Výtečná aplikace, díky níž jsem se zbavil nepříjemného přijímání telefonních čísel z call center, různých průzkumů a jiných otravů. Je tu výtečná možnost přidávat do jejich databáze další čísla a vytvářet si vlastní seznamy nevyžádaných čísel.

Nic to nedela


Aplikaci jsem stahnul, potvrdil predplatne, v nastaveni dle pozadavku pri instalaci jsem povolil aktualizace na pozadi a nic, kdykoli aplikaci pustim, otevre se obrazovka "Vyzkouset", no tak na to kliknu a nasledne me appka upozorni, ze uz ji mam koupenou a vrati mne zpet na "Vyzkouset" a tak porad dokola...
