Is it a bug?

There’s a moment every app team knows, but rarely designs for. Something fails. A screen freezes. A button does nothing. The user taps again, waits, closes the app, opens it again. And sometimes, they shake the phone. Not because people think it will fix the problem, but because... yeah, I know. We have all done it.

Aikido says: do not fight the force. Redirect it. That is what this “feature” does.

Instead of asking a frustrated user to calm down, find the Help Centre, choose a category, and explain what happened, it takes the reaction already happening and gives it somewhere useful to go. Shake the phone, and the phone shows: “Is it a bug?”

Most products are designed for the calm user: someone with time, patience, and enough attention to follow the intended flow. But products rarely fail when users are calm. They fail when someone is trying to pay, send something important, catch a train, needs a taxi ASAP, finish a task, or simply move on with their day.

At that point, asking them to write a proper report isn’t support. It is homework.

The interesting part isn’t the gesture itself. It is the decision behind it. Someone noticed that frustration has a physical language. We tap twice. We refresh many times. We go back and forth between screens. We close and reopen. We shake the phone. These actions aren’t always mistakes. Sometimes they are the clearest signal a product can receive:

I don’t know what is happening, and I don’t trust this anymore

Good design doesn’t always mean teaching users a new way to behave. Sometimes it means noticing the behaviour that is already there and building a useful response around it.

That doesn’t mean every reaction should become a hidden feature. A shake can be accidental, inaccessible, or conflict with another interaction. There should always be a visible alternative. But the principle is worth keeping: design beyond the happy path. Design for the moment when the user stops following it.

Because when something breaks, people don’t want to become testers, support people, or experts in your app. They want the product to notice.

And sometimes, before leaving, they shake their phone.
