Supiki English Conversation is a smartly-designed and expertly-crafted app that combines game-like elements with the conversational tools of the iPhone to teach English. The app works very well in many situations, but is often limited by the steep price of upgrades and the lack of control over which lessons you can use. For those that fully invest in Supiki, it offers many fun surprises that dabblers may not have the chance to experience.
When you start using Supiki, you can access a handful of lessons for free. Other lessons will unlock as you complete the initial ones, but because of the point-system used to determine when new lessons unlock, it will take some time before you can access higher-level content. The learning system, however, is very well designed, with high production values and a smooth interface. Most of the lessons involve speaking to the app directly, and while the feedback from the app on quality of speech is limited, the interaction is a great touch.
Supiki is a well-designed app that, while it won't teach English directly because of its vague lesson format, is a great way to practice conversing in English while alone. The cost of the additional lessons is high, but for those that complete the early content and feel compelled to go further, the app offers a range of different options and features to enhance your learning experience.
