linguaArbor
iOS app by Phivolt Srls
linguaArbor helps you learn a language step by step along a clear, CEFR-structured path (levels A1, A2 and B1), using high-quality, natural-sounding voices from your device (Apple's built-in voice synthesis), six interface languages (German, English, Spanish, French, Italian, Portuguese) and a variety of exercises — multiple choice, word bank, image matching, listening, pair matching and optional speaking practice. You learn at your own pace, without aggressive streak pressure.
All course content and audio are free. The optional Premium subscription removes ads and gives unlimited energy ("leaves") so you never wait to keep practising: €4.99/month or €24.99/year (prices may vary by region, shown in your local currency at purchase). It is an auto-renewing subscription charged to your Apple ID; it renews unless cancelled at least 24 hours before the period ends. Manage or cancel anytime in iOS Settings → your name → Subscriptions, and restore a purchase from the Premium screen in the app.
