Frequently asked, briefly answered.

The basics

What is Today?

A quiet AI health partner for iOS and Android that correlates your weight, cycle, and mood data to surface insights single-domain trackers miss. Built by Sapplify. Currently in private beta.

Who is Today for?

People who track their bodies and want thoughtful context rather than generic advice. Women in particular are underserved by health apps that ignore cycle physiology — Today reads weight and mood in cycle context.

How do I join the beta?

Sign up at the homepage with your email. When there's a build ready for you, you'll get two emails — a custom welcome with install links and a Supabase auth invite to set your password.

How much does Today cost?

Free during private beta. Post-beta it's planned as a modest annual subscription, closer to single-purpose indie apps than to coached programs.

What Today does differently

Does Today send notifications?

No. Today deliberately sends no notifications, keeps no streaks, and does not gamify behaviour. Sessions are short by design — open it, use it, put it away.

Does Today have streaks?

No. Streaks are a retention mechanic from games, not a behaviour-change mechanic from psychology — see our essay The problem with streaks for the long version.

Does Today count calories or macros?

No. Food is logged as a short sentence ("oatmeal and coffee") and used as context for correlations across your weight, cycle, and mood — never as a number to hit.

What does the AI in Today actually do?

It notices patterns across your logged data and surfaces them in one to three short sentences when you open the app or ask a question. It doesn't coach, doesn't moralise food, and doesn't give generic advice. The AI is unnamed, terse, and runs on Anthropic's Claude API.

Why doesn't the AI have a name or personality?

Because it's not a chatbot. The partner is deliberately unnamed, framed as something that notices — not an assistant, not a coach, not a companion. It replies briefly and then stops.

Compared to other apps

How is Today different from Cal AI, MyFitnessPal, or MacroFactor?

Those apps each focus on one domain (food / calories / macros). Today correlates across domains. A weight spike on cycle day 26 isn't "failure" to Today — it's normal late-luteal physiology. See /compare/ for detailed head-to-heads.

How is Today different from Flo or other period trackers?

Flo and most cycle trackers are single-domain apps with community and content layers. Today treats the cycle as context for the rest of your body — your weight and mood are first-class signals read through cycle phase. No ads, no feed, no notifications. (Full comparison.)

Is Today like Noom?

No. Noom is a coach-led weight-loss program with daily lessons, streaks, and a colour-coded food system. Today has no coach, no weight target, no lessons, and never categorises food — it correlates your own data rather than prescribing behaviour. (Full comparison.)

Privacy, platform, data

Is my data private?

Yes. Today has no ads and no third-party advertising trackers. Data is stored in Supabase (EU hosting available). You own your data and can delete it at any time. Sub-processors are listed in the privacy policy.

Can I export my data?

Yes. Your data is yours; export and deletion are supported. During the private beta the export format is JSON.

What AI model does Today use?

Anthropic's Claude, accessed via a server-side proxy so the API key is never present in the app binary.

Can I use Today on iPhone and Android?

Yes, both. Today is in private beta — TestFlight on iOS, internal-test track on Google Play.

Health, medical, miscellaneous

Does Today replace a doctor?

No. Today is not a medical device, not a diagnostic tool, and not a contraceptive. It's for self-understanding. See the health disclaimer.

Why does weight change with my cycle?

Progesterone-linked fluid retention in the late-luteal phase typically adds 1–3 kg in the 5–7 days before a period, then drops 1–3 days after bleeding starts. It's water, not fat. See Your scale is reading your hormones, not your progress for the full explanation.

Who built Today?

Anthony Eli Rasch, a solo founder working under Sapplify. Previously built six single-domain apps — sWeight, sCycle, sMoment, sLists, sBudget, sTrain — each solving one life-tracking domain. Today connects them. See About.
