    REAPP- its an app designed to increase social pressure around recycling. You can challenge your friends and post to social media how much you recycle. The data is used to help increase awareness about what is being recycled and more importantly, what isn’t being recycled.

    I downloaded Re-APP, which is an app that socializes and incentivizes recycling and reusing items by allowing users to catalog/inventory the items that they recycle or reuse. The list is added up on a leaderboard, which lets the users compete against each other and their friends to see who can recycle or reuse the most. I think they’re adding some more features to start making it a one stop recycling information app soon, too. or

    Catalog Spree. The free app offers a smart green alternative to paper catalogs – it provides access to 350+ catalogs from 200+ brands on your iPad, iPhone or web. Every year the catalog industry generates $110 billion of sales through the 19 billion catalogs that are mailed to American consumers. That makes for 53 million trees consumed and 3.6 million tons of paper used.

    KeyLogic Systems, (through its participation in DOE’s “Apps for Energy” Challenge), developed a Green Button application called Kill-Ur-Watts that permits residential customers to view, track, and manage their residential electricity use over time. This application utilizes common industry-based concepts and third-party data to empower residential users to make informed decisions on energy reduction strategies and implement common-sense energy efficiency improvements.

    Currently only for the iPhone (can run on iPad and iPod Touch) this app is getting ready to undergo a major overhaul which is to include an Android version.

    With the app, you can:
    – See your monthly, daily, and hourly electricity usage.
    – View graphs of your usage.
    – Pinpoint peak time usage.
    – Get tips on how to reduce your energy usage.
    – See your Energy Score (or Energy Usage Index) as compared to the national average.
    – See your Carbon Footprint as compared to the national average.
    – Setup the energy using devices in your home and view a pie chart of where your energy dollars are going as compared to a typical single-family home in the USA.
    – Challenge your friends and family to lower energy costs through twitter integration.

    Our web app is called, “Should I Wear Sunscreen Today?” It’s a simple, sleek web app; all users need to do is punch in their zip code and they’ll receive a clear “yes” or “no.” Our answers are location-specific, sometimes funny, and always relevant—we base results on official EPA recommendations regarding UV levels.

    Appuga recently uploaded two apps in the Appstores of both IOS and Android Platforms, and both for smartphones and tablets. These two apps are the following:

    * CO2 Pro: It calculates a company’s CO2 emissions, expressed in equivalent tonnes. See

    I’m America’s go-to guy for foraging and the author of Wild Edibles, the definitive app for edible wild plants. It contains everything I know about the herbs, greens, shoots, roots, nuts, seeds, berries, and seaweeds that people overlook or destroy as “weeds.” You can learn how to identify them with the 100% certainty you need before you eat them or use them as home remedies. I cover all their characteristics, as well as habitats, ranges, edible, non-edible, and poisonous look-alikes and relatives. I use original drawings and paintings, as well as photos depicting all stages and forms of these plants. I’ve also got hundreds of healthy, delicious, innovative vegan recipes. There’s a free lite version, as well as full versions of the iPhone, iPad, and Android devices. My development team, Winterroot, and I are continuing to add more material and features with each update. Go to for excerpts. Happy Foraging!

    Hi. Definitely recommend the iFixit app for access on how to repair a range of consumer products yourself. The website allows you to purchase spare parts and tools, but these are also available through other routes such as computer auction websites if you prefer to get them that way. You can also add your own repairs to contribute to the community.

    Lexicon of Groundwater and Water Well Terms
    By National Ground Water Association

    This is a useful tool for students studying hydrology, hydrogeology, or other environmental fields as well as those already working in groundwater-related professions.

    At The Groundwater Foundation we recently launched Water1der. It’s an educational, trivia based game.

    Through a fun educational game, players test their knowledge about groundwater, pollution prevention, conservation, irrigation, the water cycle, aquifers, recycling, water sheds, water use and wells. Players will “spin” a wheel on the app to determine the topic of the question. The formats vary from traditional ones, such as multiple choice, word scramble, matching and true/false to formats such as drag and drop, where players can move words to areas to label parts of the aquifer; moving, where players can select an item to be placed into the correct area; scrolling, where players can click their finger on the right answer as it moves across the screen; and timer, where players will touch the screen to stop a timer at the right number.

    It’s available on the app store now for ipads at
