Find a hall. Or fill yours.
Give the zip code you are looking in, the date, roughly how many guests and what the function is. Every hall enrolled in that zip code hears from you at once. Know the hall already? Name it or dial its number and it goes to them alone.
A name, a telephone number and a zip code. That is the whole setup. When somebody nearby is looking, their name and number arrive in your inbox and you call them back.
Nothing is booked or paid for in the app.
4RsInvst makes the introduction. You and the hall settle the date and the price on the phone, the way people always have — so there is no commission, because there is no transaction to take one from.
Free on both sides. Android.
