Honest comparison · Pro-grade offshore SST + altimetry imagery

RipCharts vs Fishare.

We respect what RipCharts does well. Here is exactly where we're different and where we're not.

What RipCharts owns
  • The deepest raw SST stack in fishing — raw orbit scans, composites, cloud-free, sub-surface SST at 0/-25/-50/-100 m
  • 4–12 SST updates a day
  • Altimetry, salinity, currents + heavy temp/colour-range customisation
  • The serious US canyon / tournament crowd
Where Fishare is different
  • Turn all that raw data into an answer. RipCharts hands you the satellite layers and the tools to read them; Fishare’s HSI is a per-species habitat model that fuses SST + thermal fronts + the shelf break + eddies into one fish-here score.
  • A bite score from a neural net trained on millions of real catches — RipCharts has no scoring or species layer at all.
  • A whole free forecast app around it: wind, swell, tide, currents, AIS, closures, a 14-day slider. RipCharts is imagery, not a trip forecast.
  • Browse free; pay only for the HSI layer. No US$169.99 annual-only wall to see anything.

When you should stay with RipCharts

What Fishare doesn't do (yet or by design)

RipCharts is for the expert who wants the raw ocean data and the tools to interpret it. Fishare is for the angler who wants the model’s answer — where the habitat for this species is today. If reading subsurface SST and altimetry by hand is your edge, keep RipCharts. If you would rather a model did that synthesis for you, inside a full free forecast app, that is us.

Last reviewed · May 2026

RipCharts ships the deepest raw satellite-imagery stack in offshore fishing — and expects you to read it. Fishare does not out-imagery them; it models the habitat for you. Raw data + expert interpretation (them) vs a per-species suitability model (us).

RipCharts is a pro instrument: raw and composite SST, cloud-free mashups, sub-surface SST at four depths, altimetry, salinity and 4–12 updates a day, with fine-grained temperature-range tuning so an experienced canyon angler can tease out a half-degree break. That depth is real and we do not pretend to match it. The question is what you want to do with it. RipCharts gives you the ingredients and a very good knife. Fishare’s HSI gives you the dish — it fuses SST, the thermal front, the shelf-break slope and mesoscale eddies into a single per-species habitat score, so the map says fish here for yellowfin today instead of here is the raw temperature field, work it out.

Pricing & tiers

RipCharts's pricing structure. Fishare is free across the board today (no paid tier yet — when one ships, current users get grandfathered).

RipCharts
Premium
US$169.99/yr (annual only)
  • All imagery datasets — raw/composite/sub-surface SST, chlorophyll, altimetry, salinity, currents, bathymetry. No monthly option, no free look at the data.

Pricing verified May 2026 against the RipCharts App Store listing + ripcharts.com. Annual-only; the data is gated behind the subscription, so you cannot sample the imagery free.

Fishare
Free
$0
  • Full forecast, map, spot pages, species pages
  • No paywall on any feature today
  • Optional account for catch logging + push alerts

When the paid tier launches (currently deferred), users who signed up before launch get lifetime access at the free tier.

Honest limitations

Limitations of RipCharts 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.

You do the interpretation

RipCharts shows a 24.1°C break tightening against the 100-fathom line. Whether that is a yellowfin edge today — and how the shelf-break slope and the nearest warm-core eddy change that — is on you. The synthesis, the actual fishing decision, is manual.

No species or bite layer

It is satellite imagery, full stop. There is no per-species suitability and no catch-trained scoring. Two anglers reading the same RipCharts map can reach opposite conclusions; the model is in their heads.

Annual-only paywall, US-centric

US$169.99/yr with no monthly option and no free look at the data. Coverage and the community are built around US offshore — less relevant elsewhere.

Who should pick which

Use-case routing — diplomatic, not flippant. Each row names a specific angler profile and the better tool for that profile.

US canyon / tournament angler who reads raw SST + altimetry by hand
→ RipCharts

Sub-surface SST, altimetry and 4–12×/day updates are the entire edge for that workflow.

Angler who wants where do I fish for this species today answered
→ Fishare

That is a model output, not a raw-imagery read — the HSI does the synthesis RipCharts leaves to you.

Anyone who wants a full forecast app around the offshore layer
→ Fishare

RipCharts is imagery only; Fishare is one canvas for the whole trip.

Budget-conscious or non-US angler
→ Fishare

Free forecast + a single HSI sub vs US$169.99/yr annual-only, US-centric.

Structural argument

RipCharts and Fishare sit at opposite ends of the same shelf: RipCharts maximises raw-data depth and hands interpretation to the expert; Fishare maximises synthesis and hands the angler an answer. A serious canyon crew could legitimately run both — RipCharts for the raw subsurface read, Fishare for the modelled per-species score and the rest of the forecast.

Migration

No clean migration — different jobs. If you have the experience to read raw subsurface SST and altimetry, RipCharts is a sharper instrument than our single daily HSI layer. If you would rather not, the HSI is the model doing that work for you.

Methodology & verification

Comparison verified May 2026 against the RipCharts App Store listing, ripcharts.com and the In The Spread satellite-mapping comparison. Feature depth assessed from their published dataset list; we credit their raw-imagery superiority explicitly rather than claim parity.

Frequently asked

Is Fishare really free?

Yes — the live map, bite score, 7-day forecast and spot pages are free to browse with no account. Logging catches and getting push notifications when peaks open requires a free account. There is no paid tier today.

How is Fishare different from RipCharts?

RipCharts is for the expert who wants the raw ocean data and the tools to interpret it. Fishare is for the angler who wants the model’s answer — where the habitat for this species is today. If reading subsurface SST and altimetry by hand is your edge, keep RipCharts. If you would rather a model did that synthesis for you, inside a full free forecast app, that is us.

Where does the Fishare bite score come from?

A multi-input neural network trained on millions of real catches across over 1,000 species — not a Solunar lookup. Inputs include wind, swell, tide stage, where the warm-cold water edges are, what the current is doing, moon phase, and a couple of dozen other features per hour. The model has been validated against catch data we held back from training. The catches keep coming in, so the model keeps getting sharper.

Does Fishare have an iOS or Android app?

Fishare is a Progressive Web App (PWA) — open fishare.app in mobile Safari or Chrome, then 'Add to Home Screen'. It runs offline, sends push notifications, and stays in sync without an app-store install. Native iOS / Android builds are on the roadmap.

When was this RipCharts vs Fishare comparison last reviewed?
