Not OP, but have a look at [0]. It’s not great, but good enough. I regularly use it for App Store screenshots with captions and text. [0] https://theapplaunchpad.com/. - Source: Hacker News / about 1 year ago

For an advanced approach that includes localizations of your text and a ton of included resources to build your designs off of, there is AppLaunchPad (which has both a screenshot version and a mockup version with free and pay-by-the-month options), there is Vernissage which has a free and a pretty cheap pro version, and then there's App-Mockup which is free web-app. Source: almost 2 years ago

Https://stonksfolio.com I started it to track my all my investment accounts in one place and a couple of years ago decided to open it up to the public.
