Almost every tracker sets your calorie target from a formula that was built on population averages. For any individual person it can be hundreds of calories wrong, in either direction, and it never finds out. usnapit solves it from your own data instead - over the last eight weeks, so the answer describes the body you have now rather than an average of every version of you.
After two or three weeks of logging, usnapit has your real intake and your real weight trend. From those it works out what your body actually burns - and shows you the whole calculation: days measured, days logged, average intake, weight change. One tap adopts it as your target. Your goal and your macro split still apply on top, and you can go back to the formula whenever you like.
Daily weight swings two or three pounds on water alone, so the chart draws a smoothed line to show the direction - but every number on the screen is a real reading with the date it was taken. What you lost this month is the scale on one morning against the scale on another, and you can go and check both in the Log.
Trends reads by week and by month as well as by day, so one big Saturday shows up as what it is - a single day in a month that is going fine - rather than as the day you broke something. A day inside 10% of its target counts as on budget.
Lose, gain or maintain, and how fast. usnapit turns that into a daily calorie and macro target.
Snap it, scan the barcode, describe it or read a menu. Anything from the last five days is one tap away, so your usual breakfast does not need a photo twice.
Type it, or sync it automatically from Apple Health or Health Connect, and a weight you type goes back the other way.
Trends averages your intake, draws the weight trend, and once there are a few weeks behind it works out a budget you can adopt in a tap.
Most trackers show you a weight line and leave you to decide what it means. usnapit remembers what you actually set out to do, and compares.
Where your goal says you should be today, where you actually are, and the gap between them. The figure is the weigh-in you actually took, and the verdict has a week of your own plan as its tolerance - so a heavy morning is not treated as two weeks of failure.
At the rate you are actually going, when you reach your target weight. It moves as you do, and it is on the first screen you open rather than buried in a chart.
Log lunch on your iPhone and dinner on your Android and you get both. usnapit merges what each device has rather than letting whichever synced last overwrite the other.
A goal set yesterday gets no verdict. One day of a half-kilo-a-week plan is inside what a body moves overnight, so usnapit waits until there is a week behind it before telling you anything about how it is going.
