TimeSnapper is a joint venture between two people, Atli Björgvin Oddsson and Leon Bambrick.
Iceland and Australia are on opposite sides of the world.
When it's summer in Australia, it's winter in Iceland.
When it's nighttime in Australia, it's daytime in Iceland.
Leon dreamed up the idea, and wrote about it on his weblog.
Atli read the weblog and liked the idea. He wrote a simple version of TimeSnapper and emailed it to Leon.
Leon liked what he saw, so they worked together on a more complete version, and they entered it in a software developer's competition.
They won the competition and decided to go into business together, making a professional version of TimeSnapper.
Despite the distance, they worked closely together carefully crafting every feature of TimeSnapper, and ironing out every wrinkle they could find.
They launched it to a small team of dedicated Beta testers, who gave it a thorough review, asking them to fix and improve many things.
TimeSnapper has gone on to move through many versions and to sell many copies. People use it for things that the product's creators never dreamed.
Apart from helping with timesheets, it is used as a productivity tool, as a testing tool, as a stock tracker, as a factory monitor, as a monitor to help combat sleep apnea(!), and as a weather tracker for remote airlines(!).
