Hey Product Hunt. I kept doing the same thing in the grocery store: pick up a product, flip it over, read a wall of ingredients I can't pronounce, and put it back without actually knowing if it's fine. The existing scanners give you a score. Useful, but I always wanted the why. Which ingredient is the problem? Is it a real concern or internet fear-mongering? What should I grab instead? So Osana does three things: 1. Scan a barcode, a label, or just take a photo. No typing. 2. Get a 0 to 100 score with the full breakdown: each additive, its risk tier, the processing level, and what pulled the score down. 3. See cleaner alternatives for the same product, with the sources behind every call. The methodology is public, because a score you can't verify is just an opinion. Two things I obsessed over: it has to work while you're standing in the aisle (a few seconds, max), and the additive database updates within 48 hours of new FDA, EFSA, or IARC decisions. No stale data. I'm a solo founder and this is early. Most useful thing you can do today: scan something in your kitchen and tell me where Osana is wrong or unclear. I'll be in the comments all day.

I build Osana alone: iOS, Android, the website, the scoring engine, everything. The bottleneck was never ideas. It was the distance between knowing exactly what the product should do and actually shipping it. Osana scans a food label and explains what's inside. The hard part is depth: every additive classified by risk, NOVA processing level, sources for every call. That normally takes a team. With Astra I rebuilt the scoring engine myself, from nutrition scoring to additive risk tiers, plus the pipeline that updates our database within 48 hours of new FDA, EFSA, or IARC decisions. Work that used to sit in a backlog for months now ships in days. The real change is ambition. I stopped building another food scanner and went after the version I actually wanted: every claim traceable to a public source, no black box. When one person can build that, the mission stops being a side project. It becomes something people trust with what they eat.
