Words get used differently in different countries. But yes, ok, poor choice.
My point still stands. The only place that you might possibly get some satisfactory response to your issue is Support. We, on the forum, are only users like you. We have no ability to assist you with the app.
Also, worth noting that when talking sous vide there is no real difference if food is cooked for an extra hour. The timer on the device, and the app form that matter, can be completely ignored, they are only a courtesy reminder. If you really require a timer for your own comfort sake you can use a standalone timer.
