Software studio from the Black Forest

Apps and games without accounts or data sales.

We are two people in St. Georgen, Germany, and build everything ourselves, from the first sketch to the store listing. Ourly is on Google Play since October 2026, Two Ways. One Us follows.

Ourly on an Android phone: the daily question “What is the bravest thing you have ever done?” with fields for your own answer and your partner’s. The app is shown in German.

What we are working on

Two apps for couples, both usable without an account. Neither is in the store yet. As soon as one is, the link will be here.

Ourly

  • No account, you connect with a couple code
  • Your content is stored in the EU (Belgium and the Netherlands)

Two Ways. One Us

30 levels on three maps and a new question every day. You both answer, then you see how well you know each other.

Two Ways. One Us: home screen with lives, points, journey progress, the Play and Connect partner buttons and the question of the day. German interface.
How we work

Our principles

Only what the product needs

No accounts where none are needed. We do not sell data, and Ourly and Two Ways. One Us contain no analytics tools.

No racing the clock

No question in Two Ways. One Us has a time limit. If you want to think it over, you can.

Done means done

We never show a feature that does not exist. A switch that does nothing is a broken promise.

Delete without detours

All data can be deleted right in the app, in the couple apps for both partners at once. No need to email us.

What is not entirely up to us

  • In the points shop, Ourly shows a Google AdMob ad if you ask for one. Google then processes the device’s advertising ID, but only with your consent.
  • Anonymous sign-in and push notifications run on Google services that are not limited to servers in the EU. Your content itself is stored in the EU.

The details are in the privacy policies for Ourly (German) and Two Ways. One Us.

Studio

Two people in the Black Forest

siinovation is the partnership of Branko Hrustic and Natalie Siino-Hrustic in St. Georgen, Germany. We build software we want to use ourselves. We started with an app for couples. What stayed is the aim to finish things properly. No investors, no growth targets: we decide by what makes the product better.
