Do your biggest Goals keep slipping into "someday"? Goal Tracker and Challenges turns that drift into a Goal you can actually run—link Habits, Tasks, and focus sessions, then unlock exclusive Badges when you finish. Goal Tracker and Challenges is an all-in-one personal goal app that breaks what you want into check-ins, next actions, and focused time, then keeps you moving with Points and Rewards. "I set a writing Goal, tied it to my morning Habit and a short Pomodoro, and unlocking the Badge made the finish feel real." — Maya L., designer Download Goal Tracker and Challenges today and start turning Goals into results. WHY CHOOSE "Goal Tracker and Challenges"? 1. SET GOALS AND STAY ON TRACK Turn a vague ambition into a Goal with rules you control—daily streaks, total counts, or a time range you pick. Link the work that supports it, then keep going until the Badge is yours. 2. BUILD HABITS THAT MOVE YOUR GOALS Give every check-in a Point value so progress is visible, not hoped for. Put negative Points on Habits you want to shrink, and add extra bonuses or penalties when you finish early, on time, or late. 3. BREAK BIG GOALS INTO DAILY ACTIONS Use Lists and Tasks to pull the next step out of your head, then sit down with a Pomodoro when you need deep focus. Small actions stack; the Goal stops feeling too big to start. 4. EARN REWARDS YOU ACTUALLY WANT Build a personal Rewards catalog with thresholds you choose, and redeem when the Points are there. Pair that with Behavior rules—Should and Don't—so the day itself can add or subtract, not only the plan. KEY FEATURES 1. GOAL TRACKING Create personal Goals with daily, weekly, or monthly cycles—or a custom time range. Link Habits, Behavior rules, Tasks, and Pomodoro sessions, and unlock exclusive Badges when you complete them. 2. HABIT TRACKER Run repeating Habits and assign Points or Rewards to each check-in. Use negative Points to curb what you want to stop, plus extra bonuses or penalties for early, on-time, or late completion. 3. LISTS & TASKS Break a big Goal into the next action with GTD-style Lists and Tasks. Assign Points or Rewards to each Task so progress stays visible. 4. POMODORO TIMER Focus for 25 minutes and earn Rewards automatically. Set timer Goals such as earning Points for each stretch of focus, and link sessions to Habits. 5. BEHAVIOR GUIDELINES Log Should and Don't rules on the spot—earn Points for what you want more of, and deduct them when a Don't happens. 6. REWARDS Build a personal Rewards catalog with Point thresholds you choose. Redeem when you have enough, and add notes so each Reward stays personal. 7. HOME SCREEN WIDGETS See today's Tasks, Goal progress, and Point changes on your Home Screen—no app launch needed. 8. TEMPLATES Start from 300+ preset Habit, Task, Reward, and Behavior templates when you do not want a blank page. 9. CHARTS See Point trends, Task completion, and Reward history in one place so progress is easy to review. 10. THEMES & DARK MODE Pick a skin that fits your style, including Dark Mode.
