All the apps and services CodeSand builds and runs, in one place.
Prepare for many kinds of exams in one app — from college entrance and civil service to certifications and language tests. Just enter your start date to see your progress against exam day, study with word lists, quizzes and practice tests, and talk with others preparing for the same exam. You'll also get reminders for exam and results dates.
A short guided setup gets your first D-day added right away. Keep your countdowns in view with a variety of home screen widgets and styles, and share the same event with the people who are counting down with you. If you'd rather keep things private, you can store your data on your device only.
Open HWP and HWPX documents you receive right on your phone, no PC needed. Even password-protected files open, and you can convert them to PDF or print straight from your phone.
Measure the noise around you in decibels and calibrate it for your device. Your measurements are saved so you can review them in hourly graphs and more, and export a PDF for your records. It isn't legal evidence, but reference lines such as noise regulations for apartments and WHO guidelines help you judge whether the noise is really excessive.
