Doesn't look like it can pull in historical data or nutrition pull from Apple health. then i went for 7 miles run and it only gave me lightly strained. I'll stick it out for a while to see if it can improve bc i love what it can be! **Developer response:** Hi sydboo, thank you so much for taking the time to leave a review, we really appreciate the feedback and are glad you see the potential! A quick note: Prysm should be pulling historical data and nutrition from Apple Health, so it's possible not all HealthKit permissions are enabled. You can check under Settings → Health → Data Access & Devices → Prysm and make sure everything is toggled on. That said, we'll investigate on our end regardless to make sure nothing is off. If you have any other ideas, feedback, or bugs to report, please email us at Support@MarianiGroup.app we're always seeking out active feedback so we can keep improving the app. ### 5/5 — Powerful Tool *2026-02-15* I honestly didn’t realize how much I needed this app until I started using it. The layout is clean, the features are robust, and it feels very well thought out overall. Being able to track fasting alongside my biomarker data and view correlations over time would really elevate the experience. This addition would make the app even more powerful for users focused on metabolic health. ### 5/5 — Seamless with Apple Watch *2026-01-30* I almost never write reviews, but this app really impressed me. It’s been incredibly consistent and intuitive, and the insights line up well with how I feel day to day. Using it with my Apple Watch has been seamless and genuinely helpful. ### 5/5 — This should be built into iPhone *2025-11-05* The way this app blends sleep, recovery and stress is something Apple should’ve done years ago. It almost feels like a missing default app that finally connects my body to my data! **Developer response:** Thank you for such a thoughtful review. It’s incredibly meaningful to hear that the app feels like a natural extension of your health data, that’s been our goal from day one! ### 5/5 — Great overall for my health *2025-10-28* Great insight into my health in and out of the gym ### 5/5 — Really appreciate the unique algorithms *2025-10-23* This app provides a lot more helpful insights than other health monitoring apps. I have yet to find an app that is able to provide clear health metrics with explanations on how they reach the “scores”. **Developer response:** Thank you for the thoughtful review. Our goal is to provide clear, transparent health metrics. Not just scores, but meaningful explanations behind how they’re calculated. Users can better understand and trust their data this way. We’re continually refining our algorithms and expanding insights, and feedback like yours helps guide that work. We appreciate your support. ## Frequently asked questions about Prysm ### What is Prysm?
