thanks for the app. another useful tool.

Nice work, keep it up.

Very slick, thanks for making this!

Just wanted to say Thank You for the app you made I love it

Hey everyone. Getting ready for the season in Northern Michigan. I'm too lazy to boil water to calibrate my thermometer and do basic math......so I made a web app that calculates it for me based on Weather Underground data and the location services of my iPhone. It should work on any mobile phone. Check it out and use it if you want...

Tip: Once the app opens in your browser you can use "Add to Home screen", it has a nice icon.

Tapatalk users...please note clicking the link to my app doesn't work from within Tapatalk. They display external links within their app and this doesn't allow the location services to work. iPhone/Safari users can click the Safari compass icon in the lower right corner of the tapatalk window to launch it properly. Android/Chrome users can click the menu in the upper right (looks like three dots) and choose the option for "Open with" and that should properly launch it in the browser.

Have to add my big Thank You also. I've used your app since you posted it to get me within ballpark of syrup. I would check the app everyday I went to boil and if it said 219 when I hit 219 and tested the syrup in my hydrometer it was spot on. Thank you again.

Good question mellondome. I'm not doing anything with elevation and that should not technically be necessary. The only reason water has a different boiling point at higher elevations is a function of the atmospheric pressure at higher altitudes. So it's possible to use an altitude corrected calculation. Here's what I'm doing...

I'm using the pressure readings from Weather Underground which are calibrated using MSLP (mean sea level pressure).

And I'm basically using the calculation of Table 2 found on this page and several others on the web.
http://www.hi-tm.com/Documents/Calib-boil.html which is:
Boiling point = 49.161 * Ln (in. Hg) + 44.932

The one thing I would recommend in regards to elevation is that you know the location of your closest weather station the app used for its calculation. I report that right under the temperature readings. If your boiling at a drastically different elevation than where the reading came from you might want to make an adjustment. That's actually something I might try and add to my calculation here soon. As mobile devices get better at reporting their elevation, I could techically correct it against the difference in elevation to the weather station.

I ask only because my Samsung phone has a barometer built into it. So it gives me the actual pressure where the phone is at. ( Also great for measuring elevation change on lines).

I also now have a weather station next to the sugarhouse.

Thanks for the feedback everyone glad to hear the app is getting used. Still waiting for a good run to boil up here in Northern Michigan.

Mellondome, that's cool you have a weather station at your shack. Is it registered with WeatherUnderground and is it getting reported to my app?

Thanks! One less gadget that I have to buy

[mellondome]

It shows up in the app.
Being at 2000+ ft elevation, there is just over 2" Hg difference in msl pressure and actual pressure.

Great App! Thank you! strange that I have a gold star rated weather station and it used my neighbors station instead.
