Progress #4 MWC

Hello world,

Its been quite some time since I wrote my last post.


I’ve been busy working on CoShopping. I put out the iOS version on the appstore already and also Android betatest version. Currently both are finished only Android requires some more testing.

I am working on the backend for CoShopping to allow buying the discounts for the shops and create the easy way to import the discounts. It also mostly works except for the buying part and some security issues. I was able to import current discounts using the new backend already.

CoShopping has already some users but only a few (10 or so). I want it to become a online shop where a little local grocery stores  can introduce their discounts for a fair price to attract local customers. Usually people go to the big shopping centres to buy stuff which is overpriced and not as good quality to save time because they don’t want to search every little store as there is no discount list for them or they don’t have webpage.

MWC Barcelona

I’ve been to mobile world congress in Barcelona this year. I’ve got invited by GameLab Barcelona for free so I took some week off to visit. It was nice to change the locality. Barcelona is always full of people while here in Presov I barely see somebody in the street in the evening. Also the weather was sunny I spent some time on the beach and going through the city practicing my spanish skills while being pleasantly surprised I haven’t managed to forget everything already (I lived in Spain for 6 months before). I visited the 4YFN and MWC to get in touch how to projects are being developed now. It was first chance for me to see how they are getting funds from the Bussiness angels/Venture capitals because we have nothing like this in Slovakia. There are not meets and no investors easily accessible.

It was an eye opening event for me. People were starting bussinesses everywhere right left up down 🙂 with even simple ideas like some kind of vibrator, flats booking, homemade food market… Just every possible idea and mostly everything was working for them.

Also there was presentation from crowdcube platform where they shown us a company which got invested in a million pounds/hour for four hours straight and afterwards still going strong and getting more investments just from their crowd funding platform 🙂 Kind of money here we can imagine in our wildest dreams.


I took a part in the Ludum Dare 38 and after some initial struggle eventually created the entry. My game is about little child trying to find his parents in the house haunted by the ghost and is called Amadeus.

I wrote most of the details on the game page of LDJAM so I won’t repeat them here if you want go there to look on how the universe has worked it out for me this time.

Other games I am working on including Splice and DieLight in this order. Both are being rewritten to Monogame and Xamarin with Splice being the first. I will write on progress then.


This is another project I got inspiration for in Barcelona MWC. They have a networking app for conference and here we have conferences but no networking app. I started doing this for iOS and Android with a friend who was supposed to do the server backend because I don’t want to do everything in another project alone again – CoShopping is enough of that experience for me. However there are another caveats this time 🙂 My friend got a lot of work in his job and does not have time right now to work so the progress stopped after 100 hours put into that and having iOS app working. I guess this is how the small projects usually go… Hopefully we will continue in the beginning of the summer again.



Progress #3 -Student syndrome

Progress #3 -Student syndrome

Hi world,

there is Ludum dare event this weekend! Although from last report my body was kept to work, my mind already flew to the LDJAM 🙂 After the jam I hope I will have some new game to write about. But now let’s get back to the report.

6 hours a day experiment

Last week I started the experiment with a six days a week working for six hours a day I wrote about in the last progress. This is strict limit and there is no exception (no less, no more working hours per day). It is a short time-frame to make some definitive assumptions. Anyway I can write some experience.

I am working for the six hours straight without the youtube/chats/web. Towards the end I am feeling a sense of urgency knowing that after six hours I have to stop and the rest of the job has to be done next day. To finish the tasks in the six hours schedule I started to do more planning in the evening. Also I enjoy the work more because it takes only fixed amount of time and I feel happier if I can finish everything I set up for that day.

I assume that most of the productivity now comes from a strict deadline which makes me to experience a little student syndrome everyday 🙂


This weeks work was shorter. Once the temperatures here went way below zero, I had an unplanned trip to check my grandmother’s house to prevent it from freezing.

During the week I kept on working on feedback I received for CoShopping. At some point I got fed up with Xamarin’s tools so much that I rewrote part of the GUI to the code instead of using their UI designer. Also with the programmer’s rage in mind I wrote a very negative comment on reddit discussion summarising my current experience with Xamarin’s technology. It was done with a hope that it will prevent somebody from loosing so much valuable time. I will also write a blogpost about my experience with Xamarin with some advices how to overcome the obstacles and what to choose or avoid if Xamarin is chosen. I am not feeling like an expert in Xamarin but a lot of teams are in same position trying to deliver their multi-platform apps and may use some of these experiences.

Anyway against all the circumstances, the CoShopping is almost done and I need only a few more days to finish it and publish as a beta so testers can come up with new bugs 🙂

Currently I am not implementing any new feature and I am working more on the UI design stuff, like recomposing the page for adding products, unifying the fonts and colours, etc. Also I am testing everything to make sure there is not “WTF, this was working!” when I will enjoy the new feedback 🙂

After this beta the app should be ready for release. It will be the first app released by myself on the AppStore. I already worked on one iOS app and a few Windows phone/Android apps before which were published. But the CoShopping will be the first iOS app published by myself 🙂

Summarised, the plan for next week is to publish the beta and update the website because it contains old app’s photos. Also the website should no longer states the beta-test since it will be going out. Rather it should be some marketing website translated to Slovak and Czech languages for marketing people that will come across.

That’s all for now and I am off and getting ready for LDJAM finally 🙂


Porting and redesign of CoShopping

Hi guys,

winter is coming, my runing session are coming short (haven’t run for last two weeks) and I’m becoming a little bit lazy with blogging. I guess it is because currently I am writing the CoShopping ‘s iOS version for the third time.

First it was in swift, then ported to Xamarin.Forms. This seemed to be a good decision because backend part was supposed to be same for Android and iOS version and there should be only minor changes required in the frontend part between iOS and Android versions. It proved to be very wrong. Xamarin.Forms is not mature project, it is full of bugs with each new version breaking the previously working api and introducing new bugs. It breaks also such a simple things as menu will inevitable crash the app on iOS 10 while on iOS 9 it was happily working 🙂 If somebody out there is trying to find crossplatform option for development I have to say that Xamarin.Forms is waste of time and money. This is based on my experience. They have a lot of bugs and are very slow in resolving them.

Currently I am porting this to Xamarin.iOS. This seems to be working. I managed to save all the backend stuff while having to write completely new frontend staff. Hovewer when I had to do a rewrite I also done some redesign with the UI and introduced a multiple local lists feature. Main screen of the app now looks like this:


I also created new icon:


I hope I can finish everything this week and put out the final betatest version. Before christmass I want to put the app out for iOS and work on the Android version using Xamarin.Android.


I also have to write that I’m working on the game called Fobia. It is mix between tapan kaikki and commandos. Players are in the position of commandos trying to reach their objective while killing the enemy soldiers in the stealth or action way. It is top-down shooter which features cooperative multiplayer.

I will write a separate blog posts about this because it seems to be getting more updates than CoShopping.

Late beginning

Hi out there,

I want to introduce myself and this blog.

I am computer engineer who likes to create apps and games. I have a lot of ideas which I want to make work. Also I am interested in fitness so you may see some posts about my current diet(a big problem to do it right) and workouts.

Little bit of history

Few years ago I started a project called prunum with a friend but it didn’t work out very good. We made few apps. It took a lot of time and energy with little financial results, but it was very good learning experience. All this was done after school and work. Currently we were developing the app for shoppings which should be multiplatform Android/iOS and windows phone.  Hovewer i didn’t have much time and was quite exhausted from finishing the masters degree. After successfully finishing the school I decided that working in the job won’t bring my ideas come true so I took the courage and quit. Afterwards I required some time to get my things together inside my head. During that time my friend decided to not continue on this project anymore because of the lack of time and also he wants to try to work abroad.

What this is about

Now i am working on my own and this blog will be my company and something I can refer to later to remember how things were when I started.

I will write here progress on apps, games and some personal gym stuff and things that interested me.
