Solunar PRO, offline solunar activity times for fishing and hunting

Hi everyone,

I’ve been working on a Connect IQ app called Solunar PRO for fishing and hunting.

It calculates solunar activity times directly on the watch using the user’s GPS location. It works fully offline, with no phone and no internet required.

The app is based on solunar theory, popularized by John Alden Knight in the 1930s. It uses sun and moon positions, moonrise, moonset, moon overhead and moon underfoot times to estimate when fish and game may be more active. It is not a guarantee, just a planning tool to use together with weather, pressure, season and local knowledge.

Current screens:

  • Today: daily activity score, next major or minor window with countdown, sunrise and sunset

  • Windows: all major and minor periods for the day

  • Next 7 Days: quick planning view for upcoming trips

  • Moon: moon phase, illumination, moonrise and moonset

  • Glance: daily score and next activity window without opening the full app

I’m looking for feedback on the UI and usefulness of the data.

Would you add pressure trend or weather, or keep it focused only on solunar data?

Screenshots attached. Thanks for any honest feedback.
