Ovyso turns the steps, sleep, heart rate and vitals already sitting in Apple Health into Home Screen and Lock Screen widgets worth looking at twice. Most health widgets are an afterthought — a stock ring in one flat color. Ovyso is warm and Apple-native, tiles and hero ring glowing with liquid light, every metric in its own semantic color: pick a layout, pick your metrics, pick a finish, and it lives on your Home Screen exactly as designed, staying current on its own. SIX WIDGET LAYOUTS • Metric — one hero number with its goal • Dashboard — a full grid, mirrors your day at a glance • Rings — up to three goals as concentric rings • Trend — seven days of bars next to today • Lock Screen — circular, rectangular or inline • Circle — your circle's current event and latest result SEVEN FINISHES Aurora, Graphite and Paper are free; Coral, Ocean, Forest and Solar unlock with Ovyso Pro — seven colorful, Apple-native grounds, all built on the same system that colors the data itself: steps and activity in orange, heart in red, sleep in indigo, vitals in blue, body in teal, everywhere they appear. Numbers render in Onest, a rounded numeral face built for glancing — a serif option is in the Studio too. THE STUDIO Build your own designs: choose a layout, choose which metrics it shows, choose a finish and a typography style, preview it across every size before you add it — then add it from the Home Screen widget gallery like any other widget. CIRCLES Walk with friends in events of five kinds: a Race for the most steps or distance; Target Days, won by the most days on target; a Team Goal, one big number together; a Team Streak, everyone on target every day; or a Journey along a real route like the Camino de Santiago — a progress map, an illustrated postcard at every stop — or your own route between two places. Most kinds can repeat weekly or monthly. Results come with a podium or the team's outcome, awards, and laurels that lift your rank; the latest winner holds the circle's crown, and a season of contests crowns a champion. Rank and season finishes are earned, never sold. Share a result as a poster. Invite anyone by link or six-character code. Joining is free; hosting a circle is part of Ovyso Pro. Circles needs an account: sign in with Apple or with an email address. Add friends by link, QR code or username — always free. PROFILE AND TRENDS Trends sets this week against last and charts twelve weeks. Your profile holds your rank, awards, journey stamps and records — best day, best week, longest streak — each record a shareable card in your chosen finish. No made-up scores, just what actually happened. WORKS WITH WHATEVER WRITES TO APPLE HEALTH Ovyso reads Apple Health directly, so it works with an Apple Watch, Garmin, Oura, Withings, or your iPhone on its own — including the data your Fitbit syncs to Apple Health through the Google Health app's Apple Health connection. No separate account or sync to configure inside Ovyso itself. ASK SIRI "Hey Siri, what are my steps in Ovyso?" — check a metric without opening the app. PRIVACY, PLAINLY Everything Ovyso reads from Apple Health stays on your iPhone, except the daily steps and distance you share in Circles and with the friends you accept — Circles also sees the goals you set and your name, and the friends you accept also see your username. Ovyso has no analytics, no ads and no tracking of any kind. Delete your account in Settings at any time; your totals, goals, friends and results go with it. Full detail at the privacy policy link on this page. OVYSO PRO The core app is free: two saved designs, three finishes, every widget layout, share cards in any finish, and joining as many circles as you're invited to. Ovyso Pro removes the design limit, unlocks all seven finishes, and lets you host circles of your own — one payment, no subscription. Ovyso will never show Readiness, Cardio Load, or a Sleep Score — Apple Health has no such data, and Ovyso won't invent it.

Verdict
The clearest difference is in-app purchases: PDCheck AR at none against Ovyso's 1. PDCheck AR also leads on iOS requirement (13.0 vs 18.0). Ovyso's advantage is update cadence (every 2 days vs every 3 months). On price, ads and device support there is nothing between them.
