The shared drawing canvas
Most drawing apps for couples let you send a finished picture. HeartTap does that, and it also does the thing that is considerably harder to build and considerably better to use: a live shared canvas where both of you are drawing on the same surface at the same time.
You see their strokes appear as they make them. They see yours. What comes out at the end was made by two people rather than sent by one, which is a different experience from trading completed doodles and is the closest a phone gets to sitting at the same table with the same piece of paper.
Live sessions
Start a session and your partner joins. Both of you draw at once, in real time, with each other’s strokes appearing as they happen. The canvas shows who is connected.
Send a drawing to their widget
Any drawing can go straight to your partner’s home or lock screen widget, so a doodle made in thirty seconds is on their phone before you have put yours down.
Proper tools, kept simple
Pencil and brush, a colour palette with a full picker, adjustable stroke width, a fill tool, undo and a choice of background colour. Enough to make something, not so much that it becomes a design app.
Drawings are replies too
A drawing can answer a photo, a question or another drawing. They land in the shared timeline where either of you can react or reply, so a doodle can start a conversation rather than ending one.

Frequently asked questions
Can we really draw at the same time?
Yes. The shared canvas is a live session rather than a turn-based exchange, so both of you draw on the same surface simultaneously and see each other’s strokes as they are made.
Does drawing work between iPhone and Android?
Yes, in both directions. The drawing logic is shared between platforms, so a drawing made on Android renders the same way on iOS and lands on the widget either way round.
What happens if one of us loses connection mid-session?
The canvas keeps what has already been drawn. Whoever dropped out rejoins and picks up from the current state rather than starting again.
Do I need to be good at drawing?
No, and it works better if you are not. The value is that a drawing is unmistakably made for one person and cannot be sent thoughtlessly, which is exactly why couples keep using the drawing long after they have stopped bothering with photos.
