Sunset over a Pacific Northwest river

One app, three modes

Baseline Maps is the app. Driftline, Ridgeline, and Forage are modes inside it.

Not three apps. Not three subscriptions. One outdoor app with three modes you switch between: Driftline for fishing, Ridgeline for hunting, Forage for foraging. The app was originally called Driftline.

In one sentence

Baseline Maps is a single outdoor app for iOS and Android. Inside it are three modes: Driftline (fishing and water), Ridgeline (hunting and backcountry), and Forage (foraging). They are modes, not separate apps. The app was first released as Driftline, then renamed Baseline Maps as it grew beyond fishing.

The modes

Same map. Same account. The data behind it changes with the mode.

Switching modes keeps your location and waypoints in place and swaps the layers, intelligence, and regulations underneath. Toggle it in a tap.

Driftline

Fishing & water

The water side of the app. Real-time river flow (CFS) for 1,100+ rivers across 13 US states plus British Columbia and Ontario, water temperature and gauge height, tides with solunar overlay, NOAA buoys, lake bathymetry, hatchery returns, and fishing regulations parsed by river and zone.

  • Live CFS, water temp, gauge height
  • Custom flow alerts per river
  • Tides, swell, wind, sea-surface temp
  • Catch logging with conditions

Ridgeline

Hunting & backcountry

The field side of the app. 1,339 hunting units across 9 Western states (WA, OR, ID, MT, CO, WY, UT, AZ, NM), land ownership down to the parcel, public vs private boundaries, season dates and regulations by unit, controlled-hunt draw odds, weather and thermal layers, and offline topo for the backcountry.

  • GMU boundaries, public-land overlay
  • Parcel-level ownership data
  • Season dates and regs by unit
  • Offline topo, hillshade, satellite

Forage

Foraging

The foraging side of the app. Burn-scar overlays for morel season, USFS forage-permit information, soil-temperature triggers for mushroom emergence, and the public-land layers that tell you where you can legally pick.

  • Burn-scar overlays for morels
  • USFS forage permit info
  • Soil-temperature triggers
  • Public-land boundaries

How the names fit together

One product. One subscription. One account.

Baseline Maps The app. One download on iOS and Android. Everything below lives inside it.
Driftline A mode inside Baseline Maps: fishing and water. Also the app's original name.
Ridgeline A mode inside Baseline Maps: hunting and backcountry.
Forage A mode inside Baseline Maps: foraging.
Driftline Co. The company that makes Baseline Maps.

There is no separate Driftline app, Ridgeline app, or Forage app. There are three modes, and they all open from the same Baseline Maps install.

Why two names

It started as Driftline. Then it outgrew the name.

The app first shipped as Driftline, a fishing-only tool built because checking the USGS website on a phone with cold fingers was miserable. It did one thing: real-time river and ocean conditions for anglers.

Then a hunter asked whether the same approach (live data, parsed regulations, clean maps) would work for GMUs and land ownership. It did. That became Ridgeline. Then a forager asked for burn scars and permits. That became Forage.

Once the app covered more than fishing, the name Driftline no longer described the whole thing. So the app was renamed Baseline Maps, an umbrella that fits everything it does now. Driftline did not go away. It became the name of the fishing mode. Ridgeline names the hunting mode, Forage names the foraging mode, and Baseline Maps is the app that holds all three.

The short version, for anyone still unsure.

Is Driftline a separate app?

No. It is the fishing mode inside Baseline Maps, and the app's former name.

Is Ridgeline a separate download?

No. It is the hunting mode inside the same Baseline Maps app.

How many apps do I install?

One. Baseline Maps. Every mode is inside it, on one subscription.

FAQ

Baseline Maps, Driftline, and Ridgeline.

Is Driftline a different app from Baseline Maps?
No. Driftline is not a separate app. Baseline Maps is the app; Driftline is the fishing mode inside it. The app was originally released under the name Driftline when it only did fishing. When it grew to cover hunting and more, the app was renamed Baseline Maps, and Driftline became the name of the fishing mode.
What are Driftline and Ridgeline?
Driftline and Ridgeline are modes inside the Baseline Maps app, not standalone products. Driftline is the fishing and water mode (river flows, tides, buoys, fishing regulations). Ridgeline is the hunting and backcountry mode (GMU maps, land ownership, hunting regulations, offline topo). You switch between them inside one app, on one subscription.
How many modes does Baseline Maps have?
Three: Driftline (fishing), Ridgeline (hunting), and Forage (foraging). They all live inside the same Baseline Maps app and share the same map, subscription, and account.
Do I need to download Driftline and Ridgeline separately?
No. There is one download: Baseline Maps, on the iOS App Store and Google Play. Every mode is included in that single app. There is no separate Driftline app, Ridgeline app, or Forage app to install.
Why does the App Store sometimes show the name Driftline?
The app launched as Driftline, so older or region-specific store listings and links may still show the original name (for example, "Driftline: Fish & Hunt Maps"). It is the same app. The current and canonical name is Baseline Maps.
Do the modes cost extra?
No. One subscription, $34.99 per year with a 30-day free trial, unlocks every mode. There are no per-mode charges, no per-state surcharges, and no tiers.
Is Driftline Co. the same as Baseline Maps?
Yes. Driftline Co. is the company; Baseline Maps is the app it makes. The company name predates the app rename and is unchanged.

One app. Every mode. $34.99 a year.

Driftline, Ridgeline, and Forage, all in Baseline Maps. Free for 30 days.
