Would pay for an application with modern topographic maps. Installed with the Soviet military, but they are already very outdated.
And modern, alas, only in dreams, because this is an information resource inaccessible to a mere mortal.
I'm willing to pay for the graph. editor, if he is really useful in his work, and his development company does not show that they generally do not give a damn about me. I've already bought a couple. I'm willing to pay for a good FTP client. One already bought a desktop one, one bought for an iPad. I want to buy two more desktop ones, but one costs more than 1000 rubles, this is a lot for me, and the other is so wildly buggy that I won't use it. I'm ready to buy an environment for writing texts with additional features for writers, and I have already bought two times: Scrivener desktop and Scrivener for iPhone + iPad. Just out of admiration. I'm going to buy a new version of the desktop, but it's expensive, I haven't got it yet. I'm ready to buy some games if I read an interesting review or feel that they are very atmospheric. The option when half of the game is played for free, and you have to pay for the other. On average, I am ready to pay 99-250 rubles for a mobile game, for a larger-scale or desktop one within 600 rubles a thousand, but without donation and without a subscription. I am ready to buy a good quote manager if he has a free version to try. I bought one. Glitchy, the fix was never released. But handy. I'm willing to buy a good notebook with extra features if it has a free version with enough features to feel like I need it. I'm going to buy Sublime Text because it's great and I I like his trial policy. I am ready to buy a really good mailer, and even bought a couple.
I am ready to buy all this for a certain amount, once. And maybe send additional donation to support the author. But I am NOT READY to pay for a subscription, even if it is inexpensive.
For which I am ready to subscribe: 1. a server for the site and a domain to it, 2. perhaps in the future, a radio like Apple Music, but for now which is not, 3. maybe in the future iCloud, but not yet. As you can see, this is either a lot of space on their disks, or a non-stop service. And I'm not ready to pay for a damn notebook or a damn graphic editor by subscription.
