The fishing motion journal

Tape an AirPod to your rod. See your casts.

RodPod reads the motion of one AirPod on your rod. Fish as usual, then look back at your estimated casts, how hard you cast and how the rod moved.

iPhone with iOS 17 or later · AirPods that provide motion · Free, 10 minutes per session

Setup

Five steps, then fish.

You need: an iPhone with iOS 17 or later, AirPods that provide motion, and some tape.

  1. Choose the bud.

    Pair your AirPods with your iPhone as usual. In RodPod, open AirPods & rod setup (from Settings, Start fishing or Rod alerts), allow Motion & Fitness and Microphone, then pick the AirPod that goes on the rod. Either side works.

    RodPod setup: “Which AirPod is on your rod?” with Left and Right buttons, Right selected.
  2. Change two iPhone settings.

    In Settings → Bluetooth, tap ⓘ next to your AirPods. Turn Automatic Ear Detection off and set Microphone to Always Right AirPod (or Left, to match). RodPod can't change these for you.

    RodPod setup: “Keep your rod AirPod connected.” Automatic Ear Detection: Off. Microphone: Always Right AirPod.
  3. Tape it to the rod.

    Put it on the blank just ahead of the grip, on the side, clear of the line and your thumb. One snug wrap of tape so it can't wobble. That's our field-test mount; others can work, and the mount affects the readings.

  4. Run the movement test.

    It starts on its own once your AirPods connect. Move the rod and keep the other AirPod still and out of your ear. Continue as soon as movement is verified; the test runs for up to six seconds.

  5. Start fishing.

    Tap Start fishing and fish as usual; there's nothing to narrate. Estimated casts appear as you cast. Tap Finish to save the outing and see its technique timeline.

    Live session, labelled demo replay: 4 estimated casts after 1:49 on the water, latest cast 11.0 g.

Run the test again whenever you change the AirPod, the rod or the mount. See the mount in 3D · Setup guide and troubleshooting

After the outing

What you'll look back on.

Real screens from our first outing: one recording. Casts and techniques are experimental estimates, not a benchmark.

  • Cast chart for the first outing: 10 estimated casts from 12:46 to 12:51, each bar its peak acceleration between about 9 and 12.6 g.

    Every cast

    When it happened, and how hard: peak acceleration at the AirPod, in g.

  • Experimental technique timeline: rows for linear retrieve, jigging, stop-and-go, around a cast, unclassified and signal gaps.

    Your retrieve

    Linear, jigging or stop-and-go: an experimental best guess.

  • Rod acceleration in g across the whole outing: ten tall spikes for the casts and lower motion between them.

    The whole outing

    Every move of the rod, the quiet bits too.

Second mode · Rod alerts

Resting the rod? It keeps watch.

Prop the rod on a rest, keep the other AirPod in your ear and set a sensitivity from 0 to 100. RodPod sounds when the rod moves more than that. An alert means the rod moved; it is not a bite detector.

10 free minutes per monitoring session. A call, lost connection or other audio interruption stops monitoring.

Rod alerts screen: “A little movement. A heads-up.”, with a sensitivity slider set to 59 of 100 and +/− buttons.

Good to know

Honest about what it knows.

  • Casts are estimates. RodPod can miss casts or count other vigorous movement as a cast. Handling gear can look like a retrieve, and quiet motion does not mean you stopped fishing.
  • An alert is not a bite. It means the rod moved: a fish, wind, the line or a bump. RodPod does not detect bites, tangles or catches.
  • “g” is not distance. Cast intensity is peak acceleration at the AirPod. It is not distance, force, line tension or skill. Compare casts within one outing using the same mount.
  • Check before a locked-phone session. Uninterrupted recording, including with the phone locked, is not guaranteed yet. Run the setup check before each outing and check that motion is being received.
  • Your spot stays yours. Recordings are processed on your iPhone. There is no account, no upload of your fishing motion and no location access.
