# Frequency Generator vs Voice Studio

The clearest difference is ads: Voice Studio at none against Frequency Generator's shown. Voice Studio also leads on update cadence (every 11 days vs every 2 months). Frequency Generator's advantage is ratings volume (16 vs 1). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Frequency Generator sells 4 in-app purchases, starting at $4.99 per 7 days and Voice Studio sells 2 in-app purchases, starting at $9.99 per year. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Frequency Generator against 5.0 for Voice Studio. That said, the two scores are not equally well evidenced: Frequency Generator has 16 ratings behind it against 1, so its average is the more settled of the two.

Frequency Generator ships an update every 2 months, Voice Studio every 11 days. The most recent releases landed on July 8, 2026 and September 8, 2026 respectively.
