The educationally valuable app 😉 · For kids 3 and up · Android
Your child feeds, strokes and bathes their pet, plays ball and hide and seek with it – and takes it for walks. Calm, without pressure, without ads. The pet never gets ill, never goes hungry and never dies.
No analytics, no device ID, no trackers. What your child plays stays on the device.
No adverts, no in-game currency, no random rewards, no subscriptions.
No e-mail address, no sign-in, no friends list. Install and start playing.
Dog and cat, all the care, all games and the walks cost nothing – for good.
Features
Big symbols, short sentences, a picture for every action. The pet reacts to everything your child does – with a wagging tail, little hearts and happy hops.
Dog or cat, 12 fur colours – real ones and fantasy colours like pink, lilac or mint –, patterns, a collar and a name. Twelve name suggestions can simply be tapped, because children don’t like typing.
“What does your pet look like?”
Feeding, drinking, stroking, brushing, bathing and sleeping – with a finger, just like the real thing. Needs drop slowly over hours and never below a friendly minimum. After a break there are no reproaches, just a big happy reunion.
“My tummy is rumbling a little.”
Throw a ball and have it brought back, take turns at hide and seek and practise tricks: sit, paw, roll over. A miss is just practice – it works more often with every try.
“Almost! Practice helps.”
Moving & step counter
The pet is happy about every walk. The phone counts the steps itself; NixTier shows them as a ring around the pet.
“Goal reached! Enough for today – time to rest.”
For parents
Behind a gate that children don’t open by accident: hold the lock for two seconds, then solve a maths question for adults.
From–to in quarter hours. During this time NixTier shows only the sleeping pet, and sounds are off.
Off or 15 to 90 minutes. After that the pet has a rest – tomorrow you carry on.
From 1,000 to 10,000 steps a day, to suit your child’s age and routine.
Hold for 2 seconds plus a maths question. Three mistakes, then a 30-second pause. Extras, updates and the website link are only here.
“Shh … Bello is asleep.”
Safety
We built NixTier the way we want it for our own children.
No notifications, no streaks, no countdowns, no “your pet misses you”. The pet never gets ill and is never sad – at most it would like something.
Pet, name, care, steps and settings stay on the device. No account, no cloud backup, no analytics, no crash reports.
Checking for updates and verifying an unlock code. Only the code is sent – no device ID, no cookies.
No chats, no friends feature, no free text input except the pet’s name. Links to the outside only in the parent area.
No prices and no buy buttons in the children’s part. Purchases happen only on this website, only by adults.
All sounds are self-made and moderately loud. A clearly visible sound switch, silent when the phone is muted and at bedtime.
All details are in the privacy policy.
Extras
If you like, you can unlock more for good. Buy once, keep for ever: no subscription, no in-game currency. In the app your child sees no prices and no buy buttons – only a small lock on the new animals.
All three packs for €3.99 – worth it as long as you haven’t bought a pack yet. Final prices. No VAT is charged under § 19 UStG (German small business rule).
Choose a pack on this website and pay with Stripe (card, PayPal, Apple Pay, Google Pay …).
You immediately receive an e-mail with the unlock code, a link and a QR code.
In NixTier, hold “Parents”, solve the maths question, open “Extras” – open the link, scan the QR code or type the code.
“Your parents can unlock this.”
FAQ
We say it with a wink – and still mean it. The pet is happy when your child moves, takes care of it and (from age 8) does sums and reads. No ads, no in-game currency, no pressure, and no pet that gets sick when someone skips a day.
Whether that counts as “valuable” is up to you. We think a dog that only wags when you've been outside is a pretty good start.
None. The pet, its name, the care, the steps and all settings are stored only on the device and are not backed up to the cloud. There is no account, no advertising, no analytics and no trackers.
The app goes online only to check for updates and to verify an unlock code. Our server technically sees the IP address; we delete the access log after 48 hours. More in the privacy policy.
For children aged about 6 to 10. Every action has a big picture, sentences are short, hardly any reading is needed. Younger children are best playing together with you.
On Android phones and tablets with Android 8 or newer, in portrait mode. For steps the device needs a step sensor (most phones have one); without it there is the hopping game.
NixTier currently doesn’t come from the Play Store but as an APK file directly from us. Android therefore asks once whether your browser may install apps:
The wording differs slightly between manufacturers. The app is signed with our own key; the checksum is on the download page.
NixTier checks for a new version itself when it starts. Your child only sees the note “New! Ask your parents”. Updates are installed only in the parent area with “Download and install” – the first time, Android asks whether NixTier may install updates, and it confirms every installation. Pet and settings are kept.
Only adults buy extras, here on the website: choose a pack, enter your e-mail address, pay with Stripe. The unlock code arrives by e-mail straight away. In NixTier under Parents › Extras you open the link, scan the QR code or type the code. Everything is a one-off, permanent unlock – no subscription.
No. There are no prices and no buy buttons in the app. Purchases happen only on this website, after confirming that you are of age.
No problem: under Resend code you enter the e-mail address used for the purchase, and we send all valid codes there again. The code also works after reinstalling and on other devices in your household.
Nothing bad. The pet might like something to eat – and is overjoyed when your child comes back. No reproaches, no lost points.
Yes, that is planned and will come later. Until then NixTier is available as an APK directly from this website. In the Play Store, purchases will then go through Google.
Not yet. NixTier is currently available for Android only.
NixTier is free. Download the app straight onto your child’s device – or scan the QR code with your phone.
