Is iStudiez dead?

I've been using iStudiez on both iOS and Mac for 4-5 years and it's been fantastic. I've tried myHomework, MyStudyLife, a few others I don't remember the name of, but they don't really compare.

I didn't notice my payment method expired recently, updated it to a new card, but when I went to resubscribe to the annual plan it was.. broken? Image below, it looks the same on both iOS and the desktop app.

I can't check the company's twitter, but the facebook seems to be either dead or inactive. Emailing their support address gets radio silence. I can't feasibly use this app without Sync. Anyone having the same issue?

Edit: They responded! However, it's with... worse news.

After being on the market for almost 15 years, we have always aimed to provide our users with the best experience to meet their requirements. 

However, times change, and maintaining our app and services like synchronization has become increasingly difficult and expensive. 

As a result, we had to make the tough decision to stop renewing the subscription services. We have started with the annual subscription.

For those who have already purchased a subscription, it will remain active until it expires. Unfortunately, it won't be possible to renew the subscription after that.

Really sucks. They could charge double and I would sub. Have yet to find an app that does as much as this one. Any reccs? ;-;


Edit 2: Tried a few other apps (MyStudyLife, MyHomework, Things3, Power Planner, School Assistant, etc). Didn't bother with TickTick or Todoist, they're not what I'm looking for, but I've heard good things about both.

None did as much as iStudiez - except MSL, I guess, but they just put out an update that broke both the web and mobile app. Subjects was suggested in the comments but it's a fairly new app and seems to be pretty buggy atm.

Eventually settled on this Excel / Google Sheets template: reddit link 1 or reddit link 2 or google drive link or direct sheet link. It's really well put-together and I've just been making extra pages for instructors, clubs, etc. I'm planning to just make a separate copy of the sheet for every semester. And to visualize classes and get reminders I'm using Structured. Free version is great but if you have a lot of repeating events, pro is $15/year or $10/year if you're a student, worth it imo compared to the prices of other apps I've seen suggested. Best of luck out there, folks
