Ryo Tsuzukihashi's profile on Product Hunt

About

Hi, I'm an iOS Engineer at ZOZO, Japan's largest online fashion retailer. My true passion lies in indie development. I love turning "what-if" ideas into reality and have shipped over 40 of my own apps, including a map to log travel memories. I'm obsessed with crafting simple and beautiful UIs, especially with SwiftUI. My goal is to enrich people's daily lives, even just a little, through the apps I build. Excited to connect with fellow makers here in the Product Hunt community!

EyeMole - Whack-a-mole where your stare is the hammer

EyeMole is whack-a-mole you play with your eyes. TrueDepth tracks your gaze — stare at a mole and the hammer drops. No tapping, no swiping. The twist: looking is both how you check a hole and how you hit it. A chick pops up sometimes, and staring a beat too long whacks it and costs time. • A gold mole reads your gaze and surfaces in your blind spot • 60-second rounds, combos and a Game Center leaderboard, all by gaze • Face data never leaves your device Free. Needs a Face ID iPhone or iPad.

Monivo - Your alarm becomes the voice of someone you love

Monivo replaces your alarm sound with a 15-second voice from someone you love. Your partner records "good morning" and that's what wakes you tomorrow. • Ask for the voice you need: "I can't be late tomorrow — be firm with me" • No friends here yet? Global Voices brings a stranger's greeting, matched by time of day • On iOS it's built on AlarmKit, so it rings even when the app is closed or on silent • Keep the voices you love and pin them to any alarm Free, on iOS and Android, in 12 languages.

nokki - One song a day becomes your diary

nokki turns the one song you had on repeat today into a diary entry. Pick a song from Apple Music, tap a mood, add a line if you feel like it. Thirty seconds. • Entries land on a calendar, stamped with the mood, so a month is one glance • Once a month a black cat reads your entries back to you (AI, on your own entries only) • Night Notes: a page nobody else can see, for nights you can't put into words • No public feed, no followers. Friends are mutual and invite-only Japanese only for now.
