Record the injection site with each logged dose on a body map, see when each site was last used, and review the history per protocol. Updated August 2026.
Important
This page is informational. BodyDex is a tracking tool, not a medical device. We don't prescribe, source, sell, or recommend any medication, and nothing here is medical advice or injection instruction. Your healthcare provider's instructions on where and how to inject always come first. Follow your local laws.
The short answer
BodyDex on iPhone and Android records the injection site with every dose you log. Pick the site on a body map, see when each site was last used, and review the full site history per protocol. The field is optional and editable, and your healthcare provider's instructions on where and how to inject always come first. It works for any injectable your healthcare provider prescribed — GLP-1 pens, insulin, peptides — alongside dose reminders, supply forecasting, and your food log, all stored on-device.

What an injection-site log records
A site with every dose
The whole point of a rotation log is the record. In BodyDex, every logged dose of an injectable protocol can carry an injection site, saved together with the timestamped entry — so "where did I do last week's dose?" has a real answer instead of a guess.
A body map, not a memory test
Instead of a text dropdown, BodyDex shows a body silhouette with tappable zones. You tap the spot you used and the app records it with the dose, saved together with the timestamped entry.
Shows what you used recently
When you open the site picker, zones you've logged recently are marked on the map along with how many times you've used them. BodyDex also remembers the last site you logged for each protocol, and every past dose in your history shows its site — three ways to see where you've been.
Optional, and editable after the fact
The site field is optional — a dose always logs fine without one. Add the site when it's relevant, skip it when it isn't, and edit a past entry if you tapped the wrong zone. The label is part of your record.
Every injectable in one app
BodyDex isn't a single-drug app. The protocol model is generic — GLP-1 pens, insulin, peptides, or any other injectable your healthcare provider prescribed — and each protocol keeps its own site history alongside its dose log.
On-device storage with export
Your injection history is sensitive. BodyDex keeps it in a local SQLite database on your phone — there is no centralized BodyDex database of your doses or sites — and you can export everything as JSON or CSV from Profile → Export Data.
How to log an injection site in BodyDex
1Set up the injectable protocol
On the Home tab, swipe to the Protocols panel, tap Peptides & Meds, then Add Protocol. Choose an injectable form when you set it up — that's what makes the injection-site picker appear when you log doses.
2Open Log Dose
Log a dose from the protocol card, or straight from the dose reminder when it fires. Injectable protocols show an Injection Site card on the logging screen.
3Tap the Injection Site card
The body map opens with front and back views. Tap the zone you used — the site is saved as part of your log entry.
4Pick the zone you used
Recently used zones are marked on the map with how many times you've logged them, and BodyDex preselects the last site you logged for this protocol — so repeat logging is one glance and one tap.
5Save the dose
The site is stored with the timestamped dose entry. Picking a site is optional — a dose logs fine without one, and you can add or change the site later by editing the entry.
6Review your site history
Every past dose in your dose history shows the site it was logged with, per protocol — your site history, in order, whenever you want to check it.
FAQ
Is BodyDex a medical device?
No. BodyDex is a tracking and journaling tool. It does not diagnose, treat, prevent, or cure any condition, and it does not provide medical advice. Always work with your prescribing clinician on doses, schedules, and how and where to inject.
Does BodyDex tell me where to inject?
BodyDex records the site with your dose and shows your history — which site you used last, how recently, and how often. It does not give medical advice or injection instructions: your healthcare provider's instructions on where and how to inject always come first.
What exactly does BodyDex record?
An optional site label, attached to the timestamped dose entry and picked on a body map rather than typed. The record is the label, the timestamp, and the protocol it belongs to — and you can change or remove the label by editing the entry.
Do I have to pick a site every time?
No — the site is optional. A dose always logs with its timestamp; add the site when it's relevant, skip it when it isn't, and edit a past entry if you tapped the wrong zone.
Which medications does this work with?
Any protocol you set up with an injectable form — GLP-1 pens, insulin, peptides, or any other injectable your healthcare provider prescribed. The protocol model is generic, not a preset drug list. Oral medications and supplements use the same dose log, just without the site picker.
Can I see which site I used last?
Yes, three ways: the body map marks recently used zones (with use counts) when you log, BodyDex preselects the last site you logged for that protocol, and every past dose in your history shows the site it was logged with.
Does BodyDex also remind me and track supply?
Yes. Once a schedule is set, BodyDex schedules local notifications for each dose, and supply forecasting counts down your remaining doses and warns before you run out — the site record is one part of a full dose log, not a separate app.
Is injection site tracking free?
Yes. It's part of dose logging, which is a free-tier feature — the free tier covers up to 2 active protocols per category (peptides, medications). Premium ($9.99/mo or $79.99/yr, with a 7-day trial) removes the cap and adds AI food scanning and the AI coach.
Where is my injection history stored?
On your device, in a local SQLite database — there is no centralized BodyDex database of your doses or sites. On iOS, iCloud backup (if you use it) is at the OS level and follows Apple's standard encryption posture; on Android, BodyDex opts out of OS backups entirely. You can export your data as JSON or CSV from Profile → Export Data.
