Sabotaged account

Paid for the app several years ago. Nothing but good things to say about it. Until September 9, 2023. My app suddenly disappeared. Removed from my Apple account. No longer appeared on my phone. Purchased the app again. And all of my calendar events suddenly reappeared. But everything I saved for repeated use was gone. Information I saved for several years. Now had to be re-entered. And at the cost of re-purchasing the app. I am out raged. But who cares right?

Response from developer

Hi, Did you really think this is something we did? I actually think you probably switched your Apple account, as you would not have been charged again by Apple on the same account, Apple is in control of all that. Or you switched between one of our other Extreme titles that you had updated. Sorry this happened to you, but I do not remember hearing from you on our technical support email to try to help.

Disappearing Event Issue

I never responded to the last Birdsoft developer response (thank you for that!), so I thought that I should finish off before any next steps. 😌

I took your points and appreciated almost all of them, although I do not know that it is fair to speak of my expectations for “all” apps. I just know that when I buy one I want it to continue to work. That is just the nature of being a client or consumer, and understandably so. However, I did understand what you were trying to convey. • I expect that you did send out the app update that you mentioned, but the version of Extreme Agenda I was using was the add-on that I purchased through Extreme Week (purple icon). So I did not receive an update there. • Anyway, since I really like that product I am happy to try out the Ultiplanner (sp?) and possibly purchase it. I just hope that this new app will allow me the same ability to display my engagements as icons (instead of words), and that the “Categories” will also sync across all my iOS devices along with the other data (which Extreme Planner just never did somehow). Looking forward to the experience!

There is an ongoing glitch with this calendar that occurs while you have a window open and are configuring an event for the first time (so it is not saved yet). Although the original version of this app did not have this issue, the window that opens when you are creating a new event is quite “bouncy.” By this I mean that the entire date configuration window display can be pulled downwards just by touching the screen and dragging your finger downwards a bit. Then when you let go, the window pops back up to the top of the screen like a rubber band. In the process, anything you entered into that window almost invariably gets erased and you are left with an empty default window. It is as if you had just opened a new event window and had not worked on it yet. So you have to create your event again from scratch. This is a problem not because you are going to intentionally pull downwards on the window while you work, but because it is so easy to do so accidentally. So you have to be so careful about how you touch the screen now and this is like tiptoeing with your fingers. As a user, this is uncomfortable and unnatural. • It occurs to me that perhaps this is what some users were referring to when they mentioned “disappearing events” in their reviews of this product. • I should note that this issue did appear to be fixed at some point two years ago but the problem returned again after a week or two. I just never said anything about it until now.

Thanks again for explaining the glitch, watch for it to be fixed in version 5.20 coming out very soon. Apple created that glitch by defaulting all screens to act in that way by default, thus changing how existing apps worked, which was not a great decision...

Latest Update Is A Big Improvement! 🎉

(6 March 2021): For the past year it has been really difficult to use the calendar, as it was unstable, and events got erased easily & unexpectedly. However, since the latest update, the app has been stabilized and greatly improved. You no longer need to be super careful and delicate when swiping through icons & options and setting up events. What a relief! 😅

I notice two remaining issues:

• The “...” section at the top of the screen, that used to take you to “Settings,” where you could create or remove categories, has disappeared. So not only can you not alter your categories, when you try to set up your color coding, the only choice it gives you is “Calendar.” The “Categories” section appears to be gone so you cannot set up your calendar display using categories (my preferred mode of display).

• The “Subject” Window, still lacks the + and - buttons that used to allow you to remove or make an entry to a list of events that you created (so that you could tap on one and quickly enter a subject for your event). I hope this is restored soon.

In the meantime, thanks for fixing the rest!

Update!!

Kalender stürzt ab, Februar 2021 lässt sich nicht öffnet.
Bitte um ein Update!!!

Support

Support gets back to you very quickly when you message them. Apples iOS updates may mess up the app but support helps you figure out how to fix it.

Thx

Leider sehr altbacken

Sorry, der Kalender sieht für mich sehr altbacken und nicht gut aus.
Was gar nicht geht ist, das bei der Eingabe der Adresse des Termins nicht auf geographische Daten zurück gegriffen wird.

Dies when used

First my calendar wouldn’t work on my iPad; it would blank out, then it started doing it on my iPhone 8! WTH!

Response from developer

We are looking into this, we weren't seeing this in beta testing but now have a couple ways to reproduce, so hopefully a fix is coming soon.

Even! with limited reminder sounds...

I like everything about this app except for the alerts/alarms/reminders. There's just one sound that goes off. There's nothing that tells what the alert sound is for. I end up having to go in to figure out what the alert sound was for. I have copious alarm and reminder sounds (from various apps) because my mind needs them. The state of the audio notifications doesn't keep me from using this calendar though. I thought it was amazing a few updates ago. And now even with updates it's only gotten better. The customizing capabilities is one of the big things for me since I have to look at every other hour. At one point there were only a few icons to choose from. Now the selection is very workable. You can set up to be reminded at multiple preset times. Make templates. Make lookups of places and people/destinations. It's nice to have different views to choose from. I won't list any more since it's in the app blurb. It is worth the $$ in my opinion.

Not Recommended

This all-in-one app (after in app purchase) is feature rich and allows under the hood customizations. The layout is professional and visually appealing. It includes a calendar, reminders, lists, contacts, and notes (limited).

Update: after multiple attempts to contact the developer were unsuccessful (app will not sync), this app has been downgraded to two stars. I'm now back to using Note HD (A note) which I recommend.

Doesn't work for me

Save your money, I found one for a third of the price that works a lot better. I can not get this one to sink between my two IPhones and my IPad. The tiny calendar automatically sinked the three together and was only $2.99. I could not get the app to work, I wish that I had spent more time checking into this app and saved the $12.99. Deleting the app and reinstalling tiny calendar.....

Fix can't create new calendar on iPad mini.

Please fix

Be warned!

Useless, non existent support, and the photo upload function only does not work.
Save your money.

Love it

So convenient, I no longer carry an agenda. It syncs to my iPad also.

Useful

Very useful, but it keeps adding the number of appointments and that is annoying. Unable to erase or clear past appointments.

Très utile

No 1

We can't remove a full calendar

The user in the other review must have filtered his calendar to hide it, it will not allow you to remove an entire calendar. And it is a normal calendar app so there isn't anything difficult about it...

Don't buy it

Horrible . Erased my entire month just a few minutes after putting it all in. It also is not used friendly. Even my very skilled computer friend was annoyed with it while trying to use it. Don't waste your money like I did.

Wie für mich gemacht, umfassende und schlüssiges Konzept

Awesome calendar

Does everything I could expect. Very pleased.
