Simpl.day helps you
do what
matters today.

Simpl.day is a private, local-first app that holds a whole life in one place — tasks, notes, goals, life areas, people, mood, health logs, faith practice — and an AI Companion that can talk about all of it without your life leaving your phone. The one-line version I keep coming back to:

A trellis for a human life — it carries the small things, so you can go and live the large ones.

Everything is organized under six pillars of a flourishing life — Body, Stability, Belonging, Growth, Purpose, Transcendence — so the app has one lens for balance rather than a dozen disconnected lists. Your data lives on your device in app-private storage plus a backup file you own; no account and no cloud are required to use it. The name is the thesis: a simple day — the ordinary one, not the highlight reel — is the thing worth protecting.

The most consistent finding across decades of research on wellbeing is that the quality of your close relationships is the best predictor of health and happiness. Meanwhile, most of the software built for "wellness" runs on the attention economy's one move: the longer you stay on the screen, the better the company did. The harm is displacement — screens quietly crowding out sleep, focus, presence, and embodied human contact.

Simpl.day is built against that. Its governing image is the trellis: the app is not the plant, it is the support structure — and the better it works, the more it disappears beneath the growth. Its north-star metric is deliberately inverted:

Time-to-Human ÷ Time-on-Glass — real human contact created, divided by the screen time it cost. The dream is for that ratio to be enormous, and for you to need the app a little less every month.

A feature that increases screen time is treated as a regression here, even if people would enjoy it. Every path in the app is meant to end in a human, a place, or a piece of paper — never another screen. The app's proudest moments are the ones where it sends you off itself.

• The ordinary person reaching for more — not in crisis, just aware their days are being eaten; someone who has tried productivity and wellness apps and come away a little emptier. This is the heart of it.
• The person in a hard season — grief, burnout, recovery. They need a safety floor that doesn't depend on luck, one-tap reach to a real person, and a clean handoff to actual help — never a chatbot pretending to be that help.
• The seeker — someone after meaning, not just order: reflection, examen, a rule of life, faith practice woven into the same place their tasks live.
• The relationally hungry — people on the wrong side of the loneliness epidemic. The app's deepest work is not to be their company but to help them rebuild a real human network.
• The practitioner — therapists, spiritual directors, coaches who might one day use it alongside the people they serve. A first-class user in the long-term model.

The seeded life areas work for any believer or any secular user, and the app's faith surfaces stay quiet until you choose a tradition in Settings. The built-in traditions today are Catholic and a broader Christian framing; nothing fires unprompted before you've chosen.

One connected model, on your device

The spine is Pillar → Area: goals, tasks, notes, people, and logs all hang off life areas, so everything is connected in one graph instead of siloed features. All of it lives in on-device storage plus, on Android, a plain JSON backup file in your Documents folder that survives reinstalls — a file you can read, move, and own (iOS leans on iCloud backup).

An AI Companion that asks before it speaks to the internet

The Companion has selectable engines: a deterministic no-AI mode (rules and retrievers, no network), an offline on-device model, a hosted mode run by Simpl.day, or your own API key. A fresh install always starts in the no-AI mode — there is no silent online default. The first time you message the Companion on a build that offers the hosted mode, your message is held, unsent, until you choose. Every online call is logged in an on-device audit log — provider, model, token counts, never content — that you can read and clear in Settings.

Deterministic first, model second

Every turn is attempted deterministically before any model is invoked: crisis phrases match first and return real hotline information with no AI call at all; reads of your own data are answered by a keyword router that always wins over the model; and destructive operations cannot be triggered by AI output — nothing mutates until you tap a confirmation chip. Safety here is designed to be predictable, or it isn't safety.

Quiet by default

Almost all reminder rules ship off. Reminders sit in three channels so you can mute the app's suggestions while keeping what you asked for. And if you stop tapping a class of nudge for two weeks, the app sends one more and then goes quiet — silence is not consent.

More than a prototype, less than a launch. The codebase is roughly sixteen hundred Dart files with over ten thousand automated tests. The major shipped capabilities:

• The Companion — pluggable engines, ~33 deterministic read intents and ~20 confirm-gated write intents, a continuous conversation stream that files things into your real life areas with a correctable receipt, on-device dictation, and a crisis gate that runs before everything else.
• Tasks, areas, goals, notes — 24 task types, routines, dependencies, a day timeline; goals with why-chains and implementation intentions; notes with dictation, sketching, photos, on-device OCR, and semantic search via on-device embeddings.
• People — circles of intimacy, expected rhythms, conversation packs, accountability pacts, and a "night watch" for keeping quiet vigil with someone you trust.
• End-to-end encrypted collaboration — two phones can connect by QR or invite link and share a 1:1 chat, shared tasks, and a wake-together alarm; the server stores only ciphertext and membership, and cannot read any of it.
• Backups — a versioned on-device backup with full export/import, plus opt-in encrypted cloud backup where the file is encrypted on your device before it leaves and only you hold the recovery key.
• Assessments — chronotype, tempo, Big Five, values, strengths, love languages and more, composed into a relational pattern derived fresh on-device and shown with honest confidence bands, never fake-precise percentages.
• Faith — curated Scripture, Catechism, and Summa fact cards; all 150 psalm meditations with on-device narration; morning prayer; a daily verse. All human-curated — psalms and Scripture verbatim and citeable, some prayers written by the founder, never model-generated.
• Insights and Home — a bounded (never infinite) life mosaic, a north-star trend card, "one next thing", and a reflect-enough card that sends you off the app.
• An optional Android launcher — a still, monochrome home screen that takes two deliberate steps to enable and never seeds a feed.
• A public feature board — the app's one deliberately world-readable surface, where the most-voted requests steer the roadmap.

These are real and intentional caveats, not placeholders:

• Store launch. The app is in private beta; the Play Store path (closed testing with a required tester period, listing assets, policy declarations) is in progress. There is no public iOS release yet — the app builds and runs on iOS in development, but nothing you can install from the App Store or TestFlight; Android is the primary platform today.
• Broader shared accountability over the encrypted transport is built underneath but not fully surfaced; check-ins and digests still go out via WhatsApp, SMS, or email hand-off.
• "The loop" — a Context → Reflect → Plan → Act → Close cycle at every scale from a task to a life — is in development and ships dark until it is whole. The self-model's belief pipeline is similarly built but switched off.
• Platform skew. Phone-usage coaching, the session overlay, and the Documents backup are Android-only; iOS will lean on iCloud and local notifications.
• Accessibility — low-vision scaling and labels are done; full screen-reader coverage of charts and custom canvases is partial.
• Crisis phrase matching is English-only today, which blocks a non-English launch.
• The privacy policy has a known correction list pending — the code moved faster than the copy, and the copy is being brought back in line before wider release.
