7day.

Your weight changes every single day — after a salty meal, a hard workout, a bad night's sleep. None of those daily swings tell you what's actually happening.

Your weekly average does.

7day is a bodyweight tracker built around one idea: the 7-day rolling average is your true weight. Log once a day, and let the weekly average show you what's real.

HOW IT WORKS

Open the app. Type your weight. Done. The whole thing takes about 3 seconds.

Behind that simple log, 7day calculates your weekly average automatically. That's the number you check. That's the number that tells you whether your cut is working, your bulk is on track, or your maintenance is dialed in.

PLAN YOUR TRAINING BLOCKS

Set a goal: lose 0.5% per week for 12 weeks. Or gain. Or maintain. 7day maps out your target week by week and shows you exactly how your actual weekly average compares to the plan. No guessing, no vibes — just clean data against a clear goal.

SEE YOUR REAL PROGRESS

The progress chart plots weekly averages over time with your goal line overlaid. You'll see your actual trend — not the random noise of daily fluctuations. Week-by-week breakdowns show your average, entry count, range, and how you're tracking against your block.

IMPORT YOUR HISTORY

BUILT FOR PEOPLE WHO KNOW WHAT THEY'RE DOING

7day is not a calorie counter. It doesn't have motivational quotes, streak badges, or social features. It's a precision tool for people who program their training in blocks, track their macros, and want clean weekly data without the clutter.
