It might be Halloween but the only thing that has us scared is the prospect of paying for new iPhone and iPad apps when you don’t have to. We’ve rounded up the six best premium iOS apps we could find that are on sale for free for a limited time, and you’ll find them all listed below. These deals could be done at any moment though, so definitely download them while you still can.

This post covers paid iPhone and iPad apps that have been made available for free for a limited time by their developers. BGR is not affiliated with any app developers. There is no way to tell how long they will be free. These sales could end an hour from now or a week from now — obviously, the only thing we can guarantee is that they were free at the time this post was written. If you click on a link and see a price listed next to an app instead of the word “get,” it is no longer free. The sale has ended. If you download the app anyway, you will be charged by Apple. Some apps may have additional features that require in-app purchases. Subscribe to our RSS feed or use that feed to create an email alert so you’ll be notified as soon as these posts are published and avoid missing any sales.

Air pollution can be a problem anywhere, not just in areas of high population or industry. That is why there are over 2,600 EPA air quality stations across North America. It is important for people everywhere to easily find and understand air pollution levels.

RunCadence Mobile

Normally $2.99.

RunCadence was developed by two physical therapists to help the running community apply step rate to running via real time step rate notification and metronome. RunCadence App accesses the HealthKit on your IOS device that you already use and enjoy.

Cadence refers to the number of steps per minute (spm), and is a simple metric to help runners reduce their step length to help reduce the shock of impact at landing. Over the past few years,studies have emerged that highligh the role of cadence to correct common running related injuries (RRIs). As little as a five percent increase in step rate, while keeping running velocity constant, has been shown to reduce shock absorption at the level of the knee by 20 percent. Additionally, increasing cadence by 10 percent above preferred leads to a wider step width and a more level foot placement, which can afford distinct benefits for runners regardless of foot strike pattern.

Start using RunCadence to get more in tune with your running. While no shortcuts or “hacks” to running exist, gait retraining using cadence is the next best thing.

We encourage runners to go through the one-minute baseline test under “TEST” to determine your unique cadence.Upon completion, you’ll receive cadence values of +2.5, +5%, +7.5%, and +10% above preferred, which are meaningful values based on scientific consensus. These values can then be used as targets during training.

Let us help you take the next step.
