Rotate, explained.

Why rotation is worth an app

When infusion sites, sensors, or injections land in the same spots again and again, the tissue underneath quietly toughens — and well-rested skin simply works better. Everyone knows this; nobody can actually remember seventeen sites ago at 7am on a school day. Rotate’s whole job is to be that memory: tap where a site went, and the map keeps score so every spot gets the vacation it needs. (As always: your care team decides which sites are right for your kid — Rotate just remembers what happened where.)

Getting set up

1. Join the Family Pass at patreon.com/nohitterlabs — the same membership that covers Brave and everything else we make.
2. Open rotate.nohitterlabs.com and tap Sign in with Patreon. Once per device, good for about a month.
3. Install it: iPhone/iPad — Share button, then “Add to Home Screen.” Android — menu (⋮), then “Add to home screen.” It works offline after that.

The three tabs

Across the top: Pump site, Injection, and CGM. Each is tracked completely separately, because a spot that just finished hosting a sensor is a different question from one that hosted an infusion set. Use whichever tabs match your kid’s therapy and ignore the rest.

The body map

The map shows a dozen zones, front and back — arms, belly, hips, thighs, and friends. Every zone wears a traffic-light color: green means rested and ready, amber means still settling, red means recently used. A quick glance answers “where hasn’t been touched lately?” before anyone’s even fully awake. If your family uses colorblind-friendly mode (in Settings), the zones carry symbols too.

Logging a site

Tap the zone, and a card slides up showing that zone’s recent history. Add an optional note (“left side, near the freckle”), snap an optional photo if precision matters to you, and hit the log button. Done — two taps on a normal day. Made a mistake? The toast that appears has an Undo button, and the zone card also lets you remove an entry. You can also mark a zone as avoid — for spots your care team has ruled out or your kid simply hates — and it’s excluded from suggestions until you say otherwise.

“Where next?”

The banner at the top always has a suggestion: the zone that’s been rested longest, with a plain-words why. It’s a recommendation, never a rule — real bodies, real preferences, and real wardrobe logistics outrank the algorithm, and the app knows it. Under the hood it uses your settings for how many days a zone needs to settle and when it counts as fully ready, plus your device wear times (how long a pump site or sensor stays on) — all adjustable in Settings to match your care team’s guidance.

More than one kid? More than one anything.

Settings has profiles — add one per kid (or one per adult; plenty of grown-ups use Rotate for themselves). Each profile keeps its own logs, zones, settings, and language. The whole app is bilingual — English and Español — per profile, and there’s a dark mode for the 2am crowd.

The endo report

Before an appointment, tap the report button. Rotate assembles a clean, printable rotation history — which zones, how often, how recently, per therapy type. Print it, save it as a PDF from the print dialog, or just hand your phone across the desk. It’s the difference between “we move it around, mostly” and showing receipts.

Your data: synced sites, private photos, real backups

Because remembering is Rotate’s entire job, your rotation history follows your Family Pass: sign in on any device and your sites, notes, profiles, zones, and settings are there — log a site on mom’s phone and it shows on dad’s, automatically, a couple of seconds later. Deleting a mis-logged entry removes it everywhere too. One deliberate exception: photos never leave the device they were taken on. They’re the most personal thing in the app, so they stay put, period. On top of sync, each device asks the browser for protected storage and keeps a mirrored on-device copy, and Settings still has Download a backup / Restore from a backup for the belt-and-suspenders crowd (backups are also the only way photos can move to a new device, if you ever want that).

Troubleshooting

Sign-in screen came back: monthly session expired — tap Sign in with Patreon, ten seconds, done. Signing in bounced me to Brave’s page or nothing happened: close all Rotate tabs and reopen — you likely have an older cached version, and one fresh launch fixes it. Zone colors look wrong: check the settle/ready day settings match your expectations, and remember each tab tracks separately. Switching devices: just sign in on the new one — your history syncs down by itself (add a backup-restore only if you want photos to come along). Anything else: the contact page goes straight to the builder.
