Claim Forge

A warranty is only worth what you can prove and what you can still claim. ClaimForge keeps both: a record of what you own and what its cover actually says, and a working process for the day something stops working. File a purchase with its store, price, category and warranty term. The warranty preset comes from your own table of defaults per category, and the expiry date is calculated in front of you as you fill the form. Add the serial number, the order code, and - just as important - a note about where the proof is kept, whether that is an email thread or a drawer. From there the app watches the clock. The vault shows how much cover is left on every item, flags the ones with no receipt saved, and marks anything close to expiry. The deadline board groups items by horizon or lays them out on a 24-month timeline, and keeps a separate, harsher counter for return windows that are measured in days rather than months. When something breaks, open a case against the item. Choose what you are asking for, describe the fault, and start an escalation programme with dated tasks: gather the proof, write the first message, follow up, ask for a reference number, escalate to the manufacturer, send a final notice. Every reply, phone call, chat and store visit goes into one correspondence trail, and closing the case records the outcome, the amount recovered and how many days it took. The built-in assistant helps with the writing. It drafts a claim letter in the tone, channel, language and length you pick, analyses warranty terms or a seller's reply that you paste in, pulls the fields out of an order confirmation so a new item can be filed in seconds, and answers questions about the process. What you can do: - Store purchases with warranty term, extended cover, return window, serial number and receipt status - Search by name, brand, store, serial or order number, and sort by expiry, price or warranty left - Filter instantly with four live summary tiles and eleven category chips - Track a proof checklist per item and keep dated service notes - Group deadlines by horizon or read them on a 24-month expiry timeline - Keep a hard day counter on open return windows - Open cases for repair, replacement, refund, return or dead-on-arrival goods - Run four escalation programmes with day-by-day tasks and progress - Log every message, call and visit in a single dated trail per case - Draft claim letters and analyse warranty terms with the optional assistant - Read a 12-card playbook on proof, writing, escalation and chargebacks - Earn ranks and badges as the vault and the case record grow - Get local reminders before cover ends and before a return window closes Everything you file is kept in the app's own storage on your device. There is no account and no tracking. The assistant is the only online feature: it asks for your agreement first, and a single switch in Settings decides whether item details are attached to a request. ClaimForge provides templates and general information, not legal advice. Consumer rules differ between countries and sellers.

Verdict
The clearest difference is in-app purchases: Claim Forge at none against PercentLab's 2. Claim Forge also leads on ads (none vs shown). PercentLab's advantage is update cadence (every 4 days vs every 10 days). On price, device support and iOS requirement there is nothing between them.
