Dear Mr Jump fans,

Two weeks ago, we received thousands of tweets for our contest. We would like to thank you all for your love messages.

It's time to start a new contest! This time, you will have to tweet a short video about Mr Jump with the hashtag #MrJumpVideoContest before midnight on Monday 25th. The video duration must be less than 10 seconds. To record the video, you can use Twitter, Vine, Instagram or any equivalent app.

It can be anything related to Mr Jump: the reaction of your sister failing at Mr Jump, a stop motion animation, a funny cosplay, anything. Be creative!

Mr Jump is a platformer featuring 24 handmade levels. As the game is extremely difficult, you can imagine how hard it was for us to design its levels. We had to try every part and every trap many, many times. Designing a level is an iterative process, with the constant need to go back and forth from the level editor to the game.

That is why our level editor is an iOS app. This way, we can edit a level and directly try it out on a real device. As you can see in the video below, the app is not for public release because it is not really user-friendly. But it is really useful! The essential feature is the ability to start to play in a level from anywhere :)

Hello Mr Jump fans!

Wouldn't it be great if you could win a beautiful 3D printed Mr Jump?

We are launching a contest on Twitter: all you have to do is to tweet why you love Mr Jump before midnight on Sunday 10th. Don't forget to include the hashtag #MrJumpContest.

After months of hard work, we finally released our new game. PILE is a huge update of a little game we launched in 2012.

At 1Button, we were very fond of flat design before it was cool! Therefore, our apps already worked well on iOS 7 without any change. That said, they need to be updated anyway to add the new features of iOS 7, such as the translucent keyboard.

And today we begin with Mr Mood, +1 and Task! There is also a little surprise in the latter: we have added 5 new "Plastic" themes to match with your iPhone 5c. There is one new theme for each of them: White, Pink, Yellow, Blue and Green.

We have recently came across a funny little app on the App Store called Miss Diary. The concept of Miss Diary is quite simple: you record your mood every day and, after a while, you will be able see if you have a happy life. Yes, it is the exact same concept as Mr Mood :)

After Task was released, in June 2012, several blogs compared it with Clear, released a few weeks before. Indeed, we thought that Clear's gestures would become common in the future so we decided to use them in Task. And we were right, just like the well-known Pull-to-Refresh — introduced by Tweetie — these gestures are now a part of the interaction language of iOS. It is important to understand that Task is more a calendar app than a to-do list app. Besides, with Task, we have introduced many innovative features in order to rethink the calendar on mobile devices. And we have improved these features with Task 2. This major update is the opportunity for us to emphasize our contribution.

Before Task, we already had a little experience of iCloud: our games, SEQ and ON/OFF, use it to sync levels solved by players between their devices. Of course, with Task we had to sync tasks which is a much more complicated problem.

Task was initially designed to be an iPhone app. We see it as a little notebook that you always have with you. This is the reason why we chose not to make it universal: the iPhone and iPod were the only devices that you could truly carry everywhere as Task is supposed to be. But when Apple released the iPad mini, a few months ago, we were forced to change our minds! The iPad mini is small enough to be carried in a bag or even a pocket, so, being able to use Task on an iPad was no longer a nonsense. We had to make Task universal!

The GIF format is now public domain. As we were (and still are) in love with animated GIFs (we made a few ones with MS Paint ten years ago), we have always been wanting to use this format on the iPhone.
