People searching in Spanish for an app to control job expenses will find Obrahub and Obra in the same results, and the names invite the mix-up. They are different products for different countries, and this page exists so nobody buys the wrong one.
What Obrahub is
A field app for the independent contractor, on iPhone and iPad, in Spanish. You build a quote from your own catalog, it becomes a PDF with your logo, and you send it to the client over WhatsApp. If the client approves, one tap turns it into a project. Expenses and client payments are logged against that project and the app shows the running profit, with alerts when a project runs over budget. It adds photos and videos by project, technical reports with a digital client sign-off, task lists, GPS on each project, and a toolbox of calculators for concrete, masonry, slabs, paint, tile and partitions, plus an AR measuring tool. Its calculators cite Chilean standards and its screenshots show pesos. The free plan covers a few projects; the single-user upgrade is cheap; a multi-user tier with roles and web access sits above.
What Obra is
The ledger for each job, for a crew in the United States. Receipts come in from the crew over WhatsApp, in English or Spanish, and the office confirms each one to a project and a category. Every project shows what it has collected, what it has cost and where it is expected to land. Change orders adjust the contract without erasing the original. It runs in the browser on any phone, Android included, installs to the home screen, and exports everything as CSV. It does not quote, and it has no calculators.
The WhatsApp confusion
Both mention WhatsApp on the front page and mean opposite things by it. In Obrahub, WhatsApp is the way a quote leaves: the PDF goes out to the client. In Obra, WhatsApp is the way a receipt arrives: the crew sends the photo to a number, Obra reads it, replies in their language, and the office reviews the draft. If you read "sends over WhatsApp" and pictured your crew's receipts, that is Obra.
Deciding
If you work alone, quote from your phone, and your market is Chile or another Spanish-speaking country, Obrahub is a purpose-built tool at a low price. If you run a crew in the United States and the thing you cannot see is what each job cost this week, start with Obra, free for one project and $12 a seat after, in whichever language each person on the crew prefers.
