The Newton app is a quality (if pricey) email client that offers simplicity on the surface and intelligence underneath, but it has at least one glaring flaw: that design philosophy doesn't carry over when you need to check your schedule. The Android app had a calendar feature, but it was bolted on. You might not have to make that trade-off for much longer. The developer has introduced a separate Newton Calendar app for iOS, and it continues that less-is-more strategy while adding some thoughtful touches. Most notably, you don't have to wade through the usual forms to add an event -- you tap the date, type in the time and title and you're set.
