The short version

  • Only Lensa has a free tier, so it costs nothing to try first.
  • Each has a real cost: Lensa the underlying Stable Diffusion model was trained on images scraped from the internet, including copyrighted artwork, without direct consent from the original artists, and Lensa avatar outputs have been criticised for replicating identifiable artist styles without attribution or compensation.; NightCap it is iOS-only, so Android photographers cannot use it at all.
  • They diverge on capability: Lensa covers Magic Avatars, NightCap covers Manual exposure control.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Lensa

  • The underlying Stable Diffusion model was trained on images scraped from the internet, including copyrighted artwork, without direct consent from the original artists, and Lensa avatar outputs have been criticised for replicating identifiable artist styles without attribution or compensation.
  • Users and journalists reported the Magic Avatars feature generating sexualised images from ordinary selfies, including reported cases involving photos of minors, without the user requesting that style, raising documented concerns about model behaviour and safeguards.
  • Magic Avatars typically requires a separate one-time purchase on top of any Pro subscription, so the total cost of trying the feature is not covered by a single subscription fee alone.
  • The free trial converts automatically into a paid recurring subscription unless cancelled beforehand, following the same pattern of complaints about unexpected charges seen across comparable apps in this category.
  • Generating avatars requires uploading a set of personal selfies for AI processing; Prisma Labs states these are deleted after processing and not used for further model training, but this relies on the company's own stated policy rather than independently verifiable proof.

NightCap

  • It is iOS-only, so Android photographers cannot use it at all.
  • Results are still limited by the physical sensor size and aperture of an iPhone, so it cannot match a dedicated mirrorless camera for astrophotography.
  • It requires a tripod or other stabilisation for most of its long-exposure modes, which is an extra cost and inconvenience beyond the app itself.
  • Its manual controls have a learning curve for someone used to a fully automatic point-and-shoot camera app.
  • As a niche app from a small developer, update cadence and long-term support are less predictable than a major platform vendor camera app.
