Lven for Android
A floating bubble over other apps. Tap, speak, and Lven delivers text to the focused field. Lven types what you said, with the punctuation — it does not rewrite you.
Download directly
This is the official direct release build from ClassEve rather than the Play Store channel. Android asks you to approve installation from your browser or file manager.
If you already have Lven from Google Play, uninstall it first — this build installs separately. That clears your local history and taught words, and you sign in again.
The first build below is for arm64 devices; the second is for older 32-bit ARM hardware.

- When you open the downloaded file, Android may warn that installs from this source aren’t allowed yet. Tap Settings, turn on Allow from this source, then go back and tap Install.
- Open Lven and grant the microphone permission. Enable “display over other apps” if you want the floating bubble. Enable Accessibility only if you choose the current cross-app text-insertion beta; its exact data boundary is described below.
Missed one? Turn it on by hand — the permissions screen sits in a slightly different place depending on your phone:
- Samsung: Settings → Apps → Lven → tap the ⋮ menu (top-right) → Permissions. Grant the microphone permission; “Appear on top” is under Special access.
- Xiaomi / Redmi / POCO: Settings → Apps → Manage apps → Lven → scroll down to the large Permissions button. Some versions place overlay access under Other permissions; Autostart may help only when the phone stops the bubble.
- Pixel / OnePlus / Motorola / others: Settings → Apps → Lven → Permissions for microphone access. Overlay access is usually under Special app access → Display over other apps.
Internet for setup and account checks
The model downloads during setup or repair. Entitlement and account-token checks continue afterward, including scheduled refresh work. Transcription itself stays on your phone, and microphone audio is not uploaded.
Microphone
Built-in mic or any connected headset. Standard Android audio capture.
Overlay and Accessibility beta
The current beta uses Draw over other apps plus Android Accessibility to keep the bubble available and insert text into the focused editable field. It uses local Accessibility events and active-window checks to find that field; Accessibility-derived window content is not sent to ClassEve. A manual-copy mode that does not require Accessibility is planned.
