Five apps. Five jobs, done properly.

No bundles, no bloat. Each one exists because we wanted it ourselves and nothing else felt right.

01 · Documents

Foldyni

Your documents, calmly handled.

A private, encrypted drawer for the paperwork that actually matters — passports, insurance, IDs, health records. Scan with your phone, unlock with a glance, share through links that expire, and let Foldyni keep watch on renewal dates so you don't have to.

  • Encrypted by default. Every file sealed with its own key; nothing to configure, ever.
  • Scan anything. Auto-crop, straighten and read text right on the device — and personal details are redacted on your phone before anything reaches our servers.
  • Share Packs. Expiring, revocable links with QR codes — and you can see when they're opened.
  • Family Vault. One household, up to five people, each with the right level of access.
  • Renewals Inbox. A nudge before the passport, licence or policy lapses — not after.
  • A full PDF toolbox. Merge, split, compress, redact, watermark and sign without leaving the app.

02 · Your YouTube library

Crate

A command center for a library too big for YouTube.

Crate mirrors your entire YouTube library — every playlist, every saved video — into a private, lightning-fast index that you own. Search a hundred and fifty thousand videos in milliseconds, then rebuild your collections the way you always wished YouTube would let you.

  • Search everything at once. Full-text search across all your playlists, with facets for channel, tag and watch-state.
  • Virtual playlists. Sort, slice and save views freely — without touching the originals.
  • Duplicate detection. One entry per video, with every playlist it lives in.
  • Rot detection. Quietly flags what has gone private, deleted or blocked.
  • Your own layer. Tags, notes and watch-states that belong to you, not the algorithm.
  • Read-only by principle. Crate never writes to your YouTube account unless you explicitly ask it to.

03 · Remote input

Remotype

Your phone is the keyboard now.

Remotype turns the phone in your pocket into a real wireless keyboard and trackpad — free, forever, with nothing to install on Android. Then it keeps going: mirror and cast your computer to a TV, run it as a remote for an Android TV, dictate, fire macros, sync the clipboard. The keyboard and trackpad are free; the power tools are Premium.

  • Free forever: keyboard + trackpad. Native Bluetooth HID on Android — the computer needs no software, no drivers, no account.
  • Swipe typing, 50–60 wpm. Glide with the keyboard you already use; Remotype relays it key-perfect, with true modifier chords.
  • Trackpad mode. Two-finger scroll, pinch to zoom, right-click — your thumb becomes the mouse.
  • Cast & mirror. Premium. Send your computer's screen to a Chromecast, or mirror the desktop to your hand.
  • A remote for your TV. Premium. D-pad, power and a real keyboard for an Android / Google TV.
  • A deck of power tools. Premium. Dictation, macros, an air-mouse, clipboard sync, live vitals — plus Wi-Fi companions for iPhone.

04 · Nepali calendar

FamCal

Your bhittepatro, for the whole family.

A calm Nepali calendar — the digital बित्ते पात्रो. Bikram Sambat dates beside English, the day's panchang computed offline on your phone, festivals and holidays colour-coded, and the family tools that actually help: world clocks, reminders that follow the tithi, and a way to set up a parent's phone from across the world.

  • Two calendars at a glance. Bikram Sambat and English together, on a Today page and a month grid that read like the wall.
  • Panchang, computed offline. Tithi, nakshatra, sunrise/sunset and rahu kaal — on your device, for any year, no internet.
  • Festivals & holidays, colour-coded. Red for holidays, saffron for festivals, with a countdown to the next big one.
  • Reminders the Nepali way. Recur by tithi — every Ekadashi or Purnima, a shraddha by death-tithi, a birthday by its tithi.
  • Family, near & far. Set up a parent's phone from abroad, push them a world clock, set a reminder on their calendar, call in one tap.
  • Calm by design. Big type, an Elder Mode, a home-screen widget — and no ads, no tracking, ever.

05 · For new parents

Joju

One joyful app for the whole of the early years.

Joju turns raising a 0–5 year old into something joyful and shared — and quietly does the heavy lifting too. A whole world of bilingual learning games. Hundreds of illustrated bedtime stories and nursery rhymes you can actually hear. Streaks and daily play that keep little ones coming back. And the parent tools you reach for at 2am — vaccines, a symptom guide, safe medicine doses. All in English and नेपाली, all offline, with no ads and nothing tracking your family.

  • A whole learning world. 1,200+ bilingual flashcards across 68 topics, three quiz modes and real animal sounds — wrapped in streaks and rewards that keep little ones (and parents) coming back.
  • 800 stories, 100+ rhymes, all read aloud. Original illustrated stories for show-and-tell reading, plus classic nursery rhymes and Nepali folk बालगीत — with real recorded audio, so storytime works even when your voice is tired.
  • Watch them grow. Track developmental milestones, get age-based daily activities drawn from real child-development research, and keep a private photo journal of every first.
  • The 2am parenting toolkit. Smart vaccine reminders, an offline “when to worry” symptom guide, and a weight-based safe-dose calculator — the things every parent ends up googling.
  • Know where it all goes. A simple baby-expense tracker for diapers, formula and everything else, with monthly totals at a glance.
  • Made to share — and to trust. Turn a favourite photo into a beautiful keepsake card for Instagram or TikTok in seconds. Fully bilingual, fully offline, no ads, no tracking, ever.

The studio

Named for the keeper.

Custavia comes from custos — Latin for keeper, guardian, custodian. It isn't just a name; it's the job description. Everything we ship is built to hold something of yours, carefully.

Private by default

Encryption you never have to configure. Processing that stays on your device wherever it can. No analytics empire behind the curtain. Your data behaves like it's yours — because it is.

Small & sharp

Each app does one job, properly. We'd rather make a tool that feels obvious after a week than a platform that demands a tutorial.

Honestly engineered

We'd rather tell you exactly how something works than impress you with promises. Where there's a trade-off, you'll find it written down in the open — not in the fine print.

Be first in line.

The apps are in their final stretch. Write to us and we'll send you a single email when each one ships — no list, no spam, no follow-ups.
