4V3D

A family app studio · Tallinn, Estonia

Seriously good apps from the land of the unicorns 🦄

We're 4V3D, a small family dev company in Estonia. We don't build apps to farm your attention. We build the ones we wanted at home and couldn't find done right: chores that finally get done, nights you won't regret, a fair little game for two, a diary for the pets, every dinosaur ever and a flag for every country.

Minute Mission

For families and daycares · iPhone, Android and web · 33 languages

Chores can now grant wishes.

No more nagging, no more "I already did it!" Every chore becomes a mission worth points, and points buy the wishes your kids actually care about: screen time, sweets, a day out. You set the missions and the prices. They do the rest, and suddenly the bins go out on their own.

Free for one child, five missions and one reward. No card needed.

  • ⭐Missions pay in pointsMake the bed, walk the dog, homework. Each one worth what you decide.
  • 🎁Points become wishesScreen time, a treat, a trip. Kids save up and choose for themselves.
  • ⏱️Mission timerTurn "tidy your room" into a race against the clock.
  • 🌅Morning to eveningMissions sorted into morning, anytime and evening, so the day has a rhythm.
  • 📶Works offlineOut at the summer cottage with no signal? Keep going, it syncs later.
  • 🔒Grown-ups run itNo child accounts, no ads, no trackers. Kids never need a phone of their own.
  • 🏫A web version for daycares and kindergartensTeachers already notice the good things. Now they add up: a shared star board for the whole group, working toward a reward together. 25 € per group a month, 30 days free. See Minute Mission for daycares →

Dont You Do It

For grown-ups, after dark · iPhone and Android

Let the morning decide.

That text to your ex. The 2am shopping cart. The reply you'll regret by breakfast. From 8pm to 8am, the apps you picked in daylight stop opening. Whatever you still want to say goes into a vault until morning, and in daylight you decide if it was ever a good idea.

Free for one app, and nothing at night is ever behind the paywall.

Couples Jar

I will if you will.

You write what you'd love them to do. They do the same. You agree what everything's worth, then you both go and earn it: breakfast in bed, a lie-in on Sunday, an evening that's all yours. It's the sweetest deal you'll ever make, and you both get to win.
