Tremendous Experience
Having switched over from OnePlus to iPhone, I felt a terrible lack of a study timer such as the ZenMode. Emphasis has the cleanest UI amongst all the timers available in the App Store, and it's easy to use, doesn't prompt the user to purchase such and such plans to gain further access to the tasks, and is customizable to one's needs. I recommend it to everyone who is looking for a timer that doesn't require an upkeep (like maintaining your plants or pets) and just allows one to focus on the task at hand by eliminating the app-related noise.
