Safety's always free. Plus is for everything after that.

Parent-funded, never data-funded.

The allergen radar, the watch window, and reaction logging are free on every plan. Forever. Safety is never behind a paywall. Neither is the record: feeds, sleep, diapers, foods, and every first taste are yours to keep, free. Plus is for making sense of it all.

Free is genuinely complete, not a teaser. Plus is for families who want the keepsake, the coordination, and to raise an adventurous eater.

The whole daily loop
Log feeds, pumping, sleep, diapers & solidsThe core day, most of it one tap✓✓
Nursing timerStart it on a side, switch sides, pause for a burp, and tap Done. Each side logs its own minutes, it keeps time with the screen locked, and the other parent sees it running on their phone and can stop it there✓✓
Combo feedsNursing plus a top-up of pumped milk or formula, saved as one feed from the feed sheet, the nursing timer or by voice, and counted once✓✓
Fill in any diaper change laterQuick Wet and Dirty taps included: add the color, consistency, blood, mucus, a note or a blowout once your hands are free. Blowouts are counted on Diapers, Trends and the sitter page✓✓
Tummy time, baths and the rest of the dayLog tummy time, baths, toothbrushing, time outside, story time, play time or nail trims, with the minutes when you want them. Once you have logged one, it is a single tap to log again✓✓
Your usualsBuild a multi-food meal once (the multigrain cereal, the standing breakfast), save it, and log the whole thing in one tap, or tap one into a meal already started. Every food still logs individually underneath, so allergens and firsts keep counting✓✓
Import from another trackerFeeds, sleep, diapers, solids and activities like tummy time and baths come over from another tracker's CSV. It does not have to be an app we have heard of, because we read the columns rather than the name. A Nara Baby export brings the rest of the day too: temperatures, medicines with each dose's exact amount, pumping, growth, shots, combo feeds and blowouts. Free on every plan; recorded firsts from your old app wait for Plus, where the memory book lives✓✓
Fresh milk stashLog a pump and we track freshness, nudging you before it turns✓✓
Voice loggingSay it out loud, transcribed on your phone. Forgot a food halfway through? Say the rest and it joins the same meal, as many times as you need. When a word like "dairy free" or "vegan" could change the food, it asks instead of guessing, and a "no", like "no blood", stays a no✓✓
Log a whole sentence at once, said or typedSay or type "napped 1 to 2, drank 4 oz, then pooped" and log all three. Typing needs no mic, so it works anywhere you cannot talk✓✓
Log the daycare sheetRead the day's sheet out loud, line by line, or paste it, and check every entry before one tap logs them all. The recording is turned into words on your phone✓✓
Last night in one line on TodayFeeds and changes overnight, the longest gap between logged feeds on a night with a feed logged in the evening, overnight and in the morning, and a tap for every time✓✓
The last side and the last poop, right on TodayThe side you nursed last on the Fed chip, and the last poop on the Changed chip once a wet has been logged after it✓✓
Sleep "still asleep?" check-ins✓✓
Wake-window sleep insightsYour longest stretch, wake-ups a night, their own daytime wake window, and a plain note when the fully logged nights of the last week and the week before show the longest stretch moving or a whole nap dropping away. Free on every plan, and the clearest way to judge what the Plus reads do with the rest of the day✓✓
Medication & vitamin reminders✓✓
Private health photos for the doctorRash? Diaper looks off? Take the photo in the app and it never touches your camera roll. It syncs to your co-parent, and a show-the-doctor mode walks through them at the visit✓✓
Wear time for helmets, eye patches, hearing aids and bracesFor a child who wears a helmet, eye patch, hearing aid or brace: the hours on against the daily goal from your orthotist, eye team, audiologist or orthopedic team, a schedule that builds up or steps down if you were given one, times added later, skin checks with a private photo if you want one, and the full history, on every caregiver's phone. Out of sight until you turn it on, and it keeps the count without judging the day✓✓
Daily nudge & quiet hours✓✓
Safety & allergens
Allergen radar + allergen trackerIntroduce early, keep in rotation. Free.✓✓
Last-served memory on every tried foodEach food shows when it was last eaten, and the Tried list sorts the longest-away foods to the top, so nothing quietly drops out of the diet✓✓
Reaction logging (😋 / 🤢) + photos✓✓
Reaction summary for the doctor✓✓
Safety checks on every food on the plateThe allergen pill, the allergen-watch caution and the family-allergy heads-up read every food in a meal, not just the first one✓✓
A dose that cannot be right is refusedA dose of 0 or less, one with no unit, or one far above any infant dose is refused before it is saved, wherever a dose is logged✓✓
Every dose in the last 24 hoursEach medicine with its own time and amount on Today and Handoff, so a dose from 11 PM still shows at 2 AM✓✓
Meal plannerAn allergen-smart week: keeps introduced allergens in rotation and works in new flavors and favorites, one reason per meal. The watch, reactions, and knowing to keep allergens in are always free✓
What your logs sayLongitudinal reads on your own logs: bedtime drift, night feeds and feed spacing, wake-window and nap patterns, bottle-volume and night-consolidation trends, tries-to-a-win, and the log’s own anniversary, each with the data behind it. Describes your baby, never diagnoses✓

It ends with the month in numbers: hours of nursing, sleep with naps and nights apart, bottles, pumping, diaper changes by kind and blowouts, doses and activities, added up from what you logged and never estimated. Printable, and by email, notification or both on the 1st when a month brings a first taste, a milestone or a busy month of feeds and changes✓

💸 Built to help pay for itself

Plus tracks your diaper sizes and real spend, so you can see the true cost per change, spot when sizing up (or waiting) is actually cheaper, and skip the 2am “we’re out” panic order at full price. Formula price tracking works the same way, watching the cost of the formula you already buy. And when we compare prices, the cheapest price wins whether or not that retailer pays us anything, and we never steer which formula you buy. What that adds up to over a year depends entirely on how much you buy, so we will not put a number on it. What we will promise is that you can see what you actually pay per diaper and per ounce, and who is cheaper today.

📖 Worth more the longer you keep it

Day one, YummyYucky saves you a guess: which side, how long ago, how many wet diapers today. By month three it is the story of their first months: every first, and with Plus a letter on the 1st with the month in numbers. Once solids start it keeps every 🤢 that turned into a 😋, and every allergen introduced and dated for your pediatrician. Trackers you forget about. A record of firsts only gets more valuable, and the basics are yours to keep whether you go Plus or not.

Questions

Is YummyYucky free?

Yes. The whole daily loop is always free: logging feeds (with a left and right nursing timer, and nursing plus a top-up saved as one feed), pumping, sleep, diapers, tummy time and baths, and solids, by tap or by voice (a whole sentence at once included), the allergen radar and watch window, reaction logging, the vaccine record, next-nap and wake-window sleep insights, feeding and sleep trends this week versus last, catching the little moments worth keeping, medication reminders, recipes, and all of our guides. Plus is for when you want more: the monthly letter, by email on the 1st, with the month in numbers; the keepsake side (the Journey, a printable memory book, letters to your baby, and sound clips of the first laugh); milestones and what comes next; coordination tools like a private family feed, a care sheet for sitters, a while-you-were-away handoff, a read-only care summary link to share with a sitter or your pediatrician, and a weekly recap; a pediatrician-ready checkup report with visit prep; the Flavor Explorer for raising an adventurous eater; and unlimited babies and caretakers.

How much is Plus?

Plus is $99 per year, which works out to $8.25 a month, or $12 month to month if you prefer. You can cancel anytime.

Is there a free trial, and when do I get charged?

Yes. Plus starts with a 7-day free trial. We collect your card at signup so it is ready to go, but you are not charged until day 7. Cancel anytime before then and you pay nothing. The trial is a one-time offer, so it does not repeat if you resubscribe later.

Is there an app to download?

Yes. Get it on the App Store for iPhone and on Google Play for Android. You can also install it straight from your browser on any device, with offline logging, reminders, and its own home-screen icon. Visit yummyyuc.ky/install for every option.

Are safety features behind the paywall?

Never. Allergen tracking, the watch window, reaction logging, the safety checks that read every food on the plate, and the check that refuses a dose that cannot be right (0, no unit, or far above any infant dose) are always free, on every plan. Plus is for the monthly letter and the keepsakes, the Journey and recap, video clips of first tries, the Flavor Explorer, and unlimited babies and caretakers.

Do you sell my data?

No. YummyYucky is funded by parents, not their data. We don’t sell your data, ever.

Can I cancel anytime?

Yes. Cancel from your account whenever you like, and you keep Plus until the end of the billing period.
