The New Trello iOS App

After months of goofing off and stalling our project manager, we’ve finally released the new version of the Trello iOS app. If you’re using an iPhone, you can look forward to a fancy new zoom feature, a redesigned card view, realtime updates, and less crashing than ever before. I hope.

This is our biggest release since the iPad app, so I’m not about to type up everything we’ve done, but almost every aspect of the app has been improved in one way or another. Enhanced checklists, better notification handling, offline card create… don’t even get me started on the sidebar! Check it out in the App Store now, and watch the video above for a quick preview while the update downloads.

Available on the App Store

Create Cards via Email

Using email as a productivity tool quickly turns into a mess. Hunting down email threads, cc’ing the right people, gauging the importance of a message, tagging… It’s impossible to keep up. Trello is pretty easy, though. You can see where something is in the process and who’s working on it, all at a single glance. But for a long time, the only way to really get emails into Trello was to copy and paste them, a painfully slow and error-prone process. Our newest feature removes that hurdle. That’s right, you can now email cards to your Trello boards!

How It Works


We’ve done all the set up for you. Just open up one of your boards and open “Email Settings…” in the Settings section in the sidebar. Copy the email address, send an email, and watch the card show up on your board! The subject of the email will become the title and the body will become the description. Cards sent to the email address will be sent to the bottom of the first list by default, but if you want to change that, open “Email Settings…” and change the default from there. You’ll be able to change the list and position within the list. We‘ll also look for these…

  • Any @mentions of board members in the subject (or on their own line in the body) are stripped out and that person will be assigned to the card. If you include anyone’s email address in either the To or CC field of the email, that will also assign them to the card.
  • We will attach on any attachments you have to the card so that nothing gets lost.
  • For any hashtags we find, we look for any labels with either the number (1-6, based on keyboard shortcuts), color, or name of the label. If we find any of these hashtags in the subject, they will be stripped out and the label will be applied.

We recommend you add the email address to your contacts list with a useful name to make it easy to add more cards in the future. Click “Email me this address” in the “Email settings” pane to do that easily.


This has been one of our most-requested features for a while now and I am personally excited to see it released. There are thousands of ways to use email to board: hand out an address to RSVP to a party, keep track of job applicants, upload customer feedback, or add stuff to your regular ol’ to-do list… the list goes on.

Introducing Power-Ups: Calendar, Card Aging, and More

We get a lot of feature requests. A whole lot. Some of them are even pretty good. But there’s no way we can fit them all in Trello without ruining the simple, core experience we work really hard to maintain. That’s why we’re happy to announce the launch of power-ups.


Power-ups are board-level features that you can enable and disable to provide extra functionality. Power-ups will be disabled by default, keeping your experience as clean as possible. To see all available power-ups, click the button in the board menu sidebar. From there, you can enable or disable specific power-ups for the current board.

There are three power-ups available for launch: calendar, card aging, and voting.

powerups list


As a list-based task manager, Trello lends itself naturally to date-oriented tasks and projects. Trello has always included due dates, but the calendar power-up adds a full-fledged calendar view of your cards, as well an iCalendar feed.

Some things you can do with the calendar power-up:

  • Quickly switch between week and month modes for a more specific or a broader view of cards
  • Drag and drop cards between calendar days to quickly change their due date
  • Click to expand calendar days for a roomier display of cards
  • Export an iCalendar feed of cards with due dates to your favorite calendar client


Card Aging

Card aging helps you see cards on a board that haven’t been touched in a while. When enabled, cards will visibly age with inactivity. There are two modes: “Regular” and “Pirate”. In regular mode, cards become progressively more transparent and “fade out” the longer they remain untouched. In pirate mode, cards will tear, yellow, and crack like an old pirate map.



“Wait, voting? Doesn’t Trello already have that?” Yes. Voting can be an incredibly useful feature, but in the real world the majority of boards don’t use it. So to keep things simple, voting has been converted from a core feature into an optional power-up. Voting functionality and privacy settings are the same as before.

We hope you like them. Follow us on Twitter, Facebook, and Google+ and let us know what you think.

Webhooks Are Here!

We’re happy to announce the launch of webhooks in our developer API! Webhooks provide a way for apps to be notified when there is a change to a user’s board, card, list, or any other model. This is perfect for developers working on third party apps that need data to be in sync.

Why We Need ’em

There are a number of third party apps that either use Trello as their backend or have Trello integrated as part of a larger product. With our current API set up, third party apps need to constantly poll for updates in order to stay in sync, even if there isn’t anything new. For some third party apps, that’s a Trello request every few seconds per user they manage.


As you can imagine, this is super demanding on both Trello and the third-party app’s servers. With webhooks, we monitor specific models like cards and boards and only send an update to the user when somebody performs an action, like moving a card or adding a comment. There’s no needless polling and our servers can sleep a little more peacefully.


Get Started

If you want to play around with webhooks, we’ve got a basic how-to in our API documentation which you can read here. It’s not exactly “plug and play”, but we hope you find it useful once you set it up. Happy developing!

Got questions about webhooks? Let us know on the webhooks card on our Trello Development Board or ask away on Twitter.

Trello for Android Tablets is Coming – Beta Testers Needed!

Many of you have been clamoring for a tablet-optimized Trello Android app, and we’ve heard you! We’ve been working hard this summer on the app, and it’s almost ready for prime time. The new tablet app includes all the Trello power you expect, as well as some nice touches like real-time updates, drag to archive, a shiny new card view, and drag and drop for lists and cards.

But it’s not not quite ready for launch! Before we release it, we need beta testers to make sure it’s as awesome and bug-free as possible. We’re asking you — our faithful, good-looking Trello users with Android tablets — to beta test the app. As a beta tester, you’ll get to watch the app grow up as we deliver periodic updates. Feedback from our beta testers is critical, and we’d really appreciate the help.

Interested? Getting set up is easy:

  1. Join the Trello for Android Beta Community on Google+.
  2. Visit this link and click the “Become a Tester” button.
  3. Download via the link provided or auto-update to the beta version.


Warning: there will be bugs. When you find them, let us know on the Trello Android Beta board or by emailing Don’t have an Android device? Remember, we have apps for iPhone, iPad, and Windows 8 too!

Editor’s note: Fog Creek’s Summer 2013 Internship Class is codenamed Iguana, hence the curious iguanas in the photo. Our interns Bonnie Eisenman and Jonathan Balsano have been working on the app throughout the summer.
