@marcsan Not really sure what's the problem with typos and the old app. I've been using mine for reviews for 2 days exclusively (no website), and haven't made a single typo.Don't ignore your users, man. They're telling you what they want, and you're telling them how they should use the product instead. Listen to feedback; that's what you came here for, right?
Regarding the ignore button, I don't think it's possible to make one, because you can't really ignore words on WaniKani.
Here's how it looks in my app:
1. You type answer
2. YOU READ IT
3a. If it's correct, you press arrow, just like on web
3b. If it's not correct, you edit your text and then submit it
Not really sure what's the problem is.
People want to do their reviews quickly; having to read what they typed out is an impediment. The reason a lot of us shy away from using Wanikani's mobile interface and third-party apps is because we make a lot of typos on mobile keyboards that we can't correct. We use the ignore answer userscript on desktop to deal with that, or just use desktops because we make way fewer mistakes there.
Ergo, an ignore answer button may actually be a must-have feature for any Wanikani mobile app.
Sure, users need to provide feedback. But in this case, OP might have a point. If you're making a typo by typing too fast, clicking an ignore button, and then typing everything again, than how is that different/faster than just carefully looking at your answer in the first place?
But yea, you're right. I, too, am reluctant to use an app to do reviews because it doesn't have such an ignore button. I don't even think the android app has one, and that one has been in development (and production) a lot longer. It would be a glorious day if someone finally made one for mobile! I actually haven't looked into it, so don't go shouting if it turns out to be super simple, but couldn't it just be possible that such a feature is just not an easy thing to ask of a developer?
Browsers have greasemonkey and tampermonkey to handle all the magic, but with mobile you just don't have that. From what little i know, you have a component that acts like a simplistic browser, displaying the real WK site so you can do reviews, but throwing user scripts in the mix here is just something i presume to be unlikely happening.
My point being: if you're a programmer and know what you're talking about, than try to help instead of criticise, and if you don't know what you're talking about, don't criticise and be grateful to OP. And don't expect magic. Peeps always think a programmer can do anything on a computer with just a few keystrokes. I only have mad respect for OP for taking the time to make this for the enjoyment of others, so damn if anybody's trying to say him how to make his own app. He's simply owes nobody anything.
