Photodiva, it's amazing for portrait shots. Source: 6 months ago

Another thing that I find handy is Photodiva, it's a portrait software that handles pictures just as good as Photoshop or Photoworks do, but it's just exceptionally good for quick editing of portraits. Bonus points are that it's free and super beginner friendly (in fact, that's where I started from). Source: 8 months ago

Photoworks for photo editing. I also have Photodiva, it's a portrait editor and I don't use it a lot, but it's free so why not lol. Source: 11 months ago

Haven might be what you are looking for. It can activate sound and video recording upon noise, light and vibration. It is in the IzzyOnDroid Repo or has its own repo. Check the project page: Https://guardianproject.github.io/haven. Source: about 1 year ago

Haven is open source. Last updated 2019, but works. https://guardianproject.github.io/haven/. - Source: Hacker News / over 1 year ago

You could retire it to a personal surveillance camera with haven (needs a sim for registration though). With root, you could even set a charging limit so the battery doesn't die. Source: about 2 years ago

For budget option, you can install Haven on an old phone and it would record/report audio, visual and movement you need to monitor. Source: over 2 years ago
