Landlord HQ is an android app I wrote for managing property on an Android device. The website for it is here and the Google play store entry is here.
The project was a reasonable success, I haven’t advertised it so it doesn’t have a lot of users but I’m happy with the result. I can use it myself and it supports most of what I set out to do in the beginning, and I got to learn a few new things I hadn’t used before (Android, building REST APIs, CouchDB etc).
It’s about 20,000 lines of Java all in total and it took me close to a year to build in my free time (with a 4 month break in the middle). It supports some good features, like synchronising all data to “the cloud”, being able to properly handle and merge conflicts, and keeping all data encrypted at all times (on disk and in transfer).
It’s by no means feature complete, and it definitely needs a web version built. Being able to view data on a phone is extremely handy, but data entry on a phone is … not so great. I’ve been doing some projects at work recently with Angular2, so I’d be comfortable building a web front end for it. I just haven’t found the time yet =/
