Hardwater — Ice Bytefrost

Hardwater is the offline companion for ice anglers. No accounts, no ads, no internet required — just the tools you actually use out on the hard water.

PLAN THE BITE
A solunar bite-forecast engine calculates the moon phase, major and minor feeding periods, dawn and dusk windows, and an overall daily bite score from 0–100. Add the current barometric trend (falling, steady or rising) and the forecast adjusts to match how fish really behave under the ice. Scroll forward and back day by day to pick your morning.

KEEP A CATCH JOURNAL
Log every fish in seconds: species, length, weight, depth, lure and notes. Track your personal best, species variety and catch-and-release totals. Your whole hardwater season, in your pocket.

MAP YOUR HOLES
Drop pins on an interactive lake map to remember exactly where you drilled. Save the depth of each hole and see how many fish each spot has produced, so you can head straight back to the honey hole next time.

STAY SAFE ON THE ICE
Enter your measured ice thickness and ice type (clear blue, white snow ice or slush) and instantly see whether it can hold a single angler, a group, a snowmobile or a vehicle. A built-in safety checklist reminds you of the essentials before every trip.
