Thank you for voting!
Please add a comment explaining the reason behind your vote.

You would have to be a retard to pay $50 for this program. Especially when there are better ones that are FREE.

The program did not work. Very irritating. The program refused to accept the code which was provided as part of the giveaway. I wrote to them and complained about it, but of course they ignored it.

I've seen a few people get this wrong ... Hex 'F' is equal to 15 and hex '10' is equal to 16. The sixteen hex digits (0-9, A-F) run from 0-15.

HotHot is confused enough without being misled on this one.

164 voters giving thumbs up to a piece of software that doesn't even do what it should.

Just goes to show that the entire "thumbs up / thumbs down" doesn't mean a thing.

To the author, you wrote :
"The reason this was written was — that yes, you can use google, or you can use something like onlineconversion.com — but, (a) there are tons of ads on some of the sites, (b) ‘free’ sites you have to really navigate through a bunch of pages until you find what you want — whereas with this software it is nicely packaged so you can easily find what you want when you want"

ROFL. All the alternatives that you mention have one big advantage over yours namely that they work properly. Secondly, the tons of ads according to you just goes to show that you don't know how to use the internet. Any truly decent freeware/opensource site isn't hard to navigate at all. Just look at the links I provided in previous posts to see that.

Your conversion calculations have so many faults in so many areas that it becomes a joke. I haven't used hex or binary in more then 15 years but I still know of the top of my head that F = 16 or that 0011 = 3. Your program can't even get that right. The amount of errors found and reported shows that there hasn't been any check if the program actual works as advertised.

Might not be worth $50 but this isn't a bad little program. It's not pretty but it's quick (and hopefully it's accurate) For myself, there might be lots of online converters but I hate to go searching when I need one and who knows when I need one badly then I might not be online.

Even with a price of free, this software is so broken it is still overpriced.

I could deal with it being trial software if it just worked.

The fact that the "programmer" just took a bunch of free snippets and packed it up and slapped a $50 price tag on it has to be criminal.

To those saying 'Stop whining. It's free'...Yeah. It's free today, but this person tries to sell it for $50 the other 364 days of the year. That is just ridiculous since it doesn't work.

So glad it installs well. So glad it doesn't crash your machine when you load it. Too bad it doesn't work as advertised.

Hope tomorrows offering is better.

First of all, thanks GAOTD for giving it away. Thats why we are all here; to get it free!

So, I do not find any logic in people bothering to ask why it was even given away.

Now for the quality and price of the product. I totally agree, it is overpriced, but it is business, its their choice to sell, it is our choice to buy or not. This product lacks quality though.

Thank you everyone for the useful comments, especially those people who really know their math and can make well-informed intelligent reviews.

To those who say "why are people being "B's" with an "itch" about the program when it's free... THINK!!! According to the mathematician's here, just imagine your child at chemistry class using a piece of software that is inaccurate. Normally they would add 1 drop of sulphuric acid to an experiment but this program says they should be adding 100 drops and your child ends up disfigured, or is crippled for life, or dies because of it, or the whole school burns down and multiple deaths occur because of it.

I haven't used a lot of my math for years so I'm not the one to say whether the decimal points are off or not, I will differ to experts on this, all I'm saying is if the math is incorrect then this could be a very dangerous program to count on and for that reason (the uncertainty of the accuracy of the program) I will not download it today.

Thank you GAOTD for offering the software, I look forward to what you offer every day, even if I don't download everything you offer. Your hard work is appreciated by all.

To everyone complaining about downloading a program to do this. Have you ever though God forbid... what if you didn't have the internet instantly at your disposal, for something like school? Not all school's (high schools especially) have internet everywhere (wireless) available to their students at their desks. A program like this would be very useful in my grade 12 University level physics class. So stop complaining, and come back another day. So what if it's normally $49.95, its free today! So accept it, or move on.

I'm sorry, but this is rediculous. No unit conversion software is worth anything NEAR $50 US. Hell, even $10 would be rather pricey. What's more is that there are plenty of programs with the same functionality that I can download for free. As a matter of fact, I could probably code a program like this myself with minimal effort and without spending a good portion of my salary.

There's simply no reason to buy this kind of thing when you could just as easily plug some numbers into relatively simple equations yourself. The person distributing this software is clearly a con artist -- an exceptionally poor one at that -- and I would suggest you fellows running GOTD stop distributing his products lest some of his ill-repute rub off on you.

At the top of the page it says "user rating:", this is totally false!! I don't know who they are but they are pissed or something, they go down the list and give everybody with good comments a negative and an enormous applause of plus for anybody who hates it. They do this over and over. All I said was I thougfht it was a good product, thanks gaotd and I'm negative 20 in five minutes????

#84 erroneously stated:
"What is everyone whining about the price of this software for? It is here, for FREE! No one has to pay $50. ..."

You obviously do not realise Giveaway of the Day HAS TO PAY for every copy of software downloaded and activated. It is clearly stated at http://www.giveawayoftheday.com/for-developers/

What I believe we've been seeing is rogue software vendors have increasingly using GAOD service in order to get a bundle of quick cash, with no interest in maketing their software. Some like this vendor are not even interested in their "products" being taken seriously.

I do thank the GAOD team for their great efforts to bring us chances to try out interesting and exciting pieces of software for free. But I would also like to caution the team to scrutinise more carefully the integirity and intention of the software vendors. I do not want to see the standards of software offered here being dropped. GAOD is too great the service to be used as cash cow by some jokers.

The links to the various alternatives are very useful. Thanks, #118, ken92111, for the link to Xyntec's freeware, whether or not it's any good, because they have a very handy comparison table of many unit converters, with links, including many mentioned in comments here, Unit Converter Comparison Chart. Of course, you should check to see if any particular converters that you're interested in have been updated since the chart was last updated. Also note that, in addition to Converber, Xyntec has Numerimal.

Was a no-brainer to guess on seeing today's offer there would be plenty of posts about free versions. I have tried many as I come across them, but keep coming back to the one Dave of post #2 mentioned
http://joshmadison.com/article/convert-for-windows , but I decided to try today's offer because it said;
"with the full version you can also create conversion tables between any two different types of values, plus, you can also convert a file of values automatically into another set of unit values all at once!!" thinking that would be a handy thing to have I downloaded, installed, registered today's offer. Per usual I didn't have a problem doing so.

I found that the application will not let me choose my own values for creating a table However with the default values of 0 for the for the lower value and 10 for the higher value, with 1 for the increment values, the application does create a table(text file) just fine. The inability set set my own values makes that feature worthless. Also the application doesn't have a decent help file so I can try to find out if I'm missing something. Could it be the;
the Single Licensed To:
is nothing more than the trial version?

I doubt I would pay the $30 discounted price in a month I had extra to spend. $50 for a conversion utility that doesn't include a water cloumn, is way out of line. On final note the application takes up 1.40MB of drive space.

There is no reason to defend this software. It is offered at an unreasonable price on the official site. If you test out the many conversion methods you will find that you need to double check it with a free program anyway and often to get the actual correct conversion.

This is free software promoting a company with terrible business ethics.

Thank you anyway.

There's a freeware converter that is virtually a clone of this giveaway:"Converber" at http://www.xyntec.com/. Believe me, there is no difference except a $49 price tag.

To me, it looks like HotHot Software needs to spend some time researching the multitude of freeware programs that are comparable to most of the programs they are advertising.
When I checked HotHot's site, I was surprised how virtually all of their products have freeware alternatives that have been around for quite a long time.

HotHot would be well advised to do this research and then ask themselves, "If I'm going to market a product that is competing against quality freeware able to do the same thing, what can I do to make my software stand out? What can I do to make my programs worth buying, what features can I add to make them superior to their freeware counterparts, etc?"

I was impressed with the wide array of categories that the Ultimate Converter listed although truthfully, I haven't used the freeware ones I already have because I've not had much need to convert anything when I've not been online, and when I'm online I just do conversions online instead of opening a prog to do them.

HotHot, I hope you will do some more R&D and come back with a product that impresses us all. Good Luck!

"Yes, even Google does it, if you can remember the syntax."

If you only want to do conversions through the command line you should better use the legendary units: http://gnuwin32.sourceforge.net/packages/units.htm
(download: http://ufpr.dl.sourceforge.net/sourceforge/gnuwin32/units-1.80.exe )... It has been working fine and with acuracy for decades.

Not only for private home use but even for scientific purposes this is the (free) software to have.

Being a Mathematician (real grad degree), I found this s/w total insult to my intelligence!

I am not going to go further into detailed examples, rather I would revert to what already was sited by fellow loggers:

b#23, #26, #27, #31, #37, #42, #43, #44, #46, #48, and #50!

Commercially, this is company would easily be sued for such faulty software!

anyone recall the Arian Rocket explosion (mid '80s)? why? because the software failed to do the conversion during paramerter passing from "feet" to "meters"!

I missed few major functions namely Boolean arithmetics, and polish notation! hmmm why thy are missing? Not the foggiest idea for such class of "calculators!"

HOTHOT S/w you are more interested in programming not mathematics, hence my advice for you is : focus on locking your programming code on native CPU i.e. 80387 or even the earlier 8087 code, for you to have the right "precision" calculations and conversion, and resort to newer CPU's fast clock cycle to achieve result. here you would have "REAL" results rather than CPU Dependant "floating point" calculations that would be totally unpredictable depending on whatever is on the Cash! *obviously the programmer did not bother to flush/reset the memory stack every time a new calculation is about to start! a.k.a AC button!*

this class of "programming" indeed require mathematicians behind the seen for quality control, not "ANY" good interface programmer!

a Plus for GAOTD team for trying, but no cigar!
a minus for GAOTD for not validating basic usability of s/w (quality assurance)!

I need not mention the alternatives, because my colleagues already did brilliantly pointing them earlier.

shall I bash the s/w authors? Naaa ... not worth it!

dear giveaway of the day

i've never left a negative comment on your site before, but i feel i need to leave one now. this program doesn't work. please test a program yourselves before offering it. offering something that doesn't work sort of makes giveaway of the day look bad.

Yes, [85.]. Comments are delayed, but that's because they're moderated I believe. So when the moderators check it, that's when it's put up.

As for [84.] Price is important. I reformat my computer yearly, and if I become accustomed to a program and then cannot reinstall it when I do, it's not fun. I'd rather be accustomed to freeware that I can install again anytime I want, and on any new computer also. Plus, I can share freeware with my friends. So I like hearing if there is a comparable (or in this case, infinitely better) freeware that I can get.

As for the utility of a non-browser utility, converter or otherwise, this is very useful for people with laptops in college. Wireless internet is not always functional, and many times I am somewhere without internet doing homework (ie: Starbucks, out of wireless range, OUTSIDE) and still need functionality. Programs like this (well, ones that work) can be used while say, at a park. It's nice to be able to get out, and until I can afford wireless broadband from a wireless carrier, little apps really help.

And many thanks to GAOTD. I'm usually not a fan of your programs, though there are some amazing exceptions (such as StarBurn! SWEET!) but I appreciate that they're there. This site brings together many people interested in free software, and even if I don't go for the daily giveaway, I find an alternative freeware. Aside from making money off ads or whatnot, isn't the main purpose of this site to introduce people to new software? I think they're succeeding!

For free this is probably a decent program, I would NEVER pay $50.00 for something like this. I have to admit I haven’t downloaded it and won’t since I have a FREE (all the time Free) program that resides on all of my computers and you don’t need to be online to use it, as some have said they don’t want to always be online for a conversion.

Try this one, I haven’t found anything it won’t convert and it’s always ready to go.

Okay I'm really sick of the joke software that's been given out the past few days. Why should something that converts units totally wrong and stores values in an incorrect base-16 format be worth anything? It shouldn't even be given out for free, rather trashed into the Windows Recycle Bin and then emptied.

GOTD, please BAN HotHotSoftware from giving any further jokes, especially that brain upgrade crap software. You stare at a screen and your IQ will magically increase? What a load of scammers.
