Thank you so much! I hope it serves you well.
We're a very lean company (everyone works remotely).
Due to the specific nature of iStat Menus, we need to do testing on each model of hardware. This sometimes means we borrow friends' Macs, but often it means buying and reselling Macs.
Is ~$10 every two years (~$5 a year) a lot for something you might use every day? That decision is entirely up to you. We want to make sure iStat Menus is the best app of its kind, and that means constant maintenance. We really don't mind if you skip major versions (~$2.50 a year).
If we were on the Mac App Store, we couldn't offer update pricing at all. We also couldn't offer a trial. And we couldn't offer refunds. We're doing everything we can to make sure the only people who buy our software are those who like it.
I completely understand why you may be upset, but please understand it was a huge amount of work that went into this update. And please understand that the update is entirely your choice.
We're also offering free updates for anyone who purchased on or after 15 July 2014.
All we want is to ensure iStat Menus can continue to serve those who use it well. That means every couple of years, there may be a paid update available.
I bought version 4 last year, and bought version 5 today. I really like it.
