Shinkansen – Check Shinkansen seat availability

While spending a lot of time in Tokyo I built a small tool to help me check seat availability on Shinkansen trains. During one trip to Japan I bought a 2 week rail pass and spent 2 weeks traveling all around Japan. I wanted a simple, quick, easy to use that let me regularly check seat availability on Shinkansen trains so that I could plan my (mostly last-minute) travel. JR offer their own tool (previously only in Japanese, but now available in English as well) called JR Cyber Station. My tool just makes it a little easier to refresh my past searches.

Paperworks – Save all your receipts with one click

All your receipts, invoices, and payments in one place. It was my first project built as a One Week Build and posted it on Product Hunt where it became the #1 Product of the Day. Unfortunately the project is currently not accepting new users/customers due to changes that Google have imposed on API access to Gmail, which currently requires spending $15,000 to $75,000 for a security assessment.

Hyperbnb – Supercharge your Airbnb searches

Hyperbnb is a supercharged search for Airbnb listings. Features include more filters, sorting by reviews/rating, a computed “score”, and up to 300 listings at once. This project was also posted on Product Hunt and I also posted a One Week Build write up. Unfortunately the Airbnb endpoint I was using stopped working after a couple of years, so the app is currently suspended.

Glance – Your metrics, in one place

Glance started out as an idea to create a unified “company dashboard”, including various metrics such as Google Analytics, Social Media, and Stripe. Eventually we also developed a Slack bot (glancebot) that would integrate with your workspace to provide real-time metrics. After quite a bit of effort we eventually decided to shelf the project, but later ended up selling it to a new owner.

BrowserFrame – Wrap screenshots in browser frames

The easiest way to wrap screenshots in browser frames. Supports multiple browsers, operating systems, and themes. It was my second One Week Build also shared on Product Hunt where it became the #3 Product of the Day. I use it myself all the time (even here to generate the project screenshots), and it gets a pretty decent amount of traffic.
