# GMT Time vs ExpoViewHelper

The clearest difference is ads: ExpoViewHelper at none against GMT Time's shown. ExpoViewHelper also leads on update cadence (every 6 days vs every 28 months) and monetization model (free vs ad-supported). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. GMT Time sells 1 one-off in-app purchase and ExpoViewHelper sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

GMT Time ships an update every 28 months, ExpoViewHelper every 6 days. The most recent releases landed on November 3, 2026 and October 30, 2026 respectively.
