Electronic Signature is a market-leading productivity app that is free with in-app purchases.
With a 4.29/5 rating from 70 reviews, it delivers strong user satisfaction.

<!-- speakable-start -->
> **Bottom Line:** Electronic Signature serves basic capture needs, but the persistent ad-load and lack of updates erode user trust, so the developer should prioritize an ad-free UX or feature expansion to retain the user base.
<!-- speakable-end -->

**Best for:** Users requiring a simple, mobile-based tool to create and export handwritten signatures for digital documents.

<!-- section:pm-actions -->
### PM Action Plan (Next Best Moves)

- [ ] [PIVOT] Audit ad frequency because users report it as a barrier to smooth capture -> reduce churn.
<!-- /section:pm-actions -->

<!-- section:outlook -->
### Outlook: Stable

The signature-capture market is consolidating around tools that offer both handwriting and text-based font options. Electronic Signature's current maintenance-mode posture leaves it exposed to competitors that offer a more flexible document-signing experience.

- 🔴 The 26-month feature drought signals a maintenance-mode posture, which prevents the app from addressing user requests for text-based signature options.
