Lumen trails is a very well designed and highly useful app. I actually have more than one version because I use it so often and for so many things - one for personal tracking, the other for work related items, lists, etc. The app is beautifully customizable which makes it handy for almost anything. I have been using Lumen Trails daily now for almost a year and still havent utilized the full possibilities of this high quality, extremely stable and useful app.
