I picked two bullish stocks and two bearish stocks with 14 days average hold time. I then checked the results after 14 days. Only one signal showed a profit of about 2%. One had a lost of 3.5% and the other two showed small losses under 1%. Total portfolio lost was about 47%.

There is simply no way any of these apps can guarantee any kind of consistent positive returns. There are too many market variables they cannot account for. It's the same for any of the technical analysis indictors or combination of them.
