I am using SMS organizer since a couple of months now. I love how it arranges sms in Personal, Transactions, and Promotions. I rarely need to goto Promotions tab, since it only contains all spam and junk SMS.
I also love the option to view only unread messages.
The best thing hands down is the copy OTP feature. Whenever an sms containing OTP arrives, it shows in big font right onto notification bar, and I can also tap a button to copy it to clipboard. Might have saved me tons of time, since these days you need OTP in LOTS of things.
