The apps we lead with

Three that are live, private by design, and built to stay out of your way.

SoulSync

GPL-3.0

Live on Google Play

A mood tracker that stays on your phone.

A private, offline mood tracker. No account to create, no ads, no analytics, no data sent anywhere. Log how you feel, attach notes and photos, and let your own history show you the patterns. Open source, so the privacy claims are verifiable rather than a promise.

10-Point Mood Scale

Decimal precision if you want it, plus notes, photos, activities, and backdated entries.

Stats That Mean Something

Trend lines, mood heatmap calendar, best and toughest days of the week, and real activity correlation.

Insights in Plain Language

"You tend to feel best on Tuesdays." Your numbers, read back to you. No chart-squinting required.

Private by Architecture

Local SQLite database, JSON export and import, five themes. Your entries never leave the device.

Nudge

GPL-3.0

v1.9 • Google Play

Break the scroll. Take back your time.

A privacy-first, open-source app blocker for Android. Born from a disdain for subscription services that charge for what should be free, and a refusal to let infinite-scroll content steal your attention. Zero internet permission. All data stays on your device.

Delay to Open

Breathing exercises before opening distracting apps. The pause that breaks the habit loop.

Block Shorts & Reels

Block YouTube Shorts, Instagram Reels, and TikTok in-app. Use the app, skip the doom scroll.

Zero Tracking

No internet permission. No analytics. No accounts. Your data never leaves your phone.

Time Budgets

Per-app daily time limits, schedule-based rules, app groups, and grayscale mode.

Piano & Guitar Trainer

Free web app

Live in your browser

Learn piano and electric guitar, by ear, in your browser.

A practice companion that teaches piano and electric guitar from first principles. Every musical term is tappable and explained in plain language, lessons are ordered along a real prerequisite skill graph rather than a random list of drills, and the whole thing is built on motor-learning science, so practice actually sticks. Nothing to install: it runs entirely in the browser with real audio and notation, and your progress is saved on your device.

Two Instruments, One Path

A full piano curriculum and a 27-node electric-guitar track, both walked along a real prerequisite-checked skill graph.

Nothing Left Unexplained

Every note, chord, and bit of theory is a tappable term: what it is, what it sounds like, and why it matters, in plain language.

Built on Motor-Learning Science

Micro-rests between rep blocks, BPM laddering with a metronome, interleaving, and 1-3-7-14 day spaced review so skills become automatic.

Nothing to Install

Runs in any browser with real audio and sheet-music notation. Progress saves locally; sign in to sync it across devices.

Origo: Astrology & Tarot Companion

Live on Android

Your whole chart, held in mind.

Most astrology apps forget you the moment you close them. Origo is the opposite. Meet Vega — a companion who knows your full birth chart, reads tarot through your live transits, and remembers every conversation. The astronomy is exact; the meaning is yours.

✦

Your full chart, in context. Every reading is computed from your real natal chart, not guessed.

◈

Tarot through your transits. Cards read against the planets moving over your chart right now.

☽

Vega remembers everything. A companion who keeps the thread across every conversation.

⟡

Honest by design. One clear price, a real free trial, cancel in two taps. Never a funnel.

// About

Raedus Labs is an AI products studio and open-source workshop. We build tools that think with you and respect your attention.

We ship AI-native apps and open-source tools, and write about the engineering behind them — including Production AI Agents, our book on building autonomous systems. We believe the best tools are the ones that get out of your way, whether that's organizing your thoughts or blocking the apps that steal your focus.

Open by Default

We open-source what we can. Privacy tools should be auditable.

Ship Fast

Build the MVP, ship it, iterate from real feedback. No overthinking.

Privacy First

Your data is yours. No tracking, no selling, no exceptions.
