The big idea
What's the Pattern Engine, and why is it different from other fishing apps?
WaterWatcher's Pattern Engine learns what conditions produce fish at your specific spots — from your own catch history and from nearby anglers — and tells you when today matches your past banner days. Every fisherman has those days they remember — the day at the canal when water temp was 64°F, falling tide, and the stripers wouldn't stop. Those days have patterns: water temperature, tide, wind, time of day, barometric pressure, moon phase. WaterWatcher captures the conditions for every catch you log, then watches the forecast for days that match. When today resembles one of your banner days, we tell you. We do the same with catches from anglers nearby — anonymously — so even brand-new users benefit. Most fishing apps give you data and let you figure it out. WaterWatcher tells you what the data means for you.
Pattern Engine
When does WaterWatcher fire a strong-match alert?+
A strong match fires when today's conditions — water temperature, tide, pressure trend, wind, time of day, moon phase, and more — closely align with the conditions from your past successful days at that spot, or with productive days from nearby anglers. We require both a high overall match score AND alignment on the signals that matter most for the species you're targeting. Alerts are limited to once every 4 days per spot, so you only hear from us when it's genuinely worth packing the gear.
How many trips do I need to log before patterns are useful?+
It's trips, not raw catches, that matter — distinct days matter more than catch count, since ten catches from one outing is really just one day's conditions, not ten independent observations. Personal patterns start to emerge after about 6 logged trips at the same spot. Around 10 trips, real patterns surface and predictions get noticeably tighter; by ~20, the engine reads today against your history with much less hedging. Skunked trips count too — a day you caught nothing is still a data point about which conditions don't produce. Until then, you still benefit from the local pattern library — anonymized trips from other anglers in your waters — so you're not starting from zero.
How it works
Does WaterWatcher run automatically?+
Yes. Set your spot, your delivery time, and your frequency once — every Friday at dawn, every morning, twice a day, whatever you choose. No logging in, no clicking, no reminders. THE READ is in your inbox when you wake up.
Does it work for freshwater spots?+
Yes — lakes, rivers, reservoirs, ponds, creeks, and canals. River reads include USGS real-time flow data. Lake reads check thermocline conditions and stocking updates. Bass, walleye, trout, salmon, pike, catfish — freshwater is fully supported.
Does it work outside the US?+
WaterWatcher is built primarily for US fishing spots, where data coverage is richest. International locations work — popular spots in Canada, the UK, Australia, and New Zealand have decent coverage — but we're transparent when sources are thin.
I fish a spot that's not on the map. Can I add it?+
Yes — use the "Suggest a spot" link. You'll find it at the bottom of the spot picker map when checking conditions or adding a new spot, and under Settings → Spots. Drop a pin on the location, give it the name anglers actually call it, and select the species you typically catch there. Water type is detected automatically from the pin location, so there's nothing to configure. Suggestions go through a quick review before they're added — your spot won't appear on the map immediately, but once it's approved it'll show up as a named location for everyone. Most reviews happen within a few days.
Your reads & data
How does THE READ work?+
THE READ synthesizes tide stage, solunar period, wind, dawn/dusk, and barometric pressure — weighted against your own trip history at that spot — into specific feeding windows for the next 48 hours, ranked hot / good / fair / slow. You see exactly when to be on the water, not just general "conditions are favorable" hedging.
Can I choose when my read is delivered?+
Yes — Signal and Pro plans let you set any delivery time and timezone. Most anglers choose dawn (5am) so the email is waiting when they wake up, or evening (6pm) to plan the next morning's trip. Scheduled delivery requires a paid plan; Logbook is on-demand only.
Can I get a read on demand?+
Yes — Signal and Pro subscribers can generate a read on demand from the dashboard at any time. Logbook is limited to 2 reads per month.
Can I get reads for multiple spots?+
Yes. Signal subscribers can add up to 6 spots, each with its own delivery schedule. Pro gets unlimited spots — useful for anglers who fish multiple locations or split time between a lake cabin and the coast.
What does my read history show me?+
As your reads accumulate, the history page builds a picture of patterns at your spots — which months are most active, which species appear most, water temperature trends, and seasonal patterns we detect automatically. The longer you use WaterWatcher, the sharper it gets.
Plans & billing
Is there really a free plan?+
Yes — the Logbook plan is free forever, no credit card. You get two fishing spots and two condition reads per month, on demand. Signal and Pro add scheduled automatic delivery and unlimited reads. Paid plans (Signal $8.99/mo, Pro $16.99/mo) include a 30-day free trial — your card is collected at signup but not charged until day 31. Cancel any time before that and pay nothing.
Can I cancel anytime?+
Yes. Cancel any time from the billing settings page — no phone call, no retention flow, just a button. Your plan stays active until the end of the billing period you've already paid for, then reverts to the Logbook plan. You keep your account and read history.
Do you offer refunds?+
If you cancel within 48 hours of a charge and haven't used the service that period, email support@waterwatcher.com and we'll refund it. Outside that window we don't offer refunds, but cancellation is always instant and there are no long-term contracts.
Is there a discount for annual billing?+
Yes — annual billing gets you 2 months free on both Signal and Pro plans. Signal annual is $89.99/yr (vs $107.88/yr monthly). Pro annual is $169.99/yr (vs $203.88/yr monthly).
Can I pause my subscription during the off-season?+
Not yet — but it's coming. In the meantime, you can cancel and resubscribe when the season picks back up; your spots and preferences are saved. Seasonal pause is high on our roadmap.
Conservation & the Ledger
What is the WaterWatcher Ledger?+
The WaterWatcher Ledger is our conservation data program. Every opted-in trip contributes structured observation data — species, size, conditions, water clarity, bait presence, wildlife sightings — to a growing pool of citizen science data shared with fisheries conservation organizations. It's what makes WaterWatcher more than a fishing tool: a platform for anglers who care about protecting the resource they fish.
How does my data contribute to conservation?+
When you opt in to the community pool, each trip you log contributes anonymized catch and observation data to the Ledger. Conservation science partners working to protect saltwater fisheries receive quarterly data briefs aggregated from it — species distribution, size structure, conditions correlations, and observational data like bait presence and wildlife sightings. Your name, exact location, and any identifying information are never shared.
Do I have to share my data with conservation partners?+
No — participation is always opt-in. You choose whether each trip contributes to the community pool, and you can change that setting at any time. Opting out doesn't affect your personal Pattern Engine, your reports, or any other feature.
Is conservation data contribution available on the free plan?+
Yes. Logbook users who opt in contribute identically to paid subscribers. Conservation data isn't paywalled — if you care about the fishery, you contribute regardless of your plan. The value of the Ledger is in the depth and breadth of observations, not in who's paying.
Privacy
What data do you collect?+
First and foremost: we do not sell your data, and we do not share your exact fishing spots or catch locations. Spot burning isn't our business — we're anglers ourselves, and we know what that trust means. What we actually collect: your email, the fishing spots you add for constructing your journal and condition reads, your delivery preferences, and the condition reads we generate for you. See our Privacy Policy for the full picture. The one exception, and it's entirely your call: if you catch a tagged fish, you can choose to share your real location and contact info with the relevant conservation organization to help with tag recapture — but only if you opt in for that specific catch. Nothing is shared without your explicit say-so, every time.
How does the community pattern library work, and what's shared?+
Every trip you log — catches and skunks alike — feeds your personal Pattern Engine. With your permission, anonymized catch conditions also feed a community pattern library, which helps anglers fishing in your waters get better predictions even before they've logged many catches themselves. We never share your name, your exact spot, or any identifying information — just generalized conditions tied to a rough geographic area. You can opt out any time in your privacy settings, and your existing personal patterns are unaffected either way. Opted-in data also contributes to the WaterWatcher Ledger — our conservation data program. Learn more at waterwatcher.com/conservation.
Is my payment information secure?+
We never see your card details. All payment processing is handled by Stripe, which is PCI-DSS Level 1 certified — the highest level of payment security. Your card number never touches our servers.
Can I delete my account and data?+
Yes. Email support@waterwatcher.com with a deletion request and we'll permanently remove your account, spots, and all generated reads within 7 days. Or use the account deletion option in Settings.
