In-App statistics update too late #533
Comments
Dear @whiskey, Thank you for your contribution. As far as we know, yesterday February 26, there was actually a delay in showing the updated numbers. Please, stand by, we will come back to you. Best wishes, DS Corona-Warn-App Open Source Team |
Would have made more sense… I'm too biased which repositories I use :) |
@whiskey @Ein-Tim Thanks. Internal Tracking ID: EXPOSUREAPP-5445 |
See corona-warn-app/cwa-server#1223 where it was confirmed that the cwa-server just has a reformatting and pass-through function as far as RKI infection statistics is concerned. This repository (https://github.com/corona-warn-app/cwa-documentation) is the best one for functional problems affecting both the iOS and the Android app. |

All, Unfortunately, there is no real "latest time to expect statistics" - at least not of my knowledge. So, yes, as multiple data sources are combined and those are not always available/up-to-date at the same time with the same level of data quality, the complexity for the CWA-feeding background process is much higher than scanning one single data pot. Subsequently, the required effort for presentation with respect to time and data quality is higher. As those in-app statistics shall support users and help them adjust their own behavior accordingly, we consider data accuracy and consistency are key. Still, we are working on continuous improvements and acceleration of the process. |
@GisoSchroederSAP Today, Wednesday, March 3, 2021 at 08:00 all RKI statistics values shown by the (Android) app are consistent and up-to-date with other RKI information sources available online (Dashboard and Fallzahlen). 👍 |
Today, Thursday, March 18, 2021 16:20 all values in the app have been updated except the 7-Day Incidence, which is still showing the value 86.2: the same as it showed yesterday. The new value of 90 was published by RKI to Fallzahlen.html this morning at 09:40 and the value of 90.4 is also shown in RKI's Fallzahlen_Kum_Tab.xlsx Excel file (in cell BL_7-Tage-Inzidenz'!LG20). So I'm wondering what happened to the data feed for the 7-Day Incidence to the CWA app which I would expect to show 90.4 right now, instead of 86.2. |
@MikeMcC399 Indeed, the values were updated late today. Will try to get info about the 90.4 / 86.2 discrepancy. |
I can confirm: 8:35 p.m. The value of the 7-day Incidence is still not yet updated. |
Update: I'm going to ask tomorrow morning, if there is a way to indicate early, when there is an issue that prevents an in-time update of the statistics. Someone must be able to have transparency on the process. |
@GisoSchroederSAP Even the official PDF reported which is published every evening has the value 90. |
Let me share one more fact:
There a lot of "if" conditions, aren't there? Does this help? |
As of now, all statistics are up to date. |
@GisoSchroederSAP Did you find out why the value 7-day Incidence 90.4 was not published during the working day yesterday, March 18, 2021?
Agreed. Today, Friday, March 19, 2021, went much more smoothly. Today's 7-day Incidence is 95.6 and this is showing in the app. The site COVID-19: Fallzahlen in Deutschland und weltweit was updated today at 07:50 and Robert Koch-Institut: COVID-19 Dashboard showed today's data even earlier (it is currently showing "Letzte Aktualisierung: 19.03.2021, 09:06 Uhr, although that was not the first update of today). |
Did you learn any more about the reasons for past problems? The data in the app seems to be getting updated reliably the last days. Are you monitoring this automatically? |
I'm validating the content/values from time to time, still confident about correctness of the calculation. |
The statistics seem to get updated regularly and timely, so perhaps this issue #533 (In-App statistics update too late) can now be closed?
Is this action still to-do or has it been abandoned. |
I had another talk with RKI about the translation of statistic tiles (round four) and hopefully can publish the German version soon. |
Actually, as of now, the statistics in the app were not updated, but maybe I'm just a little bit too early awake today? 😅 Edit 07:30h: Still no update here, normally the app would show the statistics from yesterday. |
From my point of view, if the app updates by 08:00 on 95% of days I would be satisfied, however I realize that is just my definition of a Service Level Objective, which may not satisfy other people's expectations. It is currently 07:53 on Thursday, July 8, 2021 and all four stats tiles have been updated. |
Yes, confirmed. Today at 7:16 I got notification of a data chain disruption, at 7:52 I got the solution confirmed. |
Hi @MikeMcC399 and communty! Shall we close this one, or shall we keep open as a channel for updates by @GisoSchroederSAP regarding temporary "hick-ups" ? |
@dsarkar |
Noted. Hereby we close this issue. Will be reopened if necessary. Thanks everybody. Corona-Warn-App Open Source Team |
The alternate source of most data is: The Dashboard on https://corona.rki.de/ which covers everything except the 7-Day R Value. The "7-Tage-R-Wert" is published on the previous evening in the daily report on https://www.rki.de/DE/Content/InfAZ/N/Neuartiges_Coronavirus/Situationsberichte/Gesamt.html and in my experience this is the easiest place to pull this value. Otherwise RKI references this value on https://www.rki.de/DE/Content/InfAZ/N/Neuartiges_Coronavirus/Projekte_RKI/Nowcasting.html and publishes to https://github.com/robert-koch-institut/SARS-CoV-2-Nowcasting_und_-R-Schaetzung/blob/main/Nowcast_R_aktuell.csv. Note that the 7-Day R Value is continually revised, so it may be difficult to follow. |
Reading the OP of @whiskey again, I don't think that's really fixed. If the statistics always update at ca. 8:00h, this is 2h later than e.g. DLF announces the latest numbers. Could @GisoSchroederSAP comment if it's impossible for the CWA-Team to also have the figures updated as early as radio stations announce them or if this would theoretically be possible. Anyways, as long as we have regular updates, that's fine for me. |
Just a comment on the comparison with local radio stations and regional newspapers/websites.
This service of collecting, storing, clustering, checking/validating starts at 5 a.m. is usually finished between 6. a.m. and 7 a.m. If not, we become informed and can safely communicate. Cheers, Giso |
Thank you for the clarification. As said, this is fine for me and I appreciate the efforts of the CWA (analytics) team here. Really nice! Seems like it's okay to have this issue closed. |

Original post
First the basics:
Avoid duplicates
Technical details
Describe the bug
The in app statistics are great but updated too slowly. How can it be that DLF announces the latest numbers at 6 in the morning and the app still shows at 08:00 the stats from the previous day? Please update earlier, you have the 'direct line' to the RKI.
Steps to reproduce the issue
Expected behaviour
Numbers in the app are updated to the latest statistics.
Possible Fix
Only Server sided. No need to adjust the app code.
