Tracker: track your screenings, results and reminders
Tracker helps you keep track of your STI screenings simply, without sharing anything.
Log your results after each screening and let the app do the rest: it shows you how far back your results are reliable and reminds you when to test again.

Inside the app
What Tracker actually does
Screenings, window periods, reminders, treatments, information. Nothing else — and no data leaving your phone.
01/Screenings
Your screenings at a glance
One entry per screening, every infection you tested for, and a history you can read back in seconds.
Screenings
- HIV
- Syphilis
- Chlamydia
- Gonorrhea
- Hepatitis B
- Hepatitis C
- Record your results for HIV, syphilis, chlamydia, gonorrhea, and hepatitis B and C
- Browse the history of all your screenings
- Mark a result as “Pending” and update it later
02/Window periods
Window periods, made clear
Every test needs some time before it becomes reliable. For each result, Tracker shows which exposures are covered: conclusive or not reliable yet.
Conclusive
Exposures before this date are covered by the test.
Not reliable yet
Too early: this period is not covered by the test.
For each result, Tracker also says from when a new test would cover everything up to that screening.
03/Reminders
Reminders that fit your rhythm
Set the interval once and Tracker keeps the calendar — quietly, and only on your device.
- An automatic reminder every 3, 6 or 12 months after your last screening
- A follow-up nudge if you haven't done the next one yet
- Your own reminders, on the date of your choice
04/Treatments
Your treatments, day by day
A course of antibiotics is easier to finish when the app keeps the count for you.
- Check off each dose and follow your progress
- Get a reminder at the time of each dose
- Plan a follow-up test when the treatment ends
05/Learn
Info cards to understand
Symptoms, treatment, duration, the right time to get tested: clear information about the most common STIs.
06/Privacy
Your privacy first
There is no server behind Tracker. Your screenings are stored on your iPhone and nowhere else.
- All your data stays on your iPhone. Nothing is sent anywhere.
- No account, no sign-up
- Face ID lock
- Discreet notifications that only say “Reminder”
Not medical advice
Tracker does not replace advice from a healthcare professional. The time frames shown are general guidelines. For any question about your situation, talk to your doctor or a sexual health clinic.
