Well the app will solve all your problems.
Unless you want to see what shops are in your area. You MUST read about EACH AND EVERY kind of project they offer and ACCEPT OR DECLINE each and every one, or you will not be able to see ANY of the shops available in your area, even the ones for projects you already ACCEPTED.
Or, if you want to do a gas shop that pays "$12.00!!!!!". There is no way to see which time of day (morning or evening) a given shop is for before (or after) you accept it,
You can fill out the questionnaire, but you can only enter answers in the order they insist on.
