No account. No XtrkR server. Nothing to sign up for. XtrkR is a private sexual health tracker for gay and bi men, built by one person who wanted it for himself and could not find it. I made it because the health side of my sex life lived in my Notes app: PrEP doses, test dates, who and when. Every app that could have held it was either a general health app that did not know what 2-1-1 was, or a dating app I would never trust with it. So I built the thing I wanted. Every health tool in it is free, for everyone, forever. The paid part is the analytics on top, and it exists so the app charges the people who choose to pay instead of paying for itself with your data. EVERY HEALTH TOOL IS FREE • Every PrEP regimen: daily, on-demand 2-1-1, and both injectables, Apretude (every 2 months) and Yeztugo (every 6 months), with PrEP streaks and reminders • ART tracking • DoxyPEP doses tied to the encounter they follow, with the 72-hour window • A 28-day PEP course with follow-up test reminders • STI tests by site (throat, rectal, urethral, blood) with pending-result alerts • Vaccinations: HPV, Hep A and B, Mpox, meningococcal, with dose series • Exposure windows and PEP eligibility by HIV test type • Testing reminders that adjust to how active you are • A clinic finder, a provider summary PDF you can hand your doctor, and a shareable "I got tested" badge • Siri ("Hey Siri, I took my PrEP"), widgets, and personal goals It is the first app to combine both injectable PrEP regimens, Apretude (every 2 months) and Yeztugo (every 6 months), with site-specific STI testing, exposures, and partner history, all on-device. LOG AND PLAN • Encounters with partners, protection, mood, setting, and location. Locations are saved at city level rather than as a precise pin. • Partner profiles, a planner with calendar integration, and a pipeline for the people you intend to see again • Share a profile from more than 20 dating and social apps straight into XtrkR • Import contacts to create partners fast • Log anonymously, or with whatever label you would use in your head. Nothing has to be a real name. PRIVACY, IN PRACTICE • Your records stay on your iPhone. There is no XtrkR server, and I do not have technical access to what you store. • "Data Not Collected" across every App Store privacy category. No third-party SDKs, no analytics, no ads. • Face ID or PIN on every open, and the app covers itself when you switch away • A discreet icon and camouflaged notifications by default, so nothing on a lock screen names anyone • Optional $2.99 icon collections if you want the app to look like yours • Optional iCloud backup, AES-256 encrypted with a password only you hold • Auto-delete older records on a schedule you set. One button deletes everything. PREMIUM: THE ANALYTICS ON TOP Thirty days of everything free, no card. Then, only if you want it: • Core, $199.99 one time. Every premium feature, yours forever. It exists because I hate subscriptions too. • XtrkR+, $49.99 a year. Every premium feature plus Wrapped, your year in review, included each year. Auto-renews; cancel anytime in iOS Settings. Premium adds adherence analytics, the full insight library, the wellness score, the encounter map, photos and videos on entries, encrypted iCloud backup, and advanced stats. Pricing, explained honestly: https://xtrkrapp.com/pricing-ethics Built by one person, for the community I'm part of. It informs; it does not prescribe. Your provider always comes first.
