Not accessible for password fields
Response from developer
AriesDesign, the keyboard is accessible in all IOS Apps and typing situations. What might have caused confusion is that if you switch to your system keyboard on an App then close and reopen the same App, the IOS will memories the last keyboard you used and will show it accordingly. This is a feature provided by the IOS for more efficient typing and it applies to all keyboards including the system keyboard itself. The password field is exclusive to the system keyboard and it returns back automatically to the current keyboard after password input.
Predictive removed
Response from developer
13sims2010, The previous keyboard versions didn't have predictive text so there was no way to turn it on as you mentioned. In the current update we added the predictive text and a pack of new awesome features and capabilities. Now you can enjoy having the number row alongside the prediction bar you have been looking for.
Took a gamble and lost
Interestingly it has nothing warning you about this that found.
Response from developer
One of Number Row Keyboard best qualities is that our policy clearly states that the keyboard doesn't collect any user information and all the keyboard data are LOCALLY stored on the device. The keyboard access is required by the IOS for all 3rd party keyboards to allow them to work with their full capabilities.
No spell check or word suggestions
