Helló, Szeretnénk egy olyan android/ios appot készíttetni, melyet utána könnyen duplikálhatunk azért, hogy más logó és név alatt további appokat hozzunk létre a későbbiekben. Tehát a funkciók megmaradnak, a motor a háttérben ugyanaz, viszont más a témakör amit feldolgoz. Az appban három szereplő van: User, Services provider és mi akik adjuk az...ilyenkor felajánl egy "borravalót" melyet a user elfogadhat, ezek után apija lefut a háttérben és az összegeket szétbontva tovább utalja az SP-nek és nekünk is. Kell hozzá GPS, az alap k&eacut...

...ugyanennyi fényt ad. Sajnos kevesen ismerik, ezért mind a mai napig az eladott új lámpák többsége is elavult, T8 típus. Miért? Mert a vállalkozó, aki beszereli vagy beszerelteti, abban érdekelt, hogy olcsó legyen, az üzemeltetési költséget pedig nem ő fizeti. Egyre ismertebbek a LED-ek, amelyek között ma már tényleg vannak jó minőségűek, ezek ára azonban olyan borsos, hogy a legtöbben nem tudják, vagy nem akarják megfizetni. Van egy megoldásunk, ami lényegesen olcsóbb és gyorsabban megvalósítható mind a LED-nél, mind pedig a lámp...
