Kinomap Trainer is a fitness app that offers synchronised video playback, enabling users to train at home or in the gym against pre-recorded, GPS-located outdoor routes. With the addition of sensors (speed & cadence) and an ANT+ receiver, users can sync the video footage to their own workout and measure their progress. Through wireless data transfer, the smartphone or tablet receives the rhythm, speed and stride power being applied and compares it to the video, with a map displaying a moving icon that shows the user’s position in either a terrain or satellite view.

Additionally, a multiplayer mode allows users to train with up to four friends, each with their own avatar on the map and voice chat to allow full interaction.

The ever-expanding selection of cycling, running and rowing routes submitted by Kinomap Trainer’s growing community gives any fitness fan the opportunity to see how they would fare on some of the most well-known and challenging routes from around the globe, including a bike ride through the Arizona desert, rowing past the Eiffel Tower or a sightseeing tour around Disneyland. You can find the Kinomap Trainer app on Apple’s iTunes store.

One such app is Bike Doctor, which according to an article over at pcworld.com helps cycle owners do their own repairs and maintenance. Tapping on the ‘Bike’ button in the Bike Doctor app – which has already been downloaded more than 6,700 times – will bring up an image of a bicycle. Tapping on the part of the bike they are having problems with will then display a list of repairs.

The app will even tell you how to clean your bike correctly without damaging it. The Bike Doctor app currently features 24 highly-detailed bike repair tutorials, with more coming at a later stage. Another similar app is Bike Repair, which comes with 48 detailed photo repair guides and explanations for 66 bicycle problems. A point worth noting is that Bike Repair also costs less than the Bike Doctor app.
