So many bugs

It’s been years since the UI has so many bugs and there are so many AI design tools that could fix this.

Response from developer

Thanks for your comment. We don't generally receive these comments for many weeks. But if there is something you want to get corrected, or to understand why it is that way, just email our developers at info@SailTimer.co for a prompt reply. For sailors, this is the only app in the world that accounts for tacking distances when calculating your optimal tacks and Tacking Time to Destination. It was also the first app to include polar plot learning, for better projections of your unique boat's speed on all points of sail. We have recently been focusing on adding features to the crowdsourced wind map animation (another first), and weather animations. We appreciate feedback, and will add it to our ongoing list for updates. There have been 3 updates so far in 2025. With version 6 the interface and features are becoming consistent across all platforms.
