Ace applies from its inbox. CoBlack applies from yours

What Ace does

Ace is a mobile job search app. It ships on iOS and Android only, and its site offers no other way in. Its homepage says it plainly: “Basically, Tinder for jobs.” You swipe on matched roles.

After the swipe, Ace generates a tailored CV and cover letter for the role, optimized for ATS, and applies on the company’s website. Version 1.2.3 shipped on 2 September 2026.

The homepage claims 8 million new roles a month, up to 3 times more interviews, and a 15 percent higher average salary. Ace’s Terms of Use add a line few companies publish: “Any examples or statistics are estimates based on internal testing, they are illustrative and are not promises.” That is fair, and it is uncommon.

How Ace handles the inbox

Many ATS platforms require an account and a verification code to complete an application. Ace built a specific answer. Section 4 of its Terms of Use: “Ace may create accounts on certain ATS platforms and generate a dedicated application inbox for MFA and application follow-ups.”

The privacy policy (section 7.2) goes further. “Your application inbox address is used as the primary email entered in job applications, in order to handle account creation/verification and to receive follow-up emails.” Important follow-ups are forwarded to the address you signed up with.

So the employer receives an address Ace generated. That is a deliberate engineering choice for a real problem. It also means the reply address on your application is not the one you check yourself.

What the reviews say

Ace holds 4.7 out of 5 from 152 US App Store ratings as of 4 September 2026, a good score. Google Play shows 4.3 from 25 ratings and 100+ installs.

A five-star review from 3 August 2026 notes that “bugs get fixed fast and new improvements ship constantly.” The shipping record agrees.

The inbox is noticeable in use. A two-star review from 9 July 2026 puts it this way: “gives employer an email that won’t go directly to you.” That is the documented mechanism, from the user’s side.

One disclosure. CoBlack competes in this market and publishes this article. Check it against its sources as you would check Ace’s.

Where CoBlack stands

CoBlack submits the email on your profile. It is part of the gate CoBlack checks before Auto Apply can be switched on, and the employer replies to it directly. CoBlack creates no accounts for you and no separate inbox.

Auto Apply is fully autonomous and server-side. It runs while you are offline, with no per-job review step. Ace submits without showing you every field either, by its own terms, though each application starts with your swipe. Per-job tailoring is a tie: Auto Resume builds a fresh resume for every opening from your Capability Map.

When a Greenhouse application hits a verification code wall or bot detection, it goes to a support queue and a human agent completes it by hand.

The limits are real. Greenhouse is CoBlack’s only confirmed submission surface today, covering roughly 80 percent of the job bank, with Ashby and Lever in progress. CoBlack has no standalone cover letter builder, and drafts one only when an employer asks for it. It has no native mobile app. CoBlack runs on the web, with a touch layout for phones since 26 August 2026, so Ace’s native apps are an advantage Ace holds. Both companies apply on employer and ATS pages rather than public job boards, which is the same instinct on both sides. CoBlack holds no interview-rate or salary data of its own and claims no better outcome.

Plans run from Point at $0 a month with 8 applications, to Vector at $19.99 with 200, to Matrix at $39.99 with 400.

The person each tool fits

Ace fits someone who wants the whole search to live on their phone. Swipe, and a tailored CV and cover letter go out for that role. Ace serves that person well.

The same person at CoBlack gets a fresh resume per opening and every employer reply in their own inbox. They give up the native app, the standalone cover letter, and breadth beyond Greenhouse for now.

The choice on the table is which address the employer writes back to.
