Horrid Update

I have used this app for years and years. Loved it. Even paid for the pro version it was so long ago I can’t even remember how much it cost but it was responsible and the app was so great. Now the app not only looks horrible and has become difficult to you use, you also want £5 A MONTH!!!!! Never is any period app ever been or will be, worth that kind of money. EVER. We are logging a period, not a lot more. It’s gone from the best period app to the worst with this disgusting money grabbing update. Fitbit now offer the same in their app for free, yes you have to own one of their watches (which I do) but at least it’s a physical object I get years of value from. What on earth will me handing over £5 a month to you bring to me? Where is the value?? Answer... There is none. A period calendar can never be worth a subscription, ever, well unless you are sending me sanitary products of my choice each month or access to a streaming service... Awful just plain awful.

10 years of data has been rendered useless

I have been faithfully using this app for 10 years and until the latest update, it was brilliant. However, during the update my data has not migrated accurately. Which has all but rendered the information useless.

I wish I had not placed so much trust in this app and I feel pretty stupid for doing so. However, had I been keeping a hard copy of the data elsewhere, I would have had no reason to use this app at all. For the first couple of years I did write it elsewhere, but I guess I became complacent and trusted the app mistakenly.

I emailed Winkpass, urging them to help resolve my issues. Appealing to them to help, due to the medical information which they held on my behalf and that it was important information pertaining to my health over a decade, which I now have no knowledge of. I would have to make many guesses about the data and when there are serious health problems concerned, that just isn’t good enough. I have had no response to my email, not to answer any questions, address/fix the issue or even to acknowledge receipt.

As I said, more fool me for trusting the app with my data. However, I did want to express my concerns for anyone else potentially considering using this app.

Horrible ‘upgrade’

Been using this app for years without any issues until this new version suddenly appeared. It looks like it wants to be Fitbit when it grows up, which is not something I want or need. The data migration has apparently been severely messed up, and awesomely, if I want to extract the last six years of my own (personal and sensitive by the definition of the data protection act, incidentally) data I will seemingly have to pay a subscription fee for the privilege. Assuming my data hasn’t been messed up entirely in the process of this cack-handed circus sideshow of an update.

Or, as I have spent some time this morning doing, I can sit down with a sheet of scrap paper and a pen and manually transcribe the lot.

I’m done with this app. Sorry, it’s not me, it’s you and your lack of communication and customer focus.
