As answered by people managing FullStackToolkit and Follicle.
Follicle's answer:
The primary audience is any person that is losing their hair.
Follicle's answer:
Most hair care apps either use AI to analyse photos or track routines without photos, Follicle does all of this. With a AI features, journals, and a private photo gallery, you can keep all of your hair progress in one place.
The biggest differentiator is Ghost Overlay. With this feature, you can take consistent photos every time, which makes comparing photos and monitoring changes much easier.
Follicle's answer:
Follicle has an amalgamation of features that competitors can't compete with. AI, securely stored photos, comparison features, and journals, all in one place.
Ghost Overlay is unique to follicle too, and encourages consistent photo-taking which makes comparing progress (and generating better AI reports) much easier.
Follicle's answer:
I got frustrated with being unable to take consistent photos during my own hair journey, which is where the ghost overlay idea came from. Also, using random camera roll photos and documenting my progress in a notes app just wasn't efficient. Before Follicle, there wasn't an app dedicated to this.
Follicle's answer:
Android studio, ChatGPT, Figma, python (for building custom machine learning models)
