Seim – Build Habits

SEIM helps you build habits with small actions, done enough every day — no account needed, no ads, no fees.

JUST DO ONE SMALL THING EACH DAY
Pick one habit for today: drink enough water, walk for 20 minutes, go to bed before 11 p.m., read 10 pages of a book. Each habit is broken into small tasks, and you tick off each one. There are no end-of-week deadlines and no pressure-filled scoring — only "done" and "skipped."

45 HABITS, EACH WITH ITS OWN ROADMAP
SEIM's library has 45 habits across 7 areas: sleep, nutrition, exercise, mindfulness, finance, relationships and discipline. Each habit has a day-by-day roadmap — you can clearly see where you are today, what to do tomorrow, and the days you have missed.

45 READY-MADE CHALLENGE SETS
Don't know where to start? Choose one of 45 challenge sets, from 7 days to 30 days. Tap once and it runs.

CHALLENGE SUGGESTIONS BASED ON YOUR PROFILE
When you set up your profile, you choose your goal: stay healthy every day, lose weight, sleep better or exercise regularly. SEIM uses that goal, along with your BMI, to rank the 3 most suitable challenges at the top — each suggestion clearly explains why. Change your goal and the suggestions change right away.

RUN MANY CHALLENGES AT ONCE
You can run multiple challenges in parallel. A challenge strip at the top of the screen lets you switch between them; below it, only the challenge you have selected is shown, with nothing mixed up.

STREAKS AND STATISTICS
Mark each day you complete, view your ongoing streak, a chart of the last 30 days, weekly statistics and your completion rate. Seeing clearly how far you have come is the most lasting motivation to keep going.

DAILY REMINDERS
Set a separate reminder time for each challenge. Notifications run on your device, even after it restarts.

A DAILY SELFIE
Take one photo each day and view a timeline comparing your photos week by week. Your photos are not posted anywhere — they stay on your device.

AI COACH
Chat in Vietnamese with an AI coach. Ask about sleep, nutrition, exercise, or a habit you keep putting off — the coach uses your profile and current progress to give specific, easy-to-follow suggestions. There is a limit of 30 chats per day. The coach does not diagnose illness and will advise you to see a doctor when needed. You decide whether to share health information with the AI, and you can turn it off at any time in Settings.

CREATE YOUR OWN CHALLENGE
Can't find a challenge that fits? Write your own, or ask the AI to suggest a challenge set based on your idea.

LIGHT AND DARK INTERFACE
Choose light mode, dark mode, or follow your system. Supports Vietnamese and English.

WORKS OFFLINE
The entire habit library, tasks, progress and statistics work offline. Only when you open the AI coach feature does the app send your question over the network.

YOUR DATA STAYS ON YOUR DEVICE
No sign-up needed, no email needed. All your data lives on your own device and is not uploaded to a server. No ads, no analytics tools, no selling data. Delete your data at any time right in the app.
