TruliVerse

First app created — BP-log

I recently had to deal with high blood pressure again, including some unpleasant symptoms. I was prescribed medication to help lower it. Since I already had a blood pressure monitor at home, I started measuring regularly and writing the values down — the classic way, on a sheet of paper.

Out of curiosity, I looked in the Google Play Store for apps to log my measurements digitally. I quickly realized that most blood pressure logging apps didn’t match what I was looking for:
- registration required
- ads
- too cluttered or overloaded with settings

So I thought — alright, I'll just build an app myself that fits my needs.
I built this primarily for my own use.

The goal was a simple and clear app without registration and without ads. All data stays on the device.

The app intentionally has only two main areas:
1. Data entry — current or past measurements can be saved
2. History — a graph at the top and a list of logged values below

The values can also be exported as CSV or PDF.

It was an exciting project and my first real app.
If you’d like, you can download the APK here:
GitHub

And if you find it useful, I’d really appreciate any support.

Reports, tests or experiences are very welcome and help me improve the app and discover possible issues.

First Sound Pack Released

Over the last few weeks I recorded, cut, and reviewed a collection of sounds. What started as simple recordings gradually turned into a small, focused martial arts impact sound pack.

The pack contains punches, kicks, and short combo recordings. All sounds are kept raw and dry, intended for sound designers who prefer to shape and layer sounds themselves. This is my first sound pack release, and it felt important to actually finish something instead of letting it stay on a hard drive.

The pack is available here:
- itch.io
- Gumroad

Both pages include an audio preview.

I plan to continue building small, focused sound packs and documenting the process along the way. I’m already working on the next one.

Field recording without field recording…

On December 20th, I was standing by the roadside in Kiel, waiting for the XMas Ride 2025. I was already running late and started to panic a little that I might have missed it.

When I arrived at the street where the motorcycles would pass by, there were still people around — mostly families with their kids.

I quickly crossed the street, found a spot, and started setting everything up: tripod, microphone mount, microphones, the F3, and the action cam. I heard people saying, “They’re coming.”

I got excited, turned on the action cam, waved to the riders. Everything sounded great through the headphones. The motorcycles, the sound of their engines. It was worth coming here. This is going to be a great recording, I thought —
and then it was over. About six minutes.

I stopped the recording on the action cam. When I reached for the F3 to stop the recording there as well, I realized that I hadn’t recorded anything at all.

I packed everything up, frustrated.

Then I heard a child say, “There are more coming.” Great… I thought.

I didn’t set everything up again. And for the rest of the day, my mood wasn’t great.

New toys, but this damn everyday life

Last week, the Zoom F3, two Rode NT5s, and the DJI Osmo Action 4 arrived.
First impression: Nice!

Whenever I get new gear, I feel like a curious child.
I want to go outside right away, record, try it out — and then I realize:
no tripod, no mount for the action cam, nothing for the F3.
So I had to order a few more things — again.

When everything finally arrived, I eagerly put it all together.
Everything fits! Nice!
And then suddenly shopping, household chores, and everyday life get in the way.

There are no recordings yet.
But something has already formed in my head that I want to share.

How I almost got lost in the clutches of a website builder

I thought to myself, “Hey, a website builder like this is definitely the fastest way to get my site online.” Well, I couldn't have been more wrong... After just a few minutes, I realized that it was more of a struggle than a build: Text sizes are fixed, layouts jump around, and there's no real freedom.

In the end, the solution was clear: back to the basics with HTML and CSS – it had been a long time since I had worked with them, but I was able to get back into it. And lo and behold: a part of TruliVerse was created.

Sometimes the truly creative universe needs truly free code.
