Mivo answers the oldest question in gardening and farming: how much water does my crop actually need, and when? It is built entirely on FAO-56, the United Nations reference method used by agronomists worldwide. Enter a day's weather — temperatures, humidity, wind and sunshine — and Verdant evapotranspiration computes reference evapotranspiration with the full Penman-Monteith equation: extraterrestrial radiation from your latitude, clear-sky radiation, net longwave losses, vapour pressure deficit, every step shown with its equation number. Then it goes further. Pick a crop and a soil, and Verdant evapotranspiration builds the crop coefficient curve across four growth stages, steps a daily root-zone water balance, and tells you the day your plants will start to stress — before they show it. Each irrigation is scheduled at a trigger depth you control, converted to litres and runtime at your actual flow rate, so the number on the screen is the number at the tap. Everything is transparent. The Reference tab shows the radiation chain from the top of the atmosphere down to the crop. A built-in method page lists every FAO-56 equation the app uses. Five stations on four continents ship preloaded with monthly climate normals, and a temperature-only Hargreaves cross-check is always one tap away. Plan across fields: three sample gardens from California turf to Arizona maize come ready to explore, and you can add your own with custom area, flow and efficiency. Log what you actually watered, export a one-page season report as PDF, and watch the balance close to four decimal places. No accounts. No network. No tracking. Your fields stay on your device in a single JSON file you can export and keep. ## Key features - FAO-56 evapotranspiration calculation - Crop coefficient curve generation - Daily root-zone water balance - Customizable irrigation triggers - Exportable season reports (PDF) - Offline functionality - No user accounts or tracking ## Is Mivo safe?

Mivo utilizes the FAO-56 method, specifically the Penman-Monteith equation, to calculate reference evapotranspiration. It then incorporates crop coefficients and soil data to determine daily water balance and predict when plants may experience stress. ### What kind of weather data does Mivo use? Mivo uses daily weather inputs such as temperatures, humidity, wind speed, and sunshine. It can also access preloaded monthly climate normals from stations on four continents. ### Can Mivo be used for different crops and soils? Yes, Mivo allows you to select a crop and soil type to build a specific crop coefficient curve and root-zone water balance. It also comes with sample gardens and the ability to add your own custom fields. ### How does Mivo help with irrigation scheduling? Mivo schedules irrigation based on a trigger depth you control, converting the required water into liters and runtime based on your actual flow rate. This ensures the number displayed is accurate for your tap. ### Does Mivo require an internet connection to work? No, Mivo is designed to work offline. It does not require an internet connection, accounts, or tracking, keeping your field data solely on your device. ### Can I export my data from Mivo? Yes, you can export a one-page season report as a PDF. Your field data is stored locally in a single JSON file that you can also export and keep. ### What is the update frequency for Mivo? The latest version, 1.1.0, was last updated on October 30, 2026. While specific update frequency isn't detailed, the app has seen recent updates. ### Is Mivo suitable for beginners in farming? Mivo is built on a professional FAO-56 methodology, but its transparent approach and sample gardens make it accessible for those learning about precise crop water management. ## Version history (last 2 releases) ### 1.1.0 — 2026-10-30 Refined Mivo Evapotranspiration with clearer FAO-56 calculation breakdowns, improved crop growth-stage and root-zone water balance tracking. ### 1.0 — 2026-10-22 No release notes. ## Related topics [mivo](https://appshunter.io/ios/topics/mivo) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
