Comparing Half-Staff Alert Sites

Results of 60-day case study, from April 21 to June 19 of 2019, comparing half-staff notification accuracy of 5 services:
[ Measured # of days 100% correct list of ALL states with US and/or State Flag at half-staff ]

Service (Site / App)	Rank	Score (% correct)
FlagSteward (App & Site)	1st	55.5 of 60= 93% accuracy
FlagsExpress.com/HalfStaff	2nd	26.5 of 60= 44% accuracy
FlagNotify.com	3rd	12.5 of 60= 21% accuracy
"Flag App" by Colonial Flags	4th	7 of 60= 12% accuracy
"Flag Day" (pay for) App	5th	5 of 60= 8% accuracy

Explanation of Accuracy Score: For example, FlagsExpress' score of 26.5 of 60 (44% accuracy) means that their listing of half-staffs were 100% correct on 26.5 of 60 days. There were many days when their site may have listed most, but not all, like 2 of the 3 states, that were at half-staff. But, that did not count as an 'accurate' day because their listing of half-staff states was not 100% correct.

Why does Flag Steward proclaim to have the most accurate and comprehensive half-staff alerts?
It's not because we're trying to pat ourselves on the back ;) It's just a sign of the care and attention to detail we give to commemorating those who their nation, state, and/or local area want to properly honor. The Flag Steward site and service has up and running for 1 year now. During that time, we've noticed how often other half-staff alert sites are incorrect, so that's why we set out to be better stewards of Our Flag in all states. And, it's not an easy thing to do - to get the half-staff status for all states accurately and on-time. Unfortunately, every state alerts its citizens in different ways (like bulk emails, RSS feeds, Tweets, etc.) and many are not easy to follow or posted on-time. In the last 6 months, we have improved our half-staff alert quality as well as the presentation of such alerts - to the point where we proclaim to be the most accurate and comprehensive. But, that doesn't' mean we're 100% accurate either - just more than others providing the same service. We have one last layer of communication that we'll add in the next few months to maintain and extend our highest accuracy And, we know national, state, and local area Flag orders don't have to be followed by citizens. But, if you have a US Flag, it's just the right thing to do - join and show unity in commemorating those being honored by your national, state and local governments.

Highlights of half-staff report differences from each site for select dates

... comparing Flags Express, Flagnotify, "Flag App", "Flag Day" app, and "Flag Steward" site & app ...

Evidence supporting Flag Steward's 30-day and 60-day studies of its half-staff accuracy versus other sites & apps starts below.

Posted here is another recent example of Flag Steward's greater attention to detail compared to others. Many of the Governor Flag orders do not have an ending date, the date of interment (burial) when they are first posted. And, most Governors do not send out another order to return Flags to full-staff at sunset on the date of interment. So, Flag Steward researches, verifies, and publishes the ending date (date of interment) on its own.

Whereas,other half-staff alert sites & apps, like FlagsExpress and Flag App, DO NOT!
Most of FlagsExpress' half-staff accuracy errors relate to not effectively informing states when their half-staff remembrance has ended. For example, today's (June 27) FlagsExpress half-staff listing has 3 half-staffs that ended (see pic below):

MD half-staff for former state legislator Clayton Mitchell Jr. ended on 6/21 (6 days ago)
CO half-staff for Fallen Trooper Moden ended on 6/21 (6 days ago)
WI half-staff for Fallen Officer Hetland ended 6/26 (1 day ago, and another is going to start on 6/29)

Ongoing, randomly selected reports of Half-Staff alerts

Since the end of the half-staff accuracy study, Flag Steward continues to outperform others - including newly found Legacy.com half-staff alerts

on July 25, 2019

The correct half-staffs across the USA are ...
Half-Staff Alerts for July 25
The US Flag is FULL STAFF across 49 of 50 States. US Flag across NY is half-staff
And, local half-staffs are happening in IN and NC
NOTE: In New Mexico, the NM State Flag is to be lowered to half-staff starting at sunset today (an unusual time) to honor a fallen firefighter.

Unfortunately, ...
Legacy.com is confusing today... This morning it listed the NC Zoo half-staff for July 15 and then later in the day the NC half-staff was gone and the NM half-staff was listed for July 25 - when in reality it starts at sunset on July 25 and goes through July 26
FlagsExpress.com is missing the Governor-ordered half-staffs in NM and NC
FlagNotify.com is missing the known Governor-ordered half-staffs in NY and NM (and AR's has ended)
Colonial Flag's "Flag App" is missing NY and NM (and AR's has ended)
And, Flag Day App, a pay-for app, is always wrong until there's a National Half-Staff because they don't monitor State half-staffs
[Pics of pages below]

on July 12, 2019

The correct half-staffs across the USA are ...
Half-Staff Alerts for July 12
There are no statewide half-staffs, but there is one State Capitol half-staff order in FL.
Also, there are local half-staffs in FL, WA, NC, & MA

[ NOTE: Only 2 of these 4 half-staffs are verifiably ordered by their State Governor (FL & MA). Flag Steward assumes the county-wide half-staffs in WA & NC have Governor approval, but it is not known. So, we won't hold missing these half-staffs against other half-staff alert sites. ]

Unfortunately, ...
Legacy.com is missing the known Governor-ordered half-staff in FL
FlagsExpress.com is missing Florida's State Capitol & local half-staffs (which we know were ordered by the Governor)
FlagNotify.com is missing the known Governor-ordered half-staffs in MA & FL
Colonial Flag's "Flag App" is missing MA & FL
And, Flag Day App, a pay-for app, is always wrong until there's a National Half-Staff because they don't monitor State half-staffs

The US & State Flags across MONTANA, MASSACHUSETTS, & NEW YORK are at half-staff.
The STATE FLAG in Maryland ends its half-staff at sunset.
And, locally the US & State Flags are half-staff in Cowlitz County, WA

Flags Express states:
(See page image below = is MISSING alerts for NEW YORK and MARYLAND and very rarely shows county or city half-staffs)

Flag Notify states:
(See page image below = is CORRECT for all statewide alerts... is missing Cowlitz County, WA because they very rarely show county or city half-staffs)

"Flag App" by Colonial Flag Co. states:
(See app page screenshot image below = is MISSING alerts MASSACHUSETTS, NEW YORK, & MARYLAND... along with Cowlitz County, WA because they very rarely show county or city half-staffs)

"Flag Day" app states:
[ See page image below = is always MISSING ALL STATE HALF-STAFF ORDERS from Governors because they ONLY DISPLAY NATIONAL HALF-STAFF ORDERS ... Additionally, this "Flag Day" app doesn't even show the proper, recommended days for flying ones US Flag. First of all, the next "Flag Day" listed is April 21, 2019, Easter. I've never seen a list of government recognized Flag Days that includes Easter (as a devout Christian I'm all for it, but...). And, just in the past few weeks, the app missed the 'National Vietnam War Veterans Day' (March 29th every year) and 'National Former Prisoner of War Recognition Day' (April 9th every year). For a paid app to not provide state half-staff alerts and miss important, nationally recognized "Flag Days" is UNSAT! ]

[ Note on own accuracy deductions: On May 1, Flag Steward was first of 5 sites to post alert, but still 3 hours later than email receipt alerting to NC State Flag half-staff notice. And, 2 hours late verifying that US Flag half-staff in MD was ended early by Governor at sunset on April 30. So, docked self 0.5 for tardy alerts. On May 2, FS was a few hours late posting Nevada's flag order for today. On May 4, found NV half-staff alert via web in the evening, instead of email alert, and seems no other sites have acknowledged it as of morn of May 5. On May 14 & 15, late to post IL & MI half-staff alerts. On May 30, missed immediate half-staff for MS, but got it next AM, when others had not. On June 17, missed immediate half-staff order in late afternoon from WV. === total of missed / delayed half-staff orders: 4.5 days during 60 day study (all were 1/2 days missed) ]
