Fitlog - Fitness Log
Fitlog is a plain, quick workout diary. Each entry records what you did (running, walking, cycling, swimming, yoga, weight training, dance, tennis, basketball, soccer or other), how many minutes it took, the calories you estimate you burned, and the date. The dashboard then shows how this week is going against a goal you set yourself.
It suits people who want a record of their activity without a full training platform: someone getting back into exercise, a person who mixes several sports in a week, or anyone who simply wants to see whether they really moved as often as they planned. There are no plans to follow and no social feed, just your own numbers.
The web version runs in your browser with no account or sign-up. Your workouts and goal are saved in this browser on this device.
The app runs entirely in your browser. What you enter is saved only on this device.
How to use Fitlog
- Open the Record tab. Tap Record in the bottom bar, or Add New Record on the dashboard. The New Workout Record form appears.
- Choose the workout type. Pick one of the eleven types from the Workout Type list. Choose Other for anything that is not listed, such as hiking or rowing.
- Enter minutes and calories. Type the duration in minutes and the calories in kcal as whole numbers. Both fields are required. Use your watch, a machine display or a rough estimate for calories.
- Check the date and save. The record date defaults to today. Tap the calendar icon to log a session from an earlier day, then tap Save.
- Set a weekly goal. In the Goals tab, enter how many workouts, how many kcal and how many minutes you aim for each week, then tap Set Goal. You can update it later.
- Watch your progress. Home shows Weekly Progress bars for sessions, calories and minutes against your goal, plus your five most recent workouts.
- Review your statistics. Open Statistics and switch between Weekly, Monthly and Yearly to see line charts of calories and duration and a breakdown by workout type.

Making a workout log useful
Log what you can measure honestly
The most reliable numbers in any exercise diary are the type of activity and how long you did it. Minutes are easy to time and hard to fool yourself about, so they are a good backbone for a log. Calories are different: the figure on a treadmill, a watch or a website is an estimate built from assumptions about your weight, age and heart rate, and two devices can disagree a lot for the same session.
That doesn't make calorie numbers useless. Used consistently, they let you compare one week with another. The trick is to use the same source each time and to treat the total as a trend, not as an exact count.
Setting a weekly goal you will actually hit
Weekly goals work better than daily ones for most people because life is uneven: a busy Tuesday can be made up on Saturday. Start from what you did over the last couple of weeks, not from what you wish you did. If you managed two sessions a week, a goal of three is a stretch; a goal of six is a recipe for feeling behind by Wednesday.
Many public health bodies suggest that adults aim for around 150 minutes of moderate activity, or about 75 minutes of vigorous activity, spread across the week, plus muscle-strengthening work on two days. A minutes goal is a natural way to track that kind of target. If you are new to exercise or have a health condition, build up gradually and talk to a professional first.
Reading the charts
A single week tells you very little; a month or a year shows patterns. Look for gaps (holidays, illness, busy periods at work) and for slow drift, such as sessions getting shorter. The type distribution is useful for balance: if almost everything is running, you might add some strength or mobility work, and if everything is low intensity, a harder session now and then may help fitness.
When progress stalls, change one thing at a time, such as adding ten minutes to one weekly session, and let the log show whether it stuck.
Consistency beats intensity
The habit of recording is itself a motivator. Logging straight after a session takes a few seconds and keeps the record complete. Missing a few entries is normal; just add them later with the date picker rather than abandoning the log.
Frequently asked questions
Where is my data stored?
Only in this browser on this device. There is no account and nothing is uploaded. Clearing site data, using a private window or switching browsers or devices means your workouts won't be there.
Can I edit or delete a workout?
Not in the current version. Check the type, minutes and calories before you tap Save.
How does Fitlog calculate calories?
It doesn't. You type the number yourself, for example from a fitness watch, a gym machine or an online estimate, and Fitlog adds the numbers up.
When does the week start?
Weekly progress and the Weekly statistics view count from Monday of the current week.
What is different from the phone app?
The iPhone and Android apps store data on the phone and show ads that can be removed with a subscription. The web version has no ads or purchases, and your records stay in the browser instead of the phone.
Can I use it in another language?
Yes. It follows your browser language, and you can also add ?lang=ja, ?lang=de and so on to the page address.
Limitations of the web version
- Workouts can't be edited or deleted after saving
- Calories are entered manually; nothing is measured or synced from a watch
- Data stays in one browser and does not sync between devices
- No export or backup in the web version
