We respect what Navionics does well. Here is exactly where we're different and where we're not.
They have the best charts in fishing. We have the best forecast. Different problems. If you fish from a boat with electronics integration, their charts are non-negotiable. If you fish from shore / kayak / small boat and the question is "is the bite on today?", a model that reads today’s conditions beats a static bathymetric chart every time.
Navionics is the gold standard for bathymetric charts in fishing — owned by Garmin, integrated with every major chartplotter. Fishare doesn't compete on chart detail. We compete on forecast quality. The two tools solve different sides of the same trip.
Navionics charts are non-negotiable for anyone running a boat with electronics — that's the moat, and we don't challenge it. Where the comparison gets interesting is for the rest of the angler population: shore, rock, kayak, small-boat and tinny anglers who don't have a chartplotter and don't need 1-foot bathymetric resolution because they're not navigating offshore structure. For that group, the question shifts from "what does the bottom look like?" to "is the bite on today?", and that's a different product.
A factual head-to-head across the features that matter for the fishing-decision use case.
| Feature | Navionics | Fishare |
|---|---|---|
| Bathymetric chart resolution | 1-foot HD in covered waters | Standard global tile maps (we don't compete on chart detail) |
| SonarChart (community contours) | Yes — millions of community uploads | No |
| Chartplotter integration | Yes — Garmin, Lowrance, Raymarine | No |
| Garmin marine-electronics ecosystem | Yes (since 2017 acquisition) | No |

| 7-day forecast | Basic weather | Full per-spot, per-species, per-hour |
| Tide stations | Yes | Thousands of harmonic tide stations worldwide |
| Surface currents | Yes | Yes — and where the shear lines set up (AU east + NZ) |
| SST / chlorophyll / eddy layers | No | Yes — SST and chlorophyll across AU east, NZ, US East + Gulf, UK and Japan; eddy structure AU east + NZ |
| Live AIS vessel layer | Some chartplotter models | In-app, free |
| Species-aware forecast | No | Yes — 207 profiled species, each with its own thermal sweet spot baked in |
| Aquatic-reserve closures | Limited / regional | Yes — NSW DPIRD polygons rendered |
| Catch logging | Basic | Yes — public/private toggle |
| Free tier | 14-day trial | Forever-free for browse + forecast |
| Hardware requirement | Software-only or chartplotter | PWA — any device |
Navionics's pricing structure against Fishare's. The forecast app is free; the ocean-intelligence layers (SST, HSI and friends) are the single paid tier.
Pricing verified May 2026 against Navionics web (US tier) and the AU App Store IAP. The AU regional subscription is markedly more expensive than the US Boating + Fishing tier — worth checking which region your App Store account is set to before subscribing. Auto-renew is the most common complaint in App Store reviews.
Live since July 2026. Users who signed up before the paid flip keep the layers free for life (founding members).
Limitations of Navionics that come up in our own use and in public reviews. We don't list these to attack the product — they're context for the routing below.
Navionics tells you the bottom is 18 m of rubble with a ledge at 22. It does not tell you that this Saturday afternoon's incoming spring tide on a south-easterly is the right window to fish that ledge for snapper. The decision layer is up to the angler.
The community-uploaded sonar moat is real in US lakes and salt — millions of contributions. Outside the US (AU, NZ, EU offshore), SonarChart Live coverage is patchier and the bathymetric advantage shrinks. Worth checking the coverage layer for your specific water before subscribing.
App Store reviews flag silent auto-renewal as the most common gripe. The subscription is set up to renew by default and cancellation requires App Store-level steps. Not a Navionics-specific problem (most subscription apps do this), but worth flagging.
The biggest unlock is chartplotter integration — and that means buying into the Garmin / Lowrance / Raymarine hardware ecosystem at $1,000+ to get the real value out of the Navionics charts. The mobile-only experience is intentionally a slice of what the hardware integration offers.
Use-case routing — diplomatic, not flippant. Each row names a specific angler profile and the better tool for that profile.
Bathymetric resolution and SonarChart Live are the entire game for that use case. No contest.
Hardware integration locks them in and the chart quality justifies it.
SonarChart Live US coverage is dense enough to be the deciding factor.
You're not reading bottom structure from a kayak — you're reading the conditions window. That's the forecast.
The bite-score forecast + tide + AIS combination answers more weekend questions than chart detail does.
The bathymetric advantage shrinks; the forecast model works globally.
Navionics was acquired by Garmin in 2017 — the strategic centre of gravity is the marine-electronics hardware ecosystem, not the consumer mobile app. That's why the mobile experience leans on chart browsing and feels light on forecast logic: forecast is not where Garmin makes money. We are pure software, no hardware tie-ins, and the forecast layer is the product. Different DNA, different roadmap.
No real migration step — Navionics charts and Fishare forecasts complement rather than substitute. Offshore boaters typically run Navionics on the plotter and Fishare on the phone for the bite-window decision. The two answer different questions on the same trip.
Comparison verified against Navionics web + iOS Boating + Fishing app, May 2026. Pricing taken from Navionics web pricing page and US App Store listing; verify in-app before subscribing. SonarChart Live coverage assessment based on the publicly visible coverage layer; your specific water may vary.
The forecast side is free forever — live map, bite score, 7-day forecast and spot pages, no account needed to browse. The ocean-intelligence layers (SST with isotherms and break detection, HSI habitat heatmap, chlorophyll, subsurface temperatures, altimetry) are the single paid tier: US$5.99/mo or US$49.99/yr across every covered region, with a free look over a window of your own local water.

A multi-input neural network scored per species, per hour — not a Solunar lookup. Inputs include wind, swell, tide stage, barometric pressure and trend, where the warm-cold water edges are, what the current is doing, moon phase, and a couple of dozen other features per hour. It is decision support built from live conditions, not a guarantee — we publish no accuracy figure, and some days the score is high and the water is dead.
Yes — the native iOS app is on the App Store (search is still indexing; the direct link is apps.apple.com/app/fishare/id6783726939), and it is free for everyone: there is no paid-tier gate on the app itself. A native Android app is on its way to Google Play. Until it lands, Fishare runs on Android as a Progressive Web App: open fishare.app in Chrome, then 'Add to Home Screen' — offline support and push notifications included.
July 2026. We re-verify pricing, feature parity and known limitations each time a major version of Navionics ships or pricing tiers change. The reviewed date at the top of the page is the source of truth.
They reflect the version of Navionics we checked at the last review date. Software changes; if you spot something that no longer matches the live product, let us know via the feedback link in the app and we'll update.
Fishare tracks your home spots and pings you when the next 3-hour peak window opens. Log catches and blanks to teach the model your local patterns. The forecast, saved spots and catch log stay free, forever.
