## Description

SailTimer is a marine weather and chartplotter app built for all boaters. It combines crowdsourced wind and sea-state data with offline maps to provide actionable conditions along your route, including wind direction, speed, and polar-tack analysis. For sailboats, it offers optimal tacks via tacking distance and polar plots and can auto-update from the SailTimer Wind Instrument. The app supports all boat types, route planning, waypoint management, and Navionics chart imports.

Key features include: animation of wind maps, Follow-Me GPS tracking, offline charts, waypoint creation/import, and the ability to save or share trip screenshots. It also provides wind gauge readings (TWD/TWA) and optional audio feedback. Subscriptions may be required for wind map animation and WNI weather services, and performance may vary on older devices with limited RAM.

## Review summary

SailTimer™ offers useful sailing navigation features and works well on some devices, appealing to new sailing learners. However, multiple users report frequent app crashes, a buggy user interface, and issues with the registration process. The requirement to pay to unlock Navionics charts causes frustration, especially since some find the charts insufficient or the integration poor. Overall, the app has good ideas but needs significant improvements in stability and usability.
