We respect what RipCharts does well. Here is exactly where we're different and where we're not.
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.
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.
A factual head-to-head across the features that matter for the fishing-decision use case.
| Feature | RipCharts | Fishare |
|---|---|---|
| Raw / composite SST imagery | Yes — raw scans, 1/3-day composites, cloud-free | Gap-filled MUR SST under the hood (not shown as raw imagery) |
| Sub-surface SST (0/-25/-50/-100 m) | Yes | No — surface-driven habitat model |
| SST update frequency | 4–12 ×/day | Once daily |
| Altimetry / salinity layers | Yes | No (eddy structure via the AVISO atlas instead) |
| Per-species habitat model | No — you read the raw data | Yes — HSI scores SST + front + shelf-break + eddy per species |
| Bite score from real catches | No | Yes — neural net on millions of catches, 1,000+ species |
| Front + shelf-break detection | Manual (you tune the ranges) | Automatic — modelled into the score |
| Full forecast app (wind/swell/tide/AIS) | No — imagery focus | Yes — one canvas, 14-day slider |
| Coverage | US-centric | AU east coast live; US East + Gulf rolling out |
| Free tier | None — annual sub to see data | Forever-free forecast; HSI is the paid layer |
| Price | US$169.99/yr (annual only) | Free + a single HSI subscription |
RipCharts's pricing structure. Fishare is free across the board today (no paid tier yet — when one ships, current users get grandfathered).
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.
When the paid tier launches (currently deferred), users who signed up before launch get lifetime access at the free tier.
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.
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.
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.
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.
Use-case routing — diplomatic, not flippant. Each row names a specific angler profile and the better tool for that profile.
Sub-surface SST, altimetry and 4–12×/day updates are the entire edge for that workflow.
That is a model output, not a raw-imagery read — the HSI does the synthesis RipCharts leaves to you.
RipCharts is imagery only; Fishare is one canvas for the whole trip.
Free forecast + a single HSI sub vs US$169.99/yr annual-only, US-centric.
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.
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.
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.
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.

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.
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.
May 2026. We re-verify pricing, feature parity and known limitations each time a major version of RipCharts ships or pricing tiers change. The reviewed date at the top of the page is the source of truth.
They reflect the version of RipCharts 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. Free forever for everyone who joins now.
