• After the quick calculation the buttons are clearer: equipment, quote and PDF in one tap. • The installer application is pre-filled with your profile details: you only complete what is missing. • Stability tweaks.

• All of Spanish-speaking Latin America: Costa Rica, Panama, Guatemala, Honduras, El Salvador, Nicaragua, Dominican Republic, Puerto Rico, Venezuela and Bolivia, with their cities, design temperatures, currency and sales tax. • The starting city now comes from the phone's time zone, not its language. • City search: type the name and pick it. • If you mistype the ceiling height (for example 270 instead of 2.7), the app warns you before calculating.

• Uruguay: Montevideo and Salto, with their own design temperatures and solar radiation. Until now you had to calculate using a city from another country. • Equipment prices and quotes in Uruguayan pesos.

Room names are now filled in automatically: "Bedroom 1", "Living room 2". No need to type one before saving. Installers: the sign-up screen now explains what the directory is for. Whoever calculates capacity in your city sees your contact details, with no middleman and no commission. Fixed the units in the quick estimate and the home screen labels, which were showing in another language.

New: quick estimate. Four questions — city, floor area, room type and how much sun — and the capacity right away. From there you can refine the data in the full calculation. Ecuador and Paraguay: Guayaquil, Quito, Manta, Asunción and Ciudad del Este, with official design temperatures. The city is now suggested from your phone's country, and facade orientation is calculated with that city's climate: in the southern hemisphere the sun comes from the north. Equipment prices are shown at local level.

Quote: the tax rate is now suggested based on the selected country instead of a fixed 21%. Lines with no amount no longer appear in the PDF. Argentina: seven new cities — Santiago del Estero, Catamarca, San Juan, Resistencia, Santa Fe, San Luis and Trelew — and design temperatures updated from official National Weather Service data. The app now takes up considerably less space.

Quote fix: line amounts and the total are now shown in the currency of the selected country. Previously, in some countries the line items and the total did not match. Internal performance improvements.

Revised prices. Equipment and quote prices for Latin America now match each country's real market — they used to come out far too high. The catalogue and prices are also chosen by the city of the calculation rather than by the phone's language. Frigorias. In Spain and Argentina capacity is now shown in frigorias per hour alongside kW, both in the app and in the PDF report. Six new cities in Argentina: Rosario, Mar del Plata, Salta, Tucumán, Neuquén and Bariloche. Fixes: summer and winter design temperatures had the same label and could not be told apart; in the load breakdown, the ventilation load was labelled as air flow.

Important fix: going back to change the city or a room's data and calculating again showed the previous result. Every calculation is now redone with the current data.

You can now calculate without creating an account: the calculation, the equipment catalogue and the quote are available right away. An account is only needed to join the installer directory and to leave reviews. Fixed buttons that sat under the Android navigation bar.

Capacity is now shown in BTU/h alongside kW, both in the app and in the PDF report. The installer badge now reads "Documents received". Interface and wording improvements.

Fixed the Back button on Android and in the installers section. Prices adjusted to the local Latin American market. UI and text improvements.

New Latin American markets (Chile, Colombia, Peru) with local cities and equipment catalog. Prices shown in each country's local currency. Portuguese (Brazil) now persists after restart. Cleaner PDF report (EN 12831 · EN 16798 · ASHRAE standards). UI and stability fixes.

• The equipment catalogue now depends on the installation scheme: individual splits, multi-split or ducted. • Equipment is ordered by seasonal efficiency (SEER + SCOP), never by brand. • Fixed model references for LG, Samsung, Gree, Fujitsu and Toshiba. • Installers can add their company name and several phone numbers, each with the languages spoken on it. • Fixed scrolling on large screens and password recovery.
