Rainbet

Rainbet is a private, offline notebook for tracking the temperature and humidity of the different zones in and around your home - room by room, season by season. Every home has its own microclimate Rainbet. The bedroom, the basement, the greenhouse, the pantry, and the balcony rarely behave the same way. This app helps you record what is actually happening in each of these spaces over time, so you can compare them and understand how they change Rainbet. Create zones for the rooms and areas you want to track - bedroom, kitchen, balcony, basement, wardrobe, attic, greenhouse, storage room, garage, bathroom, pantry, plant shelf, or any custom zone you name yourself. For each zone, manually log the temperature, humidity, date, time, and optional observations whenever you take a reading. Over weeks and months, this builds a real history for every space in your home. Rainbet is especially useful for old houses, country houses, basements, cellars, greenhouses, storage rooms, plant collections, garages, and apartments with condensation or humidity concerns - anywhere the conditions vary noticeably from room to room. You are always in control of your data. You can export it at any time, and you can delete your measurement history or reset the app completely from Settings.
Rainbet is a manual record-keeping tool. It does not measure anything automatically, and it does not connect to sensors, smart-home systems, or weather services. It does not detect environmental hazards, diagnose building problems, assess indoor air safety, or replace professional inspection equipment. All values are entered by you, and all observations are simply what you choose to record.
Rainbet becomes more useful the longer you use it - the more readings you log, the clearer the picture of how your home actually behaves across the day and across the seasons.
