MiaCare: Migraine Forecast
Barometric pressure & headache
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Plan your day with a clearer view of pressure changes.
MiaCare brings pressure forecasts and headache logs together. You can use both without an Apple Watch.
◆ Check pressure changes ahead
View today's and tomorrow's pressure forecasts, charts and hours to pay attention to. Pressure-change notifications can help you plan ahead.
◆ Prepare for tomorrow
See a short summary of tomorrow's forecast and patterns in your headache records. This summary appears only when enough forecast data is available.
◆ Log and review headaches
Record symptoms, intensity, medication use, possible triggers and notes. Log several headaches on the same day and save the pressure available at the time of recording.
◆ Understand your patterns
With a compatible Apple Watch or Health data, view estimated stress, sleep, activity and trends in your records. Available information depends on your device, data and permission settings.
◆ Everyday self-care
Use breathing guides, Home Screen widgets and the Apple Watch companion app.
◆ Free and Premium
The free version includes today's and tomorrow's pressure forecasts and headache logging. Premium adds forecasts for 10 days including today, long-term trends and other features, and removes ads.
Check the purchase screen for monthly and yearly prices and free-trial eligibility. Subscriptions renew automatically. Manage or cancel them in your Apple Account subscription settings. Purchase restoration is supported.
◆ Your data
App records are stored on your device. Forecast retrieval, advertising and usage measurement use external services. See our privacy policy for details.
Forecasts require location access and an internet connection. Notifications require permission. Pressure and condition information is intended as a reference for everyday self-care. It does not guarantee headache prediction or improvement and is not a medical device for diagnosis or treatment.

1.10.2 2d ago
Our white office cat Ramune has had a bent front paw since we rescued him. Supplements seem to make him much more comfortable, but then he gets carried away, climbs on top of the air conditioner, and can't get back down. Please give us a break, Ramune.
Here's what's new in v1.10.1.
• Prepare for tomorrow
The forecast screen now includes a short summary of tomorrow's pressure and patterns in your headache records.
• Easier headache logging
You can now log multiple headaches on the same day. This month's records have a more compact layout, with clearer guidance when a recording action runs into a problem.
• Improved pressure alerts and displays
Refined alert decisions to match the periods when pressure falls. Also improved Live Activity results and guidance when location searches fail.
• Updated colors and Premium guidance
Refreshed the app with soft pastel colors. After purchasing Premium, it's easier to reach the features you want to use.
Thank you for using MiaCare.
1.10.1 Oct 5
Our office cat Ramune turned 10!
For his birthday, we gave him a stuffed toy, one of his favorite things. He's been enthusiastically kicking it around as he plays. We're glad he likes it.
Now, here's what's new in v1.9.3.
• More reliable weather and pressure updates
Improved issues that prevented widgets and Live Activities from refreshing, and fixed mismatches between the location name and weather after moving to a new location.
• An easier-to-use Apple Watch app
Refined the screen layout and added support for the theme color you choose on your iPhone. Weather now refreshes automatically when needed as you open or use the Watch app. Update status and guidance for connection problems are also clearer.
• Improved layouts
Adjusted layouts for landscape orientation and larger text sizes on iPhone.
Thank you for using MiaCare.
1.9.3 Sep 25
Our white cat Ramune's tenth birthday is getting closer.
He's still very affectionate these days. He just bit me.
Now, on to what's new in v1.9.2.
• A clearer Dynamic Island
The compact view shows the alert icon, weather, temperature, and humidity, with pressure on the right. Touch and hold to see the pressure alert timeline and its expected end time.
• Improved landscape layouts
Pressure, stress, activity, and insights screens now have clearer spacing and layouts for different screen sizes and orientations.
• Easier-to-use care guides
Breathing and muscle relaxation guides resume where you paused and automatically pause when you leave the app.
• More reliable displays
Fixed duplicate Live Activities and displays remaining after an activity ended. Improved pressure forecast notification timing and date labels.
Thank you for using MiaCare.
1.9.2 Sep 16
This month our white cat Ramune turns ten. The tiny kitten we rescued on a stormy day has spent all these years by our side.
Version 1.9.1 improves pressure information and everyday logging.
• Live Activities on Apple Watch
A dedicated card shows the alert level, current pressure, 3-hour change, estimated end of the caution period, and last update. Tap it to open the Watch pressure screen. Requires iOS 18 and watchOS 11 or later.
Enable Live Activities in Settings to see them during caution periods. The iPhone Lock Screen also distinguishes forecast times from the last update. Live Activities are off by default.
• Clearer metric details
We have simplified the layout and explanations for HRV, heart rate, sleep, breathing, sound, daylight, steps, walking distance, stairs, walking heart rate, and other metrics.
• Easier access to long-term trends and Premium
Long-term trends have a clearer place in history and preview part of your saved records before subscribing. If there are no records, we show that state. Your personal Insights can show how headache-recorded days overlap with caution days before subscribing. If data is insufficient, we explain what is needed.
Premium explanations now match the feature you want to use. Monthly and yearly prices and free-trial terms are easier to compare. We have also improved product reloading and purchase restoration. Existing free features remain available.
• Better widget and Siri logging
Feedback after tapping the headache button is clearer. Repeated taps for the same episode are grouped, while later episodes can be recorded separately. Settings includes a widget setup guide.
Ask Siri for tomorrow's pressure-related risk guidance. After logging a headache, an optional short breathing exercise may be suggested.
• Protecting your records
Fixed an issue where logging with Siri could cause menstrual and self-care records to be lost. Records lost before this update cannot be recovered.
Thank you for using MiaCare.
1.9.1 Sep 9
This month our white cat Ramune turns ten. He started out as a stray — we took him in on a day of thunderstorms, a skinny little kitten. We brought him home meaning to make him the happiest cat in the world, so here's to many more healthy years.
This time we looked at the headaches that may not be about pressure at all.
■ Triggers beyond pressure
"Screen / desk work" and "Alcohol / caffeine" are now available as triggers on your records, and the Insight tab has a new "Your trigger patterns" section. It shows how often each trigger overlapped with a drop in pressure, so you can tell apart the ones that come with the weather and the ones that don't.
If step data is available, days when you moved less than usual are now reflected in your outlook — for when a long day at the desk lines up with falling pressure. If step data isn't available, nothing changes.
■ Share today's alert times
You can now share today's alert times as an image — handy for telling family or friends to take it easy tomorrow. The image shows only pressure and time of day; none of your records are included.
■ Records made from notifications and widgets
Until now, recording from a notification or widget while the app was closed often left no pressure reading attached. We now fill in the change from the weather forecast, so those records count toward your own patterns too.
■ Cycle predictions from day one
Cycle setup now has a "cycle before last" entry. With three cycles in place, your next prediction is ready the same day you set it up. If you don't track your cycle, nothing about your display or outlook changes.
■ A clearer alert-times widget
When the colored band crosses midnight, it now shows whether those hours are today or tomorrow.
Thank you for using MiaCare. We'd love to hear your thoughts.
1.9.0 Sep 1
Our white cat Ramune loves play bites. Lately he misjudges his strength and it honestly hurts.
Now you can see when it starts and when it eases — without opening the app.
■ Today's risk hours (widget)
A new widget shows which hours of the day need care, as colored bands, with a marker for where you are now. Put it on your Home Screen or Lock Screen and check at a glance.
■ When it eases
Until now we could only tell you that rough weather was coming. We now show roughly when the pressure looks set to recover, so you have something to plan around.
■ Alongside your cycle
If you track your cycle, we now factor it in together with pressure changes. When a big drop lines up with your cycle, the outlook accounts for it. If you don't track it, nothing about your display or outlook changes.
■ If you don't have an Apple Watch
Stress needs an Apple Watch, but pressure and headache risk work for everyone. The card on the Home tab now takes you straight to the pressure screen.
Thank you for using MiaCare. We'd love to hear your thoughts.

What's New in v1.7.2
New
• Quiet Hours summary: "Caution"-level alerts during the night (10 PM–7 AM) can now be bundled and delivered together at 7 AM the next morning. Urgent alerts are still delivered right away. (Off by default; you can turn it on in Settings.)
• If notifications appear to be turned off, we now show a banner to help you re-enable them.
Improvements

Thank you for using MiaCare.
1.7.3 Jul 22
Earlier, our very own Gumi-chan attempted to jump onto the bookshelf, missed, and sent a spectacular pile of books flying.
So, this release comes to you from the middle of a small literary disaster.
Now, about this fix: we’re truly sorry.
We fixed an issue where the Watch app could consume more battery than expected.
1.7.1 Jul 7
This update helps you see more — not just headaches, but the bigger picture of your stress.
■ Log more than headaches
You can now record other symptoms too — fatigue, dizziness, sleepiness, stiff shoulders and more (choose several at once). The barometric pressure and your autonomic state (tiredness) at that moment are saved automatically, so “Symptom trends” in Insight shows whether each symptom tends to line up more with pressure drops or with tiredness.
■ Long-Term Stress Trend (Premium)
A new card lets you look back over 3 months to a full year — not just today and this week. From your own data it quietly surfaces findings like turning points (when things changed), rhythm (which day and time tends to run high), and factors (such as overlaps with shorter-sleep days). You can also see seasonal shifts and year-over-year comparisons.
■ A one-tap morning check-in after pressure alerts
On the morning after a big pressure change, a gentle notification asks “Did you get a headache yesterday?” Tap “Yes” to log it without even opening the app — and the more you log, the clearer your pressure-and-headache pattern becomes (only when Headache Alerts are on; you can turn it off in Settings).
■ Other
・Added a caution icon for tropical storms in the weather forecast.
・Refined the long-term trend display and fixed several issues.
Thank you for using MiaCare. We’d love to hear your feedback and requests.
1.7.0 Jul 5
Version 1.6.3
Thank you for using Mia Care.
The other day, our beautiful black cat Gumi celebrated her 9th birthday.
She loves cardboard boxes and is very cute as a sheltered princess, literally in a box.
This time, we carefully reviewed the accuracy of pressure alerts and the connection with Apple Watch and widgets.
New features and improvements
* Earlier awareness of pressure warnings
Mia Care now notifies you more reliably of caution and warning levels, even when air pressure drops gradually. We also aligned the color bands in the graph with the warning badge shown at the top.
* Fixed display differences between Apple Watch and the app
We improved consistency so that location, air pressure, and stress values do not differ between iPhone and Apple Watch. The latest status now updates more smoothly when you raise your wrist or when the app is in the background.
* Unified warning levels across widgets, Apple Watch, and the app
The same warning level is now shown wherever you check it.
* Adjusted sleep evaluation to feel more natural
* Made the air pressure graph lighter and smoother
Notification frequency remains the same as before.
We will only send notifications when needed, so you can continue using Mia Care with peace of mind.
1.6.3 Jun 22
Rainy season headaches can be tough.
This update brings new features designed to gently support you while traveling and in everyday family life.

Register your destination to check local air pressure trends and headache signs in advance. Helpful for preparing your condition before a trip.
■ Manage family headaches by person (Premium)
You can now record headaches for your children or family members, and switch insights by person. This makes it easier to see whose headache records you are viewing.
*Alerts, widgets, and Apple Watch continue to be based on your own current location.
■ Save reflection images to Photos
Headache diary-style “reflection images” can now be saved directly to your Photos app, in addition to being shared.
■ Select a person when exporting
If you have family members registered, you can choose whose data to export for CSV files and reflection images.
Improvements
・We reviewed and improved the accuracy of displays related to air pressure forecasts and records.
・We fixed minor issues and improved overall stability.
We’ll continue helping you live more comfortably with headaches.
1.6.2 Jun 12
MiaCare has moved onto your watch face.
MiaCare now supports Apple Watch face complications.
You can add “Pressure caution,” “Stress,” and “Activity” to your watch face. You can also see when pressure-related caution begins, shown as “Caution from 3 PM.”
How to set it up: touch and hold the watch face → Edit → choose “MiaCare” in a complication slot
You can now customize your tabs.
Hide the tabs you do not use from Settings.
The “Pressure correlation” insight has been improved.
It now appears sooner and more accurately.
Other small improvements and bug fixes are included.
Thank you for using MiaCare.

A quiet moment with a cat curled up in your lap. We’ve made it even easier to record changes in how you’re feeling during everyday life.
