For medicines, vitamins, and supplements
A drug interaction checker app that knows what you take
Most interaction lookups check one pair and forget you. Tavita keeps your list, so every new medicine, vitamin, or supplement gets checked against everything else you take. Dangerous pairs get flagged before you take them, and reminders tell you when each dose is due.
It's a second check to bring to your doctor or pharmacist, not a replacement. Food, water, and cycle tracking live in the same app.

How it works
Set it up once. Then it takes seconds a day.
What you get
Your meds first, then everything around them
Medicines and supplements come first. Food, water, and cycle tracking sit in the same app, so you can see how it all fits together.

Drug interaction checker
Every new pill, checked against the rest
Add a medicine or supplement and Tavita checks it against your whole list: medicine with medicine, medicine with supplement, and supplement with supplement. It draws on over 15,000 known interaction pairs.
The instant check is free and works offline. It stops you on the most serious combinations, and your schedule's safety report goes further to cover moderate ones. If you're pregnant or nursing, it also flags supplements and herbs to avoid.
Treat it as a second check to raise with your doctor or pharmacist, never a replacement.

Reminders and timing
A daily schedule built around you, not a label
Tavita builds your schedule around when you wake, eat, and sleep, then reminds you when each dose is due. It keeps iron away from calcium and pairs fat-soluble vitamins with a meal.
Mark each dose taken or skipped. Add a pill count and you'll get a heads-up before a bottle runs out. Free includes one schedule build a month, and Pro rebuilds it whenever your routine changes.

Meal logging
Snap a photo, see the whole plate
Point your camera at a plate and Tavita works out what's on it, then logs the calories, macros, and micronutrients. Hands full? Say what you ate out loud instead.
Photo and voice logging come with Pro, and you can try each one free. Barcode scanning and food search are free for everyone.

Hydration and goals
Targets tuned to your life stage
Tavita tracks water, caffeine, and alcohol alongside food. It sets micronutrient targets from your age, sex, cycle, and goals instead of one-size-fits-all numbers, and the All Nutrients view shows where you stand on each one.
Your water tracker grows a little plant through the day. It feels more like tending something than hitting a quota.

Body nutrition map
See what your food is doing for your body
Tap your heart, brain, skin, or any of fifteen body areas. You'll see which nutrients support it, which ones your recent meals have left short, and, for your kidneys, which ones they have to clear.
So instead of "you're at 60% of your zinc target," you see what that means for the parts of you that you care about.

Trends and insights
See what's actually working
Weekly and monthly reports read like a check-in with a coach: what went well, the one thing to work on next, and how your momentum compares to the stretch before. Pro adds a written AI insight report each week.
When your own data shows a real pattern, like your sleep tracking with your evening caffeine, Tavita points it out. When the evidence isn't there, it stays quiet instead of guessing. Apple Health and Health Connect sync keep it all in one place.

Progress journal
Proof of progress the mirror can't show you
Day-to-day change is hard to see, so Tavita keeps a private photo journal. Import older photos from your gallery to backdate your starting point, then slide between any two moments with the before-and-after reveal.
When you're proud of how far you've come, you can share a clean side-by-side card. Only if you want to.

Challenges and friends
Consistency is easier with company
Join a public challenge or start a private one with friends around sleep, hydration, movement, or whatever habit you're building. Scoring rewards showing up, not perfection. Miss a day and you're still in it.
Wins earn XP and badges. You decide which health areas other people can see, and everything else stays yours.
Where the data comes from
Built on published health data, not guesswork
Tavita's interaction library holds over 15,000 known pairs drawn from FDA labels, NIH sources, and published research. Medicine names, supplement labels, and food data come from the public U.S. databases below. AI only steps in to explain or classify the rare pair those sources don't cover.

Your daily inputs
Your medicines, supplements, and daily routine.

Trusted U.S. databases
- NIH DSLD
- NLM RxNorm
- openFDA
- USDA FoodData

Safety and timing checks
Every item checked against 15,000+ known interaction pairs.

Your daily schedule
Doses timed around your day, with reminders.
Public sources you can check yourself. Tavita is an independent app and isn't affiliated with or endorsed by NIH, FDA, or USDA. Their names appear only to credit the data.
A note on accuracy
I'm not a pharmacist or a doctor, so Tavita doesn't invent medical advice. It leans on what's already published in trusted U.S. health databases, the same NIH and FDA references clinicians and researchers use.
A fixed set of rules arranges your doses around those facts. AI reads your labels and helps organize the timing, but it never decides on its own what's safe for you. If a combination isn't in those databases, Tavita shows a clearly labeled estimate instead of a false all-clear.

Real routines
Built for days like yours
Tavita fits into the day you already have. You don't have to build a new one around it.

Morning
Vitamins with breakfast, already checked against everything else she takes.

Midday
Lunch logged before the first bite. One photo covers calories down to micronutrients.

Evening
A walk, the water goal met, the streak intact.
Why Tavita
Made to be trusted with your meds
No account, no ads, no trackers
Your health log lives in a database on your phone, and you can lock it with a PIN, Face ID, or fingerprint. We don't keep a copy on our servers. A few features, like AI scans and backups, send specific data out to work, and our privacy policy lists every one.
Nothing to sell you
Tavita doesn't sell supplements, run ads, or take a cut of anything you buy. Pro is a plain subscription, so the safety checks answer to you, not a storefront.
Built around your real day
Your schedule comes from your own wake, meal, and sleep times, not a one-size chart. When your routine changes, rebuild it: once a month on the free plan, anytime with Pro.
Encouraging, never clinical
Streaks, badges, and daily quests are there to cheer you on, not guilt you. Miss a day and you just pick up where you left off.

FAQ
Quick answers
The short version. Support has everything else.
Is Tavita free?
Yes. Tavita is free to download and use. The instant interaction check, barcode logging, food, water and cycle tracking, and one schedule build a month (with reminders) cost nothing. Tavita Pro is optional and adds the AI features: label scanning, photo and voice meal logging, schedule rebuilds anytime, and a weekly insight report. It's $12.99 a month or $59.99 a year.
Do I need an account?
No. There's no sign-up and no login. You open the app and start adding what you take.
How does the drug interaction checker work?
When you add a medicine or supplement, Tavita checks it against everything else on your list, using a built-in library of over 15,000 known interaction pairs. The instant check is free, works offline, and flags the most serious combinations right away. The safety report that comes with your schedule also covers moderate interactions.
How accurate are the interaction checks?
The library draws on FDA labels, NIH sources, and published research. If a pair isn't in it, Tavita shows a clearly labeled estimate instead of a false all-clear. No checker catches everything, so bring anything it flags to your pharmacist.
Does Tavita replace my doctor or pharmacist?
No. Tavita is a second check to raise with them, not a replacement. It organizes the timing of what you already take and never diagnoses, treats, or recommends doses. Your doctor or pharmacist's advice comes first.
How do I add my medicines?
Type the name or scan the barcode. Barcodes work best for supplements, since prescription bottles are rarely in barcode databases. With Pro, you can scan a medicine or supplement label and Tavita reads it for you. Tavita doesn't identify loose pills by how they look.
Is my health data private?
Your health log lives in a database on your phone, and we don't keep a copy on our servers. There's no account, and Tavita runs no ads or trackers. Features that need the internet, like AI scans and voice logging, send only what that feature needs. If you turn on the optional community features, a smaller set of data lives on our servers so they work. Our privacy policy lists all of it.
How accurate is photo meal logging?
It's a fast estimate, not a lab measurement. Tavita shows you what it found so you can adjust portions before you save.
How do cancellations and refunds work?
Cancel anytime from your phone's subscription settings. Apple and Google bill you directly, so refunds go through their stores too.
