How to zoom in and out

[Gerbrand333]

This is my problem:
I am able to zoom in
bij pressing on the chart but how to zoom out.
I don't see any option.
Most weatherapp's have special knobs in order to zoom in and out.

Hi @gerbrand333, to use pinch-to-zoom, touch two fingers on the touch screen, and move them apart to zoom in, or together to zoom out.

@petra-pik I can second the OP issue. One-Finger double-tap zooms in. But I cannot find a single-finger / thumb way of zooming out. When holding your phone with one hand this becomes a problem. The solutions are well known: either more screen clutter by adding explicit zoom buttons or do the Google Maps thing and allow the finger to be dragged up/down on the second tap of the double-tap to indicate zoom in/out, respectively.
