A first good date is a combination of romantic luck and a little bit of careful planning. And just like everything else, there are a plethora of apps to help plan an unforgettable day or evening out together, whether it's your first time going out together or your 1000th. Here are a few apps to plan for smooth sailing instead of choppy waters...

iOS

Poynt
I find this local search app a great way for discovering events or venues in any area. For example, Poynt can be useful for finding movie theaters, complete with times and listings (you'll have to decide what is a "perfect date movie). Restaurant listings also offer in-depth details based on cuisine type; you can click to call or even book a reservation. Other search criteria include live music, live theater, gallery exhibitions and more. Free
Available for Android and Windows Phone 7

What's Next
Should you hit an unfortunate snag or need to kill time, What's Next will show a myriad of activities according to your current location. The customizable search feature caters to any situation or personality using precise filters such as popular, adventurous or 'off the beaten path.' Maybe you'll discover something new in your city that was under your nose the whole time, providing an answer to the awkward pause of "what shall we do next?" Free

Android

Foodspotting
Foodspotting is a different dining app from Yelp or Urbanspoon. Rather than finding restaurants based on reviews, hours or prices, Foodspotting sniffs out which establishments serve the dishes you want to have prepared for your special night out by recognizing your dining preferences. The visual presentation also aids in making a mutual decision when picking a place to eat becomes the question of the evening. Free
Available for iOS and Windows Phone 7

Goby
Need some inspiration for an original date? Goby has 350 different categories, which may lead to some amazingly inventive options close by. Whether you're searching for a little art and culture such as galleries/jazz shows, or something that requires a little more activity, like hiking or yoga, Goby lists them. Maybe even make an activity checklist for the day together! Free
Available for iOS

Windows Phone 7

OpenTable
The easiest way to avoid the awkward situation of waiting for a table forever on a first date is to make reservations in advance (duh!). And since OpenTable is connected to 15,000 restaurants, you can make one from your mobile device even while on your date. Browse through the large library of eateries and get free, instant confirmations. Frequent OpenTable users can collect dining rewards points which can be redeemed for dining cheques later (compatible with restaurants that stand under the same OpenTable banner.) Free
Available for iOS and Android

Next2Me+
Next2Me is practical for researching venues or activities close by and uses Google, Yahoo, Bing, Yelp, and Wikipedia to display accurate information. Search through 30 different keywords to zone in on a restaurant, theater, bar, or other such activity, and get directions or even a phone number to call to make reservations. $1.50
