I had shortlisted LeanKit before 2012 after getting a quick overview of the different tools. I also liked Trello very much, but LeanKit spoke to me immediately. I think it was mainly the possibility to hide backlog and archive and the design possibilities at the lanes, which had done to me. True to the motto "Try it" is about studying so I put my new LeanKit board into operation at the end of April.
The department can be organized. The department can also be displayed transparently. Projects can be started and transferred to other areas of the company. The possibility to divide horizontally Lanes, I find very helpful. It opens up a wide variety of possibilities in the design of the board and has an extremely positive effect on the clarity! A feature that I definitely do not want to miss anymore!
When it comes to customizing the board structure, I was very pleasantly surprised how good it works on the iPad via the webapp. Only the "Card Styles" can not be adjusted here. The iOS app does not offer this functionality either, but that does not bother you, because you do not always make these adjustments.
The only drawback with the iOS app: The editing works only with Internet connection, which makes it sometimes difficult to use travel times for planning! PRO: WIP limits, design options and notifications make the tool very appealing to me.
iOS App and Webapp are very comfortable to use.
Changes can be made quickly, so no idea is lost.
CON: I would like to be able to use IFTTT because I do not want to spend the cost of Zapier for private purposes.
Regular tasks can not be mastered either.
Both would not be a problem if you could create maps by email. This is the biggest drawback in my opinion!
