# Invisure vs Timezone Converter

The clearest difference is update cadence: Invisure at every 2 weeks against Timezone Converter's monthly. Timezone Converter's advantage is ratings volume (10 vs 2). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Invisure sells 1 in-app purchase, starting at $0.99 per month and Timezone Converter sells 2 in-app purchases, starting at $5.99 per month. 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 Invisure against 5.0 for Timezone Converter. That said, the two scores are not equally well evidenced: Timezone Converter has 10 ratings behind it against 2, so its average is the more settled of the two.

Invisure ships an update every 2 weeks, Timezone Converter monthly. The most recent releases landed on October 30, 2026 and November 5, 2026 respectively.
