To be truly productive, you have to start with a good night's sleep. Easier said than done, right? Well, the good news is there are plenty of sleep apps on the market that can help you monitor and improve your sleep--whether you want to get a full eight hours rest or just want to maximize nap time. 

So for you, busy entrepreneur, here are seven apps each with a unique approach to helping you catch some healthful zzz's.

JetLag Genie

For the traveling entrepreneur: After you submit your flight information and personal sleep pattern data to JetLag Genie, the iPhone sleep travel app formulates a plan to ward off the haze of jet lag. Personalized plans prepare you to shift your sleep schedule pre-departure, during the flight, and at your destination, so you can remain a step ahead of looming jet lag. JetLag Genie also includes a melatonin guide, so that you know when the naturally occurring compound, which regulates circadian rhythms needs a boost.

Pzizz

Have trouble falling asleep? Pzizz uses the combination of a calming voice and relaxing music to lull you to sleep, and offers sleep and power nap modules, the latter of which can be used for as little as 10 minutes. The app, available on iPhone and Android, also generates a new, unique soundscape every time you use it so that you won't get bored with a repetitive set of sounds.

Sleep Cycle

If you're getting enough sleep, but never feel rested, here's the problem: you're likely waking up from a deep sleep phase. Sleep Cycle is an app that uses the accelerometer in your iPhone to monitor movement and analyze sleep patters to determine when to wake you, the bio-alarm clock only nudging you to consciousness when you're in the lightest phase of sleep.

Relax Completely

There isn't, of course, always time to slip into eight hours of proper sleep. When all you have is a short time to take a break, Relax Completely offers a hypnosis session, on iPhone or Android, guided by one of the UK's leading hypnotherapists and trainers, Darren Marks.

Sleep Talk Recorder

Ever wondered what, or whether, you mumble during sleep? Sleep Talk Recorder, available for Android and iOS, can help you get to the bottom of your nocturnal musings, recording everything you say while you snooze. The app only records sounds, usually in short intervals, so there's no prolonged or blank recording. You can even go public with nighttime mumblings, sharing via Sleep Talk's main feed.

Jawbone Up

Want to get a sense of how sleep is effecting your overall health? Jawbone Up, a wristband that tracks your movement and sleep, keeps tabs on your light and deep sleep, waking moments, every movement, food intake, moods, and reminds you to get moving when you've been inactive for too long. It connects with a dashboard app on iPhone or Android to organize and evaluate your data. Jawbone Up can also link to other apps such as RunKeeper, MyFitnessPal, or MapMyFitness to evaluate your progress and devise a holistic plan to get healthy.  

SnoreLab

Snoring keeping you up? Using the microphone in your iPhone, SnoreLab monitors your nightly snores and measures their intensity. This means you can test the effectiveness of snoring remedies and measure the impact of outside factors, such as alcohol, on your snoring. The app, which can be paired with anti-snoring mouthpiece VitalSleep to advance the lower jaw and reduce obstruction of the airways, is said to be particularly beneficial to snorers who are overweight, experience pauses in breathing while sleeping, or have mild to moderate obstructive-sleep apnea.
