The most helpful feature is that it allows me to find my lost phone at any time, even if I am not near wifi or mobile data coverage areas. It can be used as an alarm clock when you are away from your home/office with no access to internet for notifications etc., but also has many other features like calculator, games, weather forecast, stock market updates etc. You need to have good knowledge of English language in order to use this app properly. With all its advantages, there might be some minor issues regarding how easy one user interface could get confusing sometimes (especially new users). This helps me keep track of important things such as work meetings schedule, deadlines which would otherwise go unnoticed without having them saved somewhere online. I like that it's easy to use, has all of my contacts in one place so i can manage them easily! It is also great for keeping up with work emails etc., which makes me more efficient at getting things done. The interface could be made better by adding some features or making changes where necessary but overall this app works well enough as-is. We've been able to keep track of everyone we need (as far as contact information goes) without having several different applications open.
