User reviews

Can’t purchase lifetime license

Seems very promising! I heard about this on the developer’s YT channel in a video he did about a unique travel setup for the Komodo-X. However, whenever I click the lifetime access button, I’m met with a “Purchase Error” dialogue window. Hope this gets sorted out so I can test it out properly—would be useful for the environments where I primarily shoot.

Response from developer

Fixed! Apologies, it turns out navigating the app review process and working out "non-consumable in-app purchases" is a different skill set to actual app development. Whodathunk it.

Lifetime option does not work

The lifetime subscription option says it can’t contact the App Store, even though clicking the subscription option pops up the payment screen as expected.

Since there is no way to access the app without paying and since I don’t need another subscription, this renders the app fully useless for me.

FAQ

What is ColourTemp's primary function?

Does ColourTemp have ads?
