Indie Android studio
Dupercuper
Nine apps. One scroll of pinned chapters — iPhone previews auto-slide, stickers you can drag, stories that feel handmade.
Chapter 01 · Wellness
Kokoro Jar
Feelings deserve a place to land.
Not every day needs a productivity streak. Some days just need a soft place to rest.
Kokoro Jar started from a simple truth: mood apps often push you to perform wellness. We wanted the opposite — a jar you open, drop a feeling into, and close again.
Pick a sticker. Add a note if you want. Watch the month gather into glass. No feed. No judgment. No “don’t break the chain.”
Your journal never leaves the phone. Offline first. No account. Just you and the quiet habit of noticing.
- One-tap mood stickers
- Monthly jar + calendar view
- Gentle optional reminders
- 100% on-device storage

Chapter 02 · Arcade
Tiny Flap
Mastery hides inside a silly bird.
Tiny Flap looks cute on purpose — so failing feels fun, and one more run feels inevitable.
Tap to flap. Thread the gaps. Chase a score that barely makes sense until the rhythm clicks.
Twelve pixel birds wait behind milestones. A global board waits for the stubborn. One revive waits for the almost-perfect run.
We built it for the two-minute pocket of time between meetings — and for the hour you didn’t plan to spend.
- Instant one-thumb controls
- 12 unlockable pixel birds
- Global leaderboard
- One revive when it hurts

Chapter 03 · Safety
Emergency Call
When panic rises, UI should shrink.
Emergency Call removes searching, typing, and hesitation — so help is one intentional tap away.
Police. Ambulance. Fire. Your people. Nearby hospitals. Flashlight. SOS alarm. All sized for stressed fingers and low light.
Most of it works offline. Nothing asks you to create an account first. Contacts stay on the phone.
It’s a utility, not a hero fantasy — and never a replacement for official emergency services. Just a calmer path to them.
- One-tap emergency services
- Saved emergency contacts
- Share location fast
- SOS light + alarm tools

Chapter 04 · Productivity
Tidy
Clear list. Clearer head.
Tidy is a todo app that refuses to become project-management theater.
Add a task in seconds. Attach a reminder, priority, list, or repeat only when you need them — not before.
Upcoming view shows what’s coming without a calendar maze. Completing something feels like relief, not a scoreboard.
Soft color, space to breathe, light and dark modes. Built for everyday life: errands, work scraps, the thing you keep forgetting.
- Fast capture + smart reminders
- Lists with color & icons
- Upcoming timeline
- Repeats without complexity

Chapter 05 · Lifestyle
สุ่มหวยไทย
Luck should feel playful, not heavy.
Generate numbers, check draws, keep tickets together — then get on with your day.
Thai Lottery wraps the familiar draw ritual in motion and clarity: 6 digits, front/back triples, two-digit tails, multi-ticket checks.
Win moments get a little celebration. Between draws, light tips and auspicious reads keep the vibe warm — never predatory.
Entertainment first. Always. The app doesn’t sell tickets or promise outcomes. It just makes the ritual smoother.
- Animated number generation
- Latest + past draw checks
- Multi-ticket checking
- Save sets you care about

Chapter 06 · Lifestyle
สุ่มหวยลาว
Same craft. Different calendar.
สุ่มหวยลาว is the sibling of Thai Lottery — rebuilt around หวยลาวพัฒนา.
Randomize, check, browse history, save, share. One four-digit heart of the draw, with the rest derived the way players already understand.
Statistics are for curiosity, not prophecy. Past results never promise the next ticket.
A familiar interface for a different draw — so muscle memory travels with you across the border of ritual.
- Lao-number generator
- Results + past draws
- Browse-only statistics
- Save & share favorites

Chapter 07 · Puzzle · Soon
Pawzzle
Every board is solvable — by design.
Draw one continuous trail: hit every numbered paw in order, cover every cell once.
Pawzzle generates Hamiltonian routes, then remixes them so puzzles feel alive without becoming unfair.
It’s the kind of quiet focus you want on a train: haptic taps, clean paths, no account wall, fully offline.
Still warming up for store release — the logic is already stubbornly tested.
- Guaranteed-solvable levels
- Offline-first play
- Gesture-drawn trails
- Cozy, low-noise aesthetic

Chapter 08 · Fun · Soon
FateShake
Sometimes the answer should be a ritual.
FateShake turns indecision into a tiny performance — shake the phone, receive a nudge.
Built for group dinners, dare energy, and the moments when a coin flip needs better theater.
Lightweight, offline-friendly, intentionally silly. Not a life coach — a spark.
Coming soon. The shake is already impatient.
- Shake-to-decide interaction
- Instant playful answers
- Great for groups
- No account friction

Chapter 09 · Notes · Soon
Noto
Capture the thought before it escapes.
Noto is a quiet writing surface — fast in, easy to find, allergic to social noise.
We’re shaping a local-first notes app in the Dupercuper language: sharp contrast, calm motion, zero pressure to publish.
Lists, scraps, half-sentences — kept close, not harvested.
Still in the workshop. The blank page is waiting.
- Instant capture
- Local-first storage
- Distraction-light canvas
- Privacy-minded defaults

End of reel
Built small.
Shipped honestly.
Every app above has its own privacy notes. Read them, poke the demos, or email if something feels unclear — we write policies like product copy, not fine print fog.
