Welcome to heidenreich.app.
Here you’ll find all the information and links to the apps I offer and distribute under my brand “heidenreich“. Take your time browsing around and have a look at the blog – you might find an interesting insight or a helpful idea waiting for you.
I’ve been working in IT and software development for about 30 years. What started as an interest has become my profession over the years – and above all, my passion. I enjoy tackling technical challenges, thinking things through and building solutions that truly work in everyday life.
For me, it’s not just about technology itself – it’s about simplicity. Software should support you, not slow you down. It should be clear, intuitive and free of unnecessary clutter. That’s exactly the mindset my applications are built on.
Many ideas come from my own daily life – from problems I wanted to solve myself or from things that bothered me about existing solutions. I build tools that I enjoy using myself – and that might help you make your everyday life a little easier too.
If you’re curious about how these solutions come to life, the thinking behind them or what I’m currently working on, feel free to stop by regularly.
heidenreich do
In my field, IT – especially as an all-rounder – tasks seem to come flying at you from every direction. Everyone wants something, everything is urgent … and unfortunately, you can’t do it all at once. You have to prioritise, or you’ll drown. When you’re deep into a technical topic, for example, you can’t work on the next big thing on the side and still deliver decent quality. Context switching costs time, energy and ultimately quality.
But this isn’t just an IT problem. It happens everywhere: Whether you’re a manager, an athlete, a student, a full-time or part-time parent – the list goes on. There are always things you need to remember and eventually get done. And it’s exactly this constant mental load that takes away your focus on what truly matters.
Free your mind from this burden. Offload what’s weighing on you. Make room for clear thoughts and real focus. Use heidenreich do – just do it.
There are countless task apps out there. I’ve tried many of them – and kept running into the same problems. Either they weren’t simple enough, not intuitive enough, or the hurdle of capturing everything was just too high. And even when everything was finally entered, the truly important things got lost in the clutter and were nearly impossible to find.
With heidenreich do, I’ve tried to tackle exactly this problem at its root. You can capture everything quickly and easily, and prioritise clearly. The important things always stay visible and in focus – without you having to search for them. At the same time, you’re intuitively supported in actually finishing tasks you’ve started, instead of endlessly putting them off.
In the end, it’s not about getting more done – but about doing the right things at the right time. Less to keep in your head, more to get done. That’s exactly what heidenreich do is here to help you with – simple, clear and without unnecessary clutter.

heidenreich log
heidenreich log is your flexible logbook – track everything that matters to you. Simple & private.
Mileage log, blood pressure, weight, calories or pet feeding – with heidenreich log you can create a personal logbook in seconds for anything you want to track regularly.
How it works
You create types with any fields you like – for example “Blood pressure” with Systolic, Diastolic and Pulse. Then you create a log with that type, give it a name and an image. From that point on, you can add new entries with a single tap. Date and time are set automatically, default values are suggested. Done.
What you can track with it
- Health: blood pressure, blood sugar, temperature, weight, medication, sleep, pain, calories
- Mobility: mileage log, fuel log, odometer readings
- Finances: expenses, fuel costs, tips
- Home & Garden: electricity/water meter, plant care
- Falconry: weight, rest day, feed, catch
- Pets: weight, feeding, vet visits
- Everyday life: mood, habits, working hours
- AI-powered food tracking (take a photo of your meal and let AI estimate its nutritional values).
- “What is this?” AI identifies your plants, helps you create the perfect travel journal, and much more.
- … or whatever you need – you define the fields yourself.
Your data belongs to you
All entries are stored locally on your device. No account, no registration, no cloud required. You can optionally set up a backup via Google Drive or iCloud – it’s your choice.
List view & chart
View your entries as a clear list or switch to the chart view to spot trends and patterns at a glance. Default values are displayed as reference lines.
Free with ads
One-time fee for permanently ad-free use – no subscription, no hidden costs.
Alternatively, you can use the Pro subscription for an ad-free experience, which also increases the AI limits for automatic analyses (e.g. in the food tracker or “What is this?”).
