Taper AI Is Live on the App Store: The First Mother Nature AI Product
Taper AI is now live on the App Store — the first product in the Mother Nature AI family. It's the AI medication tracking app for iPhone we wanted to exist when one of our engineers needed to taper a medication and discovered Apple Health doesn't actually let you export your data. Here's what we shipped, why it matters, and what's coming next.
Today we shipped Taper AI, the first product in the Mother Nature AI family. It is now live on the App Store: Taper AI on the App Store.
Taper AI is an AI-powered medication tracking app for iPhone. It tracks unlimited medications, builds personalized schedules, logs side effects and mood, supports gradual medication tapering, and — the part we cared about most when we started — exports a clean PDF or CSV you can hand to your doctor. Everything runs on your device.
This post is the long version of why we built it, what it does, where it fits in the broader Mother Nature AI mission, and what is coming next.
Why we built it
The Mother Nature AI thesis is that everyone should have access to reliable health information and intelligent tools that actually help them take better care of themselves. We have been building the AI chat side of that thesis for a while — that work continues — and we kept hearing one specific category of feedback from users:
"I'm trying to keep track of my medications and I cannot find a single app that doesn't either spy on me, charge me $9 a month, or fail to do the one thing I actually need — let me hand the data to my doctor."
When one of our engineers needed to taper off a medication under their physician's guidance, that abstract feedback became a concrete problem. They needed to track every dose, log how they were feeling, watch for side effects, and bring data to follow-up appointments. The job sounds simple. It was not.
The Apple Health gap that started everything
The natural first stop was Apple Health. iPhone has a built-in Medications feature that handles dose logging and basic reminders. Useful for a one-medication regimen, fine for two. But the moment you need to actually export your medication history as a PDF or CSV to share with a physician, you hit a wall.
There is no clean medication-data export from Apple Health. You can dump the entire Health database as a giant XML archive, intended for developers, but you cannot pull out a one-page medication summary. If you search Reddit for "export medications from Apple Health," you will find thread after thread of patients asking the same question and getting the same answer from each other: you cannot, at least not in any way that is useful for an appointment.
So our engineer tried third-party apps. Privacy-poor (data on remote servers), feature-thin (no mood or symptom tracking, no tapering support), or paywalled ($9 a month to be reminded about a pill). They eventually fell back to scattered notes in a text app, manually logging doses for months.
That frustration is the entire reason Taper AI exists.
What Taper AI does
The shipped product is a focused, full-feature medication tracking app:
- Unlimited medication tracking. Add as many medications as you take, each with its own dose, schedule, and notes. No medication-count paywall.
- AI-generated schedules. Enter what you take, and Taper AI proposes a schedule based on dose timing, refill cadence, and food-or-empty-stomach guidance. You can customize anything.
- Smart reminders and refill alerts. Customizable dose times, missed-dose handling, and refill warnings that fire days before you actually run out.
- Side-effect and mood logging. Quick daily entries that the AI then correlates with your dose history.
- Medication tapering support. Build a gradual reduction plan for medications that need careful step-down (antidepressants, benzodiazepines, opioids, beta-blockers, corticosteroids, etc.), and adjust the pace as you go.
- Doctor-ready PDF and CSV export. One tap generates a clean report: every medication, full dose history with adherence rate, refill schedule, side-effect log, mood chart, and an AI insights summary. Email it, print it, AirDrop it to your physician.
- 100% on-device storage. Apple SwiftData. No cloud, no sync, no server-side database. Even we cannot see what is in your account.
The AI insights piece (why "Taper AI" is the AI part)
Anyone can build a pill reminder. The reason we put the AI work in is what happens once you have a few weeks of logged data.
A few examples from our internal testing and the early users we onboarded:
- "Your mood ratings have dropped about 2 points on average since you reduced your dose three weeks ago. That tracks with the typical pattern — worth flagging to your doctor before the next step-down."
- "On the days you logged poor sleep, your next-day anxiety scores were roughly 60 percent higher. Sleep looks like the highest-leverage thing to stabilize right now."
- "You have been logging a slow-rising headache pattern for ten days, starting four days after your dose increase. If it doesn't resolve, this is worth raising with your prescriber."
- "You added a new prescription on Friday. There are no flagged interactions with your current stack, but the timing overlaps with one of your existing doses — consider spacing them."
This is the part of the product that is genuinely hard to do well, and the part that is impossible to do at all if your AI runs in someone else's cloud. The signals are private enough that handing them to a remote model is the wrong default. The model has to run locally, with your data, on your iPhone. That is what we built.
The design choices behind it
A few decisions worth flagging because they were genuinely contested internally:
On-device storage, no cloud sync. This is the single biggest constraint we put on ourselves. It is harder to build — there is no central database to debug against, no analytics dashboard showing what users are actually doing, no easy backup story. We chose it anyway because medication lists reveal diagnoses, mental-health treatment, chronic conditions, and prognoses. That data should never live on someone else's server.
Export is a first-class feature, not an afterthought. Almost every medication-tracking app we evaluated treated export as a checkbox feature, if it existed at all. We treated it as the reason the app exists. The PDF you export from Taper AI is designed to be skimmed by a physician in 30 seconds and used during the conversation.
Free, with no subscription wall on core features. A pill reminder should not cost $9 a month forever. Every core medication-tracking feature is free. We may add optional premium features in the future, but the medication tracker, reminders, side-effect log, mood tracking, AI insights, tapering plans, and export are free at launch and free permanently.
Designed in collaboration with physicians. Taper AI is a tracking and planning tool. It is not a medical device. The tapering protocols are based on clinical research and best practices, and the app is intentionally designed to be used with a physician, not instead of one. The export feature exists because the doctor is supposed to be in the loop.
Mother Nature AI as the parent brand. Taper AI is a focused product on a focused job: medication tracking. The broader Mother Nature AI mission — accessible, private, intelligent health tools for everyone — is bigger than any one app. Building Taper AI as the first product in that family lets us go deep on this specific job without bending the brand around it.
What it doesn't do
Worth being explicit about the limits.
Taper AI is not a medical device. It does not diagnose, treat, or prescribe. It tracks what you tell it and surfaces patterns. Every meaningful decision about your medication should be made with your physician.
Taper AI does not replace Apple Health or a real EHR. Apple Health is still useful for fitness, vitals, lab results, and longitudinal cross-app context. EHR-grade medical records live in your provider's chart system. Taper AI is the medication-and-symptom layer that sits next to both — the part Apple Health does not handle well today.
Taper AI is iOS only. We chose iOS first because Apple SwiftData lets us deliver on the on-device-storage promise without compromise. An Android version is being evaluated and we have no announced timeline. We are deliberately not shipping Android until we are confident we can match the privacy story.
Taper AI does not sync between devices. This is a direct consequence of the on-device-storage decision. If you sign in on a new iPhone, you start fresh. We are exploring an encrypted, end-to-end-only sync option that would preserve the no-server-can-read-your-data property, but it is not in v1.
Taper AI does not train AI models on your data. Not now, not ever. The full position is in the Taper AI privacy policy.
What's coming next
A few things in active development:
- Apple Watch reminders. Reminders that buzz on your wrist instead of getting lost in your notification tray. High priority; close to ready.
- Apple Health integration. Read-only at first — pulling in your sleep, heart rate variability, and activity data so the AI insights can correlate medications against the wearable signals you already have. Strictly opt-in.
- The Mother Nature app. Taper AI is the first product in the Mother Nature AI family. The Mother Nature app — a broader AI-powered health companion that ties together the chat, the continuous monitoring layer, Memory and Journaling, and now Taper AI's medication context — is the next big release. We will have more to say about it soon.
- Practitioner export improvements. The PDF/CSV export is good. We are pushing it toward great — adding optional sections for specific specialty visits (psychiatry, primary care, oncology), and a one-line "what to ask your doctor" summary the AI generates from your data.
The bigger story is that Taper AI and Mother Nature AI are designed to fit together. The AI you talk to in the Mother Nature AI chat is great at general health questions but does not know what you take. Taper AI knows what you take but does not know your broader health context. Connecting the two — with your explicit consent — is where this gets interesting.
