ads (none vs shown) and iOS requirement (9.0 vs 13.0). Vocal Range's advantage is rating (4.5 vs 3.1) and update cadence (every 3 weeks vs every 10 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. SpectrumView sells 7 one-off in-app purchases and Vocal Range sells 13 in-app purchases, starting at $4.49 per year. Whichever you choose, the download price is not the number that matters.

Vocal Range holds the better App Store score, 4.5 against 3.1. Both are backed by a comparable volume of ratings — 74 and 307 respectively. Written reviews complicate that: 63% of SpectrumView's written reviews are positive against 20% of Vocal Range's, so the app with the better star average is not the one people write more warmly about.

SpectrumView ships an update every 10 months, Vocal Range every 3 weeks. The most recent releases landed on September 21, 2026 and September 22, 2026 respectively.
