A pentimento is the trace of an earlier idea that shows through a finished painting. A finished painting buries its own history — the underdrawing, the dead layer, the glaze that changed everything. Pentimento keeps that record. A private studio companion for painters and realist artists. Document the process Add dated progress photos to each piece and label the stage — underdrawing, imprimatura, dead layer, block-in, glazing, varnish. Every painting keeps a full timeline, and a progress reel plays the stages back as a short video. Catalogue your work Record title, kind, medium, support, dimensions, and notes for each piece. Group work into collections — a show, a series, a gallery's stock, a collector's set. Keep the records Track status from in-progress to at-gallery, on consignment, or sold. Keep consignment records with the gallery, commission rate, and dates. Hold sale provenance — price, buyer, gallery, and commission — so a piece's history is never lost. Showcase a finished piece Present any work in a drawn frame on a choice of textured walls, and share the image. Light and dark appearance. Alternate app icons. Everything is stored on your device — no account, no cloud, no sign-in. Private by default. Free to use with one project and one collection. Pentimento Unlimited removes the limits with a single one-time purchase of $9.99 — not a subscription. Your art, in progress.

Verdict
The clearest difference is update cadence: Pentimento at every 2 days against ClayLab's every 2 months. Pentimento also leads on rating (5.0 vs 4.6). ClayLab's advantage is ratings volume (369 vs 1) and iOS requirement (16.4 vs 26.4). On price, ads, in-app purchases and monetization model there is nothing between them.
