PrediSat is an Android app that grabs Iridium flare and satellite pass data from Heavens-Above.com and formats it for the small screen of the phone. It also includes a few features to make satellite watching easier, such as alerts, countdowns, and night mode.

Pro version

The Pro version (to be released) adds some advanced features on top of what is available in the free version. It may also include early features that will later be added to the free version. Development and release will occur after all major issues are eliminated from the free version.
Price will be $1.
Some features currently planned for first release:

  • Ads disabled by default, can be toggled.
  • Sightings log.
  • Adjust backlight brightness for night mode by numeric value, useful since different phones have a different minimum brightness.
  • Set multiple alert times (comma separated).
  • Automatic creation of alerts according to a set magnitude.

v1.0.4 [2010-09-02]

  • Fixed event timer timezone not being calculated properly for timezones different from phone.

Started development on 2010-06-29


Known issues

  • Clock is often off by more than a few seconds even when synchronized with carrier. Planned solution: Use an NTP server.
  • DST used is same as phone, so time is inaccurate if configured for a timezone currently using a different DST offset.
  • Timezone detection is extremely limited due to inconsistency between definitions in Java and Heavens-Above.
  • Repeatedly closing when launched. (reported by Spencer via Market comment) - Unable to fix without stacktrace or reproducible steps.
