"Mumbai Toilet Locator" was launched by municipal commissioner Ajoy Mehta.
The easy-to-use application is meant for android phones and can be downloaded from Google Play Store.
The civic body has connected over 800 pay-and-use toilets across the city on "Mumbai Toilet Locator" through GPS and that more locations would be added in near future, said a senior official from the department of Solid Waste Management.
However, an activist said the BMC should rather concentrate on cleaner and hygienic toilets.
