One app, three modes
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
Switching modes keeps your location and waypoints in place and swaps the layers, intelligence, and regulations underneath. Toggle it in a tap.
01 · Driftline
The water side of the app. Real-time river flow (CFS) for 1,300+ rivers across 38 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.
02 · Ridgeline
The field side of the app. 1,300+ hunting units across 11 Western states (WA, OR, ID, MT, CO, WY, UT, AZ, NM, NV, CA), land ownership down to the parcel, public vs private boundaries, full season dates and regulations by unit for WA, OR, ID, and MT, controlled-hunt draw odds, weather and thermal layers, and offline topo for the backcountry.
03 · Forage
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.
How the names fit together
| 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
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.
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.
