SiteBuddy

SiteBuddy

A personal log of insulin-pump site rotation for iPhone, built first for Omnipod® wearers.

It records where each pod goes and which way it points, and shows your recent sites on a front and back body map.

Why SiteBuddy

Where did the last few pods go?

Rotating sites is part of living with an insulin pump. Using the same spot too often can irritate the skin and lead to lipohypertrophy, a lumpy thickening under the skin that can make insulin absorption less predictable. With a pod changed every few days, “where did the last ones go?” is hard to answer from memory.

Omnipod adds a twist. Insulet lists the back of the upper arm, the belly and its sides, the front and outer thigh, the lower back (for adults, in Omnipod 5 material) and the upper buttocks as pod sites, and wearers also vary the direction a pod points. SiteBuddy records both, so your history shows which spots, and which directions, you have used recently.

Log a pod

A new pod, logged in a few taps

Pick the site on the body map or from a list, choose the direction the pod points, and confirm the date and wear time.

  • The date starts at now and the wear time at your usual one: 3 days (72 hours) unless you change it in Settings. Any wear time from 1 hour to 14 days can be set.
  • On the whole-body map, a tap on a site that sits close to others zooms in on it first, so the right one is easier to pick.
  • While you pick, the map shows how long ago each recently used site was last worn, and the site list says when each site was last worn.
  • Wear times over 80 hours show a note that Omnipod pods stop delivering insulin 80 hours after activation.
  • You can add a note to any pod.

Current pod

The current pod at a glance

The Current pod screen shows where the pod is and which way it points, when it went on, and a countdown to the change due by the wear time you planned, with your most recently used sites below.

Mark a pod as removed when you take it off without putting on a new one. Logging a new pod ends the current one for you.

The countdown follows the wear time you plan. SiteBuddy doesn’t connect to your pod, so your pump system’s own alerts remain the reference for pod changes.

The status of the current pod

  • On track

    Until the last 8 hours of the wear time you planned.

  • Change soon

    In those last 8 hours.

  • Overdue

    Past the planned change, with the time since: “Overdue by …”.

History

Your recent sites on a body map

Front and back views of the body, whole or zoomed to the upper or lower half, show your most recent sites: the last 5 pods by default, or as many as you choose. The newest are the strongest, and an arrow shows each pod’s direction.

Below the map, every pod is listed with its direction, how long it was worn and its note. Tap one to edit it, or swipe to delete it after a confirmation.

History, front of the body: the most recent pods as numbered markers, the newest strongest, each with an arrow for its direction. History, back of the body: the recent pods worn on the back of the arms and the lower body.

Body sites

An Omnipod‑first site catalog

28 built-in sites, 14 on each side, across the arms, chest, upper back, belly, sides, lower back, buttocks, thighs and calves, chosen from a fact-checked research brief. Each site says where exactly it is and carries a label:

Listed by Omnipod
The area is one that Insulet’s placement guidance names.
Off-label
Some wearers report using the area, but Insulet’s documents don’t name it: the chest, upper back and calves.

The labels inform; they never block a choice. When you log a pod, the directions Insulet describes come first and one is pre-selected: up on the arms and legs, inward on the trunk. On the front thigh, inward and outward stay selectable, marked “Non-standard”.

In Settings → Body sites, show or hide any site. The off-label upper back and calves start hidden, and hidden sites stay in your history.

Settings, Body sites: your own sites and a button to add one at the top, then the built-in sites grouped by region, each with a switch.

Your sites

Add the sites the catalog leaves out

Give a site a name, tap where it is on the front or back of the body map and drag the pin to adjust it, then choose the directions you log there. Your sites appear on every map and in every list, labelled Your site. SiteBuddy has no guidance for them.

Add one in Settings → Body sites, or straight from the site list while you log a pod. Rename, move, hide or delete them later: deleting a site keeps its pods, and its name, in your history.

Adding a site of your own: its name, a pin placed on the body map, its position in words, and arrows to fine-tune it.

Privacy

Everything stays on your iPhone

Not medical advice

SiteBuddy is a personal record-keeping tool. It is not a medical device, and it does not provide medical advice, diagnosis or treatment. It does not connect to, control or read from your pod, pump, controller or any other device.

  • Always follow the instructions of your diabetes care team and the instructions for use that came with your pod or infusion set, including where you may place it and how often you should rotate.
  • Site guidance labels (“Listed by Omnipod”, “Off-label”) summarize public information to help you have an informed conversation with your care team. They are not recommendations.
  • Do not rely on SiteBuddy for pod-change timing. Your pump system’s own alerts remain the reference.
  • If a site is red, swollen, painful or leaking, or your glucose is unexpectedly high, follow your care team’s advice. In an emergency, call your local emergency number.
