Following a soft launch, The Boston Globe today is going public with its new app for tablets and phones, powered by Arc, The Washington Post’s content-management system. I’ve been playing with it since Tuesday, and I have a few very preliminary observations.

— It’s fast and attractive in a Post kind of way. The icon for the app is a white “B” on a black background, and the look and feel are similar to the Post’s black app. Stories load quickly, pictures are big and the type size can be easily adjusted.

— The organizational scheme is intuitive and makes sense. Across the top is a navigation bar that lets you choose from among Top Stories, Sports, Metro and the like. One of the choices is Marijuana, a hint of the paper’s expanded coverage of all things pot that is said to be in the works. Click on “Sections” at the bottom and you can drill down to more specific coverage. Again, this will be familiar to Post readers.

— Unlike virtually any news app I’ve ever used, you can’t swipe from one story to the next. Instead, you have to click the back arrow to return to whatever section you’re browsing. Stories load quickly enough that this amounts to a minor annoyance, not a major one. But it needs to be fixed.

— Stories appear in seemingly random order, even in the Top Stories section. As I scroll through the section right now, I see a few news stories followed by some sports, then back to news, then some more sports. The Top Stories sections of the best newspaper apps — those offered by the Post and The New York Times — are divided into sections and have a curated feel to them. The Globe needs to do better.

— As with the Post, there is no Today’s Paper listing of stories. That’s actually one of my favorite features of the Times’ app, since I might read a few stories on my way to work and then pick it up later during the day. A newspaper as a fixed record of the day’s most important events may seem old-school, but stories you might want to read tend to disappear from continuously updated apps. There’s a Today’s Paper listing at the Globe’s website, which works fine on a phone, even if it’s slow. I’d like to see that migrate to the app as well.

Based on first impressions, I’d give the Globe’s app a “B.” Given that the Globe’s owners, John and Linda Henry, have bet the farm on selling pricey digital subscriptions (currently just shy of 100,000), the tech side ought to keep working and get it into the “A” range. There’s a lot to like, a few things that need to be improved and one shortcoming — the inability to swipe from story to story — that is just plain unacceptable.

Update: A Facebook commenter says that you can swipe with the Android version. I’m an iOS user. But that suggests the problem won’t be too difficult to fix.
