I started using an Android phone three months ago and since then, I have been searching for some apps that would fit my needs as a teacher. One of the apps that I have been using which was really useful to me is Foldersync. It enables you to sync your cloud storage with your local mobile phone storage. You can also use it with your phone’s SD card.
What I like most about Foldersync is it enables you to sync a specific folder and not your entire cloud storage with your phone. In my case, I only have a 64GB storage, so I did not want sync my entire Dropbox to my phone because it will take up a lot of space. I use a specific folder to sync my electronic books folder on my Dropbox and my phone.
Foldersync at Google Play Store
Foldersync supports the following locally and on the cloud: updating of files, copying, moving, and deleting files, and creating files and folders. Although I have not tried it yet with other cloud storage, it works perfectly in my experience with Dropbox. It has a free version (the Foldersync Lite) which contains ads and it also has a premium version. I’ve been using the free version for three months already and I am perfectly satisfied with it.
Foldersync is also compatible with Google Drive, Amazon S3, Godaddy, Amazon S3, OneDrive, OneDrive for Business and many others (see full description on Playstore). It is available for Android users and can be downloaded from the Google Playstore. There is also a very detailed setup guide at the How To Geek website.
If you are looking for free math resources, I found a website that offers peer-reviewed math ebooks for college and AP Courses. This website is OpenStax which is based in Rice University and supported by several foundations. Below are the links to the math ebooks.
Aside from the math ebooks on Science, Social Science, Humanities, and AP Courses are available on the website.
For more free resources, you can visit Math and Multimedia’s All for Free page.
I am a fan of free apps and I have promoted a lot of them in this blog, but there are times that I also purchase premium apps. For the past few days, I have been exploring Wolfram Alpha for iOS which can be purchased in iTunes for $2.99. For those who have not heard about it yet, it is a knowledge engine developed by Wolfram Research. In layman’s words, it is an engine that answers factual queries and returns curated data rather than a list of files or web pages which is what search engines do. For example, if you search “primes between 1 and 100,” it returns the list of primes as shown below. To know more about Wolfram Alpha, you can read my introductory post about it here.
Wolfram Alpha covers a wide variety of topics. This includes mathematics, linguistics, dates and times, chemistry, money and finance, physics, health and medicine, engineering, geography, transportation, weather and meteorology, and many more.
Another unique feature of the iOS app is it is directly connected to Siri. You can just ask Siri about your queries and Siri will return answers from Wolfram Alpha. For devices without Siri, you can also type your queries. In iOS devices, a special keyboard with mathematical symbols appear every time you access Wolfram Alpha.
You can also download the FREE Wolfram Alpha Viewer to explore Wolfram Alpha results from Siri and learn how to use the commands effectively. You can also access Wolfram Alpha online.
