Goal Streak: 40 Day Challenge

Take the 40 day challenge against one bad habit. Goal Streak is a simple habit tracker that asks you one honest yes-or-no question every night. Say YES and your streak grows. Say NO and it starts again, but your calendar keeps every clean day you earned.

No to-do lists, no complicated setup. Pick the habit you want to quit or build, write your question, and check in once a day. Forty days is long enough to change something and short enough to finish.

HOW IT WORKS
• Create a goal card: a name, a daily question ("Did I skip sugar today?") and a target. 40 days by default, or set your own.
• Get a reminder at the time you choose (10 PM by default).
• Answer YES or NO and slide to confirm. Answers are locked, so your streak stays honest. No editing yesterday.
• Missed a night? Answer the missed days later, oldest first.
• Reach your target and the goal moves to Achieved, with your whole journey saved.

QUIT BAD HABITS
• Smoking or vaping
• Sugar, junk food or late-night snacking
• Social media, doomscrolling or gaming
• Alcohol, caffeine or energy drinks
• Nail biting, sleeping late, skipping workouts

OR BUILD GOOD ONES
• Read 20 pages a day
• Go to the gym or take a daily walk
• Stick to your diet
• Study, journal, meditate or pray on time

WHY ONE QUESTION A DAY
Most habit tracker apps ask you to tick ten boxes a day, and people give up on the app before they give up the habit. Goal Streak keeps it to one question per goal, so a check-in takes five seconds and you keep going for all 40 days.
