Think you’re buying from a cool indie granola brand? Surprise—it’s owned by the same conglomerate that makes engine degreaser and (allegedly) sells your info to the CIA. Buy’r is your pocket-sized truth serum: scan any grocery product and see exactly who profits, from your local co-op to a megacorp with 19 shell companies and a yacht named Tax Haven. While other apps rate your food or hand out “approved” badges, we don’t tell you what’s good or bad. We just show you the facts—who owns it, what’s in it, and how processed it is—so you can decide what fits your life, values, and oddly specific food rules. Because real empowerment doesn’t come from a green checkmark—it comes from knowing the truth. OUR MISSION: We’re a small, self-funded team on a big mission: radical transparency in the grocery aisle. No corporate backing, no brand sponsorships—not even from the “cool” ones. Whether you're avoiding shady corporate practices, trying to support real small businesses, or just tired of decoding labels that sound like marketing Mad Libs, Buy’r puts the power back in your hands—where it belongs. DISCOVER THE TRUTH BEHIND EVERY PRODUCT: Barcode Scanning - Point. Scan. Boom, instant dossier on the product, brand, and parent company. CIA-level info without the espionage. Ownership Discovery - Find out if that "small batch, artisanal vibe" is real or just another product of a corporate rebrand strategy. Brand & Company Spotlights - Deep-dives that feel like true crime documentaries—but for shampoo and salad dressing. SMART SHOPPING TOOLS: Custom Ingredient Filters - Whether you're allergic to gluten or just emotionally allergic to corn syrup, filter it all. Presets, breakdowns, the works. Shopping Lists with Full Integration - Build lists that actually sync with your pantry. No more accidental double-buying basil for the fifth time. Pantry Manager - Take control of your pantry like the food hoarder CEO you were born to be. Recipes and meal planners are in development. Receipt Scan Import - Snap a pic of your Kroger or Walmart receipt—get your pantry logged in faster than a teenager logging into TikTok. NUTRITION & TRANSPARENCY: Detailed Nutrition Breakdown - We don’t just show calories—we show what those calories are hiding. Ultra-processed red flags, ingredient types, and what your food is actually made of (hint: it's not love). Community Ratings & Reviews - Because the hive mind can be smarter than the label. See what real people think—no bots, no BS. EDUCATIONAL & ENGAGING: Interactive Quizzes - Think you know who owns your “indie” oat milk? Let’s test that brand loyalty. Random Spotlight Carousel - A surprise-a-day from family-owned gems you probably missed while being hypnotized by mega-brand marketing. 31 Achievement Badges - Scan. Learn. Flex. Prove you’re not just a consumer—you’re a conscious one. ALL FEATURES: - Instant barcode scanning - Ownership discovery & brand family trees - Deep-dive spotlights on companies (yes, even the shady ones) - Ingredient filters with preset logic packs - Smart, integrated shopping lists - Pantry tracking with actual usefulness - Receipt scanning from major grocers - Transparent nutrition + processing breakdowns - Community-powered reviews - Corporate guessing games (a.k.a. quizzes) - Indie brand discovery carousel - 31 achievement badges for your consumer resume - Randomized daily brand spotlights SUBSCRIPTION OPTIONS: Free Forever Basic scans + product lookups 1 shopping list 20 pantry items Lite spotlight access (just a taste) Premium — $5/month or $50/year Unlimited scans, lists, and pantry tracking Full ingredient filtering Full spotlight content Receipt scanning All quiz + discovery features Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
