Mobile App Development in Stockholm, Sweden

Sustainability / Food Tech

A Stockholm-based environmental startup wanted to build a mobile app connecting consumers with restaurants, cafes, bakeries, and grocery stores that had surplus food at the end of the day — reducing food waste while providing consumers with affordable meals. Sweden wastes 1.3 million tonnes of food annually (€4.5B value), and Stockholm's sustainability-conscious consumers were eager for solutions. The startup had proven the concept with a small manual operation (20 partner restaurants in Södermalm, coordinated via Instagram DMs), but needed a mobile platform to scale across Stockholm and then to Gothenburg, Malmö, and other Nordic cities. The challenge: building a two-sided marketplace where restaurants could list surplus food with minimal effort and consumers could discover, purchase, and pick up meals seamlessly — all while handling the timing sensitivity (food must be picked up within specific windows) and the unpredictable nature of surplus (restaurants do not know exactly what will be left over until late afternoon).

We built the food rescue platform (consumer app + restaurant partner app) over 12 weeks: (1) Consumer app: map-based discovery showing nearby restaurants with surplus food. Each listing: restaurant name and photo, food type ("Surprise bag — mixed Asian dishes, serves 1-2"), original price, rescue price (typically 60-70% discount), available quantity, and pickup window (e.g., 18:00-19:30). Listings are time-sensitive and disappear when the pickup window closes. Swish payment for instant checkout (one-tap purchase via Swish — no card entry, no friction). Push notification: "New rescue available at your favourite bakery in Östermalm — 3 remaining." (2) Restaurant partner app: restaurants list surplus food in under 60 seconds — select food type (from pre-set categories), quantity, and pickup window. The app learns the restaurant's patterns and pre-fills likely listings ("You usually have 5-8 bakery items leftover on Wednesdays — shall we create a listing?"). Dashboard showing items rescued, CO2 saved, and earnings. The partner app minimises restaurant effort — the entire point is that surplus management should not feel like additional work. (3) Pickup flow: consumer purchases via the app, receives a QR code, goes to the restaurant during the pickup window, and the restaurant scans the QR code to confirm pickup. No cash handling. No awkward negotiation. Clean, digital, Scandinavian-efficient. (4) Gamification (honest): CO2 impact tracker — each purchase shows the CO2 equivalent saved ("you saved 2.1 kg CO2 — equivalent to driving 8 km"). Monthly sustainability summary. Community leaderboard (optional — Swedish users are motivated by collective impact, not individual competition). Tree planting partnership: every 100 rescues plants a tree. (5) BankID: for restaurant partner onboarding (identity verification of business owners), ensuring only legitimate food businesses list on the platform. Organisationsnummer (Swedish business registration number) verified during onboarding. (6) Swish Commerce: all consumer payments via Swish (one-tap). Restaurant payouts via Swish or bank transfer (daily settlement). Platform commission: 15% of rescue price. (7) IMY compliance: location data (for nearby restaurant discovery) with clear consent, food purchase data processed with purpose limitation, and transparent privacy notice. Swedish food safety regulations (Livsmedelsverket) followed for the platform's food handling guidance.

App adoption: 95,000 consumer downloads within 6 months (Stockholm population: 1 million). Partner restaurants: 420 restaurants, cafes, bakeries, and grocery stores in Stockholm. Monthly rescues: 65,000 food bags rescued per month by month 6. Food waste prevented: 280 tonnes in the first year. CO2 equivalent: 750 tonnes CO2 saved (displayed to users — the environmental impact messaging was the primary adoption driver). Consumer engagement: 4.2 average orders per active user per month. Average rescue price: SEK 45 (original food value approximately SEK 130). Consumer satisfaction: 4.8-star App Store rating — the highest-rated food app in Sweden. Restaurant satisfaction: partner NPS +72 — restaurants appreciated the zero-effort surplus management and the sustainability branding. Revenue: monthly GMV SEK 2.9M × 15% commission = SEK 435K monthly platform revenue by month 6. Swish payment: 98% of transactions via Swish (2% Apple Pay from tourists). Nordic expansion: launched in Gothenburg (month 7) and Malmö (month 9) using the same app with city-specific configuration. Norwegian (Oslo) and Danish (Copenhagen) launches planned using the Nordic expansion architecture. Funding: raised SEK 45M Series A based on Stockholm traction and Nordic scalability. Implementation cost: SEK 1.6M (approximately €140,000). Annual revenue run-rate: SEK 5.2M (growing 12% month-over-month).
