SiteBuddy is an iPhone app that keeps a personal log of insulin-pump site rotation. You log where each pod goes, which way it points, when it went on and how long you plan to wear it. SiteBuddy shows the current pod with a countdown to its planned change, and your recent sites on a front and back body map.

SiteBuddy doesn’t connect to any pump, pod or controller: you log each pod yourself. It is built first for Omnipod: its site list and its directions start from Insulet’s placement guidance for pods, and the sites that guidance doesn’t name are labelled “Off-label”.

You can also use it to log the infusion sets of a tubed pump, but the sites and directions are tuned for Omnipod, and the app calls every placement a pod.

No. SiteBuddy is a personal log, not a medical device, and it does not give medical advice, diagnosis or treatment. Always follow your care team’s guidance and your pod’s instructions for use. Your pump system’s own alerts remain the reference for pod changes. The medical disclaimer has the details.

An iPhone with iOS 26 or later. SiteBuddy isn’t on the App Store yet: it’s coming soon.

Only on your iPhone, in SiteBuddy’s own storage. There is no account, the app makes no network requests, and it contains no analytics, ads or third-party code. The privacy policy has the details.

Deleting SiteBuddy deletes its data from your iPhone. There is no sync and no account, so the developer has no copy to restore.

If you back up your iPhone with iCloud Backup or to a computer, those backups include SiteBuddy’s data, as they do for other apps.

• Log a pod from the Pod tab, or with the + button in History. Change pod logs the new pod and ends the current one for you.
• Edit the current pod from the Pod tab, or any pod by tapping it in History.
• Mark as removed ends the current pod when you take it off without putting on a new one.
• Delete a pod while you edit it, or by swiping it in History. SiteBuddy asks first.

In Settings → Body sites. Sites are grouped by region, and every site has a switch, with “Off-label” and “Adults only” labels where they apply. The summary says how many sites are shown, and Restore defaults brings back the original selection. At least one site always stays shown.

Hidden sites are only left out when you log a pod: the pods you logged at them stay in your history, on its map too.

Listed by Omnipod

The site is in an area Insulet’s placement guidance names: the back of the upper arm, the belly and its sides, the front and outer thigh, the lower back (for adults only, in Omnipod 5 material) and the upper buttocks. The lower front thigh has this label too, though it lies below the area Omnipod illustrates, as its description says.

Off-label

No Insulet document or clinical guideline reviewed for SiteBuddy names the area, but some wearers report using it: the chest, the upper back and the calves. The upper back and calves start hidden. When you choose one, SiteBuddy notes: “Off-label site: talk to your care team before using it.”

Non-standard

A direction Omnipod doesn’t describe for the site. On the front thigh, Omnipod describes up or down; inward and outward stay selectable there, marked “Non-standard”.

Your site

A site you added. SiteBuddy has no guidance for it.

The labels summarize public information to help you have an informed conversation with your care team. They are not recommendations, and they never block a choice.

A direction is where the cannula end of the pod points: the end with the viewing window. Directions are relative to the body:

• Up: toward the head.
• Down: toward the feet.
• Inward: toward the body’s midline, the navel or breastbone on the front and the spine on the back.
• Outward: away from the midline.

On the side / hip, inward points toward the navel and outward toward the spine.

When you log a pod, the directions Insulet describes for the site come first and one is pre-selected: up on the arms and legs, inward on the trunk. The off-label chest, upper back and calves follow the same rule by analogy. A site of your own in the middle of the body offers up and down only.

When a wear time is longer than 80 hours, SiteBuddy shows this note when you log or edit a pod, and in Settings: “Omnipod pods stop delivering insulin 80 hours after activation.”

It is information only. SiteBuddy’s countdown follows the wear time you plan, and your pump system’s own alerts remain the reference for pod changes.

In Settings → Body sites, or with Add a site in the site list while you log a pod.

1. Give the site a name.
2. Tap where it is on the front or back of the body map, and drag the pin to adjust it. Move to a site puts the pin on a built-in site, and the arrow buttons, or VoiceOver’s actions on the pin, move it a step at a time.
3. Choose the directions you log there: up and down, inward and outward, or both.

While you place it, SiteBuddy says which side of the body the site is on and which site is nearest, and warns when it sits so close to another site that a tap can’t tell them apart.

Your sites are labelled “Your site”. Rename, move, hide or delete them in Settings → Body sites. Deleting a site keeps its pods in your history, with its name, marked “Deleted site”.

English and Italian. SiteBuddy follows your iPhone’s language, including plurals, dates and VoiceOver. Other languages show English.

SiteBuddy supports VoiceOver, Voice Control and Switch Control, Dynamic Type (list rows stack at accessibility sizes), Dark Mode, Increase Contrast and Reduce Motion, with WCAG AA contrast in both appearances.

Its own controls are at least 44 points tall. Body-map sites that sit close together get smaller targets, which is why a tap in the full view zooms in on them first; VoiceOver, Switch Control and Voice Control always choose a site directly, and every site can also be chosen from a searchable list.
