An EDS and HSD diary that connects the pain to what came before.
Bucket is an iPhone app made for the Ehlers-Danlos syndromes and hypermobility spectrum disorders (EDS/HSD). Log joint pain and partial dislocations alongside shifts, lifting, exercise and weather. Bucket shows how it adds up, what tends to come before your bad days, and writes a plain summary to take to rheumatology or physio.
What people with EDS/HSD often log.
What they met and did
Shifts, lifting and long days on your feet
Exercise, physio, yoga and hydrotherapy
Weather and pressure changes
Poor sleep, your period, being unwell
Pain relief and other medicines
How they felt
Joint pain
Partial dislocations
Tiredness
Dizziness, if POTS travels with it
Reactions, if MCAS does
Examples of what people often track — not a list of causes or symptoms to look for. You choose what to log, and Bucket learns your own pattern.
Asked in EDS/HSD’s own words.
When you set Bucket up, you choose every condition you have or think you might — diagnosed, suspected or still exploring. Each brings a question of its own, in words people with it use. For EDS/HSD it’s “Joints” — steady, usual or very loose. Bucket doesn’t ask it every day, only now and then, after a heavy spell.
Your entries fill a bucket that drains over the following days, so you can see the load building. Once there’s enough in your diary, Bucket shows what tends to come before your bad days — the same day or up to about three and a half days earlier.

What Bucket does for EDS/HSD.
-
Every type, in your own words
Bucket covers hEDS, the other Ehlers-Danlos types and HSD, and you can write in which one is yours.
-
Effort counted, physio included
Shifts, lifting and workouts count as effort, body and mind separately. Yoga, Pilates, hydrotherapy and physio count as exercise does, unless a Watch workout already covers that time.
-
Weather, added for you
Pressure, heat and air for your rough area are added each day, so you can see whether a change in the weather tends to come before your worse days.
-
Ready for rheumatology
Keep each appointment with your questions ready, and take a plain summary of what you’ve logged — counted on your phone from your own diary — to send or print.
-
One diary for everything that travels with it
Many people with EDS/HSD also have POTS or MCAS. Choose every condition you have or think you might; one diary covers them all, with a question of its own for each.
Meet Rhys.
Rhys was newly diagnosed with EDS. His records are ready for rheumatology.
Rhys is one of three made-up sample people built into the app, so you can try it before you’ve logged anything. A sample — not a testimonial.
Questions about Bucket and EDS/HSD
Is there an app for tracking EDS or hypermobility symptoms?
Yes — Bucket is an iPhone app made for EDS and hypermobility spectrum disorders (HSD), among other conditions. You log joint pain and partial dislocations alongside work shifts, lifting, exercise and weather, and it shows what tends to come before them. For appointments, it writes a plain summary of what you’ve logged to take to rheumatology or physiotherapy.
Does Bucket work for HSD as well as hEDS?
Yes. Bucket covers all the Ehlers-Danlos syndromes and hypermobility spectrum disorders (HSD), and you can write in which type is yours.
Can I track partial dislocations in Bucket?
Yes. Log a partial dislocation or joint pain with a 0–10 slider, and a question of its own about how your joints feel — steady, usual or very loose. Bucket then looks for what tends to come before them, including shifts, lifting and weather a day or two earlier.
I have more than one condition — does Bucket work for that?
Yes. Bucket lets you choose every condition you have, or think you might, and one diary covers them all — many people with MCAS, POTS, EDS/HSD or migraine have more than one.
Can Bucket help me get ready for rheumatology or physio?
Yes — Bucket keeps each appointment with your questions ready and writes a plain summary of what you’ve logged, to send or print for the clinician you’re seeing.
Is Bucket an EDS or hypermobility test?
No. Bucket is a diary: it never diagnoses or scores hypermobility. It shows what tends to follow what in your own records, to take to the clinicians who know you.
Who wrote this.
Bucket is made by Chris, who has a connective tissue disorder and hypermobility, gets migraines, and is working towards an MCAS diagnosis through the NHS — and built Bucket to find the delayed reactions that were impossible to spot alone. Read Chris’s note.
This page describes what Bucket does. It doesn’t explain EDS/HSD, and it isn’t medical advice. To read about EDS/HSD itself, see the NHS page.
