Can’t sign up.

Have entered all the details to sign up,and insists on putting +244 in front of my mobile number(incorrect country code) and then won’t let me sign up as I’ve entered an invalid mobile.

This app needs a small change

There is a technical problem with this app. It force the location to be on constantly and that drains the battery. As the iOS lets us to have a choice to use the location "always" "never" or "while using the app" in settings user should be able to decide which option to choose. UNFORTUNATELY the developer omit the third option "while using" and forced us users either never use such time saving great app or drain the battery constantly instead perhaps no more than a few minutes a day.
To developer: Could you please replay to this review, could you apply the third option to the app so we can take advantage of such great iOS?

Developer Response ,

Hi there,

Thanks for your review.

The Sine Pro app has been designed with battery efficiency in mind. Even with the recommended location setting of "Always", the app uses minimal battery. Please be assured you can in fact select "While Using the App", along with "Always" and "Never" from within the Sine Pro app page of your iOS Settings.

When your location is set to 'Always' for Sine Pro, you can take full advantage of our convenient geofence features such as: Auto check-out (Automatically check out from a site once you leave the vicinity), Check-out reminders (Reminding you to check out of a site once you've left the vicinity), Nearby site notifications (Providing a check-in reminder for sites you've previously visited).

When your location is set to "While Using the app" for Sine Pro, the above features won't function however you can still check in to sites (from the nearby sites list) and out from within the app.

When your location is set to "Never" for Sine Pro, you are unable to check-in as per above however can take advantage of our QR check-in (dependant on site configuration).

Our support team are available 24hr and will be happy to assist with any questions on the above.

Thank you again and we trust this answers your question.

Kind regards,

Team Sine
