Everything you need to write about XtrkR: screenshots, founder bio, fact sheet, and the story behind why a sexual health tracker for gay and bi men needed to exist.

01. The pitch

XtrkR is a private sexual health tracker for gay and bisexual men. It is the first app to combine both injectable PrEP regimens (Apretude every 2 months, Yeztugo every 6 months) with site-specific STI testing, exposures, and partner history. It also tracks daily PrEP, DoxyPEP, vaccinations, and encounter logs. Everything is primarily stored on the user's iPhone (encrypted iCloud backup is opt-in). No XtrkR servers, no accounts, no third-party analytics. Every health tool is free: all four PrEP regimens (daily, on-demand 2-1-1, Apretude, Yeztugo), STI testing, DoxyPEP, PEP, and vaccinations, with no trial clock. Optional premium adds analytics and insights on top: $199.99 one-time (Core) or $49.99/year (XtrkR+).

In plain terms: the app is free to use. Premium is optional analytics, not a wall in front of anyone's health data.

03. Why it exists

Most general-purpose health trackers were not built with gay and bi men in mind. PrEP doesn't fit cleanly into period trackers. Generic symptom diaries don't ask about exposure sites. And many of the apps that do serve queer health needs route data to a server, one that could be subpoenaed or breached.

XtrkR was built around a simple constraint: data stays on the user's iPhone, not on servers I operate. As the developer, I do not have technical access to the health records users store in the app. It's an architectural posture, not a policy promise.

It also exists because of a gap the guidelines name directly. CDC's STI Treatment Guidelines put it plainly: "Approximately 70% of gonococcal and chlamydial infections might be missed if urogenital-only testing is performed among MSM … because most pharyngeal and rectal infections are asymptomatic" (CDC, 2021). One of the studies cited for that line found that "more than 70% of extragenital GC infections and 85% of extragenital CT infections … would not have been detected with urethral screening alone" (Patton et al., Clinical Infectious Diseases, 2014; 21,994 MSM at 42 STD clinics). XtrkR records which sites were tested on which date.

04. What's tracked

• Injectable PrEP: Apretude (cabotegravir, every 2 months) and Yeztugo (lenacapavir, every 6 months), with injection history and injection reminders
• Daily PrEP, 2-1-1, and DoxyPEP with adherence streaks and condomless-encounter reminders
• STI tests by site (rectal, pharyngeal, urethral, blood) with due-date logic
• Vaccinations (HPV, Hep A, Hep B, Mpox, Meningococcal) with multi-dose tracking
• Encounters with partners, mood, location, and configurable activity categories
• On-device insights (streaks, patterns, nudges), computed with no AI cloud calls; the first three are free, the full set is premium

06. Founder bio

Ed is a solo developer working through De Nihil LLC. A queer Latino man, he was a patient at a queer specialty clinic in San Francisco for years before he was a founder. That clinic meant multi-site STI screening, PrEP-aware testing rhythms, and the kind of queer-aware care a generic PCP couldn't model for him.

The clinical care itself (visits, shots, medicine) is available from many providers; what changed when he moved was the queer-aware framing around it. He tried other apps first; none captured what he needed. XtrkR keeps his own continuity intact across whatever clinician he sees next. It's meant to complement queer-aware clinical care, not replace it.

Not every app handles privacy the same way. He built XtrkR solo because he wanted user data to stay user data, and to make that structurally hard to walk back later. No investors to push for monetization, no team to grant data access, no XtrkR servers to subpoena or breach. The full story is at xtrkrapp.com/about.

07. Talking points

• Built natively around both injectable PrEP regimens with site-specific STI testing on-device. Apretude (cabotegravir, every 2 months) and Yeztugo (lenacapavir, every 6 months), tracked alongside exposures, partner history, and daily regimens. Everything is primarily stored on the user's iPhone (encrypted iCloud backup is opt-in).
• Privacy by architecture, not promise. Data is stored on the user's iPhone, not on servers I operate. There's no XtrkR server holding records to leak.
• Built for gay and bi men specifically. Four-site STI testing (rectal, pharyngeal, urethral, blood), PrEP adherence, mpox/HPV vaccination workflow.
• Pride Wrapped: a private letter-to-future-self ritual for queer time-capsule keeping. Five short prompts each June, sealed for twelve months, opens the following June 1 alongside an eight-card watercolor deck of queer history for the user's cohort year. Pairs with Year-End Wrapped (the 2026 edition drops in January 2027). Pride Wrapped 2026 is free for every user, capsule and deck, with no paywall; the 2026 writing window ran June 1 to July 1, and Class of 2026 capsules open on June 1, 2027. Year-End Wrapped unlocks with the $9.99 Wrapped Pass. Full detail at xtrkrapp.com/pride.
• Makes site-specific testing visible. CDC: about 70% of gonococcal and chlamydial infections among MSM might be missed by urogenital-only testing, because most pharyngeal and rectal infections are asymptomatic (CDC STI Treatment Guidelines, 2021). XtrkR records which sites were tested on which date.
• Zero third-party SDKs in the app. No in-app analytics, no automated crash reporting, no Firebase. Users can optionally share diagnostics from Settings. Verifiable with a network monitor: the only servers it contacts are Apple's (StoreKit for purchases, MapKit for maps, place search, and geocoding, and iCloud if backup is on).
• Encrypted backups are opt-in only. AES-256-GCM with a user-derived key.
• The health tools stay free for every user. Medication tracking (all PrEP regimens, PEP, DoxyPEP, ART), STI testing, vaccinations, symptoms, exposure windows, and the doctor visit PDF are free in the free tier. Not on a trial, not until a usage threshold. Premium adds the analytics layer on top. Full breakdown at xtrkrapp.com/pricing-ethics.
• Solo founder, sustainable model. Dual-path pricing: $199.99 one-time Core (yours for the lifetime of the app) or $49.99/yr XtrkR+ (adds Wrapped every year). Both paths always available; the subscription is anchored by a published guardrail page (easy cancellation, pro-rata refunds, grandfathered pricing). Free tier for core logging, no investors, no growth-at-all-costs pressure, no ads in the app, no data sales.
