In one of my recent articles, I shared with you an experience I had involving the publication and testing of the mobile app Who’s Next?. Since the results of that experiment were very interesting, I decided to conduct another one, which I’m presenting to you today to spark a new discussion.

The context here is creating another app for fans of Role Playing Games, but this time I wanted to make a significant change in which phase of the work I shared. The first experiment provided very interesting results, but some of the new functions to be included required a significant amount of improvement work, because they affected many application entities. This made me think, “what if I were able to get feedback before beginning the implementation?”. That’s why this time I started sharing at a much earlier point in the work: the analysis.

Remember the User Profile, User Stories and Business Model documents that Andrea talked to you about a while ago? I created a summarized version in a single document, and I turned to the same Facebook group where I had shared Who’s Next? to launch a discussion about the analysis of an application rather than about an app that was already ready. The results were really interesting.

I got confirmation that the app was perceived as useful and interesting to most of the target users. Before beginning any development work.

The discussion led to some suggestions that completed my analysis. This was really interesting, because in this phase it’s much easier to take in comments, integrate new functions, or even discard those that don’t actually turn out to be that important. It was as if I was strengthened by the people who took part in the discussion, and I achieved results that my friends who helped me and I wouldn’t even have imagined.

Completing the analysis also led to a clearer picture of the effort required to create the app, and allowed us to take stock from the beginning of all the functions to be implemented. In recent weeks I’ve started the actual development, and as we’ve proceeded I’ve changed the initial structure of the project very little, moving very quickly toward the first version.

I had multiple people available to participate in the alpha testing, all users in the target, whose goal is to have a tool that truly helps them when they play. This is a powerful motivation, the best there is.

In the end, even the summary form of the analysis document proved to be important. In fact in the past, I had already had occasion to share the extended documents with friends, but there’s no avoiding it: a concise and effective form of communicating is necessary if you want truly useful feedback.

For my part, the social approach has been confirmed as a helpful tool to try. The important thing is to identify the correct group to share with. This may actually be the most difficult part, but if we start by identifying the target users and the interests they share, the nature of social media itself should come to our aid.

If you’d like to discuss this subject further, get in touch: I’d be happy to share the analysis document with you along with some thoughts on how it was created.


Today I’m writing to share an interesting experience I had with the publication and testing of a mobile app. It’s a utility for people who, like me, are passionate about Role Playing Games.

It all started when a friend asked me to create an Excel spreadsheet for him to simplify management of a rule, a task that usually forces the game coordinator to write over and over again on a sheet of paper that quickly becomes both illegible and inconvenient. As often happens with those of us in IT, I got a little carried away, and I made an app with Instant Developer Cloud that I called Who’s Next?.

For the analysis I took Andrea’s advice, creating three documents: the User Profile, the User Stories, and the Business Model. For the UI, I used the Ionic2 component to get a nice interface quickly, and I have to say I’m pleased with the result.

At that point, I had an app ready. I had a clear idea of the target it’s meant for, and it seemed like a bit of a waste not to keep going. I thought I’d launch an experiment and make it public to see what would happen.

I decided on a social approach, so I put a few posts on Facebook groups of target users in Italy, since initially the application was only in Italian. Users with common interests gather in groups on all social networks – it’s in the nature of these networks – and it wasn’t difficult to find an interesting one. I presented it as an idea, asking if people might give me feedback, suggestions, or even tell me if they didn’t consider the app necessary.

The result was very interesting.

Presenting it this way wasn’t viewed as an advertisement, and quite a few people downloaded it: about 120 in the first two days. The people who got involved proved to be much more interested in giving credence to a group post rather than an ad.

Reports on bugs were offered in a spirit of collaboration, and didn’t in fact lead people to uninstall. Instead, interest in the application was piqued, and people were inclined to wait for a new fixed version.

I got positive feedback that the app is useful for target users, something that was certainly not a given.

The many comments even contained suggestions for new features that my friends who helped me with the early tests and I hadn’t even thought of, and which actually turned out to be very important for players – “if it did this too, I’d definitely use it.”.

Now I’ve translated it into English, producing a multi-language version, and I intend to proceed the same way with it, potentially reaching 20,000 users around the world. Still free.

What do you think? Is this an approach we could attempt consistently? What pros and cons do you see in this dynamic?

And oh, if you’d like to take a look at the app, you’ll find it here.


Easter is nearly here, and as Andrea announced a few weeks ago, the new release Instant Developer Foundation 16.0 is ready for you.

We’ve introduced many new features and important improvements, and I have to say that I’m really pleased with the work done in this version.

Regarding the User Interface for apps made with Instant Developer Foundation, the two most significant implementations will make many of you happy. For starters, you can now vertically center the text in book boxes. We’ve also broadened the support for Bootstrap introduced last November, and in addition to implementing a number of improvements suggested by the community, we’ve also implemented the following functionalities:

  • managing fields outside the list;
  • integrated HTML editor;
  • full responsive in small devices.

Regarding the framework, the most important technical innovation is that it’s now possible to serialize sessions in Java. This particular functionality is useful when the server infrastructure is configured in balanced-load multi-node clusters. With this functionality the session can be moved from one server to another. What’s more, in simpler cases where there is only one server, the session remains active and functional even if Tomcat is restarted. Interesting feature, don’t you think?

For the IDE we’ve also listened to your requests, and implemented a number of improvements in the user interface of the IDE. Starting with version 16.0, you can:

  • see a preview of the Bootstrap grid to make it easier to design forms;
  • sort objects in a form by type;
  • run a simple text search text across the whole project.

Finally, regarding mobile development, we’ve updated the Android packages template from Eclipse to Android Studio, the most up-to-date solution, which I know interests many of you.

But these are just a few of the changes and improvements we’ve made. Details for each of them will be available soon in the version release notes.

I’m sure that this version will reassure anyone who wondered if Pro Gamma’s commitment to Foundation might have wavered. As you can see, that’s not the case, and in fact we’ve got big ideas moving forward in 2017.

Don’t stop reporting improvements you think will be important. You know by now that it’s vital feedback for us to be able to provide a continuously improving tool for implementing your business.

I look forward to your comments on Instant Developer Foundation 16.0.


In the user experience in web and mobile applications, drag&drop is used frequently to interact with a given object, to create relationships between one object and another, or to upload a file. Basically, drag&drop has become part of the user experience that we all expect.

That’s why recently Andrea suggested to me that we integrate this functionality into applications created with Instant Developer Cloud.

Today I’m presenting the two new components that resulted from these efforts: Interactable and Dropzone.

Interactable is based on InteractJs, a library that lets you make an object draggable or resizable, or transform it into a drop area. To use it, you need to put an Interactable object in the View and specify for which objects this functionality should be enabled. Make this selection using the DragAcceptedElements, DropAcceptedElements, and ResizeAcceptedElements properties. There is more information about how to set them in the contextual documentation.

Dropzone is based on DropzoneJs, a library that makes it easy to create a drop area onto which files to be loaded to the server can be dragged. To use it in applications, simply create a Dropzone object in the View and the application is ready to upload files. The Dropzone component can be customized: you can choose whether to accept only a certain file type, limit the number of files that can be loaded, customize the graphic appearance, etc.

To show you how intuitive interfaces created with these components are, we’ve prepared two examples for you.

To try out the drag&drop between objects, open the Interact example. The start menu offers three choices: Tree, Double List, and Calendar.

The Tree view shows how simple it is to use drag&drop to move tree elements from one node to another: just touch one and drag it to another node. Elements can be deleted by dragging them onto the recycle bin icon at the bottom of the page.

The Double List view instead shows how you can move an element between two different DataMaps simply by dragging it.

Finally, the Calendar view shows a simple planner in which events can be dragged from one day to the next inside a given week. Resizing an event changes its duration, as happens in the calendar applications we’ve become accustomed to.

To try uploading using drag&drop, open the Dropzone example and drag an image onto the special area: the upload will be completed and the image will be shown in preview. The files on the server are visible in the section below. The previews can be deleted without deleting the corresponding files.

In this example, the Dropzone accepts only image file types. If you try to drag other file types, like a PDF for example, it will not be uploaded.
