About

ProgressLens

Features
Read full description

Your progress photos should make change obvious, not leave you guessing. But when every photo is taken from a different angle, distance, or pose, it is hard to tell what actually changed. When progress photos are mixed into your gallery, forgotten between check-ins, or buried among thousands of images, looking back becomes frustrating. ProgressLens helps you build a clear visual record of your progress. Capture more consistent check-ins, keep photos and body measurements organized by date, and compare two moments side by side to see changes that are easy to miss day to day and help you stay motivated to continue. SEE THE CHANGE YOU ARE WORKING FOR Take Front, Side, Back, or custom-label progress photos and compare the same view over time. Choose two check-ins and see them side by side, so you can look beyond daily fluctuations and recognize real progress. Share a comparison when you are proud of how far you have come, with friends, on your story, or just for yourself. Whether you are losing weight, building muscle, getting back into fitness, or simply tracking your body over time, ProgressLens gives you a clearer way to see your journey. TAKE PHOTOS YOU CAN ACTUALLY COMPARE Random photos taken weeks apart with different angles and poses do not make progress easy to see. ProgressLens helps you create matching check-ins, so you can compare the same angle, framing, and pose over time. Use the camera alignment grid and previous-photo guide to line up each new check-in with the last one. Instead of guessing whether anything changed, build photos that make the change easier to see. Review the photo, date, time, label, and note before saving. Import existing photos when you need to add a past check-in to your record. STOP LOSING PROGRESS IN YOUR GALLERY Your progress photos should not disappear between screenshots, holidays, food photos, and random camera images. ProgressLens keeps check-ins and measurement sessions together in one visual timeline. Browse your history by date, open photos full-screen, and revisit the context behind each entry whenever you need it. TRACK THE NUMBERS BEHIND THE CHANGE Photos show the visual change. Measurements help explain it. Log bodyweight, waist, chest, shoulders, arms, thighs, and more. Save a full body measurement session or quickly record a single value, such as your daily weight. Review past measurements by date and see simple charts as your history grows. MAKE CHECK-INS FIT YOUR ROUTINE Use the default Front, Side, and Back labels, or create custom labels for the views that matter to you. Add a short note to remember context later, such as training changes, a new routine, a milestone, or anything else worth looking back on. PRIVATE BY DEFAULT Your photos and measurements stay on your device. No account is required. Create a local backup when you want an extra copy or need to move your history to a new phone. ProgressLens is a progress photo tracker, body measurement tracker, and visual record of the work you put in. Capture the check-ins. Keep the history. See the change.
