Your weight changes every single day β 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 β 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 β 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 Already tracking weight in a spreadsheet? Import your data via CSV and see your full history inside 7day from day one. 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. - Log weight in ~3 seconds - Automatic 7-day rolling averages - Block-based goal planning (cut / bulk / maintain) - Weekly average progress charts with goal overlay - Week-by-week breakdown with color-coded deltas - CSV import and export - Minimal, calm, distraction-free design

SEE YOUR PROGRESS WEEK BY WEEK Your weight naturally changes from day to day. Water, salt, sleep, digestion, and other everyday factors can move the number on the scale even when your overall progress hasn't changed. Trendio smooths those daily fluctuations into weekly averages. Instead of wondering what today's number means, you can simply look at your week and see: This week: 138.6 lb Last week: 139.4 lb Change: β0.8 lb It's a simple way to understand your progress without getting distracted by every weigh-in. Then explain the differentiation explicitly A DIFFERENT WAY TO LOOK AT YOUR WEIGHT Many weight apps focus on a rolling trend based on recent weigh-ins. Trendio takes a simpler approach: one clear average for each week, compared with the week before. That means you can look back over your progress and easily understand what happened each week, whether your weight went down, went up, or stayed about the same. No complicated trend lines to interpret. No obsessing over individual numbers. Just a clear week-by-week picture of your progress. This section is important for you. It tells the user why Trendio is different, rather than merely saying that it has averages. SET A GOAL AND FOLLOW YOUR PLAN Trendio isn't just about recording where you are. Set your goal weight and choose your plan start date to give your progress some context. See how much you've lost, how much you have left to go, your current pace, and your projected goal date. Your progress becomes something you can actually follow, not just a collection of weigh-ins. GET INSIGHTS THAT ACTUALLY MEAN SOMETHING Trendio turns your weekly data into simple, useful insights about your progress and pace. Instead of asking βWhat does this number mean?β, you can see how you're progressing toward your goal and where your current trajectory could take you. TRACK YOUR WAY Add your weight whenever you step on the scale, once a day, a few times a week, or whenever works for you. Trendio handles the averaging automatically. Prefer not to enter your weight yourself? Apple Health integration lets Trendio import your weight automatically, making tracking effortless. SIMPLE BY DESIGN Trendio isn't a calorie counter, meal planner, or complicated diet program. It's a focused weight-tracking app built around one simple idea: make it easy to understand your progress. See your weight week by week, understand your trend without daily noise, follow your goal, and get useful insights along the way.
