Estimated revenue

A model estimate with a likely range, not a reported figure.

No estimate. Apps outside the grossing charts, and some countries, have no reliable rank-to-revenue curve, so we show nothing rather than a guess.

How this estimate is made

Rank: we take the app's best Top Grossing rank on the latest chart day. Category ranks are converted into an equivalent overall rank, because a #10 in Finance earns far less than a #10 overall.

Curve: that equivalent rank is read off a rank-to-revenue curve anchored on public company revenue and market-data reports for the US iPhone App Store.

Country: the curve is scaled per country (Japan is roughly a third of the US, Türkiye under 1%). Where we have no scale, such as China, there is no estimate.

Range: the likely range widens with country, category and chart depth. It is a plausible span, not a statistical confidence interval.

Not included: ads, payments outside the App Store, and any difference between gross sales and what the developer keeps. Low confidence means indirect data; medium means several independent sources agree.

Tähetark on sõbralik öökull Otto, kes õpetab sinu lapsele tähti, numbreid, loendamist ja esimest matemaatikat - mänguliselt ja teaduspõhiselt.

  • Otto juhendab kõike häälega, laps ei pea lugema
  • Eesti tähestik häälimine-meetodil ja inglise tähed foonika järjekorras
  • Tähtede ja numbrite kirjutamine sõrmega
  • Loendamine, kiirpilk, võrdlemine, liitmine ja lahutamine
  • Vahedega kordamine kinnistab õpitu püsimällu
  • Raskus kohaneb lapsega, iga seanss lõpeb eduelamusega
  • Kleepsud päriselt selgeks õpitud oskuste eest
  • Töötab täielikult ilma internetita

Privaatsus ennekõike: ei reklaame, ei jälgimist, ei andmekogumist. Loodud ühe isa poolt oma 4-aastasele pojale, tuginedes lugemis- ja matemaatikaõpetuse teadusuuringutele.

Suur helide ja mängude uuendus!

  • Kõik hääled salvestatud uuesti — soe, rõõmus päris isahääl (kogu eesti keel)
  • Tähti õpetatakse nüüd häälikutena: K = „k“, M = „mmm“ — nii sulavad tähed sõnadeks
  • Raketimäng uuena: päris takistused, mille vahelt pujuda, ja aina põnevam
  • Kümneid parandusi mängudes: korvid, „üks ei sobi“, varjumäng, kalapüük, muusikapidu

A big sound and gameplay update!

  • Every voice re-recorded — a warm, happy real dad's voice (all of Estonian)
  • Letters are now taught as sounds: K = "k", M = "mmm" — so letters blend into words
