### 4/5 — Update

*2026-01-24*

I just updated the app and it got rid of all my data for the last month like what the heck?

Update fixed this issue

**Developer response:** Dear Amy,

I am so sorry about that! With version 1.1.0, I made it so you don’t have to log healthy days. Unfortunately, this introduced an issue that hides data from before this version. I’ve just pushed version 1.1.1 to the App Store that should fix this issue. 1.1.1 should be available within the next days. Once again, I am so sorry about this!
Please email me at hello@flowritesco.de if this issue persists beyond version 1.1.1. It would be great if you updated your review if this new version does fix your problem.
Best, Flo (solo developer)

### 2/5 — Have To Pay

*2026-01-09*

I am super tired of these apps that you think are going to be free for the most mundane minor things, but then you end up having to pay for them. For instance, in this app for the first two days, I was able to log whether or not I was feeling well or sick.. Today the third day it won’t let me log whether I’m healthy or sick. The only way it seems that I can do this is to pay for the app. There’s not enough that this app offers from what I can see to actually even consider paying for it. My opinion – don’t waste your time with it.

**Developer response:** Hey there,
thanks a ton for giving SickDays a try and leaving an honest review! With version 1.1.0 (and up), I’ve added several new charts to the app and made more features free. Logging symptoms is now free forever. I’d love for you to give the app a second chance - it’s a passion project I developed last summer.

Best, Flo
PS: If you have any questions, please write me an email at hello@flowritesco.de
