# Siggi vs One SMS

The clearest difference is in-app purchases: Siggi at none against One SMS's 10. One SMS's advantage is update cadence (every 3 days vs fortnightly). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. One SMS sells 10 one-off in-app purchases. Siggi asks for nothing beyond the download.

Siggi ships an update fortnightly, One SMS every 3 days. The most recent releases landed on September 26, 2026 and October 2, 2026 respectively.
