A LOCAL SERVICES MARKETPLACE THAT DOESN'T PUNISH EITHER SIDE. Most home-services apps charge pros a subscription AND a per-lead fee, then pass that cost to you in inflated quotes. When customers ghost, pros eat the loss. When pros ghost, customers start over. Everybody loses except the platform. WorkerKey fixes both sides of that broken deal. WHAT YOU GET AS A CUSTOMER • Free to use, always — no subscription, no booking fee • Post a job in under 60 seconds • Real quotes from verified local pros, not range-bait • See reviews, credentials, and insurance before you book • Message pros directly inside the app • No-ghost guarantee protects you too — if a pro disappears, we credit you a free promoted re-post WHY PROS SHOW UP HONEST HERE • They pay per qualified lead, not a monthly subscription • If you ghost them within 48 hours, their lead fee is refunded • Lead price scales with the size of the job — not the pro's tenure • Service-tailored questions mean they quote real work, not guesses That math changes the quote you get. Pros aren't padding prices to cover dead leads. INSIDE THE APP HOME Post a new job, pick from popular service categories, and jump back into anything in progress. EXPLORE Browse 100+ categories — plumbing, electrical, HVAC, cleaning, landscaping, handyman, moving, painting, appliance repair, and creative work like logo and photography. Find the right pro for the actual job. MY JOBS Every job you've posted, the quotes you've received, and the status of each one — all in one place. No digging through email threads. MESSAGES Talk to pros directly. Share photos, clarify scope, and lock in the quote without ever leaving the app. HONEST PRICING WorkerKey is free for customers. Pros pay a per-lead fee that ranges from about $8 to $22 depending on job size — and they get it refunded if you ghost them in the first 48 hours. We don't charge pros to be verified, we don't sell "premium tier" badges, and we don't punish either side when something falls through. That's it. No upsell, no surprise booking fee, no inflated "service charge" at the end. WHAT WORKERKEY IS GOOD FOR • Home repair you keep putting off • Recurring services like cleaning, lawn care, and pool maintenance • One-off projects like a logo, a photo shoot, or a moving day • Anything where you'd rather get real quotes than chase voicemails This iOS app is for the customer side — posting jobs and hiring pros. The pro app is shipping separately. Download WorkerKey, post your first job in 60 seconds, and see what fair pricing on both sides feels like. -- Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://www.workerkey.com/privacy

Verdict
The clearest difference is update cadence: WorkerKey at every 4 days against Kidde's every 2 months. Kidde's advantage is device support (3 vs 1) and iOS requirement (14.0 vs 16.4). On price, ads and in-app purchases there is nothing between them.
