Just terrible. Terrible. The interface looks like something out of android pre alpha or something. There is nothing but parts of textbooks badly organised in terrible menus. The search function isnt even functional, doesnt do anything. Save your dollar and go buy something else. Anything else.

## Sigma Matematik

Sigma Matematik har allt inom matte du kan önska dig och lite till!

Nu i samarbete med mattecentrum.se!

Matteappen Sigma är anpassad för gymnasiereformen GY2011 vilket innebär bland annat att kursnamnen har ändrats och att matematik E och matematik diskret delvis har förts samman i Matte 5.

Även om du läser matte på högstadiet eller på högskola kan du ha användning för Sigma då bland annat kurs 1 innefattar högstadiematematiken och högskolekurser så som Diskret matematik och Matematik för ekonomer delar innehåll med de högre gymnasiekurserna. Appen är dessutom perfekt för de som vill träna sin huvudräkning inför högskoleprovet.

Om du gillar appens koncept och vill att den ska utvecklas så kan du ranka appen högt och tipsa dina vänner!

Tack!

Teknisk information:

★Sigma stödjer de vanligaste skärmupplösningarna, bland andra QVGA, HVGA och WVGA.

★Sigma fungerar för Android 1.6 och uppåt

★Sigma stödjer Apps2SD för android 2.2 och uppåt

★Appen begär interneträttigheter för att kunna länka till bland annat wikipedia.org och mattecentrum.se, ingen nätverksdata används så länge du inte trycker på de länkarna.

★Skrytfunktionen fungerar inte smärtfritt med den officiella Facebook appen, det är ett problem på deras sida så om du vill skryta via Facebook får du välja t.ex. att skryta via sms och sedan kopiera texten från meddelandet.

★Som sista utväg ifall appen skulle krångla så kan du "rensa användardata" i appens inställningar för att lösa det.
