How to zoom in or zoom out with one hand in Organic Maps:
1. Tap quickly twice anywhere on the map, but don't lift up a finger after the 2nd tap.
2. Move your finger up or down to zoom in or zoom out.

Long Tap gesture: shows or hides the interface.

@organicmaps Holy shit! That's neat!
@organicmaps
That's great!
I would consider adding this as a tooltip or so...
@organicmaps @ingonymous I second this idea. Simply because people aren't use to this way to zoom in or out.
@mythlfrythtyg @organicmaps @ingonymous It's a pretty standard feature. Apple Maps and Google Maps on iOS have both always had this.

@blobjim @organicmaps @ingonymous "on iOS" Ok, then I know why it doesn´t work for me.
Never had an apple and

However, this does not rule out a tooltip, at least in the Android version.

@mythlfrythtyg @blobjim @ingonymous this feature is/was available on iOS and on Android. What is not working for you? The video in the post is from an Android device.

Muhaha... 😂
You see what I mean?
I cannot speak for iOS but for Android I would say it's a super unusual gesture. At least I would never had thought of that.
@ingonymous
Me? Absolutely.
Never read or heard of this method before.
Thank g I hadn´t had the time to answer to above posting. Could´ve ended in a tl;dr text.

@organicmaps Just tried this out. Fantastic! I've been traveling with #OrganicMaps for the past week and this is going to help a lot when I have my hands full. Thank you!
@organicmaps
Pretty amazing, for example on the bike it is really hard to pinch, but this works very well. Thanks for the heads-up.
