Melbet

Melbet is an offline tool that helps cyclists recognize clouds and decide whether to take a waterproof. The app shows all ten genera from the WMO International Cloud Atlas and their fifteen species, with base and top heights, typical weather effects, and common look‑alikes. It lets you tap the sky band where a cloud appears – high, middle, low, or spanning all levels – and then use simple visual cues. You can estimate size with your hand: one finger covers about 1°, three fingers about 5°, which distinguishes cirrocumulus, altocumulus and stratocumulus. Texture descriptions such as threads, grains, veil, heaps, rolls, or sheet further aid identification. For each identified cloud the app displays its real altitude on a scale from ground to 13 km and a brief note on what weather to expect in the next hours. This helps you quickly decide to pack a waterproof or ride without it. You can save each morning’s cloud observation, mark whether it rained, and view a strip of the last fourteen days. The summary shows how often the sky’s advice matched your commute, giving a clear picture of your riding conditions over time. All content is included in the app and works completely offline. With Melbet, your favorites, notes, progress, and personal data are stored only on your device, with no registration, accounts, or cloud synchronization required.
