Teo Jun Sheng Pierre
Maker of CashJot
I'm Pierre, and I make CashJot, a manual expense tracker for iPhone. It's designed around the way I've tracked my own spending for the past three years: an amount and a tag at the counter, totals on a widget.
I live in Singapore, where cash and QR payments are part of every day. There are bank-syncing apps here, but most rely on screen scraping, so I wouldn't use them. I'd track by hand either way.
