I was one of the people who voted to close your original Question because I felt it contravened this guideline from the GIS SE Help
Avoid overt self-promotion.
The community tends to vote down overt self-promotion and flag it as
spam. Post good, relevant answers, and if some (but not all) happen to
be about your product or website, that’s okay. However, you must
disclose your affiliation in your answers.
If a large percentage of your posts include a mention of your product
or website, you're probably here for the wrong reasons. Our
advertising rates are quite reasonable; contact our ad sales team for
details. We also offer free community promotion ads for open source
projects and non-profit organizations.
You have since edited your Question, which is good because that is the way Questions are improved and can be brought on-topic, and removed your product name and invitation to participate in a free trial. Including a product name is not a problem per se - it was the marketing spin that I perceived to go with it that caused issue for me.
I have just reviewed the current state of your Question and I would still vote to Close it, but my reason for doing that is because it remains too broad. I think this because a good Answer to your Question would need to not only name one or more apps, but also make at least cursory reference to how its/their main functionalities (provide):
- support for android-tablets and/or iPads
- export your own maps directy from ArcGIS Desktop
- full offline use
- add polygons, points, lines
- add notes, photos, videos
- re-import changes made on the go.
AND how they do this with a focus on:
- ArcGIS Desktop
To me, your Question, is effectively asking at least six (and probably more) questions and, although each could be asked alone, I think answers to most of these can already be found by searching GIS SE so would add little in the way of new Q&A content.
Incidentally, I (and I suspect many others) already use GIS Stack Exchange for market research but I do that by mining its invaluable data.
