No matter if you're spending Valentine's Day with a long-term lover or it's a first date, you're going to hope that the sparks are flying. Test to see how well your night is going with Lovetricity (Free, iPhone). Place your finger on the screen across from your partners and the app will tell you if your hearts beat in sync or if the date is flatlining.

There are few products that are more symbolic of Valentine's Day than those little chalky heart candies with disgustingly sweet phrases on them.

Flowers are a standard for any romantic endeavor, but you definitely don't want to forget the roses on the day of St. Valentine. The problem with flowers is if you buy them too early, they'll start to wilt; and if you buy them too late, you'll probably forget to take the price tag off. Guarantee fresh, tag-free flowers arrive right on time with Mobile Florist (Free, iPad).

Trying to capture all of the love and enchantment shared between two lovebirds on Valentine's can be difficult.

Picking out the perfect card can be a real struggle. If you find yourself standing at the card racks for hours trying to find the one with the saying that captures just how you feel, put down the envelope and pick up Red Stamp (Free, iPhone).

It's mid-afternoon on Valentine's Day and your date asks you where the two of you are going for dinner. You reply that it's a surprise, and it is. The problem is, it's a surprise to you too since you forgot to make reservations. See what local favorites are still serving and save yourself a seat with OpenTable (Free, Universal).

If you're currently planning to spend Valentine's Day alone, just know it doesn't have to be that way. You can spend it with some fine furry friends with Pet Shop Story: Valentine's Day (Free, Universal). Just don't do the part of the game where you can breed dogs. The mating process might be kind of depressing for you.

No Valentine's Day is complete without chocolates. Save your partner from having to pick through the box to find the ones with the good filling -- and yourself from having to eat all the leftover ones -- with Ghirardelli Chocolate Mobile (Free, iPhone). You can also use it to buy chocolate whenever. Chocolate tastes just as good on Valentine's Day as it does on a random Tuesday.
