CodeMosaic

Create practical QR codes from information you choose, right on your device. Create codes for: • Plain text and personal notes • Website addresses, with basic format checks only • Phone and email contacts, with an optional contact name • Wi-Fi network details Review a live preview before you use a code. Adjust error correction, quiet-zone margin, and high-contrast color. If content is too large for the selected settings, the app explains the issue and prevents saving or exporting an invalid code. Copy the encoded content, save a QR project on your device, or export a clear PNG through the Android system share sheet. Saved projects can be searched, renamed, edited, deleted, and restored from recently deleted items. Preferences include export size, appearance, and optional recent history. Your content is encoded locally. No account, upload, camera, scanner, or website access is required. Website addresses are not opened or checked for safety. Wi-Fi codes contain sensitive network details and are excluded from recent history; saving one requires your confirmation.
