Why you make the app free in the first?! ### 1/5 — Stopped working *2019-09-10* Used to work but no longer does. Nothing is filtered to the tab, even unknown senders. ### 1/5 — 1 week trial, $8/year subscription *2019-01-04* Don’t know if it works or not. Its deceptive presentation in the App Store was enough reason to delete it immediately. ### 1/5 — Zorla para tahsil etmeye çalışması *2018-12-30, version 1.0.1* Yükledim bir kaç gün sonra sildim. Ancak deneme süresinde silmeme rağmen bir kaç günde bir para tahsil etmeye çalışmaktadır. Sakın yüklemeyin. ### 1/5 — Junk *2018-10-12* What’s “junk” is this app. Had it for a number of days now. It does nothing that can’t be done on the iPhone without it. Complete waste. I’d suggest RoboKiller over this all day long. ### 4/5 — Wish it had this.. *2018-09-28* This app does a great job filtering spam out of my main message section. I wish there was a way to completely block spam and ‘fake texts’ so it didn’t show up at all and sent an automatic ‘FAIL’ reply to the sender. I would buy that app! ### 1/5 — Paid monthly subscription *2018-05-15* Deleted instantly after seeing that the app wants you to pay a monthly subscription ### 5/5 — Works well filtering spam *2017-10-22* A friend told me about this app he was using to filter SMS marketing messages. I was getting several messages recently and this successfully filter most of them. There were a few that it missed but I contacted support and they said that the filter learns over time. I am super happy about this. Very quick response from the developers when I asked a question. Highly recommend it. ## Frequently asked questions about SMS Junk Filter ### Does SMS Junk Filter have ads? SMS Junk Filter does not contain advertisements.
