There is a great amount of talent out there, but we are asking for candidates in USA only, which will be required to sign an NDA. If you are outside of USA please don't apply. If you are in New Jersey or New York areas it would be a plus. Looking for a User Experience person that specializes in design of beautiful mobile applications that is simple to use, and pleasant to look at. Our target market isn't very technical so we put emphasis on the Experience part. Our application is being built on IONIC, so experience with IONIC would be a plus. Not sure exactly how many screens we will need, since multiple functions can be put on a single screen, that's another reason we need to look at you for your User Experience expertise. For quoting purposes let's assume 30 unique screens need to be created. Please provide a detailed proposal and how you are planning to conduct work.

We have existing apps in the iOS App Store and in the Play Store. These apps require a UI / UX refresh (already designed in InVision) and some bug fixes. SCOPE OF WORK: 1) We don’t want to change the underlying functionality significantly 2) We want to reuse most of the current app code if possible. 3) We are getting rid of the “sign-up” for the app. Instead, we will be doing a sign-in for the activity feature only (e.g. UA record) 4) We need to optimize the pairing / connecting experience at the front-end of the app. This is the most important experience and needs a refresh. 5) We want to keep the text changes to a minimum to ease the localization burden (we localize to many countries) 6) There are some key differences between iOS and Android that are accounted-for in the UI refresh. 7) We would like to integrate APPTENTIVE + ZENDESK (a) help people who require customer support from within the app and (b) request a rating when people are happy 8) We are changing how we turn notifications off/on in the app. 9) We will integrate better with Google Fit, Apple Health, and UA by reducing the amount of double-entry our customers need to make. Basically, if you enter your information in a linked app and that you grant our app permissions, it should populate in our app and avoid asking you to reenter the data. 10) We will need to add some new supported products to this app. These new products support new features. These will be described and need to be coded. The current app in the Play and App Store are called "CONNECTED WATCH". The new UI / UX may be found here:
