My more recent app, the Barcode Data Sampling Compiler, can be found at Google Play. It was created in 2014. It allows the user to scan standard barcodes, compile them into a CSV-format, and send them via email. It was made to be able to better-track parcels and other barcode-related data at NDCs.
More information about it can be found at the above link for Google Play and also at my other website.
Here is a screenshot of one of the other Android apps that I made in 2012 - TextMaster
When a text is received, TextMaster can automatically provide a default text response.
It also has the OPTION of automatically providing the current location of wherever you're located to the sender of a text in a linked text response.
Another option that it has is that it will speak the received text aloud so that you don't need to view the text.
It can also handle voice dictation, thus converting your speech to text, which can be automatically sent to the last number of a text received (or changed if necessary).
It requires SMS and GPS to be in use, and may use data when activated, interfacing with Google Maps for data and GPS capability.
It's currently in use on my Android Galaxy S3. You can download it for free at the link below, but it requires you to allow third-party programs from your settings.
Making apps has been a hobby of mine. I have posted a few apps that I developed (the app mentioned here, an app for finding local recreational places to go in the Greater Cincinnati area, and another for finding stock quotes quickly) at my other site, USA Apps, and plan to eventually make them all available for free on Google's Play Store.
