Clew is an AR indoor navigation app designed for visually impaired users to help them retrace their steps in unfamiliar environments.

What’s New

Version 1.1

A lot has changed in this version! We want to thank folks for reaching out with helpful suggestions and feedback to make the app better. We are committed to continuing to act on your feedback to improve Clew, so please keep it coming. There are still some features we have not had time to implement yet (most notably support for languages other than English), but these are coming over the next several months.

The following new features have been added to Clew.
- Routes can now be saved so that they can be navigated repeatedly.
- Routes can be navigated in the forward direction (i.e., the same direction as they were recorded) as opposed to just in the reverse direction (as was the case in prior versions of Clew)/
- Enhancements have been added for users with low-vision, including bigger fonts and buttons, better placement of on-screen text, support for voice announcements even when the user is not using VoiceOver.
- Motion tracking errors are now communicated directly to the user. This will result in your phone generating more announcements when conditions are not good for motion tracking (e.g., poor visual features in your environment or excessive motion).
- We have added a new pause and resume process that is more user friendly

Make sure to read through the "Help" menu for a rundown of how to use these new features.

Great app! Fantastic concept!

Just downloaded this app from App Store. Used it to go from our living room to our bathroom and back in our apartment. Absolutely amazing. At present, seems that you can only record one path at a time. One thing that would make this an absolute perfect app would be if you could record multiple pathways at once. Four instance, it would be nice to be able to record a path from the entrance to a church to our Sunday school class, followed by a path from our Sunday school class to the church sanctuary, and then back to the exit of the church. Or, can this be done already? Or do you have plans in the future to upgrade this, making this action possible? Right now it’s a great app and I would give it probably four stars, just because of the single option to record pathways.

Extremely accurate

I have tested and used this app a few times. I find it incredibly accurate when it comes to backtracking and navigating in places that may or may not be very complicated to get around as someone who is blind or visually impaired.
This is a great step two helpful apps for the blind and low vision.

can't figure it out

I was looking through the app's features but when I try using it, I don't see any of the haptic, speech or sound options. Also, do you have to keep pressing the button or will it automatically speak from point E to point B?
