no support, site is in Japanese
While the free app seems at first sight one that would be useful, I found that I couldn't enter more than one site. After entering that single site, there doesn't appear to be any way to delete it, which comes to the third problem: if you change your site's admin password, there's no possible way of editing the site settings to update the password (did I mention that you can't delete the site?). Sure, you have a few days' worth of free use of a paid version to check if the paid version overcomes these deficiencies, but if there's no way to contact the dev AFTER YOU PAID, how can you resolve questions? [EDITED TO ADD] I popped for the one-month subscription, tried to edit my site due to admin p/w change, still had to create new account, still couldn't even delete the old unusable account. When creating a new account, this app wouldn't connect, told me to enter new endpoint. I have no clue as to what an endpoint is or how to find it. I cancelled the subscription. Also, with the subscription, at least you get access to the (useless) FAQ in English. There is also a "Contact" link that is dead (get a 404 error). 🤷🏻♂️ I strongly caution potential users against buying NOTE TO DEV: If you read this, please consider including a support link where users can contact you. An About and FAQ page in Japanese does no good for apps for sale on an English App Store.
