Small apps for money and thoughts.
I build apps I need every day myself. No account, no ads, and your data never ends up with me.

Finanzen
How much you can still spend this month, at a glance.
Set a monthly limit and when your month starts, for example payday. Finanzen then shows what is left until the end of the month and what that means per day.
- Apple Pay without typing. A shortcut brings your card payments into the app automatically. You only confirm the category.
- Subscriptions and fixed costs. They are booked on their due date. Price increases and cancellation deadlines are flagged.
- Goals and budgets. Savings goals with an expected date, budgets per category and a comparison with last month.
- On iPhone and Mac. Your data syncs through your iCloud. On the Mac with a sidebar and a transactions table, protected with Face ID or Touch ID.

Tagebuch
A journal you finish in two minutes.
Mood, energy, sleep and a few sentences about the day. Over time these short entries turn into a history that shows patterns everyday life hides.
- Your history. Mood, sleep and energy from two weeks up to all time, with averages and streaks.
- A report to take with you. A PDF for any period you choose, for example for your therapist or doctor.
- Values from Health. Sleep, resting heart rate and steps from the Health app if you want. Lock with Face ID or Touch ID.

Your data stays with you.
None of the apps has an account or a server of mine behind it. What you enter stays on your device.
No account
Download, open, start. No sign-in and no password to lose.
No ads, no tracking
No analytics services and no third-party libraries reading along.
Your iCloud, not mine
If you want, the apps sync through your private iCloud. I have no access to it.
