Lowrance: app for anglers

Review by eFreeware

If you already fish from a boat with a Lowrance chartplotter on the console, this companion app is the piece that keeps your planning and your on-water electronics talking to each other. It puts C-MAP charting on your phone, lets you build and store waypoints away from the boat, and syncs that work back to the unit when you step aboard. For an angler who marks spots, returns to them season after season and wants the next trip mapped out before leaving the dock, that combination is the appeal.

The download is free, with ads and in-app purchases, and the app has been installed more than 500,000 times with a 4.0 average from 3,696 ratings. It first appeared in November 2019 and has been updated since. Those numbers tell me it has found a settled audience rather than a passing one, though the rating also suggests the experience is not flawless for everyone.

Charts, spots and the planning side

The charting comes from C-MAP, and the developer describes the maps as detailed and accurate, with fine depth detail, custom shading and thousands of points of interest covering ramps, fuel, marinas, harbors, beaches and shops. Depth contours and shading are the sort of detail that matters when you are trying to hold a boat over structure, and having ramps and fuel stops marked saves a separate search before a launch.

Planning is built around waypoints. You can create, store, edit and share fishing spots from wherever you happen to be, which means a mark taken on a whim can be tidied up later at home. Autorouting takes a set of those waypoints and works out a route to them, and a measure distance tool rounds out the chart tools. A free C-MAP chart viewer is included, so the basic map view does not sit behind the upgrade.

GPX import and export is the quiet workhorse here. Routes, tracks and waypoints move in and out of the app in a format other software understands, so you can hand a set of marks to a friend or bring in a file they sent you. Anyone who has ever retyped coordinates from a message thread will see the point.

Weather before you commit to a day

Marine weather is treated as a first-class feature rather than an afterthought. There is a forecast, a view of conditions along a planned route, and a weather overlay you can lay over the chart. For trip planning, that combination is more useful than a generic forecast, because it answers the question an angler actually asks: what will it be like on the water between here and there.

The overlay matters most when you are deciding whether a run is sensible. Seeing conditions drawn over the same chart as your route and waypoints keeps the decision in one place instead of bouncing between a chart and a weather page. I would treat this as the planning half of the app, the part you use the night before rather than the part you use at the helm.

Syncing with the boat and staying put

The sync story is what separates this from a standalone chart viewer. Waypoints, spots and trip data move between the app and your Lowrance devices when you come aboard, and the same sync works on or off the water, so the latest trip data travels with you. Chartplotter activation and registration are handled in the app as well, which folds a chore into the same place you keep your marks.

Anchor alerts and location notifications cover the other end of a day. You set a boundary and get told when the boat drifts outside it. That is a narrow feature, but it is the kind of narrow feature that suits a boat where someone is watching a rod rather than a screen.

What the Premium upgrade changes

The free app is not the whole picture. Premium adds full GPS functionality, offline map downloads, REVEAL shaded relief, high-resolution bathymetry, custom depth shading, and AIS with C-MAP traffic. Offline charts are the one that changes how the app behaves: with them downloaded, you can view your data without mobile coverage or WiFi, which is the normal state of affairs on plenty of water.

It is billed as something you can try before committing, with a 14-day free trial, shortened to three days in Denmark and Sweden. Full GPS functionality is part of the Premium upgrade. Whether the upgrade earns its cost depends on how much you rely on relief shading, depth shading and traffic information, and that is a judgment each angler makes against their own water.

Hardware requirements and the honest trade-offs

Direct integration with a chartplotter is conditional. It needs NOS software version 20.0 or above, and the developer lists the supported models as Elite ti2, Elite FS, HDS Carbon, HDS Live and HDS Pro. If your unit is not on that list, or its software is older, the sync features that make this app distinctive are not going to work for you. Checking that before installing is the sensible first step.

The other trade-offs are structural rather than hidden. The app is free to download but carries ads and in-app purchases, and several of the capabilities an angler would reach for on the water sit in the Premium tier. That is a reasonable model for a companion app.

There is also the question of focus. This is an app built around C-MAP charting, waypoints, routes and Lowrance hardware, not a general-purpose boating or outdoors tool. Its usefulness scales with how much of that ecosystem you already own and use.

Who gets the most from it

The clearest fit is an angler running a compatible Lowrance chartplotter who wants marks, routes and trip data organized on a phone and carried back to the boat. If you plan trips in advance, keep a mental or written list of spots, and care about depth detail and weather on the route, the app is built around exactly those habits.

It also suits someone who shares marks with fishing partners, since waypoints and GPX files can be passed around. And it suits the angler who wants to register and activate a chartplotter without hunting through menus on the unit itself.

For anyone without Lowrance hardware on board, the picture is different. The chart viewer, points of interest and weather still stand on their own, but the sync features that give the app its character have nothing to connect to. That is not a flaw in the app so much as a boundary of what it was made for.

A companion worth having on a Lowrance boat

I would judge this as a well-scoped companion app rather than a standalone navigation package. It does the planning jobs well on the evidence of what it offers: C-MAP charts with depth detail, waypoint management with sharing, Autorouting, route weather and a sync path to the boat. The Premium upgrade adds additional features.

The conditions are worth restating once. You need a compatible chartplotter running NOS 20.0 or above to get the integration, and the features an angler leans on at the helm sit in the paid tier, with ads and purchases present in the free app. The 4.0 average from a large body of ratings suggests most users find it workable, without it being universally loved.

If you own one of the listed Lowrance units and want your spots, routes and weather in one place on your phone, this is an easy install. If you do not, the app still offers charting and planning, but the reason to choose it over a plain chart viewer is missing.
