I need to second what the other posters wrote.
And I am disappointed, to say the least.
I am NOT going to subscribe to ANY software EVER!
And i think many see it this way.
I thought that Devon Technologies were using a licensing model that is often used on desktop and now more and more on mobile: Buy the App, get one year of updates and new features, after that you only get basic security updates, bugfixes and required updates (for OS updates, for example) but no new features - until you decide that you want such a new feature and buy another year of updates and all features that got added in-between.
I have no problem with such a license!
And it is even so that I researched this topic because I wanted to support Devon Technologies and buy a DT 4 Standard edition.
I have no need for the new features of version 4 and just wanted to give my part to this.
And I also have no need for the server or pro editions.
But then I noticed the potential problems with the mobile App.
I even thought about getting the DT4 Pro edition, so that my mobile devices could get a license too - but that does not work, as long as I don’t buy the update every year!
And THAT is, by definition, a subscription!
Basically, that is “Augenwischerei” as we say in Germany, it’s a trap as DTTG in free mode is completely useless - I want to add stuff on the mobile devices that get’s synced.
I see no way to continue using DT and DTTG with the new license models!
I either need a yearly DT Pro or Server subscription, or DT Standard and then a DTTG subscription.
That is not what I want and can or will do.
I am sorry.
To be honest, there would be an easy fix!
Apply the same license type I mentioned above to DTTG too!
Let me buy that App and be happy with it for 10 or 20 years without new cost - as long as I don’t need or like a new feature which makes me buy another year.
And just to tell that:
Other Apps like Working Copy or Loopy Pro (and lots of others) use the same model!
And I bought the updates every year! Just because I liked the new features!
I hope I could get my point over clear enough.
I would give more details and idea about this, if I had the impression that you possible would change the license model for the mobile App, but from what I saw, this is not very likely. Sadly.
Instead, I start to research alternatives to DT / DTTG.
Adding stuff could be done with Syncthing and on the Mac, there are some alternatives to manage documents. This would loose a basic client on iOS / iPadOS but as I said, I mostly only add stuff on the mobile devices.
I am disappointed to learn this, sorry.
