Evaluation of the presentations and the course

First of all, we think that the presentations were given at a high level. Further on, all the questions were answered clear and honest.

Here are some remarks on the presentation of some teams:


We liked the flow diagram of different screens. This gave us immediately an overview of the possibilities of the app in just one slide.


If there was an award for the nicest logo, they would win it.


The application is mainly white. This is maybe boring, but also gives a clean look. They promoted their app via many ways, which is certainly interesting to gather more users.


We liked the fact that the failed Facebook log-in was turned into a well considered privacy issue. You have to sell your features right. This was the perfect example!

Chili Con Carne

The structure of the presentation was totally different from other groups. They discussed each problem separately and not each iteration. This was innovating. You might think it was disturbing, but this was certainly not the case.


To give feedback on the course, we would like to ‘tip’ the blog of Chi Con Carne: http://chiconcarne.wordpress.com/. Not because of laziness, but because of the very constructive and ‘to-the-point’ evaluation.

We agree on almost everything, except for the fact that you must know a website or mobile programming language. The three of us didn’t know anything about HTML5 or PHP at all at the beginning of the course.

Last, we also want to thank JeTS-CHI for winning their Highest chance-to-keep-using-the-app trophy.



Final presentation

Last Tuesday we presented the final design of Tip-It! In the end we got 40 users and this number kept on rising during the presentation. These 40 users accounted for over 200 tips.

So there were more tips than users. This was quite opposite to most groups. This is because our application focused the personal bond between friends. The consequence is that 2 users using the application together will boost our number of tips. If we check our database we see the typical 80-20 rule arising.

In general the reaction to our application was positive, people liked the plugin and the simplistic form of the website.  We also got a good remark about adding functionality to invite friends.

Iteration 4

Because in the previous iteration we noticed that it took a while for all the users to add a new friend, we changed this functionality and executed a new small test.

In the figure below, you can see we added three new tabs at the left side. One of them includes the ‘Add-friend’ functionality. In the previous version (unfortunately we didn’t find a screenshot) this functionality was included in just one friends-page instead of three.



Testing if the problems concerning the ‘Add friend’-functionality are solved. Namely the difficulty of finding how to add a friend.


Asking users to add a friend and record the number of clicks to measure the efficiency.


The fewer the number of clicks, the better users know how to add friends.

Who, What, Where, Time?

  • Who? 4 testpersons, 2 with good knowledge of computers, 2 less experienced users.
  • What? 1 specific task: add a friend starting from the ‘for you’-page.
  • Where? 200 A, Heverlee
  • Time? 2-3 minutes


n=4: needed 3 clicks to add a friend, this is the minimum number of clicks required to execute this tasks.


The problems with the ‘add-friend’ functionality are solved.


Official Release!

Tip-It! is online!



Go to http://tipit.cobemar.be and tip your friends an interesting site!



Tip-It! was already online since April 22th, but on May 7th, the official release was announced! You can see the evolution in the following figure of unique visitors per day generated by google analytics:


The two peaks match the two release dates. The first big one with the days after the unofficial release of Tip-It!, the second when we officially announced Tip-It! at Twitter and in the course.

The average number of visitors is also higher after the second release. We are now planning to ‘create’ a third peak by the help of Facebook and a special action. More on this later in the post! 🙂



Another remarkable thing that google analytics showed us was the high bounce percentage. This percentage gives the number of users that visit your site but leave the site without doing anything. At this moment this number is 44 percent. We try to decrease this percentage by adding a preview to the login-page of our site, as you can see below. This way people may be curious and take the effort to register and discover Tip-It! Thanks to google analytics we can compare the number today with a hopefully lower number in the future.



Via google analytics we want to investigate another issue. Do people tip sites mostly via the plug-in or via the site itself? To test this we created to separate submit pages where google analytics code was included. This way we can compare the how many times each submit page is executed and give an answer to our question. These results will be published later!


The last two weeks we made some final changes to our website and plugin. In the overview beneath you can see the evolution of our application. Each time three moments in the evolution are shown. First the paper prototype, in the middle the first digital prototype and as final the current look of the site:

For You Page


From You Page


Friends Page


New Tip Page






To make extra publicity for Tip-It! we are planning to make some small paper forms that can be tied to students bikes on the campus. We also started a Facebook and Twitter campagne. Like and follow us at http://www.facebook.com/tipitBelgium and https://twitter.com/Tipit_Belgium!
