What's New in SM Offset
1.3.0
September 28, 2026
Patterns has been removed from Offset. Also gone: the "Rolling Ninety" card on the Round screen. It was a placeholder, not a calculator. Every calculator is free and uncapped. A small banner ad at the bottom of the screen is what pays for it. Ads are non-personalised: no tracking prompt, no advertising identifier, and nothing you enter ever reaches an ad network.
