Common questions
What do I need to run Lingua AI?
An iPhone or iPad with iOS or iPadOS 17.0 or later, and about 3 GB of free storage for the built-in AI model (the download itself is about 2.5 GB). For the smoothest experience we recommend a device with 6 GB of RAM or more (for example iPhone 15 or newer, or an iPad with an M-series chip).
The app feels slow or the AI takes a moment to reply
Lingua AI runs a full language model on your device. When the app opens it first loads the model into memory, which can take a few seconds; after that, replies are quick. Newer devices with more memory run the AI faster and with a larger context.
Translation or chat isn't responding
Try closing and reopening the app so the model reloads. Make sure your device has enough free storage and memory (close other heavy apps). Because the AI is on-device, an internet connection is not required for it to work.
Camera or microphone isn't working
These features need permission. Open iOS Settings → Lingua AI and make sure Camera, Microphone and Speech Recognition are enabled. You can also revoke them there at any time.
Voice input isn't available for my language
To keep your voice on your device, Lingua AI uses only Apple's on-device speech recognition and never sends audio to a server. Which languages can be recognized offline depends on your device; if a language isn't supported, voice input is turned off for it and you can type instead.
I'm not getting my daily reminder
Enable notifications in iOS Settings → Lingua AI → Notifications, then set your reminder time in the app's profile. Reminders are scheduled locally on your device.
How do I change my language or level?
Open your profile from the top-right icon in the app. You can change the language you speak and the language you're learning, pick a different CEFR level (A1–C2), and change your daily goal at any time.
How do I remove my data?
All of your learning data is stored only on your device — we never receive it. You can erase it with Reset all data in your profile, or by deleting the app. See our Privacy Policy for details.
Are there ads or in-app purchases?
No. Lingua AI has no ads, no subscriptions, no in-app purchases and no tracking of any kind.
