N=1 experiment tracker for supplement stackers
Build a cross-platform self-experimentation tracker for supplement users and biohackers with large stacks, correlating logged inputs (supplements, meds, habits) against daily outputs like energy, sleep, mood and focus, with confidence levels based on sample size. Target the gaps in existing tools: add Android support, broader health data sync beyond sleep, and multi-variable experiment design for people juggling many supplements at once, since current users are stuck with memory, notes or spreadsheets.

Weather-health citation API for niche symptom trackers
Build niche vertical apps (migraine trackers, asthma/COPD managers, outdoor sports performance apps, eldercare wellness dashboards) that plug into Vasus's environment-health citation API to surface personalized, science-backed alerts tying weather patterns to symptoms. A solo builder can wrap this API into a branded consumer app or sell it as an add-on feature to existing health and wellness apps that currently lack credible scientific grounding.

Screening tool for ADHD, autism, trauma overlap
Build a self-assessment web app that helps adults and parents untangle overlapping symptoms of ADHD, autism, and complex trauma (CPTSD) - a scored questionnaire plus educational breakdown of which traits point to which condition, with referrals to specialists, testing services, or coaching. Monetize through a detailed paid report, affiliate links to diagnostic/therapy providers, or a clinician directory.

Side-effect tracker for GLP-1 drug users
Build a lightweight companion app for GLP-1 drug users (Ozempic, Wegovy, Mounjaro) that logs side effects like hair loss, brittle nails, and muscle loss, and nudges users on protein, biotin, collagen, and vitamin intake to offset nutrient deficiencies. Target the large, vocal online community of GLP-1 users already swapping tips about these exact symptoms, and monetize through subscription or supplement affiliate links.

Non-streak pacing mechanic for habit-reduction apps
Build a paid habit-reduction app using the same growing-break mechanic (threshold that stretches 5% a day instead of a streak that resets) applied to a different vice with a bigger paying audience, such as vaping, drinking, porn, or social media. Use on-device Apple Intelligence for the reflection summaries as the privacy hook, and charge a subscription since the original Fallow app explicitly leaves money on the table by shipping free with no ads or IAP.
