I just gave it a quick spin on mobile and have some feedback.
Firstly, the idea is great. Currently, I just have a big folder full of receipts and dyno reports, and I sometimes find myself rifling through them to remember what I had done and when. Being able to access this at any time would be great.
investing the time/effort into rifling through these papers and creating my own database of mods would be time consuming and potentially cumbersome, so I was interested in how your app could help that process.
This will be one of the biggest barriers for most folks, I imagine. The bulk inserting of items. Currently, you have to do it one at a time, going to a new screen and hitting save each time. this ends up being more cumbersome than a spreadsheet. Providing a UI for bulk adding, maybe in a table style, could help you lower the effort bar and make your app competitive against other options such as keeping lists in spreadsheets or text notes.
I also don’t understand the language of a Loon. Is this a common term?
I’m a UX/UI designer, so if you’re interested in any other feedback, lemme know.
