This keyboard app has many features which people may like a lot. The layout and design is also good.
But the main and central drawback of this app is that it only works with the smartphones which has a good processor and high ram.
If you have a smartphone with a normal processor and ram below 2 GB than this app is not for your phone. If you download it in devices with low ram then the keyboard keeps on lagging continuosly. And if your typing speed is good than the keyboard almost gets hanged.
So do not install it if you have a low end smartphone.
