QA can’t keep pace

You ship every 90 seconds. QA inspects one release at a time.

So hard to navigate

8 Jan

Took me four screens just to find my own orders, and I still ended up searching for it.

★★★★★Raul G.

Buggy, would not recommend

7 Jan

It crashes constantly and half the buttons do nothing at all. Uninstalled after a week.

★★★★★Emma D.

Checkout is broken

6 Jan

Tapped pay three times and nothing happened, so I gave up and ordered somewhere else.

★★★★★Marcus R.

Lost my whole basket

5 Jan

Changed one item and the whole thing emptied. Had to build the order again from scratch.

★★★★★Priya S.

Product problems surface after launch

Customers become the feedback loop when QA cannot keep up with release velocity.
