This app meets my basic needs for SMS filtering but it could be better with at least two enhancements: 1, and the most important) change the useless hide button for spam to "NOT spam" and 2) allow the user to designate the SMS filter page as the opening one. As to #1, I get shipment tracking or appointment reminder texts which are going into spam and it's much too easy to hit delete all when they are buried in a long list of real spam. It needs to remember they are not spam the next time.

This might be the best thing ever but there are some functional issues. 1. Tiny text with no adjustability. 2. No way to mark numbers safe, that you allow. 3. Tapping send text just bumps unsent message to bottom. Have to hit send, twice. 4. Screen flickers when sending text. 5. Notifications for incoming are hit or miss. With the advent of sms spam at all time highs with no discernible app that blocks, there is a lot of money to be made in this space. Too bad TM missed the mark.
