This App let's you race against the virtual runner. You can set the virtual runner's pace from 5'30 to 4'00 min/km by pressing a lap button. Each button press equals to 10 seconds faster pace. The App shows you the opponent's pace for the first 100 m. "530" refers to "5'30 min/km" and "400" to "4'00 min/km". When the distance 0,1 km is reached, the Racer shows you the distance difference to the opponent. For example "10 m" means that the virtual runner is 10 meters behind you and "-15 m" means that you are 15 meters behind the virtual runner.

App shows your position compared to virtual racer as meters. Default speed is 5 min / km (3.333 m / sek). Modify this value to suit your racer speed.

Shows you the estimated Finish Time based on distance left and you average speed from previous 30 seconds.

This App shows the estimated Finish Time for 42.2 km race. Formula is below. In practice it means that in the beginning of the race the estimation is mostly dependent on average speed and in the later phase shifts to recent pace. This gives you stable and yet resposive feedback. forecastSpeed = (SUUNTO_SPEED_AVG[30] * progress) + (SUUNTO_AVG_SPD * left) If you run a longer route than the race distance is then the App begins to show duration instead of estimate.

"R8club" is a virtual caddie. It's not only suggesting the right club for the given distance but calculates the penultimate shot so that you can use your favorite wedge for approaching the green! Feel free to change the distances/ clubs to suit your game. Check also APPS: Bogeyman and Distance to Hole

This App is calculating the net benefit of the exercise in kcal. It's using the Revised Harris-Benedict-Equation for calculating the amount of energy expended at rest. The app subtracts this basal metabolic rate from the total kcal and shows you the net benefit of your exercise. Unfortunately, it's not possible to use height as variable. Thus Formula uses constant height of 180cm. This should be close enough for most of us, including myself (188cm).

This forecast is responsive to speed changes during the race. There are clear benefits for using current lap pace based forecast for finish time. E.g. first minutes are often slower, because of traffic, and thus average speed is clearly behind target in early race. Don't panic, ski faster when you can and you get quickly new realistic forecast from this App. Check values below. Average speed based estimates are also often too optimistic in late race. This App reacts quickly to pace drop and gives you early warning.

Don't panic, stride faster when you can and you get quickly new realistic forecast from this App. Check values below. After 10 minutes still 41km left, but forecast shows that pace is good enough to finish under 3h. Average speed based estimates are also often too optimistic in late race. This App reacts quickly to pace drop and gives you early warning. It's again time to stride faster to reach your target! I made this forecast based on my own experience in long distance running. This is something that I have calculated always during the race to estimate how it will end up. In future, I let this App handle the calculations for me. I hope you find it useful too!

This App shows your energy consumption as burned fat. Estimate is based on exercise intensity between moderate and hard. That's when your energy comes approximately 40% from fat. To burn 1 gram of fat, you need to burn 9 calories from fat. Longer explanation from livestrong.com: http://www.livestrong.com/article/388421-how-many-grams-of-fat-are-burned-during-cardio/

Press lap-button to set countdown minutes.

Get ready for countdown. This is THE App for the New Year's Eve ! This is new corrected version (without decimals).

There is different App for Males. Walk one mile (1.61 km) as fast as you can. Use 400m track OR treadmill OR find a flat route and measure distance using integrated GPS or calibrated Foot POD. After 1 mile this App shows your fitness level as Vo2 Max.

There is different App for Females. Walk one mile (1.61 km) as fast as you can. Use 400m track OR treadmill OR find a flat route and measure distance using integrated GPS or calibrated Foot POD. After 1 mile this App shows your fitness level as Vo2 Max.

MET (metabolic equivalents of task) tells you how much harder you exercise compared to resting on sofa. In practice, MET-values makes possible to compare your effort between different exercise. sleeping 0.9 watching television 1.0 writing, desk work, typing 1.8 walking, 1.7 mph (2.7 km/h) 2.3 walking 3.0 mph (4.8 km/h) 3.3 home exercise, light or moderate effort 3.5 walking 3.4 mph (5.5 km/h) 3.6 bicycling, 10 mph (16 km/h), leisure, 4.0 bicycling, stationary, 100 watts, light effort 5.5 jogging, general 7.0 calisthenics (e.g. pushups, situps, pullups,jumping jacks), heavy, vigorous effort 8.0 running jogging, in place 8.0 martial arts fight 10.0 Check more info e.g. from Wikipedia http://en.wikipedia.org/wiki/Metabolic_equivalent

This is for fun and parties :-) This App is for men! This App shows how much you have alcohol in your blood after drinking mugs of beer. You mark the number of mugs of beer you have enjoyed by pressing the LAP button AFTER you have drunk the mug. 1 lap = 1 mug of beer (0,5l, less than 4,7% of alcohol) = 18g of alcohol = 1,5 portion of alcohol I recommend to use 60s GPS interval with this app, so that the accu endures for the next morning and beyond. http://www.paihdelinkki.fi/alkoholineuvonnan-opas/promille Do not trust this for e.g. driving a car. Do not come to blame me if cops do have a different opinion. This ought to be close but it's still for fun :-)
