Unum is a civic literacy app that makes it easy to follow U.S. legislation and the members of Congress who represent you. Track legislation that matters to you: Browse bills from the current congressional session, filter by policy area, and follow the ones you care about. See exactly how your representatives voted, who cosponsored a bill, and where it stands in the legislative process — from introduction to becoming law. Follow your representatives: Browse all 538 members of Congress. View each official's sponsored bills, committee assignments, policy focus areas, and contact information. Add officials to your lists to track their activity. Build your own civic feed: Create custom lists of bills and officials. Your lists become a personalized feed that surfaces updates whenever something changes — a new vote, a bill advancing through committee, or a new action from an official you follow. Stay informed with notifications: Opt into push notifications for bills and officials you follow, by policy area, or by state delegation. Never miss a significant vote or legislative update. Civics reference built in: New to how Congress works? Unum includes a built-in civics guide covering how a bill becomes a law, how to read legislation, how to contact your representative, and more. Data sourced from the Congress.gov API (api.congress.gov), provided by the Library of Congress. Unum is an independent civic education app built by Unum Initiative. It is not affiliated with, endorsed by, or representing any government entity. Unum is free, contains no ads, and never sells your data.

Verdict
The clearest difference is in-app purchases: Unum at none against SpecimenPro's 1. Unum also leads on ratings volume (21 vs 1) and iOS requirement (15.1 vs 18.6). SpecimenPro's advantage is update cadence (every 3 days vs fortnightly). On price, rating, review sentiment and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. SpecimenPro sells 1 one-off in-app purchase. Unum asks for nothing beyond the download.
On the App Store both sit at effectively the same score — 5.0 for SpecimenPro against 5.0 for Unum. That said, the two scores are not equally well evidenced: Unum has 21 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
SpecimenPro ships an update every 3 days, Unum fortnightly. The most recent releases landed on October 28, 2026 and November 9, 2026 respectively.
