Interval training is defined as physical training that alternates between high-intensity work and periods of low-intensity work. For maximum effect the high-intensity workout is supposed to be near maximum exertion, while the low-intensity recovery period should be much toned down, even to the the point of complete rest. An example of interval training would alternating between sprinting for a full minute and light jogging for a minute. The idea behind interval training is to boost cardiovascular strength and aerobic capacity, making for stronger, faster, longer-lasting athletes.

You may not count yourself among the ranks of "athelete", but interval training can be of use to you as well. Thanks to SpeedyMarks' $0.99 Workout, you too can try out interval training. Workout is about as basic as an interval training app can be, and it doesn't need to be much more than what it is. Upon launch you're presented with three fields, a feedback selection, and a start button in a purple box. The fields let you set your work and relax period length (in seconds) as well as how many times you want the cycle to repeat. Feedback can sound a chime at each interval or be silent.

Hit the start button and the purple turns a pulsating red, ordering you to work. Your position in the current cycle is listed at the top of the red with a period countdown time below. A trio of Skip/Pause/Stop buttons at the bottom let you slow things down or speed them up, depending on how the workout's going. Once your work period is up, the block turns red and advises you to relax. Each switch between Work and Relax is accompanied by a high-pitched chime sure to cut through your labored breathing.

Workout is somewhat ambiguously named, being that it's an interval trainer and nothing more. But it does what it's supposed to do, and it does it with minimal fuss. Workout by SpeedyMarks is available now in the webOS App Catalog for $0.99 for all devices.

While every webOS device comes with some kind of speaker, the TouchPad is the only one whose speaker is adequate to fill a (smallish) room. On the phones, even the rear speaker struggles to put out enough volume to allow sharing of music or other audio in a space with moderate or higher background noise. Given that webOS phones all support both standard 3.5mm headphone/speaker jacks (the Veer admittedly needing an adapter) and Bluetooth speakers, there are numerous options for boosting the sound so others can enjoy it too. Unfortunately, most of those external speakers are far less portable than the phone itself. There are, though, some speakers that offer both powered amplification and portability. One of these is the Naztech N15 3.55 Mini Boom Speaker, which additionally operates as a standalone MP3/WMA player (it accepts microSD cards as removable storage, and has minimal controls for music playback and track navigation). While the Naztech's design and standalone player capabilities are pluses, however, its minimal amplification power makes it a poor choice for webOS devices.

Naztech has done a nice job with the design of the N15. It folds to the size and shape of a flattened golf ball, with a recess for storing the non-removable (and very short at 2-3 inches) 3.5mm audio cable. Along the periphery of the speaker are the standalone music player controls, a miniUSB (not microUSB, unfortunately, meaning it cannot share charger cables with a webOS device) port, and the microSD slot. The play/pause button doubles as the power button for the speaker, and a blue LED lights up when the unit is powered on. Note that although the track forward and reverse buttons double as volume controls for standalone play, they do not affect volume when the N15 is connected to an external sound source. According to Naztech, the N15 provides 2 watts of speaker output, and its 3.7 volt lithium ion battery charges (via a powered USB port or charger) in 4 hours. Naztech does not provide any play time details, and our testing did not extend to battery life.

While webOS devices do a great job supporting Bluetooth audio, there are times when you may want to go wired rather than wireless, especially if you're at all concerned about exposure to electromagnetic fields. The RF3 ENVi Natural Wood Stereo Earbuds with Earhooks, available from the webOS Nation Accessory Store (from which I received a complimentary pair for this review), have a few unique features that set them apart from other wired audio choices.

First, the basics: The ENVi earbuds do a decent job of noise isolation (not cancellation, though), with a variety of rubber tips to allow the best possible fit for different ear sizes. Although the buds themselves do not always feel solidly seated on their own, the unexpectedly comfortable wire earhooks (which can be turned and bent) help support the ENVi earbuds and keep them in place. For telephone calls, the ENVi offers an in-line microphone along one of the two earbud wires; it is usable but not ideal either in placement or quality. The microphone also doubles as a squeeze control for pausing/resuming music that works with webOS. The overall look is minimalist and industrial, combining angles and curves in a pleasing (to me, at least) way. As the ENVi is unpowered, it does not require charging or separate battery, nor does it offer any independent amplification of the sound it is carrying.

In a hurry and don't have time to read our entire review of the unreleased and unannounced HP TouchPad Go? That's fine, though we'd recommend that you find the time to read about this rare seven-inch webOS tablet that could have been. In the meantime, we went ahead and summed up the whole thing in under five minutes for you above in the webOS Nation video review of the TouchPad Go. You've got to have five minutes, right?
