Although it will display the timer in landscape mode, you cant start or pause it. Instead, you must return the phone to portrait view. Nor will it display properly when you flip the phone upside down in portrait view. Both of those orientation issues are a bummer since the charging cable plugs into the bottom of the phone, preventing the phone from being positioned on a stand while plugged in and in operation. So close to perfection, but.... Its the easily resolved, yet missing features that earn this app a low rating.
