Instagram has updated their API requirements and terms of usage of their service. As we don’t know exactly if you app would be approved to form part of their new restrictive ecosystem and the new limitation would heavily damage the functionality of our app, we are stopping development of Analytics for Instagram. The app will be available in its current state until June, which is when the new limitations are applied to old apps.

We are sorry about the inconveniences and we hope that stuff like this won’t happen in the future.


Beautiful morning

Development, Photography, Random Stuff


Taken this morning… We also want to inform about our new app: Hipster Tools. Right now it’s in early development state. More an idea than an actual app, with only a few lines of code written.
But the idea is there and we are definitely working on it. We hope to release as soon as possible, but we don’t want to start with alpha or beta versions this time. This time we want to publish a finished product to our users, avoiding all the trouble, both for us and the users, unfinished versions cause.
Updates will follow on this blog!

Derfin MP3 Google Play termination

Development, Projects

Derfin MP3 Downloader was deleted from Google Play Store by the Google Team. The reason:

Violation of section 4.4 of the Developer Distribution Agreement which states that:

You agree that you will not engage in any activity with the Store, including the development or distribution of Products, that interferes with, disrupts, damages, or accesses in an unauthorized manner the devices, servers, networks, or other properties or services of any third party including, but not limited to, Android users, Google or any mobile network operator. You may not use customer information obtained from the Store to sell or distribute Products outside of the Store.”

We suppose that the underlined text is what removed Derfin from Play Store. Also, in the eMail, they link to the ToS of YouTube and the YouTube API ToS. Our App doesn’t use the YouTube API, so we ignored that, but reading the YouTube TOS we found:

“[…] Such Content may not be downloaded, copied, reproduced, distributed, transmitted, broadcast, displayed, sold, licensed, or otherwise exploited for any other purpose whatsoever without the prior written consent of YouTube or, where applicable, YouTube’s licensors. YouTube and its licensors reserve all rights not expressly granted in and to their Content.”

So we’re pretty sure that it wouldn’t make sense to insist in the fact that our app is actually just a framework for an online service which isn’t even operated by us.

Derfin MP3 Downloader will be discontinued. We will inform about new projects as soon as we decide to do next.

Even if there will only be a few updates from now, you can download/update Derfin MP3 from our Aptoide store.


We want to thank everyone who supported and continues supporting Derfin MP3. It was our first project and won’t be our last. Thank you all!


Android app on Aptoide

Derfin MP3 version


The newest version of Derfin MP3 Downloader will be available with the next few hours on Google Play.

This new version includes new icons for the app and a work around for a very common crash. The work around is fully functional but will only be present until version 2.0 on which we are already working.

The crash was caused an incorrect implantation of a system API and was triggered by clicking on the download notification if more than one download was running at the time. If only one download was running, the app worked as expected. Also, the crash only crashed the app but not the download manager, which means that downloads continued after the app crash.
