RenoJira and Obra both start from the same observation: contractors don't know what a job cost until it's over. They answer it for different people. RenoJira answers it for the contractor holding the phone. Obra answers it for the contractor whose crew holds the receipts.
Where the two products actually differ
RenoJira is a single-operator app. You photograph the receipt, it reads the total, you log it against the job, and the app shows spend against the quote. That's a complete loop for one person, and it's free, which for a solo remodeler is the whole argument.
Obra assumes there are more people than phones with the app. A foreman sends a receipt to a WhatsApp number from the WhatsApp they already use; Obra answers in their language, reads it, and files a draft on the right job. A reviewer confirms it. The foreman never sees the contract value or the margin, and never needed an account on the books. The project shows recorded cost, cash collected and an expected final cost that moves with every confirmation.
The receipts problem, again
Every comparison on this site comes back to the same thing, because every job costing failure does. The margin report is only as true as what reached it. A free app that only the owner uses is accurate about the owner's receipts. The crew's receipts, on most jobs the larger share, still travel by text and still get lost. Obra's WhatsApp channel and submitter role exist for that share; the bilingual crew guide walks through a week of it.
What RenoJira does that Obra doesn't
Quotes with e-signature from the same app, and a native app store presence. Obra doesn't estimate or quote, and installs from the browser as a progressive web app instead of from a store. If quoting from your phone is the feature you'd use daily, RenoJira has it and Obra doesn't.
Price, plainly
RenoJira is free. Obra is free for one active project and $12 per user per month after that; a crew of three pays $36. The honest comparison isn't $0 against $36. It's $36 against the receipts that never make it into a one-person app, and on most crews that's more than $36 a week.
