I design and ship my own products — iOS, Mac, and web.
From idea to App Store.

Problem

Standard heart-rate apps give you a number but no feedback in the moment — you see the value, but you can't feel it.

Solution

Heart rate and stress measurement with bio-acoustic feedback: the sound adapts to your rhythm and gently guides it back to a healthy range.

Problem

Manual food entry is the weakest link in every calorie tracker. Most people give up after two days.

Solution

Recognize the meal from a photo, estimate calories and macros, and keep a daily log. Minimum input, maximum result — tap the button, take a picture of the plate.

Problem

Subscriptions leak away in small amounts: $5 here, $9 there. A year later it adds up to a freelancer's monthly paycheck. Bank aggregators want way too many permissions for that.

Solution

A local subscription tracker: add them by hand or from email receipts, see monthly and yearly totals, and get reminders before each charge.

Problem

Keys end up in Notes, chat threads, and .env files. You never know if one still works. Rotating one means hunting for a provider dashboard. Moving a key from iPhone to Mac means forwarding or retyping it.

Solution

A local vault on iOS for any keys — grouped by provider, validation on the main APIs so dead keys surface fast. Each platform has a Dashboard link that opens in Safari: issue a new key in the browser, come back, save it in the vault. One account across devices — copy on iPhone, paste on Mac. Encrypted export/import; open source so you can verify keys never leave the device.

Problem

Most guitarists get stuck as beginners — not from a lack of ideas, but because arranging, bass, drums, and production are skills they never learn. The spark dies before the track exists. Drum machines and backing-track apps make you play to a loop, not with a band.

Solution

A native Mac recorder that writes the arrangement. Capture a riff through a guitar processor or interface, pick a style, and in about 90 seconds you get drums and bass that feel played. Audio Weight, Style Weight, and Weirdness keep the result on your idea instead of drifting. MIDI Learn for Record / Start / Stop, MIDI Clock for tempo — then jam and keep the take.
