A solo founder, five quiet apps, one bigger one.
Today is built by Anthony Eli Rasch, working as Sapplify — a one-person software studio that makes small, focused apps for the parts of life that are usually over-engineered.
Before Today there were six smaller apps — each of them doing one thing on purpose. sWeight for weight, sCycle for menstrual cycles, sMoment for moods and journaling, sLists for the things you have to remember, sBudget for money, sTrain for workouts. They are buy-once apps with no subscriptions, no analytics theatre, and no "engagement" tricks.
Today is what happens when you try to connect those five quiet apps into one thoughtful one. Weight is not just weight when it moves predictably around your cycle. Mood is not just mood when it correlates with what you ate. Food is not just calories when it's a paragraph you wrote because something felt off. The only way any of this gets useful is if the app can see across domains at the same time — and until fairly recently, that wasn't really possible.
Most health apps in 2026 are gold-rush single-domain products: a calorie counter here, a cycle tracker there, a meditation app over there, each one optimised for their own retention metric. Today is designed on the opposite principle. No streaks. No notifications. No daily targets. Short sessions, nothing pulling you back. If you want to be left alone for a week, it leaves you alone for a week.
The AI inside the app is deliberately unnamed and short-spoken. It replies in one to three sentences, never moralises food or weight, and never says "a lot of women" — it only speaks about the person in front of it. It runs on Anthropic's Claude API. Your data lives in Supabase (EU-hosted) and belongs to you — you can delete it at any time.
I'm not a doctor. Today is not a medical device and will never pretend to be one — see the health disclaimer for the full version of that sentence. What I am is a careful builder who has been watching people's relationships with tracking apps for a long time and has opinions about which of those relationships are quietly damaging them.
If any of this resonates — the pieces about noticing over optimising, or about why streaks break people, or about why the same weight on two different days can mean two very different things — join the beta. If you have questions, the contact form comes straight to me.
Writing.
Most of what I think about this space lives in the writing section. A few that might be worth your time:
Today is in private beta right now. One person, one email address, one app worth building carefully.
