01 / product line
Three apps. One promise.
From the first night feed to the weekly grocery run to Saturday karaoke — deliberately small tools that do one job brilliantly and connect only when you ask them to.
LittleLog
android · com.rango.baby_tracker
A calm, private baby tracker for feeds, sleep, medications and milestones. Everything stays on your phone — no account needed, with optional backup to your own Google Drive.

Melodi

Turn any living room into a karaoke night. One phone hosts and plays the songs; everyone else scans a QR code to queue their picks. Cast to a TV for the full stage effect.

02 / what we build
Mobile apps. Websites. End to end.
One person designing, building and maintaining every product — from Android apps on Google Play to the websites that back them.

Websites & web apps
Fast, modern sites and web apps — landing pages, product sites and the web experiences behind each app. Built lean, no bloat, quick to load on any device.
03 / how we build
Principles that don't bend.
Three rules govern every product — and none of them move for growth metrics.
/01
Private by design
Your data stays on your device, or is shared only with the people you invite. No tracking SDKs, no ads, no behavioral analytics — nothing collected, nothing sold.
/02
Calm by default
Each app does one job well and then gets out of the way. No engagement loops, no streaks, no notifications competing for your attention.
/03
Yours to keep
Export and back up your data anytime — including to your own cloud storage. If an app ever shuts down, your records leave with you.
04 / open a channel
One inbox, read by a human.
A bug report, a feature idea, a website you need built — every message gets a real reply from the person who writes the code.
