I’ve looked for crafting apps on google, there were some ideas and plans on creating one. But I still can’t find one. I’m not sure if Arenanet self is interested in creating this app. I don’t have the tools yet to do so myself. I do have some ideas on how I would make it.
1: the in game crafting interface
2: planning your whole crafting progress, from 1 to 400
3: required materials log, I did level crafting myself to 400 by printing a guide and buy order all materials over 1 week. And made a lot in 1 hour with a booster.
4: make everything available and searchable (discovery’s and recipes), maybe you will think this is a spoiler. But, people can always search the Internet, and since Arenanet likes to make things easier for people, why not create a good app.?
5: maybe it is possible to link your inventory to your app. and see what is still required.
There might be a lot more possible, and I also heard there was a trading post/guild chat app. under development, maybe it can be combined?
