Developer here. Thanks for checking out my app, Riker. In case anyone is
curious, the iOS app is native, written in Obj-C. The Riker web app is written
using React and Redux. The REST API is written in Clojure and the backend is
Postgres.<p>Although there is also a fully functional web version of Riker, the app is
preferred since it supports offline mode, provides Watch App and integrates with
Apple's Health app.<p>Will be happy to answer any questions.<p>App Store link: <a href="https://itunes.apple.com/us/app/riker/id1196920730?mt=8" rel="nofollow">https://itunes.apple.com/us/app/riker/id1196920730?mt=8</a><p>Web link: <a href="https://www.rikerapp.com" rel="nofollow">https://www.rikerapp.com</a>
