VdN App and MySkyAtNight wishlist

How can we improve the app?




Your feedback helps us improve the app. We don't currently have funding for further development, but hopefully that will change in the future, and we can do one final change to the method, and then fix it for a long period. If you have more suggestions for how to improve the app, please let me know in the comments.

Things to change/improve in a future version of the app

Star search

  • Further improve star selection based on app data (preferentially use easier stars)
  • Make more use of "pointing stars"
  • Allow search to start with Venus or Jupiter
  • Allow the user to change the sensor settings (speed and/or damping)
  • When screen is frozen, allow navigation by sliding finger 
  • Option in settings to not lock screen when star is found
  • Shaking the phone unlocks the locked circle (goes back to arrow) 
  • Try to work out that the user is standing on a balcony, and don't suggest stars in that direction 
  • Allow the user to adjust the number of stars displayed on the screen to match a given skyglow level? (we don't want to do this, as this could potentially cause biased observations)

Usability

  • Figure out what causes the occasional crash on startup
  • Strategies for classifying areas with NELM>5
  • Interface to allow advanced users to submit what their estimate of the limiting magnitude is
  • New "constellation mode". Highlights a single constellation, and the user has to click on a star to declare it visible (turns from dot to star) and click a second time to declare it invisible (turns from star to empty circle or x), click third time for "just at visible limit"
    •  Or extend this mode to cover several hundred stars over the whole sky, and the observer can just pick which ones she wants to label?
  • Manual way to calibrate the compass to remove azimuth error 
    • Add a compass-free option in "settings" menu for places with weird magnetic fields
  • Investigate behavior of auto brightness on Android (does it turn to full on app startup for some phones?)
  • Allow "SQM only" install for phones without gyroscope/compass 

Community

  • Badges - you've observed 7 stars, you've repeated an observation at the same location ~1 year later, you've done 10 observations, 5 times in a single city, 5 locations, etc...
  • Guide users to locations that we particularly need measurements (e.g. repeat measurements from previous years).
  • Incentivize good data: Have a friendly competition where the best quality and quantity is rewarded (with a visit to the closest telescope and a personal lecture from an astronomer). Reward observations in particularly important locations
  • Welcoming email to new participants
  • Option to have your observation results emailed to you after each session
  • Add option to user settings that data is visible on the public map. Make the user choose which setting they prefer when they conclude their first observation.

Extra features

  • Check the clock using GPS and warn the user if their phone's clock is off by more than 2 minutes (and then exit app). Prevents records having a false time
  • Allow option of displaying user's location on a map to make sure it is correct
  • A "talking" tutorial that tells you how to find the stars, asks you to turn in different directions, etc.
  • Video tutorial
  • Allow observing below 45 degrees and making maps of the stellar visibility on the full sky dome (expert mode)
  • Find a way to calibrate the compass within the app (on Android, iOS already has this)
  • Port to WindowsPhone and Blackberry

Technical

  • Start looking for GPS location on app start up, verify again before star search
    • Especially for SQM report, GPS should run in the background while typing value
  • Reduce the size/thickness of the circle during the star search on Android
  • Better messaging in "Not dark enough" menu during high latitude summer 
  • Allow users to add SQM serial number, and SQM-L or SQM
  • Remove names of unused stars & constellations, to make it easier on the translators

My Sky at Night

  • Allow users to customize font size and color, and background color

Now it's your turn. What other changes should we make to the app?

  1. The left side column of the app have many unknown options . it can be removed for better UI

  2. Hi Sam,

    I'm not sure what you mean by "unknown options"? Each of the buttons does something.

  3. Ability to zoom in/out or move once locked on star. Include Dark Sky Meter readings in Submit data from SQM.

    1. Hi Mike,

      Navigation when frozen is on the list already, with relatively high priority.

      It's very important that you don't submit Dark Sky Meter readings as SQM readings. DSM observations are already automatically sent to Globe at Night and included in www.myskyatnight.com, so there is no reason to submit them twice! You can download data in a selected region with www.myskyatnight.com for your preferred mix of sensors (e.g. DSM+SQM).
