The app used to work fine, but now it takes 1-2 minutes to load anything. I can't access the app anymore because it requires me to set Robo Killer as my text messaging app, which I don't want to do. There's no way around it - the app just keeps switching between two pages, trying to force me to set it as the default messaging app. The app is now useless!

Good app, nonexistent customer service. Their free basic plan works better than the Premium plan I paid for. It won't even get through setup, and there is no response from "Customer Service" after a week of submitting contact requests and emails. Get the free trial, then save your $ and move on to an app that actually has people who will assist with their product. MOVING ON (after getting scammed again!) Does anyone/company have integrity anymore??

Still NOTHING! It's been weeks! The app still does NOT WORK! I still get a few spam calls and I still cannot use the app! I have removed the app and reinstalled it three times. No word from the developers! Spam calls are blocked but the app freezes up. I can't block specific numbers etc because the app just keeps asking me to make it the default messaging app. Very frustrating to pay so much for a buggy app
