FitCurve is a tool focused on weight, body composition, and long-term change management. It doesn't just record numbers but helps you better understand your body journey through charts, trends, photos, and life status associations.
■ Recording: More than just weight
It takes only seconds each day to record weight, body fat percentage, and BMI. It also supports 6 types of body circumferences, namely chest, waist, hip, thigh, calf, and upper arm, with the option to record the left and right sides separately for each body part; you can also add five levels of mood, text logs, photo captions, and recording sources. All body data recording can be used for free.
■ Charts and Body Profile: See real changes
The super chart plots each data point as a time series, and the body fat and BMI mini charts present the changes in body composition synchronously. The Pro trend regression line can filter out daily fluctuations and unlock longer time ranges, landscape viewing, and two-finger zooming. The body profile also provides circumference trends, body composition radar, BMR/TDEE, and optional blood pressure information after authorizing Apple Health.
■ Calendar and Body Epoch: See the whole process from one day
The monthly calendar marks daily changes with colors, and recent months also allow viewing of monthly summaries and weekly statistics. The body epoch presents key nodes such as starting point, peak, trough, current, and target on a timeline. Pro can review longer histories, customize the observation period, create fun monthly and annual reports, and view gentle target predictions based on recent trends.
■ Body Status: Put weight back into the context of life
After authorizing HealthKit, FitCurve can read sleep, step count, activity calories burned, and exercise records from the iPhone and Apple Watch. Weekly comparisons help you see recent rhythms; Pro's dual-axis charts, scatter plots, and insight cards further show the contemporaneous relationship between these data and weight changes. Modules can be freely sorted or hidden.
■ Optional GLP-1 Medication Record
Record the course, injection date, dose, package, injection site, and daily feelings as they actually occur, support backfilling historical records, local reminders, ending the course, and long-term archiving. The drug and package catalog can be adjusted according to the Chinese, US, or international markets. Pro can compare consecutive dose phases, the 1 - 7 days after injection, and personal trends before, during, and after medication. The relevant content is only for personal records and observations, does not provide medical advice, nor does it judge causality or treatment effects.
■ Body Shape Photos and Time Machine
The silhouette camera provides composition guides for front, side, back, and full-body photos respectively, making it easier to maintain consistency on different dates. The photo time machine can review records by time; Pro can create time-lapse videos with date and weight markings, drag and compare photos before and after, and use the photo wall to organize the journey.
■ Goals, Sharing, and Professional Reports
After setting a target weight and reference date, you can view the basic progress and retain the history of completed or ended goals. Pro unlocks time/weight dual progress, pace, and prediction. 8 sharing cards cover scenarios such as concise data, monthly reports, achievements, perseverance, and goal journey, with 2 of them available for free; Pro also offers more templates, color schemes, privacy options, and social copy. The professional report center includes 5 types of PDF templates, namely concise summary, detailed progress, medication communication, lifestyle, and photo progress, supporting 3 styles, color or black and white, custom dates, preview, printing, and sharing.
■ Privacy, Export, and Cross-Device Sync
There is no need to create a FitCurve account. Body records are saved on the device by default and can be synced across multiple devices through the private database of the current system's iCloud account. It supports Face ID / Touch ID app locks, complete deletion of personal data, and CSV export available to all users. HealthKit permissions are completely optional.
■ 20 Sets of Themes and 11 Widgets
The theme studio provides 20 sets of themes, 4 of which are free; Pro can also set official or custom startup greetings and choose to fix, randomize, sequence, or change them regularly. 11 iOS desktop widgets cover information such as progress, 7-day trends, goal rings, calendars, continuous records, journeys, comparisons, and next injection, with some advanced widgets belonging to Pro.
