About Weissgerber
I'm Antonin Weissgerber, an independent developer building digital products that respect your privacy and your time.
Philosophy
Great software doesn't need to be complicated or invasive. Each product I ship solves one problem, no more and no less. Four ideas guide the work.
Privacy first
Your data is yours. I don't collect unnecessary analytics, track behavior across apps, or sync information to the cloud unless you explicitly choose to. Most products run entirely offline or with minimal network dependencies.
Simplicity over features
I resist adding every possible feature. Each product does one thing well rather than many things adequately, which keeps it fast, reliable, and easy to use.
Sustainable pricing
No dark patterns, no attention-hijacking notifications. Products are either free or offer a one-time purchase for lifetime access. A recurring subscription only appears when that's genuinely the better model.
Quality and craft
Each product is built solo, taking the time to get the details right: performance, accessibility, and a smooth, thoughtful experience.
Background
I've spent several years developing iOS apps and web tools across productivity, travel, fitness, and investment research. Each one reflects a real problem I or people I know have faced, along with a commitment to solving it without compromise.
Whether it's helping students plan their revision, letting travelers track expenses across currencies, giving lifters smarter training guidance, or helping investors research company moats, the goal is the same: tools that quietly improve daily life.
