Grow Together

What your child needs this year, laid out by age

Add a child and three threads unfold for their current age band: physical health, emotional growth and money sense. Log the day in a tap, read a stage report, and talk a question through with Wenwen. No account, no server: every record stays on your own phone.

The iOS edition is available on the App Store; the Huawei edition ships without AI features as the channel requires, everything else is identical.

Three threads that grow with the child

No pocket money at age one, no brushing check-ins for a teenager. When a birthday moves the child into a new band, the whole app changes together.

🌿

Physical health

  • Growth curves against national percentiles
  • Vaccines scheduled from the birthday, with reminders
  • Vision, teeth, outdoor and screen time logs

💙

Emotional growth

  • Main tasks and a theme for every stage
  • Parenting-style quiz, child temperament observation
  • Family activities, challenges and a memory wall
0-11-33-66-1212-18
🐷

Money sense

  • Ages 0-3: household spending and growth investment only
  • From 3: growth fund, wish savings, chores and rewards
  • A small family business game to make money make sense

Six things that make parenting feel more grounded

Everything serves one loop: profile → age-staged content and logs → stage report → AI discussion.

📅

Unfolds by age band

Content is split into 0-1, 1-3, 3-6, 6-12 and 12-18, gated by a single stage map. Compiled from Chinese paediatric and developmental-psychology standards.

✍️

Log today in one tap

Outdoors, screen time, the family activity, brushing and mood on one card, with no streak pressure. Anything that needs a form opens in one step.

🎛️

Personality growth simulator

Six parenting sliders, a nine-axis radar that updates in the same frame. Starts from your own quiz, with dots from your real logs beside it.

🍊

Wenwen, on your own AI key

Asks about today's mood, surfaces reminders and talks parenting through with you. Only the age band and allowed summaries are sent, and you see the list first.

⏰

Reminders and family challenges

Water and medicine ring on time; vaccines follow the birthday. Eye care, early bedtime and daily praise challenges run side by side with checklists.

🔐

Your data stays yours

A local snapshot every day, encrypted exports, and on iOS your own iCloud. Merge on import without duplicating a child; overwrite can be undone.

Meet Wenwen, a little orange that peeks out

It lives in a corner of the screen. It asks about today's mood if none is logged, shows a reminder above its head when one is due, and hides in its pouch if you poke it three times. Tap it to talk parenting; the model runs on your own key.

She's five and a half and cries over the smallest things lately. What do I do?
Ages 3-6 are when children learn to recognise and name feelings, so more tears aren't a step back. Your last eight weeks show good activity completion and moods around "okay". Try one thing this week: when she cries, name the feeling you see before you solve anything. Do it three times and we'll check whether the mood log shifts.

Give Wenwen a brain module

Skill packs are small one-time purchases by topic that make Wenwen sharper on that subject. The model is still your own key and data stays on the device. First topics rolling out.

Skill packs are parenting references, not medical or psychological advice. One-time purchase, yours for life, not part of Pro, model costs not included.

One purchase, no subscription

The core is free. Pro unlocks the advanced features once, for life. Skill packs are small separate one-time purchases.

What is Grow Together?

A local-first parenting companion for parents of children aged 0 to 18. It follows three threads, physical health, emotional growth and money sense, by age band, from profile to age-staged content and logs, stage reports and AI discussion. Available on iOS and Android.

How is my data protected?

There is no account and no server of ours. Every record lives in a local database on your phone, and the app contains no analytics or ad SDK. The only network call is the AI request made with your own key, which by default sends the age band and trend summaries, with a card listing each item before it goes. Backup files are yours to keep, optionally passphrase-encrypted.

Is it paid? How does pricing work?

The download is free and the basics work: profiles, age-staged content, one-tap logging and reminders. Advanced features are unlocked by Pro, a one-time purchase that lasts for life, with no subscription and no ads. Topic skill packs are small separate one-time purchases that make the assistant sharper on that topic; they are not part of Pro and do not include model costs. Prices are shown in your local store, and "Restore purchases" brings everything back on a new phone.

What does the AI need, and what does it send?

You enter an API key from a model provider in the app; usage is billed between you and that provider. Requests include only the child's age band and trend summaries within scopes you allow, such as growth percentile ranges, habit check-in days and task completion rates; never names, birthdays or exact measurements, and money data is off by default. Each scope has its own switch, and a card lists every injected item before sending.

How do I move my data to a new phone?

Export a backup from "Me → Data & backup" (the encrypted version needs a passphrase), send the file to the new phone and choose "Restore from backup → Choose a file" on the same page there. On iOS with iCloud private backup on, a new device on the same Apple ID can pick "Backup in iCloud" directly. Import offers merge or overwrite; merge never duplicates a child, and a snapshot is taken before overwrite so you can undo within 24 hours.
