Find the bait before you leave the ramp.
TideScope fuses free satellite sea-temperature, chlorophyll, current and tide data into a single bait-aggregation score — then exports your best spots straight to Navionics and your Garmin chartplotter.
The problem
Fish don't hide. The data just isn't joined up.
Every serious offshore angler already juggles four or five apps before a trip. TideScope replaces the juggling with one score.
Finding fish is expensive
Commercial satellite layers run $30+/month. TideScope's entire data stack is free.
Data is scattered
SST, chlorophyll, currents, tides and solunar tables each live in a different app. Nothing talks to anything else.
Raw data isn't intelligence
A temperature map doesn't tell you where bait is congregating. Nobody scores it for you — until now.
Plotter integration is manual
Getting a hotspot coordinate from a website onto your Garmin is a fiddly, multi-step chore.
Workflow
From bait scores to your chartplotter in five taps.
Built around the way trailer-boat anglers actually plan a trip — on WiFi at home, offline at the ramp.
Fetch Intel
Pick a location and radius. TideScope pulls every layer for that patch of ocean.
Review Hotspots
See the aggregation score, plus SST, chlorophyll and current layers on a dark marine map.
Export GPX
Top hotspots — and any waypoints you've saved — export as a single GPX file.
Import to Navionics
Open the GPX in Navionics Boating — works the same on iPhone and Android.
Plotter Sync
Navionics pushes every waypoint to your Garmin MFD automatically. Head out and go.
Features
Everything on one dark, sea-legs-friendly map.
Aggregation scoring
Eddy edges, shelf breaks, thermal fronts, chlorophyll gradients and current convergence, weighted into one 0–100 score per grid cell.
Layer toggles
Switch instantly between Score, SST, SST anomaly, chlorophyll, currents, vorticity and depth — each with its own colour ramp.
Daily briefing panel
Moon phase, tide times, solunar major/minor windows and a wind & swell summary, all at a glance.
GPX export + Navionics
One tap exports top hotspots and saved waypoints, ready for Navionics Plotter Sync to your Garmin.
Offline mode
Fetch intel on WiFi at the ramp, then lose signal all day — the map, scores and tides stay with you.
Any location, sea-only
Tap anywhere or use GPS. A 50km radius auto-draws, and land cells are masked out of every score.

One map, every ocean signal.

Data, not guesswork
Every layer sourced from free, public ocean data.
No paywalled satellite feeds. The entire stack runs at $0/month.
Built in Jurien Bay. Ready to test with you.
TideScope is currently a small private beta running on iPhone and Android. If you fish offshore and want early access, get in touch.
