Your steroid taper, day by day.
Downdose keeps your prednisolone taper straight: today's dose and tablets, a gentle reminder, a 20-second morning check-in, and a clear picture to show your doctor.

How it works
Enter the plan your doctor gave you
Medicine, the tablets you have at home, today's dose and the steps ahead. Downdose shows the plan exactly as you entered it — it never suggests doses.


Every morning: one glance, one tap
Today's dose in milligrams and in tablets — “one 5 mg + two 1 mg” — with a reminder at the time you choose. Tap “I took it” and you're done.


A 20-second check-in
How stiff are you this morning? How long until you loosened up? Any pain? Four quick taps, no typing.


See how you're doing — and show your doctor
Your dose and your morning stiffness on one chart, with a plain-language summary: “Since you moved to 7 mg, mornings have been a bit stiffer.”


Built for months on steroids, not days
Gentle reminders
A morning reminder, a heads-up the evening before your dose goes down, and a nudge if today isn't marked. The dose itself stays off the lock screen unless you want it there.

Sick-day rule & steroid card
Keep the rule your doctor gave you for days you're unwell one tap away, log a sick day, and show a steroid emergency card — full screen if you need it.

Your doctor changed the plan?
Update it in a minute. The old plan stays in your history, so the chart still makes sense.

Tablets, not just milligrams
Tell Downdose which strengths you have at home and it shows what to take each day.

Private by design
No account, no server. Everything stays on your phone. Backups are locked with a key only you hold and go to your own iCloud Drive or Google Drive.

Easy to read
Large text, high contrast, big buttons — and it follows your phone's text size. English, Deutsch, Italiano.

Who it's for
People taking prednisolone or prednisone for months — polymyalgia rheumatica (PMR), giant cell arteritis, lupus, asthma, inflammatory bowel disease and others — and the people who look after them: you can set Downdose up for someone else.
Your data stays on your phone
Everything you enter stays on this phone. Downdose has no account and no server. The only data that leaves your phone is anonymous usage data (which screens are used — never doses or symptoms), and you can turn that off in the app.
Questions
Does Downdose tell me what dose to take?
No. It only shows the plan you entered, exactly as your doctor wrote it. If anything is unclear, ask your doctor or pharmacist.
Which medicines does it support?
Prednisolone, prednisone, methylprednisolone, hydrocortisone — or any other steroid you name — in any tablet strengths, once or twice a day, every day, alternate days or weekdays only.
Does it work without internet?
Yes, completely. There is nothing to sign up for.
What does it cost?
Downdose is free.
Which phones?
iPhone with iOS 16 or later, and Android phones with Android 8.0 or later.
What if I get a new phone?
Make a backup (More › Back up & restore), keep the recovery key on paper, and restore it on the new phone.
