One range from weight
Daily protein is body weight in kilograms times a factor. Activity and goal select that factor together. Sex, height, and age do not change the math. Age still has to be 18–80 before you can calculate.
Android protein calculator
Find a daily protein target from your body weight
Protein Calculator & Tracker turns your weight, activity, and fitness goal into one grams-per-kilogram range, then lets you log food on the same phone. Entries stay on the device.

- Adults 18–80
A planning range, then a log you control
The calculator does not stack activity on top of a goal. It picks one range. The tracker records only the days you actually log.
Midpoint you can move
The suggested target is the midpoint of the low and high grams. A slider stays inside the displayed range. You can save that amount as the daily goal or share the result yourself.
Food log on the phone
Add an approximate catalog food, a custom food, or a quick gram amount. Repeat a recent meal, edit an entry, or delete it. Empty days are left out of averages.
History without a server
Week and month views, a streak of logged days, and saved calculator sessions stay in local storage. Export or import a CSV only when you pick a file.
How a target is calculated
1
Enter age and weight
Use kilograms, pounds with feet and inches, or stones with meters. The app stores the measurement in kilograms and centimeters.
2
Choose activity and goal
General health, maintain muscle, build muscle, fat loss, or endurance. A custom grams-per-kilogram value is a manual override, not an automatic recommendation.
3
Read the range
You get a low, a high, and a midpoint. Optional meal splits divide the selected target into 3, 4, or 5 meals.
4
Log against that goal
Save the daily goal, then track foods. History counts a streak only on dates that have a log, ending today or yesterday.

How do I calculate daily protein from body weight?
Convert weight to kilograms, then multiply by one grams-per-kilogram range. This app picks that range from activity and goal together. The midpoint is the suggested target.
How much protein per kg should I use?
It depends on the goal. General health can be 0.8–1.2 g/kg. Build muscle is 1.4–2.0 g/kg in this app. These are planning bands, not a prescription.
Can I track protein without an account?
Yes. The app has no account and does not request Internet access. Logs, goals, and calculator sessions stay on the phone.
Does sex, height, or age change the protein number?
No. They can be stored with your profile, and age must be a whole number from 18 to 80, but they do not change the multiplication.
Is there an Android app that logs protein and calculates a target?
Protein Calculator & Tracker does both on Android: a weight-based range, then a food log, history, and CSV export you start yourself.
