#iOS #App – 10 nice apps iPhone or iPad on sale for free a limited time : There are some applications which will going to be spending a good amount of money holiday season. Save a few extra bucks each day with our daily lists of paid iPhone and iPad apps on sale for free.
Today, we’ve got even more great apps for you to check out. Some of yesterday’s freebies are still on sale as well, so be sure to check them out right here. These are paid iPhone and iPad apps that have been made available for free for a limited time by their developers. There is no way to tell how long they will be free.
These sales could end an hour from now or a week from now – obviously, the only thing we can guarantee is that they were free at the time this post was written. If you click on a link and see a price listed next to an app instead of the word “get,” it is no longer free. The sale has ended. If you download the app, you will be.

“Wow. First of all, please let me say that this is the single best iPad application that I have ever used (not to mention one of the best structure drawing programs on any platform). You really nailed using gestures to design and manipulate structures. The app is an awesome example of harnessing the spirit of the iPad. I was up and drawing in 30 seconds. The interface is clean, intuitive, and so very well designed. Beautiful output too.”
“I use this for all my structure drawing needs now – desktop applications are so expensive and actually harder to use than Chirys Draw. Developer is very responsive. Improvements to the app keep coming. If you’re a student, or a lecturer like myself, and need to draw quality chemical structures, then look no further. Exporting features make it easy to create a structure, then email to yourself for incorporation into a Powerpoint, Keynote, Word or any other sort of document. Highly recommended, and well worth the cost (much cheaper than desktop apps and for most purposes just as functional).”

“Extremely well-done, very easy to learn, and elegant. It will be easier and faster other competitors to sketch high-quality structures and could be really handy for taking notes in meetings.”
“Brilliant addition to the iPad workload. This is clearly a creative application and the most full featured molecular drawing app. I think the developers here have the most motivation, and have put more original thought into this. I hope they will be encouraged to continue with their vision…”
“I wanted to let you know directly how much I appreciate this app. It works exactly as advertised, is highly capable, and is now substituting for a desktop-based chemical structure drawing app. I am right now using it to prepare structures for my pharmacognosy lectures, and it is working well.”
“The words that come to mind: Impressive. Quality. The development of Chirys Draw shows your deep, consistent, and scholarly chemistry flair and precision, and is impressive. Professional chemists will continue to love this.”
“ChirysDraw represents the best chemical drawing package to date on the iPad.”
“Thank you again for such a lovely program.”
