The digital platform at hopes to attract millions of renters by reducing (if not totally eliminating), arguments over rents and groceries.

"It would be very rare that there is no friction between housemates over unpaid or late rental payments and the sharing of bills when they co-habit," app developer John Bush, an accountant by profession, said.

"I have developed an effective solution to this problem -- making everyone's lives a lot easier," he added.

The website has a simple interface that allows users to note when the rent is due and who owes what. But more than that, it also provides an interface to an National Australia Bank account where tenants' shares are deducted from their accounts by direct debit or credit card, according to a pre-agreed split, then paid directly to rental agents, eliminating one of the most common causes of share-house angst.

Household bills and the names and phone numbers of preferred tradespeople (like locksmiths and electricians) can also be posted, and room-mates can even have virtual "house meetings" if their lives are never in sync for a proper sit-down.

As well as providing a safety net for forgetful housemates, the company has created two additional platforms for sole residents and commercial entities.
