Why isn't every option on this list?

This page surfaces 12 alternatives ranked by blended score. Apps just outside the top-12 typically have lower feature similarity (under 40%), thinner listings (audit under 65), or have flagged review-quality issues. If you have a specific app in mind, check the full Google Workspace catalog for its profile.

How is the ranking built?

Three signals, weighted: feature similarity (45%) from N-gram match against Lumin PDF - Sign and Edit PDF Documents's feature signature, audit + rating (35%) blending listing quality with rolling 90-day rating, and review velocity (20%) tracking 30-day review additions normalized by category baseline. We don't accept paid placement and we publish the rules so you can audit them yourself.

When was this ranking last updated?

If a rating shifts more than 0.05★ overnight, that's a real change in the marketplace, not a model artifact.
