Welleo

Welleo is the first preventive health ecosystem that connects biomarker testing with a personalised supplementation protocol, guiding you day by day until your next control test. How it works When you sign up, Welleo asks about your goals, habits, and how you feel. Based on your answers, it builds your personal wellness wheel and identifies which biomarkers make sense to measure. The test takes 15 minutes at a partner pharmacy: a small capillary blood sample analysed with the Welleo reader, powered by immunofluorescence technology. Results arrive directly in your app: your value, the ideal range, and a visual bar so you understand them at a glance. Welleo then generates your supplementation protocol: what to take, at what dose, and for how many cycles. When the time comes, it reminds you to repeat the test and confirm whether the protocol worked. What you can measure Vitamin D · Ferritin · TSH · Cortisol · CRP · βhCG · Estradiol and more biomarkers based on your profile and goals. For your daily routine — Log your daily supplement doses directly from the app — Track each cycle's progress and your next scheduled test date — Add existing test results for a more complete picture of your health — Find your nearest Welleo pharmacy on the map For pharmacy professionals The same app includes a verified professional interface: — Appointment scheduler and QR-based test registration — Patient panel with per-biomarker status and markers-to-review alerts — Detailed patient profiles with history, progress, and wellness goals — Clinical academy with guides by health objective: metabolism, immune system, sport, sleep, hormones and fertility — Send personalised recommendations directly to patients The full loop Test → wellness wheel → protocol → daily supplementation → control test → adjustment. Every measurement validates the previous protocol. We don't assume what you need, we measure it. Available at selected pharmacies in Spain.

Verdict
The clearest difference is ads: Welleo at none against Simon iO's shown. Welleo also leads on update cadence (weekly vs every 3 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
