Keyboardrop keeps what you copy as "drops" and lets you paste them anywhere from a built-in keyboard or the share sheet, and hand them to another device via QR.
Setup
Settings → General → Keyboard → Keyboards → Add New Keyboard → Keyboardrop
Open Keyboardrop again and turn on Allow Full Access (required to save the clipboard)
How to Use
Save: the keyboard's Save button / Keyboardrop in the share sheet / "Save current clipboard" in the app
Paste: open the Keyboardrop keyboard where you want to paste, then tap a drop
Send to another device: touch and hold a drop → "Send via QR" → scan from "Receive a drop" on the other device
Auto-delete: choose 10 min / 30 min / 1 hour / 1 day / manual in Settings (default: 1 day)
FAQ
Why does the keyboard need Full Access?
Only to read and save your clipboard. It never logs your typing or sends it anywhere.
Where is my data stored?
Entirely on your device. Nothing is sent to a server.
Does it use the network?
Only to fetch the preview image/title for a saved URL.
A drop disappeared.
Drops auto-delete on your chosen timer. Set it to "manual" to keep them.
