User-entered administration records
Injection Site Tracker for iPhone and iPad
PeptideCalc lets you attach a built-in or custom administration site to a dose log and review last-used hints and site history later.
The tracker preserves the location information you choose alongside the rest of your dose record. It does not recommend anatomy, choose an injection site, or set a rotation interval.

What it does
Injection-site records without site recommendations

Select from the administration sites included for the applicable medication form when you record a dose.
Custom administration sites
Create and name custom sites, then make them available for the medication forms you select.
Last-used hints
Review last-used context when choosing a site without asking the app to decide where or when you should inject.
Site history
Revisit the sites attached to prior dose logs and see site-related activity within schedule details and history.
Optional iCloud sync
Optionally sync supported injection-site and dose-log data across your signed-in Apple devices through iCloud.
How site tracking works
- 1
Use a built-in or custom site
Select an existing administration site, or create a custom site with the name and applicability you choose.
- 2
Attach it to your dose log
Choose the site while recording the dose so it is saved with the rest of that user-entered log.
- 3
Review the history later
Use prior dose records, site history, and last-used hints as a factual record of what you previously entered.
Scope and limitations
What the app does not decide
- The app records the administration site you select; it does not tell you which body area is appropriate for a medication.
- Last-used hints and history describe prior entries. They are not a recommendation for site rotation or a rotation interval.
- Custom site names and their applicability are defined by the user, not validated as medical instructions by PeptideCalc.
- iCloud sync is optional and applies only to supported app data. App analytics and crash or diagnostic reporting are described in the Privacy Policy.
Frequently asked questions
What does the PeptideCalc injection site tracker record?
It records the built-in or custom administration site you select for a dose log and lets you review that site information in history and schedule details.

Yes. You can name a custom administration site and choose the medication forms for which it should appear, then select it when logging a dose.
Does PeptideCalc recommend where I should inject?
No. PeptideCalc does not recommend anatomy, injection sites, or rotation intervals. It only records the site choices and dose information you enter.

Last-used hints summarize site information from prior records so you can see what you previously entered; they are not medical or rotation guidance.
