TI-86A throw back from my undergraduate days. The TI-86 programmable calculator sure came in handy. Even had a swell time programming in Texas Instruments’ version of Quick Basic. Was pleasantly surprised when I stumbled on this app on Google Play.

It gave me back my TI-86, right there on my phones. Goes a step further by including other TI programmable calculators; TI-82, TI-83, TI-83+ and TI-85.

My Tracks

my tracksYou are a geek not a Christopher Columbus! Though I was very good in Geography in high school, I soon realized that it didn’t help much when it came to finding my way around Lagos (Nigeria) network of roads and its very mad traffic.

My Tracks records your path, speed, distance, and elevation while you walk, run, bike, or do anything else outdoors. While recording, you can view your data live, annotate your path, and hear periodic voice announcements of your progress.

With My Tracks, you can store your tracks with Google Drive, Google Maps, Google Fusion Tables, or Google Spreadsheets, or export your tracks to external storage. With Google Drive, you can also sync your tracks, share tracks with friends, and see the tracks your friends have shared with you. With Google Maps, you can share the map url with friends via Google+, Facebook, Twitter, etc. With export to external storage, you can select GPX, KML, CSV, or TCX format.

My Tracks uses the GPS sensor in your device to record geographic and velocity statistics, but the app also syncs with third-party biometric sensors, including:

  • Zephyr HxM Bluetooth heart rate monitor
  • Polar WearLink Bluetooth heart rate monitor
  • ANT+ heart rate and speed distance monitors (these require an ANT+ compatible phone)



How can I describe this app? Okay, let’s put it this way. If you were given a choice of a single app on your phone, by all means, this should be your choice.

Tasker gives you the tools you need to turn your smartphone into a fully-automated superphone. It gives you the tools to automate nearly any task on your Android phone based on certain triggers, resulting in some really powerful options.  It even lets you export your customizations and share with your friends as standalone apps. (WOW FACTOR!!!!)

It is not a free app, however, there is an offer of a 14-day trial at the developer’s website.

Alternatives to this app abound, but this in my opinion is the best in its category.
