[Steve App]

I have created Sticker App and looking for advise to collect the keywords for my app from any of freeware tool/website.

Most of the site is asking CC details for 1 week or 1 month free service.

I don't have CC so looking for a freeware sites.

So you're looking for help with SEO for your app? People that help with that generally like to be compensated for their efforts, hence the need to enter credit card info.

Keywords depend on the app - no site is going to give you words that relate to the app you developed, no site would know about the app.

You get keywords by thinking.
