My watch is spot on every time I use it.

I can add anything I want. in initiated the comparison :-) my comparison my rules :-)

I guess you have trouble reading dude. I said in almost every post that the garmin stuff is top notch. but with top notch quality comes top notch price.

I can compare anything I want.

perform a certain function. please tell me do you KNOW what a cadence sensor IS #1 and how it works #2

let me explain for you. you take a 5 cent magnetic switch and a magnet. you put the magnet on the crank and then put the magnet switch on the frame so the magnet on the crank passes close to it. ever time the magnet passes the switch is closed.

no actual "data" is sent. just on off on off on off. now add in a 10 cent "clock" and you now have on off on off over time.

this is called RPM. revolutions per minute. that's it. that is ALL a cedence sensor is. nothing more. its measuring the RPM of your crank. do you have any ideal how insanely SIMPLY device and concept that is?

Lets get back to reality for a moment and leave your ARGUING for the sake of ARGUING and nothing else crap behind.

YOU stated your issue with the droid solution was the battery life.

I said turn off the screen.

YOU said "I want real time data while I ride ie screen on"

I said well you can still turn the screen off and install a cycling computer to "GIVE" you the real time data while your droid screen off records the DETAILED data in your pocket or bag.

YOU then said those things are expensive too and at that point you might as well just buy the garmin

so I showed you this information was incorrect you could in fact use the droid screen off (solving your battery issue) and use onboard cycle computers to give you your real time data fix.

I then as an experiment decided to see just how CHEAP I could go. and got it down to barebones $25 for everything the garmin does except the gps data logging.

what YOU failed the grasp is that the POINT of what the garming does is the GPS data logging. that is the only reason to buy the garmin.

for those of us who have a droid we can get GARMIN LIKE results without the garmin like price.

ask me if I care what my heart rate is? you know what my heart rate is 30 seconds after I start pedaling? 140 know what it is 2 minutes later? 140 what it is 30 minutes later? 140 what it is at ANY POINT IN TIME INSIDE their? 140 plus or minus 3

so a "watch" would work JUST FINE for me. but I had gadget cravings so I grabbed a scosche armband (I can not do chest bands Can't stand them) for $25 off ebay ($80 new)

and what do you know. the watch ALSO says 140 too. wow. seems accurate enough for me.

I am not a doctor. I don't really care if my meter says 140 and its actually 142. its irrelevant data for me.

and take a guess what a HRM is. wow its another RPM meter. a simple switch that pulses and how many pulses a minute in this case BPM beats per minute. another insanely SIMPLE device.

you seem to have this "need" a pretty silly need to defend your position and your position seems to be one of I bought this expensive garmin and I won't have someone telling me I could have done it for less or that I am not "special" for buying it.

I never said any of that but that seems to be the motivation behind your arguing.

this will be my last reply on this issue all together. why? we have gone decidedly OT.

this is an ANDROID APP FOR CYCLING THREAD. if your not using an android and don't want to discuss android apps. vacate.

I really dont get your passion to argue. Just because you do a lot of typing doesnt mean that you are correct. People lose interest.

Yes, I know what a cadence meter is but you state the obvious (how one works) but leave out how your 10c magnet trick tracks data and uploads it to a PC. Do YOU know how that data is recorded? Specific channels and pairings to the device? How do I build a receiver like that for 10c? I dont.

Then you state the only reason to buy the garnin is for data logging - but thats huge! Also, you wont look like a dork with all kinds of contraptions strapped to your batman utility belt to support what can be done with one device, the garmin.

You're also missing the point of the HRM. Its not good that you always get a 140 reading because that means you're either peaking constantly or not riding. The HRM is designed so that you can watch your HR rise and fall due to exertion. The garmin has built in alarms that sound when your HR enters dangerous zones. This was a must-have for me as I was 300lbs and wanted to track my heart stress on a ride. If you are happy that your device(s) constantly tell you a HR of 140, I dont think you understand the concept of a HRM. You should get a variable of HR unless your a zombie. Here's a garmin report of my HR on a 100 mile ride. Look at the HR fluctuations. They should NOT be static:

https://connect.garmin.com/activity/98675616

I agree the OP asked about Android software and I responded because I've 'been there done that' and then I read your lenghty posts where you're trying to describe building some contraptions that for you are 'so easy' but we mortals dont get it. Just as an FYI, Ive been in the software engineering industry for 10+ years so, dont worry, I can follow your ramblings - trust me

and here is where you use deflection to reflect your practice onto others and pretend its them.

I am 455 pounds and can only pedal so fast. my hrm is normal for the circumstances. I can't do "hit" training or anything like it. if I tried to muscle into the pedals I would shear my crank. again I am 455 pounds and I sheared two cranks on my trek before I learned that lesson.

I missed nothing. you have an extraordinary lack of reading skills. what I believe to be intentional. I don't think you understand the concept of reality. you live in your own little argumentative world. have a nice day.

out

I know what you weigh and I admire your will to get out there and do something about it. If we lived closer Id love to ride with you as Im a gadget geek too (X10, Robotics, RC Planes,...). Im 280lbs (started at 320 in 2010) so Im no shrinking violet either. I have no idea what 'hit training' is. I just ride my bike - rain or shine.

I dont think you see how you come off when responding to other posters. Read back through the thread - its not just me. Its OK to have different opinions but we dont need to attack each others reading ability etc. It makes people defensive believe it or not.

For me the garmin is the best thing ever. If you prefer to tinker, good for you. Just my 2c and nothing personal.

I know how I come off. go read my first reply then second then third. once you read my posts in context you will see that he is trolling and I got "less friendly" the more he trolled.

I don't know WHY I have to keep stating this over and over again. I have already said the garmin is top notch. the problem is its $500 and up. short of finding a 700 series for $300 (still crazy expensive) like he did I am not getting a garmin. (yeah you can get a 500 series for $300 but that is inferior to the droid solution to me ie leaves you wanting for more and still crazy expensive. 75% the cost of my bike)

if I had $500 it would NOT be spent on a garmin. ever. it would be a down payment on a heavier duty bike.

like I said garmin's are wonderful for this with lots of discretionary funds. not so great for those of us who can't aford the price tag.

a droid gives us 90% of what the garmin does at a fraction of the price.

and if you have BTLE a droid will EXCEED what the garmin can do. by a lot. and do it better.

You must be kidding! Look at what is for actually for sale!

Where is your data?

Again this is is utter nonsense. Look at what is for sale. No one wants something large and overly complicated (like the mess you were describing)!

What you are describing is a complicated mess.

More nonsense. You can get transmitters that are small (using coin batteries). The mess you are describing (with multiple AA sized batteries) is much larger and it's in addition to the transmitter. No one would buy something that large and complicated to use!

Actually, you are the troll. You can't be this dense in real life.

you say no one would buy that large and yet you have ZERO data available. NO ONE MAKES anything that large so you can NOT decree that no one would BUY something that large.

I would bet a month wages if you took an average joe not riding a $1000 bike and showed them a $40 setup that had wires and was the size of a deck of playing cards and said this will give you EVERYTHING that $500 garmin system does using your android smartphone your holding in your hands but will only cost you $40 and will run for an entire season before needing to be recharged (once a year) (HRM extra I don't need to design for them since there are plenty of BT3 and BT4 HRM's on the market cheap)

how much you willing to bet they would take the garmin?

What I am describing would have (to do what garmin does) ONE wire. this wire would goto the crank sensor and then ONE wire out of the crank sensor to the Speed sensor (just like your current sensors do it)

so WHAT mess exactly do you see? this wire would not even need to run to the handlebars. remember its bluetooth. put the box at the bottom of the seat post tube and the wire would only be a couple inches long.

what MESS are you imagining in your crazy imagination exactly?

where is the COMPLICATED part.

you attached the brain to your seat post tube. in run the less than 8 inches of wire (if that much) and attach the sensors. insert the battery and your DONE.

on your phone you "pair" to the brain box and stick the phone in your handle bar mount or in your pocket if you don't need to see it.

done.

where is this complicated mess your fabricating? enlighten me.

Where is your data? Your going on about data but not actually provide any makes no sense!

And the fact that no one makes anything that large IS data!

There's one BT3 heart monitor. There is one BT4 heart monitor (there will be others soon).

And you still need BT4 on the phone (which is the thing that your mess is attempting to avoid)!!

Why the heck are you talking about BT4??

It's a third ugly/large/unnecessary box.

With BT4, you only need a $60 sensor. And it's a real product that you can buy right now!

BT4 is likely to become common place on phones relatively soon.

Your idea is soon to be obsolete.

but I am not making statements of fact. you are. I don't need any data because I am not making gradiose statements of fact based on zero data. I am saying what "I" want. nothing more.

I am aware of at least 3 BT3 HRM's. Scosche - Zephyr -Sports Tracker

I mention bt4 so you can cry foul and say boo hoo my garming has HRM blah blah point is HRM is a separate device.

"It's a third ugly/large/unnecessary box."

its not large its not ugly and its not unnecessary (assuming you want these functions)

"YOU AND YOU ALONE with a few other exceptions" think its those things. thats your problem.

You can't say with BT4 you only need a $60 sensor (and then ignore the cost of the BT4)

and its $40 not $60. (cadence speed sensor wahoo $39.99) and then another $80 to $100 for the HRM (both both systems would need that so its a wash)

with BT4 you NEED a $500 phone to use it. you MAY NOT ignore that cost since I am aware of ONLY 3 phones that have BT4 (OF the MILLIONS AND MILLIONS AND MILLIONS on the market)

Iphone 4s - Nexus - S3

I assume the I5 just released also supports BT4 (its $700 I know I just sold one for the equivalent of that)

so thats 4 phones.

maybe in a few years you can blah blah blah about BT4 and ignore its insanely steep cost of entry.

and even when BT4 is common my idea STILL will not be obsolete. clearly you don't comprehend the definition of the word obsolete.

but all BT4 devices ARE ALSO BT3 compatible. not obsolete by any stretch of the imagination.

Dude - where do you get the energy from? I cant be bothered responding anymore. Imagine the actual riding you could have done instead of all this research and squabbling

I don't ride in the rain. and arguing on the internet is fun. especially when I am right.

Hello

I didn't go through the whole thread, so the subject might have been mentioned in one of the previous pages.

I'm just looking for an Android application that would beep at a given cadence so I have an idea of how fast I should spin to ride at a given cadence.
For the time being, I don't want to invest in hardware I won't use much; I just want to have an idea of what it's like to spin at 60-100 RPM.

Is there a simple app that does this?

Thank you.

Edit: The magic word was "metronome"

https://play.google.com/store/search?q=Metronome&c=apps

Simplest might just be a metronome app...set the cadence you want and pedal away. I just searched in the play store and found tons of free metronome apps available.

I have been using the wahoo fitness. It has cadence, heart rate, speed, time. At the end of ride it gives you all the averages, highs, lows and calories burnt. Works well with my Ant+ heart rate strap and wahoo Blue SC sensor. I was using Endomondo which I really like because is simple and looks nice but it doesn't work with my wahoo Blue sc sensor which I just recently bought. I contacted Endomondo about it but haven't got a response yet. Both work with Motorola Ant+ Heart Rate Strap which cost $25 new on amazon.

Yup, thanks, I gave it a try. In the city, even 70RPM is hard to follow

Were you saying it wasn't working for you? <confused>

I meant: I downloaded a metronome app and tried it today to see what it was like spinning at eg. 70RPM.
