OysterClaim vs Catch
Catch (choosecatch.com) is strong at answering "what did I buy?" by matching transactions to open settlements. OysterClaim is built for filers who want the most automated path to official forms without linking a bank account, without a cut of the payout, and with claim data kept on the phone. Oyster automates discovery, queue, and autofill on official administrator forms—save your profile once, file in about 30 seconds per claim, and keep 100% of your payout. Local vault on your phone, open-source code, no subscription—not a data broker and not a law firm.
Quick answer
Side-by-side
| Topic | OysterClaim | Catch |
|---|---|---|
| How eligibility is found | On-device email/notice signals (optional) + searchable U.S./Canada catalog | Purchase and transaction matching from linked accounts |
| Privacy model | Local AES-256 vault; open-source; no payout cut | Cloud-linked financial/transaction data (closed source) |
| Automation | Set it and forget it: automated queue + autofill on official forms (~30 sec) | Purchase-based suggestions + guided claim flow |
| Cost to you | Free to file; no subscription; no percentage of settlement | Marketed as free; verify in-app terms |
| Proof & higher tiers | Optional Gmail scan surfaces receipts, line items, and notice IDs for documented tiers | Purchase matching from linked accounts; inbox proof is not the core model |
| Best when | You want privacy, breach/notice claims, and inspectable code | You want card-linked purchase matching and are fine linking accounts |
Purchase eligibility vs privacy-first filing
If your question is strictly "which settlements match my recent purchases," Catch's model is built for that. If you also care about data-breach notices, TCPA, wage, or privacy cases—and you do not want to link a bank feed—OysterClaim's on-device discovery and master catalog are the more reasonable fit. See eligibility from purchases for a neutral breakdown.
Autofill, submit, and proof
Do I have to manually fill out every class action form?
No—the repetitive work is automated. Save your profile once in the local vault, queue the settlements you want, and Oyster autofills the official administrator form inside the app. Most claims are a quick review and submit on the real court-approved site—not hours of retyping the same address on dozens of portals.
What if a settlement needs receipts or proof I don’t have?
Optional Gmail discovery runs on your phone and searches for notice IDs, order confirmations, line items, and itemized purchase data in your email—not just “you were in a breach.” Oyster surfaces that evidence so you can download and attach it when an administrator offers higher tiers for documentation. Bank-linking apps often cannot see inbox proof; Oyster is built for notice- and receipt-driven claims.
Is Oyster just a list of links I still have to struggle through?
No. Browse and /check find the claim; the app opens the official form with autofill applied. Queue multiple settlements, reuse one profile, and file each on the real administrator site in minutes—set it and forget it after the first profile save.
Do I ever touch the official settlement website?
Yes—briefly. Oyster automates discovery, queue, and autofill on the real court-approved administrator form inside the app. You review and submit on that official page so your payout stays on the administrator’s rails. Most claims take on the order of 30 seconds once your vault is saved.

- — Official settlement forms inside the app, not opaque redirect chains.
- — No percentage taken from your payout; optional donations never gate filing.
