Kazesio - Tide Charts & Tables
Fishing Tides, Wind & Waves
Free · In‑App Purchases
"See the sea at a glance."
Kazesio is a tide chart app built to answer one question fast: is it worth going?
■ One chart, the whole day
A 24-hour tide curve with a live "now" line, plus the dawn and dusk feeding windows shaded right into the chart background. You read the shape, not the numbers.
■ Wind shifts you can actually see
Wind, waves, rain and temperature share the same time axis as the tide — so "the wind picks up after noon" is obvious before you leave the house.
■ Drop a pin, done
No browsing port lists. Tap your spot on the map and the nearest tide station is matched automatically.
■ Tides a year ahead
Tide is computed from the almanac, so you can check next year's spring tides today. Weather, wind and waves run 15 days out.
■ Works with a weak signal
Spots and dates you have opened stay available offline. Outside Japan the tide itself is computed on your device, so it works with no connection at all.
■ Widgets and alerts
Countdown to the next high or low tide on your Home Screen and Lock Screen. Optional alerts 30 minutes before the tide turns, and an hour before first light.
■ Fishing log
Keep your catch, photos and a note together with that day's tide, wind and weather. Look back later and you start to see which tide works for you. Records stay on this device and are never sent anywhere.
■ Worldwide
3,538 tide stations across 115 countries are built in. Units follow your region — °F and knots and feet, or °C and m/s and meters.

Tide values are predictions. For navigation or anything safety-critical, use official tide tables from your national hydrographic authority.
