vSysteme

vSysteme is the secretary that won’t let it slide: an organizer that doesn’t wait for you to remember it. An ordinary to-do list stays quiet. This one reminds you — before the deadline, right on time and after it, until the task is done. Unfinished tasks don’t vanish at the end of the day: they move to today with a mark, so you can see what’s been put off for two weeks in a row. WHAT IT DOES • Tasks for today and any day ahead, with or without a deadline. • Recurring tasks: water the plants on Tuesdays, send the meter readings on the 23rd. Set the rule once, and the task shows up on its own after that. • Supplies: vitamins, medicine, cat food. The app counts what’s left and warns you ahead of time that a pack is running out. • Shared tasks: connect with someone close to you and set tasks for each other. You can see who set a task and who closed it. • Chat with the people you’re connected with — no more digging through messengers for what you agreed on yesterday. • Notifications on your phone and, if you like, in Telegram — including voice input: say “move the gym to tomorrow”, and the task moves. Voice input and the Telegram bot understand phrases in Russian best for now; English phrase support is on its way. WHO IT’S FOR For families who share chores between two, and for anyone tired of keeping meter readings, vitamins and doctor’s appointments in their head. YOUR DATA, HONESTLY We don’t sell data and don’t show ads. What we store and why is written in plain language: https://vsysteme.app/en/privacy/ You can delete your account right in the app, along with everything in it.
