SecureChats Keyboard es un teclado personalizado para iOS que integra cifrado extremo a extremo (E2EE) directamente desde tu teclado. Cifra y descifra mensajes en cualquier aplicacion de mensajeria sin depender de servidores externos, sin cuentas y sin recopilar ningun dato. SecureChats Keyboard is a custom iOS keyboard with built-in end-to-end encryption (E2EE). Encrypt and decrypt messages in any messaging app with no servers, no accounts, and zero data collection. -- COMO FUNCIONA / HOW IT WORKS -- El teclado utiliza el Signal Protocol con intercambio de claves post-quantum Kyber (ML-KEM) mediante PQXDH. Los usuarios intercambian invitaciones criptograficas copiando y pegando texto codificado. Una vez establecida la sesion, cada mensaje se cifra localmente en tu dispositivo y solo puede ser descifrado por el destinatario. Ningun intermediario, servidor o tercero puede leer tus mensajes.

Once a session is established, every message is encrypted locally on your device and can only be decrypted by the intended recipient. No intermediary, server, or third party can read your messages. -- SEGURIDAD / SECURITY -- - Signal Protocol: Double Ratchet, forward secrecy y seguridad post-compromiso. - Post-Quantum: Kyber/ML-KEM protege contra ataques de computacion cuantica futura. - Almacenamiento cifrado: todos los datos locales se cifran con AES-256-GCM. La clave maestra se almacena en el iOS Keychain respaldado por Secure Enclave. - Sin red: la aplicacion no realiza ninguna conexion de red. Funciona completamente offline. - Signal Protocol: Double Ratchet, forward secrecy and post-compromise security. - Post-Quantum: Kyber/ML-KEM protects against future quantum computing attacks. - Encrypted storage: all local data is encrypted with AES-256-GCM.

PoolDoseLog logs your pool and hot tub water tests and works out how much of each chemical to add. Enter the free chlorine, combined chlorine, pH, total alkalinity, calcium hardness, stabiliser and water temperature from your test kit or strips, and every dose you need appears on one screen. The maths is shown too. Water volume, the gap to your target, the strength of your product and the rounding are all laid out, so you never have to take a number on trust. Target ranges come as Standard, TFP style or Manufacturer, and every single value can be changed. Chlorine, bromine and salt water (SWG) pools are all supported, and outdoor pools have the effect of stabiliser folded into the calculation. Hot tubs are supported as well. Enter your water volume directly, or work it out from rectangle, round, oval or freeform dimensions. Your own products go in too, down to the strength of your liquid chlorine and which acid you use. Everything you add is kept in a dosing log, and your readings are plotted on a chart. Reminders can be set for water tests, filter cleaning, backwashing and salt cell cleaning. Records are stored on your device and backed up automatically once a week. You can also send a copy off the device as a zip file and restore from it. Tests and doses export to CSV, and tests can be imported from CSV. There is no cap on how many tests you can log. Units switch between gallons, ounces and Fahrenheit or litres, grams and Celsius.
