In-app purchases & tons of ads - constant nagging to buy paid version ($60/yr). Terrible for beginning any language that doesn't use the Roman alphabet. Low on cultural awareness, cookie cutter approach doesn't work well for many languages. Speech recognition randomly fails. Words and sentences recycled mercilessly decreasing utlity and enjoyment of this app. Bottom line: OK for drilling grammar. Supplement with other apps & reading for vocab building if you want to be able to communicate.
