When we get lost, nothing is more frustrating than when our Maps app crashes or refuses to fetch our location data. We rank that up there with the Gmail app failing to sync with Google's servers when we're waiting for an uber-important email to come in.

More Americans than ever own smartphones (46 percent, according to a recent Pew study, up 11 percent from last year), which means that on any given rainy day, a record number of individuals are sprinting angrily from the bus to the office door while cursing their weather apps for failing them.

Now, don't get us wrong. Apps have changed our lives. (Oh hai, Spotify! Hai, Chrome for mobile!) But a lot of our most frequently used apps are bigger disappointments than the Jawbone Up bracelet and the Microsoft Zune combined.

Whether you're an iPhone or Android user, check out the gallery (below) to see our least favorite, constantly crashing, glitch-prone apps or phone features that we use nearly every day. What are your least favorite apps? Is there an app you hoped would be revolutionary but only made you regret the day you downloaded it?

  • Facebook App

    iPhone and Android users can agree: <a href="https://www.facebook.com/mobile/" target="_hplink">Facebook's mobile app</a> is universally dysfunctional. We could go on and on about what irks us, but one of our biggest gripes has to be the push notifications. They're supposed to alert us to new messages or events, yet we frequently find we're being informed about old activity. Oh, and if you try to click through different features or menus too quickly, the app's bound to crash. Dislike.

  • Weather Channel App

    Should you bring your umbrella for today's commute? Your <a href="https://play.google.com/store/apps/details?id=com.weather.Weather" target="_hplink">Weather Channel App</a> might tell you -- if it feels like updating to today's date. Too often we've left our rainboots by the front door because our app was stuck on yesterday's forecast.

  • YouTube

    YouTube on the web? The best. <a href="https://play.google.com/store/apps/details?id=com.google.android.youtube&hl=en" target="_hplink">YouTube for mobile</a>? The pits: The search function is horrible, and too many videos don't play correctly (if at all) on both Android and iPhone devices. Plus, listening to music via YouTube means the app must remain open, so you can't jam out and text at the same time.

  • Siri

    Sure, she's entertaining enough. But does <a href="http://www.apple.com/iphone/features/siri.html" target="_hplink">Siri</a> really help with our daily lives? Not that much, no. We think the iPhone's voice-activated technology just isn't quite up to snuff yet. (We'll go right ahead and lump the Samsung Galaxy S III's <a href="http://www.samsung.com/global/galaxys3/feature.html#svoice" target="_hplink">S Voice</a> feature in here, too. It's awesome, but we hardly ever use it unless we're trying to show off.)

  • Gmail For iPhone

    We love our <a href="http://itunes.apple.com/us/app/gmail/id422689480?mt=8" target="_hplink">Gmail app</a>. We do. But those of us who use it on the iPhone are pretty sore that we still can't switch easily between two Gmail accounts. The Android users among us don't have to worry about this; but, just like the rest of us, they do find themselves cursing the app when it fails to sync with Google's servers (something that always seems to happen when we're expecting an important email).

  • Maps On iPhone

    Where did that little blue dot go?! When walking or driving with Apple's <a href="http://www.apple.com/iphone/built-in-apps/maps-compass.html" target="_hplink">built-in Maps app</a>, powered by Google Maps, the moving blue dot is supposed to be the user's location...but occasionally it's not. When service is sketchy, this GPS function might say you are blocks away from where you really are. Plus, the estimated time of arrival can be very optimistic, meaning iPhone users who think their journey will take 20 minutes are typically about 20 minutes late. Hopefully Apple can solve these issues when it <a href="http://www.huffingtonpost.com/2012/06/11/apple-debuts-maps-app_n_1587726.html" target="_hplink">rolls out its very own Maps app</a> with iOS 6 this fall.

  • Bump

    We think the <a href="http://itunes.apple.com/us/app/bump/id305479724?mt=8" target="_hplink">Bump app</a> (for both iPhone and Android) is actually pretty cool. Users are supposed to "bump" each other's phones to exchange information via mobile devices. Unfortunately, no one ever seems to have this app when you actually want to use it.

  • Reminders

    This iPhone feature doesn't do much. Supposedly it'll organize your life into uncomplicated to-do lists, but we typically find ourselves using <a href="http://www.apple.com/osx/apps/all.html#notes" target="_hplink">Notes</a> or <a href="http://www.apple.com/osx/apps/#calendar" target="_hplink">iCal</a> instead. Someone please remind us why we should use <a href="http://www.apple.com/iphone/built-in-apps/reminders.html" target="_hplink">Reminders</a>? Nope... you can't remember either.
