Read full descriptionHide full description
Your genetics may influence how medications are processed by your body and DecodeRx helps make that science easier to understand. Built on published CPIC (Clinical Pharmacogenetics Implementation Consortium) guidelines, DecodeRx is an educational reference that maps 39 commonly prescribed medications to the pharmacogenes involved in their metabolism. Whether you've already received pharmacogenomic test results or you're new to the topic, DecodeRx presents evidence-based information in a clear, clinical interface — entirely offline, with no account, no upload, and no data collection. PERSONAL PHENOTYPE MODE If you have a pharmacogenomic test result, you can record your metabolizer status (Poor, Intermediate, Normal, Rapid, or Ultrarapid) for each gene the app covers. The medication library then highlights what's most relevant to your phenotypes and the detail screen pins the matching CPIC guidance to the top, so you can see in one tap what published guidelines say about your phenotype and a given medication. Your phenotypes stay on your device. They are never uploaded, shared, or collected. REFERENCE CARD DecodeRx can generate a clean PDF reference card summarizing your entered phenotypes and the medications they affect, ready to print or share with a healthcare provider via the iOS share sheet. Generated entirely on-device. EVIDENCE-BASED FROM THE GROUND UP DecodeRx draws from CPIC Level A and Level B gene-drug interaction guidelines, the gold standard in pharmacogenomic clinical practice. Every effect summary is grounded in published clinical literature, paraphrased for clarity. 39 MEDICATIONS · 9 PHARMACOGENES · 7 CATEGORIES Browse medications across Psychiatric, Cardiovascular, Pain, Gastrointestinal, Oncology, Immunosuppressants, and Other categories. For each medication, DecodeRx surfaces the relevant pharmacogenes — including CYP2D6, CYP2C19, CYP2C9, VKORC1, SLCO1B1, DPYD, TPMT, NUDT15, and CYP3A5 — and explains what each metabolizer status (Poor, Intermediate, Normal, Rapid, Ultrarapid) may mean for that drug. SEARCH BY GENERIC OR BRAND NAME Find what you're looking for instantly — clopidogrel or Plavix, sertraline or Zoloft, tamoxifen or warfarin. PRIVATE BY DESIGN DecodeRx makes no network requests of any kind. There are no analytics, no third-party SDKs, no advertising identifiers, and no accounts. All content is bundled with the app at install time. Phenotype data and the optional name you enter for your reference card stay only on your device, and you can delete them at any time. COMPLETELY FREE No in-app purchases. No subscriptions. No ads. No upsells. Just a free educational reference tool. DESIGNED FOR CLARITY DecodeRx is an educational reference. It does not provide medical advice, diagnosis, or treatment recommendations. Always discuss medication decisions with a qualified healthcare professional.

Most guys have no idea whether their daily habits are helping or hurting testosterone. T-Score helps you track the daily behaviors most associated with healthy testosterone. Every day, it grades the six habits that matter most against research-based targets, so you can see where you're on track and where you're slipping. WHAT YOU TRACK - Sleep: the single highest-impact variable - Training: resistance, HIIT, cardio, or other - Nutrition: whole foods, protein, real meals - Sunlight: morning circadian anchor - Cold exposure: deliberate stress exposure - Supplement stack: your protocol, your way APPLE HEALTH INTEGRATION Connect once and T-Score can auto-fill your sleep hours and workouts every day. It categorizes workouts automatically, such as lift sessions as WEIGHTS, runs as CARDIO, and classes as HIIT, and learns your preferences over time. DAILY T-SCORE Get a 0 to 100 score for how well you hit today's targets. See exactly which habits cost you points and which ones maxed out. Same inputs, same score, so improvement is measurable. BLOODWORK TRACKING Log your lab results, including total T, free T, and SHBG, and view them over time. 365-DAY DISCIPLINE GRID See every day of the past year at a glance. No cherry-picking, no excuses, just your actual track record. HABIT CORRELATION ANALYSIS After 5 or more check-ins, T-Score shows you which habits correlate with your highest scores so you know where to double down. BUILT-IN SUPPLEMENT PROTOCOLS Dose, timing, mechanism, and peer-reviewed citations for 9 T-supporting supplements: vitamin D3, zinc, magnesium, ashwagandha, tongkat ali, creatine, omega-3, boron, and DHEA. PRIVACY FIRST All check-ins and bloodwork stay on your device. No accounts, no cloud, and no data selling. You own your record.

Verdict
The clearest difference is in-app purchases: DecodeRX at none against T's 2. DecodeRX also leads on ads (none vs shown). T's advantage is update cadence (daily vs monthly) and iOS requirement (15.1 vs 18.0). On price and device support there is nothing between them.
