HVAC buddy is a great app. Needs refrigerants added though. Another app thats pricey but excellent in my opinion is HVAC Load calc bundle by carmel.

.

I use my Flirone app a lot.

Is my Favorite.
..

I used the Ultra-Aire free app for estimating the amount of moisture being removed from a cooling coil.
Plug in the temp/%RH and out, estimate the cfm provides lbs. per hour condensate. Will do the reverse or any missing part.
Works with a/c, humidifier, or dehumidifier.

Hi Buddy Lee, what is your take on the Carrier Enterprise App?

I know.

I gave it a half a$$ed effort about 8 months ago. Tried to find or make a math formula for it but was unsuccessful.

Seems we will need to input the chart and then pull averages out of it for 1 degree increments.

Not unless someone has a formula for it and would like to share.

I know it can be done though with the chart.

My new HVAC Flat Rate App has been keeping me kinda busy during the last 6 months.

Back when I was using a PDA, I used ExactCharge all the time.
I'd switch back to it from HVAC Buddy if you would add target evaporator exit temperature calculation to it...

Bitzer PT app, Weather Channel, Converter+ for iPhone and sudoku.
iBooks is great for manuals and PDFs

I use the dupont PT calc and ibooks. PDF management is essential. Thats all I use my ipad for.. so my manuals don't take up all my cab space.

Bitzer refrigerant of pt chart, Dropbox for storing all those manuals and videos on equipment.

PDF reader, to read those manuals on pesky equipment.

Cam scanner, for scanning receipts and sending them back to the office for billing.

Dupont's PT Calc is a good one to have on hand. FREE too.

Does anyone have a PT Chart app that they use and love?

Also, does anyone use a PT Calculator app for Superheat and subcooling calculations?
I have been looking at them also and not too impressed with what I have found so far.

I have that one, and also have KG Free, and 3D knots.
It's amazing how the human mind works (or doesn't). there are really complex things I could tell a 3rd grader to do over the phone and fix a chiller, but yet knot tying just slides right out of my mind lol

The Bitzer PT app is a good one. Free.

iBooks is great for storing various manuals. Free

Munters put out a good Psychrometric app. Free

Which knot app you have??? The best one I have seen is "animated knots by Grog".

I use blitzers on a regular basis. I also use coplands X-Ref a lot. Its useful for getting info on copeland compressors like nameplate data and replacement options. I also use dewalt mobile pro a lot. Its a construction calculator and a conversion app all in one. I also use the iHandy level a lot because it seems like I never have a level near by when I need it. I use Convert Units for exactly as it sounds. Thats the best conversion app I have found. I use the internet on my phone at least 30 times a day, anything I dont have on my phone is on the internet. I use HVACBuddy during the summer. It is also the only app I have paid for. Its a useful tool to document reading but for the most part no app will replace skill and knowledge.

I have a fair bit on my phone...
Adobe pdf reader.
Camscanner+, this is awfully handy, you can take a picture of a form, and it turns it into a pdf image, so you can email it as something better than a picture.
KeleCalc is awesome for converting units from one to another.
Siemens eAssistance is kinda cool too, you can scan the barcode, or model number off of a siemens contactor and get information on it.
LorenCook has their engineer's handbook out too... some useful once and a while info in there.

I have most of the Danfoss apps, only really use the refrigerant slider though.
Bell & Gossett has a product app that's not too bad if you deal with their pumps a lot, Taco has one too.

I have a knot app too, cuz I SUCK at tying knot's.
Hill Climb Racer... great app to finish off lunch time! lol
