Source is the app for commercial greenhouse growers. Starting with the fastest, most reliable way to measure your crop. Scan a QR tag on a truss, log what you see, and move on. Built for tomato growers and expanding into other crops soon. Source is built around our Crop Assessment System: you log one observation at a time while walking the greenhouse, and Source assembles them into a complete picture of your crop. The app tells you exactly what to measure each round, so measurement is fast, consistent, and complete. CROP ASSESSMENT SYSTEM QR scanning: scan a tag on a truss or stem to identify the plant instantly. Scan any tag on a stem and the app knows which trusses belong together — no stem numbers to look up. Task-guided rounds: Source directs you to the right paths, poles, and stems, and tells you what's due: register a new stem, add a truss, count flowers and set fruits, or monitor ripening. Fast logging: user-friendly steppers, large touch targets, and a scanner built for bright, real greenhouse conditions. Truss lifecycle tracking: register a new truss, count flowers and fruit set, mark trusses fully set, add ripening photos, and mark harvested or pruned at end of life. Coverage tracking: see progress across every path, pole, and stem so you know exactly what's left and nothing gets missed. Offline-first: works with no signal in the greenhouse and syncs automatically when you're back online. WHY SOURCE Faster measurement rounds: small, targeted observations replace slow full-stem snapshots, so you cover more plants in less time. Better data quality: attributing every truss to the right stem produces accurate fruit-set rates and crop metrics. Nothing missed: coverage tracking makes skipped and hard-to-find trusses obvious. Smarter forecasting: your measurement data feeds Source.ag's AI models for harvest forecasting and yield insights — better data means more accurate forecasts. One platform, growing with you. Source is expanding into a complete toolkit for greenhouse cultivation, with more grower features on the way. Source works with your Source.ag account. New to Source? Get in touch at source.ag. Source is part of Source.ag's AI platform for commercial greenhouse horticulture — turning what you observe in the greenhouse into smarter cultivation decisions.

Verdict
The clearest difference is update cadence: Source.ag at every 5 days against Priva Notification Center's every 3 months. Priva Notification Center's advantage is device support (3 vs 1) and iOS requirement (14.0 vs 16.4). On price, ads and in-app purchases there is nothing between them.
