せっかく勉強した英語を最大限に活かしませんか？ PredicTalkは、翻訳アプリに頼らずに自分の言葉で自由に英語を話せるようサポートします。 通常の翻訳アプリはスマートフォンに話しかけ、画面を相手に見せるだけで、まるで直接対話している感じがしませんよね。せっかく英語を勉強してきたのなら、自分の言葉で相手と直接コミュニケーションをとりたくないですか？ PredicTalkを使えば、通常は自分の力で英会話を進め、会話が詰まった時だけ画面を見ることで次にどう話せばいいかヒントを得られます。スマートフォンにBrilliant LabsのARグラス"Frame"接続すれば、目の前に会話のヒントが表示されるので、スマートフォンを見る必要すらありません。 PredicTalkで英会話のハードルを下げ、自信を持ってコミュニケーションをとりましょう！

Verdict
The clearest difference is ads: PredicTalk at none against Optical flow Analysis's shown. Optical flow Analysis's advantage is update cadence (fortnightly vs every 14 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
