Humidity and temperature change how your nail products behave. Gel wrinkles, acrylic sets too fast, dip powder clumps, polish won't dry — and you blame the product. The real cause is the weather. NailCast checks your local conditions and tells you what to expect before you start. HOW IT WORKS 1. Set your product type: gel polish, acrylic, dip powder, or regular polish. 2. NailCast fetches your local temperature and humidity. 3. You get a Nail Score (0–100), product-specific tips, and adjusted cure or dry times for today. It takes 15 seconds to set up. No account required. TODAY'S NAIL SCORE A simple 0–100 score tells you how favorable conditions are right now. Green means go. Yellow means adjust. Red means wait if you can. PRODUCT-SPECIFIC GUIDANCE Each product reacts differently to humidity and temperature. NailCast gives you targeted tips: — Gel polish: wrinkling risk, suggested cure time adjustment — Acrylic: set speed warning, workspace temperature tip — Dip powder: clumping risk level, activator timing — Regular polish: estimated dry time based on current humidity Upgrade to Pro for deeper insights: — Hourly forecast: see conditions for the next 12 hours — Best time today: find the window with the highest Nail Score — 7-day nail conditions forecast — Multiple product profiles (all 4 types at once) — Condition alert notifications PRIVACY FIRST All settings are stored locally on your device. No account, no tracking, no ads. Location is used only to fetch weather data from a public API (Open-Meteo). Your coordinates are never sent to our servers. This app provides general guidance based on weather conditions. It is not a substitute for manufacturer instructions or professional training.
