apps I wish existed (so built myself)
things i built because i wanted them to exist. mostly local-first and privacy-minded, and all of them are live, so try any of them.
HealthySync
iOS app·healthysync.app ↗
- what it does
- syncs selected apple health data to your own backend instead of a third-party cloud. you pick the metrics, point it at your api, and the data stays under your control, with queued retries when the network drops.
- why i built it
- i wanted to analyze my health data with local LLMs but Apple doesn't provide an API for it, so i built this to expose my own health data to my local server.
Gold To Zcash
web, research library·goldtozcash.com ↗
- what it does
- a detailed history of money: how gold, fiat, bitcoin, and zcash each work, why money keeps changing, and what each system trades off, with sources.
- why i built it
- i'm deep into parallel economies, parallel societies, and sovereignty. while researching them, i ended up writing this detailed history of how money started, how it grew, and what form it might take next.
ZIPs Tools
web app·zips.tools ↗
- what it does
- a reader for zcash improvement proposals with better attribution. search zips by number, title, or owner, browse network upgrades, and map how proposals connect.
- why i built it
- the official ZIP pages weren't good enough for reading, and i kept copy-pasting links into AI just to understand them. so i built a better reader for them.
MacTicker
macOS app·macticker.app ↗
- what it does
- crypto prices in your mac menu bar. bitcoin, ethereum, and your watchlist one click away. native swiftui, no account, no api key.
- why i built it
- just for fun.
FinalNotes
web, daily comic·finalnotes.page ↗
- what it does
- a daily comic telling the story of someone whose work was shaped by mortality, illness, or hardship. source-backed biographies, no motivational slop.
- why i built it
- i wanted a small daily reminder that constraints and mortality often sharpen the work that matters, told through people who actually lived it.
InvoiceGen
macOS app + CLI·invoicegen.megabyte.sh ↗
- what it does
- a local-first invoicing workspace for macOS. manage clients, projects, and invoices and export print-ready pdfs, all stored on your mac with no accounts or servers. ships with a rust cli for scripting and automation.
- why i built it
- i wanted to use agents to create an invoicing workflow, so i built this CLI along with a macOS app for others to use.
StillReading
web app·stillreading.xyz ↗
- what it does
- a speed-reading tool for markdown. paste a doc and it streams one word at a time at an adjustable wpm, with play/pause and a running time-left readout.
- why i built it
- i read a lot of long-form markdown and wanted to get through it faster without losing focus. RSVP reading turns a wall of text into something i can actually pace.
