Track an intermittent fast with a live progress ring that fills through the stages your body goes through: fed, fat burning and ketosis. Pick a protocol like 16:8, 18:6, 20:4 or OMAD, start fasting with one tap and see the elapsed time, the time left and when your eating window opens. Edit the start time, keep a reminder for the end of the fast, follow your streak on a calendar and read a history with the average fast, your current streak and every past fast's length. Share a plain-text summary; everything stays on your phone.
Work out a daily calorie target and a macro plan from your body profile and goal, without any sign-up. Set sex, age, height, weight, activity and a goal, then see protein, carbs and fat grams on the macro ring, split the day between breakfast, lunch, dinner and a snack, and watch a weekly projection of how your weight would change. Save plans to compare, log a weekly check-in, and share or save the plan as a text file. General guidance, not medical advice.
Look up the calories of common foods and see how they change with your portion. Search a built-in list of everyday foods, filter by group, drag the portion slider and read the calories and macros for exactly the amount you ate. Save the foods you check often, keep a list of recent lookups and compare two foods side by side with bars that show which one is heavier. Share a plain summary of any portion. Everything stays on your phone and works offline.
Start a 30-day fitness habit and keep the streak alive. Pick plank, squats, push-ups or a daily step goal, then tick each day on a 30-cell calendar where the target grows a little every day. A dark hero card shows today's target and the length of your current streak, a day sheet lets you mark or undo any past day, and restarting or switching challenges keeps every finished run in history with its best streak. Set a daily phone reminder, share a plain-text progress summary, and everything stays on your phone.
Follow the 20-20-20 rule while you work at a screen. Start a session and the app reminds you every 20 minutes to look away for 20 seconds, with a countdown ring and a short eye exercise. Set the interval, break length and work hours, switch the chime on or off, and watch the breaks-taken counter and a 7-day chart grow. Everything stays on your phone.
Quit smoking one day at a time. Set the day you stopped and see your smoke-free days, the cigarettes you avoided and the money you saved update as you go. A recovery timeline walks you through what your body does from 20 minutes to a year, a one-tap craving log helps you spot your triggers with a fresh tip each time, and you can note slips honestly and read your own reasons to keep going. Share a plain summary of your progress whenever you want. Everything stays on your phone.
Track your period in a moment: tap Log today to mark the first or last day, add symptoms on any date and see a cycle ring that shows which day of your cycle you are on. The app works out your average cycle from the periods you logged and shades the expected range of days on a month calendar and in history, so the next period is a window and not one guessed date. Set a reminder before the expected day, export your log as a CSV file, and keep it private with an optional PIN. Predictions are estimates only and nothing leaves your phone.
Log your blood sugar with the moment it was taken: fasting, before a meal or after a meal. See each reading inside or outside your target range, follow a trend chart with the range band drawn in, and check your average and time in range at a glance. Switch between mmol/L and mg/dL and every value converts, set your own targets, add a short note and export the whole log to a CSV file to share with your doctor. Everything stays on your phone.
Keep a simple diary of every blood-pressure reading: enter systolic, diastolic and pulse and the app sorts it into normal, elevated, high and crisis zones as you type. A colour-band chart shows the trend, while morning, evening and 7-day averages and a category count tell you where you stand. Repeat the last reading in one tap, edit or delete any entry with Undo, set a daily reminder, share a summary or export everything as a CSV file. All of it stays on your phone.
Keep a calm diary of what you eat: log each meal with its time, a note, an optional photo and feeling tags, then look back over today's timeline, a month of days and a weekly pattern that shows which feelings follow your meals. Repeat yesterday in one tap, search your notes, and export everything as a CSV. All of it stays on your phone.
Log what you eat through the day and watch a calorie ring fill up against your daily target. Pick meals (breakfast, lunch, dinner, snacks), choose from a built-in list of about 80 common Vietnamese and general foods with serving sizes, or create your own foods that are saved for next time. Track protein, carbs and fat, keep favourites and recent foods a tap away, and open the history to see your weekly average. Share the day summary as text. Everything stays on your phone and all nutrition values are estimates.
Keep a simple ride log for every bike you own: log distance, time and elevation and the app works out your average speed, weekly and monthly totals and a speed trend over time. Track each bike's odometer and set a service interval so a reminder appears before it is due, repeat your last ride in one tap, add notes to a ride, share a ride summary or export the whole log as a CSV file. Everything stays on your phone.
Keep a simple diary of every run: enter the distance and the time and the pace and speed appear as you type. Weekly distance bars and a clean list show your week at a glance, while Stats adds monthly totals, personal bests for 1K, 5K and 10K, and how many kilometres each pair of shoes has covered. Repeat the last run in one tap, edit or delete a run with Undo, and share a summary or export everything as a CSV file. All of it stays on your phone.
Schedule your medicines with the times and days they repeat, then tick each dose off as you take it. See a today timeline, your adherence over the last week, how many days your stock still lasts and a warning when it runs low. Doses arrive as phone notifications, and you can share a weekly report. Everything stays on your phone.
Sit down and let a calm circle guide your breath: choose 10 minutes or any length, add a preparation countdown and interval bells, and hear a soft synthesised singing bowl open and close every session. The breathing circle swells and settles with a steady pace while the countdown runs, so you can follow it with your eyes closed. Every finished session is kept in a history with your current streak, best streak, total minutes and how many days this week, and a tap on a past session deletes it with undo. Presets, a custom stepper and your bell tone make it ready in one tap. Everything stays on your phone.
Run HIIT, boxing or any work-and-rest workout: set warm-up, work, rest, rounds and cool-down, then follow a big full-screen timer that changes colour for every phase and beeps for the last three seconds. Built-in presets (Tabata, Boxing, HIIT, EMOM) start a whole plan in one tap, your last setup and your own presets come back next time, and a weekly recap counts the sessions you finish. Everything stays on your phone.
Find the calories your body burns at rest and turn them into a real daily plan. Enter your sex, age, height and weight, drag the drawn sliders and pick an activity level to get your BMR and maintenance calories with the Mifflin-St Jeor or Harris-Benedict formula. The flame meter shows the lose, keep and gain bands, each goal gets its own daily target and a suggested protein, carb and fat split. Save profiles for later, share a plain-text plan and everything stays on your phone.
