When weird is almost perfect I tryed a lot (all?) database app on Android available. I was looking for something like MyStuff2 on iOs. I wanted something that let me create database for my complex RPG as I always take a lot of notes, from where can I find an item, a monster... This app look strange. I don't know why creator did not use the "official and normal" inputs and ways to interract with a "normal" app... but it work great! I realy like that I can, like on MyStuff2, customize the display by adding a second field. This is one of the most important feature I was looking for, as I don't want to always open an item to see a specific second value. So this is great. This app is full of cool features, but you have to figure out where they are and how use them. The pro version cost less than 2$ so I paid for it because I feel this app will grow and with some visual tuning, can be the best database for custom use on the store.
.fix a bug with field of type "Image" when created manually.
