PairInk gives your ideas room to grow. Sketch, write notes and organize your work on boards on iPhone and iPad, then connect with the Windows companion over your local Wi-Fi. MAKE YOUR MARK Draw with your finger or Apple Pencil on supported iPads. Switch between pen and highlighter presets, add shapes and arrows, and select objects with a rectangle or a freehand lasso. KEEP YOUR THINKING TOGETHER Add typed Notepad text, bring images and PDF pages onto a board, and keep your work organized in a visual board library. Pin important boards and choose a cards or grid view. CONNECT YOUR SCREENS Find nearby computers or scan a pairing QR code. Once paired, PairInk remembers the computer and can reconnect when both devices are reachable on the same local network. Live syncing requires the Windows companion to be running; connection speed depends on your network and board size. TAKE YOUR WORK WITH YOU Keep boards on your device, export PDFs and save board backups. Board content is stored on your devices; the license service verifies trial and purchase access separately. TRY PAIRINK Start a 7-day trial with up to three active boards. When the trial ends, you can continue viewing and exporting your work. A separate one-time in-app purchase unlocks unlimited boards and editing, including version 1.x updates. The trial does not automatically charge you or turn into a subscription. Pricing is shown in your local App Store currency before purchase. No separate PairInk account is required. Purchases use your Apple Account. Internet access is needed for activation and restoration; Pro access must be refreshed online at least once every 30 days. If your installation identity is lost, contact support with your store receipt for recovery. Windows syncing requires the separately installed PairInk companion and local-network access. Camera access is optional and used only to scan a pairing QR code. Support: jawadsjaber@outlook.com
