Highlights

  • Log subluxations, pain, fatigue, and energy pacing day to day
  • Apple Watch & Wear OS companion for quick logging on the go
  • Local-first & private — no account needed to start
  • Clinician-ready PDF/CSV reports for your next visit

HSDiary is for the everyday reality of living with Hypermobility Spectrum Disorder — the subluxations, the fatigue, the push-and-crash cycles, and the appointments where it’s hard to convey how variable each day really is.

It keeps logging quick and low-effort: note what happened, how your energy held up, any pain or subluxations, and let the app surface patterns over time. When you see your care team, export a clean summary so the conversation can focus on what matters rather than trying to recall the last few weeks from memory.

Built to respect you: your entries stay on your device by default and Helperly never sells your data. The free version is supported by ads through Google AdMob (which applies its own tracking); upgrading removes them and unlocks more. Either way, the app is for logging and insight — never a diagnosis or medical advice.

Features

  • Fast daily logging

    Capture subluxations, pain levels, fatigue, triggers, and medications in seconds — built around the unpredictable day-to-day of HSD.

  • See your patterns

    Trends, charts, and plain-language insights help you understand what affects your energy and symptoms, without guesswork.

  • Pacing & subluxations

    Record subluxations, pain, and fatigue, and track energy pacing so you can plan around your limits.

  • Private by design

    Your health data stays on your device by default and Helperly never sells it. The free version is ad-supported through Google AdMob (which does its own ad tracking); upgrade to go ad-free. Logging and insight only — never a diagnosis or medical advice.

Your privacy

Your health data stays on your device by default — local-first, with no account required to begin. Helperly never sells your data. HSDiary helps you log and understand patterns; it does not provide a diagnosis or medical advice. The free version is ad-supported through Google AdMob, which applies its own ad tracking; upgrade to remove ads.
