The idea behind this application is that it will help you track and manage your Vitamin D.

This new version integrates with the Apple Health app to make seamless data exchange possible in the following ways:

* on setup, profile information is fetched from the Health App if the user allows it
* the user's weight (a factor in D generation) is fetched on an ongoing basis, making it unnecessary to update it
* the app will write vitamin D doses, including session information into the Health app

You setup basic information one time, like your height and weight and skin type and then any time you are outside, during the prescribed hours (and parts of the year), you can have it compute the amount of D you are getting in a stopwatch interface. It will also track how long you can stay out and warn you when the time is up.

The application will notify you with the next opportunity to generate vitamin D.

Each day, you can see forecasts based on your location, and you can also see the solar position, your generated vitamin D vs. target etc.

In the Pro version, you can see your exposures' history and you will be able to schedule future events for next exposures.

Location bug

First, clearly, a lot of work went into developing this app. However, there appears to be a location bug. For example, if I enter a location in Rhode Island, it shows 63 days until the next opportunity as well as the weather for the next several days. However, if I change the location to, let’s say Rio, it’s still shows 63 days for the next opportunity, but does change the weather. If I leave the location on Rheo turn off the app then turn it back on it shows five hours for the next opportunity. If I then switch to Rhode Island, it will show the 63 days but then if I switch back to Rio it still shows the 63 days.

A lot of problems here

UPDATE: Don’t bother reaching out to the developer. When I made them aware of the issue on Twitter, with a supporting video/screencast of the issues below, they were rude and dismissive. I’m disappointed they couldn’t be bothered to take these issues seriously, and that they’d pass the blame on to me despite video evidence that their app has two serious bugs that disrupt a user’s ability to use it at even a basic level.

First, it’s defaulting my location to Saudi Arabia, though I’m in North Carolina. When I try to add my location, the map feature fails to find an address. Even when I manually enter my specific city, state, and country, it insists I enter the specific latitude and longitude of my location, which is incredibly bizarre. Never has an app asked me to manually enter my latitude and longitude. When I try to cancel the process of adding a new location, the app won’t allow me to return to its home screen. I had to force quit the app and reopen it to do so. I’m not sure how functional this app will be if I can’t even enter my proper location, and it’s suggesting sun times for a country halfway around the world.

Developer Response ,

You don't have to enter your location, the app gets it automatically. If you turn that on you will see that. That's why no one else is complaining about this.
