Announcing the release of version 3.5 of Sendero's iPhone GPS apps:

September 21, 2018

Thanks to continued funding from a federal grant from the National Institute of Disability, Independent Living and Rehabilitation Research, we continue to work on our seamless outdoor to indoor wayfinding functionality. We have added another indoor source, Ningo, and updated the existing, Loud Steps. We have tested the Loud Steps application in Chicago O'Hare airport, read about the airport tests on our blog. We have also added OSM points of interest to the existing Foursquare POIs and, thanks to an enthusiastic user, we now have Serbian language translation!

Warning: Before you install the update, share your user points of interest with your email; otherwise, they will be deleted from the app. You can then click on the attachment of the email on your phone to import them into the new version.

New Features

  • Added a new source of POIs, now in addition to Foursquare POIs, you can also access OpenStreetMaps (OSM) POIs.
  • Changed the "beacons" button to "indoor" on the POI screen to reflect the variety of indoor wayfinding support available.
  • Updated Ningo and Loud Steps SDK. You can use Loud Steps and Ningo for indoor wayfinding in buildings where location positioning is available.
  • Loud Steps is a WiFi based indoor wayfinding system, which allows for turn-by-turn directions. Available building are San Francisco Lighthouse, Envision (Wichita), Chicago Lighthouse, Merchandise Mart and 1871 Chicago in Chicago, National Federation of the Blind (Baltimore), and other international locations. Stay tuned for more buildings as they are added.
  • Ningo is an open source beacon database consisting of thousands of beacons. When you load Ningo for the first time, you will see a list of all the available beacons in your vicinity. Don't worry if your list is blank for now. We are regularly adding to it and have an online interface to make it easy for anyone to add more beacons. See for information on how to become a contributor. The Ningo database includes the OSM indoor beacons. You can create a "getting warmer" route to any of the beacons listed.
  • Serbian translation
