You're better off with a passphrase. They're easier to remember and much harder to crack based on characters.
For example, you could do something like (this isn't what I do, just an example, so don't even try to get into my account here) Thesearethedroidsyourelookingfor for this forum. Then, to make it more secure, you do the standard replace letters with numbers and symbols. Th3s3ar3th3dr0!dsy0u'relo0k!ngf0r. That's a 33 character password with one uppercase, numbers and symbols. Type something like that into any site that has a gauge to tell you how strong your password is and you'll win the game every time and it's still not hard to remember if you make the phrase go with the site or a memory of a time you visited that bank and saw something weird on the way there. Even if you don't use the numbers and symbols, it's still more secure and once someone figures out one of your passwords, they can't just brute-force attack your other accounts with variations on that one password.

I use mSecure password manager and have for years, but I'm gonna look into this. mSecure is very basic, but gets the job done. However, I tried LastPass for a while and it just seemed way too cumbersome for my liking (and the autofill never really worked right on my phone, so that feature was useless). I much prefer the idea of only having the info locally, whether it's encrypted or not. I mean, you're talking about ALL of your passwords for everything you do. These are the keys to your digital life.
The thing I do like about msecure is that it has syncing options though, so the passwords are still stored online. Export to sd card is good, but only if I can take that same card out of my current device and put it in my next device and still have my passwords. That's easy enough to test without losing them though.
So, after all my long rants, I'll check this one out, because it seems to be a middle ground between the simplicity of msecure and the convolutedness of LastPass. Most of the time I use my password manager, I'm on a computer and I pull my phone out to get my password, so I don't really even NEED autofill on my phone.
