JBV1 is nearing an open beta test. This week, I'm trying to finish the V1 profile functionality (settings + custom sweeps) and fix a couple remaining bugs. I hope to announce the open beta this weekend. After I fix any issues arising from the open beta, I'll release to production and begin working on alternate screen layouts (who doesn't like options?) and auto lockouts.
Also, since this is my first mobile app, I'm pricing it accordingly. JBV1 will be free and there will be no features reserved for a paid version.
