Decision Support Tool for Shore & Coastal Angling
ShoreMark is engineered for anglers who fish rock shelves, breakwaters, beaches, and harbors. It unifies atmospheric pressure, wind, temperature, daylight, and solunar times into an intuitive hourly fishing score—while keeping your catch log private, with coordinates encrypted on your device.
Scores are estimates, not guarantees; always trust real-time safety observations on the water.
On-Device AES-256-GCM Encryption · Camera Length Measurement · iOS 17.0+
Real In-App Preview · ShoreMark Pro
The Go-Time score combines solunar times, daylight, wind, pressure, and temperature. Scroll through the hourly ribbon or jump straight to the day's peak window with a single tap.
7-day extended forecasts and tactical lure directives unlocked with ShoreMark Pro.
Live Navigation · Spot Discovery Map
Select your target species and target time; nearby piers, rocky points, and coastal marks appear with color-coded potential pins. Adjust your radius from 10 km to 100 km and bookmark up to 10 favorite secret marks.
Pin scores update as conditions change.
Telemetry · Weather & Solunar Clock
Inspect real-time atmospheric metrics including air temperature, wind knots, barometric pressure, and precipitation. The integrated 24-hour solunar timeline plots moon overhead/underfoot transit windows (Major & Minor) with high visual clarity.
Current & next-day forecasts free forever. Powered by Apple WeatherKit.
Organization · Catch Log
Record species, size, weight, bait and water type for each catch, and keep your own history of what worked.
Engineered For The Outdoors
The score draws on solunar times, daylight, wind, pressure, and temperature, and changes smoothly from hour to hour. It is an estimate, not a guarantee.
Your fishing spots stay in your private log; there is no social feed. All catch coordinates are encrypted on-device via AES-256-GCM before transmission. EXIF GPS metadata is completely stripped from photos prior to uploading.
Measure your catch with your phone camera and a reference object, or enter the length by hand. Fishing rules vary by country, so check your local regulations.
High-contrast screens built for bright daylight. Designed with dark slate/gunmetal surfaces and high-visibility single-accent coral highlights (WCAG AAA compliant), legible in direct sunlight with wet hands. Minimum 44x44 pt touch targets throughout.
Encrypted Coordinates
Coordinates you pin or record with GPS are encrypted on your phone using 256-bit AES-GCM. Our database only stores ciphertext; the key is bound to your account and kept server-side in wrapped escrow.
When you snap a trophy photo, camera-embedded EXIF metadata (exact coordinates, altitude, heading) is stripped on your device before the image leaves your hand.
Weather lookups never reveal your exact position; requests query a coarse 5 km × 5 km regional grid center.
