Real proportions, light and shadow – more trading card than cuddly toy. Every creature has its own food and a quirk. Things may happen: cheeky, but never bad, never final and never something money can skip.
Astra and Nox are free; Ignis, Volt, Kiro and Marea are part of the Animal friends pack
AstraStar foxeats stardust berries – sometimes dissolves in starlight and reappears somewhere else
IgnisLava salamandereats ember crystals – when hungry, something in the hideout melts
VoltStorm dragoneats thunderclouds – a bad mood means a thunderstorm, the hideout goes dark for a moment
KiroCrystal lynxeats moon quartz – ignore him and crystals grow, stroking only after cleaning
NoxShadow wolfeats fireflies – roams at night and sometimes brings back a find
MareaNight rayeats glowing plankton – dives away in a storm and is back the next day
Transformation
Three forms – Astra as an example
Learning and movement bring levels, and the creature transforms visibly. Never reversed, never for sale – and it takes patience: the second form after about a week, the third after a few weeks.
Form 1 · Cubsmall, plain fur
Form 2 · Wildlingstar signs in the fur, the tip of the tail glows
Form 3 · Star formthree glowing tails, star crown
Maths by age
From times tables to percentages and equations
The age set in the parent area determines the starting level and the tasks – roughly following German curricula for school years 3 to 7. After that the level adapts to your child’s skills.
Parents can set it one level easier or harder
Combos and best times give extra XP, never a penalty – both can be switched off
Plus stories and quizzes for older kids – new every day with the subscription, with an archive of the last 30 days

Friends leaderboard · from 9
Better than your friends?
Connected with friends, you can see who is ahead this week – but only if you allow it in the parent area. It is off by default.
Player name built from word blocks, e.g. “Swift Star Fox 42” – no real names, no free input
Friends only via code or QR code; your child accepts requests, only friends see the scores
The list starts afresh every week
In the parent area you can see the friends list and remove friends
At age 8 there are only personal best scores, without a server
Camera
The creature in the real world
The creature appears in the camera image – on the desk or in a selfie. Move, rotate, resize, choose a pose, snap.
Photos stay on the phone – no upload, no face recognition
Only if you allow the camera in the parent area
For parents
You make the rules. The app sticks to them.
Everything important is in the parent area – behind a gate children can’t just click away: hold for two seconds, then solve a maths question for adults.
Bedtime
From–to in quarter hours. Then the pet sleeps too, and sounds get quieter beforehand.
Play time per day
15 to 90 minutes or no limit. You decide whether learning counts – otherwise learning carries on afterwards.
Bonus time they earn
Learning points and steps turn into minutes – you set how many (by default at most 60 a day, adjustable 15–180). You release the minutes yourself, e.g. in Google Family Link; the log shows the last 7 days. NixTier doesn’t block any other apps.
Weekly overview
Points per subject and steps per day, calculated on the device. If you like, compare anonymously with children of the same age – only with your yes.
Learning made to measure
Subjects on and off, font size 80–160 %, read aloud, difficulty one level easier or harder. Time pressure and combos can be switched off.
Movement
Daily step goal from 1,000 to 10,000. Counted only while the app is open, without location.
Friends and camera
Friends leaderboard (from 9) and camera (from 8) only with your permission. Your child accepts friend requests; you see the friends list and can remove friends. Switching it off deletes all of it.
Purchases only by you
Extras, codes, subscription status and cancelling – all in the parent area. Your child sees no prices and no buy buttons.
No account, no date of birth – just the age in years. No ads, no tracking.
