# Undiet: Weight Journey Tracker — Progress photos, diets, people > Progress photos, diets, people (iPhone/iPad app by Krnic.) - Source: https://appshunter.io/ios/app/undiet-weight-journey-tracker/id1490849895 (this page in markdown: same URL + `.md`) - Developer: [Krnic](https://appshunter.io/developer/1803578555) - Category: Health & Fitness, Lifestyle - Price: Free with in-app purchases - Age rating: 17+ - Requires: iOS 15.1 · 43 MB - Languages: American English - Released: 2020-01-14 - Data updated: 2026-10-26 ## What is Undiet? Undiet is a private tracker for your weight journey and a community of people walking the same road. Log how your day went, keep progress photos in a vault that never leaves your phone, mark which diet or treatment you are on, and see what actually works for you. NEW IN UNDIET 2.0 Undiet has been rebuilt from the ground up. If you used the original Undiet with an email account, sign in with the same email and your history comes along. The photo tracker is back, now with a locked vault and side by side compare, joined by a diet catalog, a community and a calmer way to log your day. YOUR PHOTOS STAY ON YOUR PHONE Progress photos are stored only on this device, behind Face ID or your passcode. They are never uploaded, never shared and never used to train anything. Not even we can see them. Line up front and side photos from any two dates and watch the change. EFFORT, NOT CALORIES No food database, no barcode scanning, no counting. Each day you log your weight and how much effort the day took, in a couple of taps. Over weeks the graph shows the trend, and the streak rewards showing up, never the number on the scale. ONE TIMELINE, ANY DIET Pick what you are on from a catalog of eating patterns and treatments: Mediterranean, keto, low carb, intermittent fasting, calorie counting, vegetarian, high protein, GLP-1 therapy (semaglutide, tirzepatide, liraglutide) and dozens more, or simply no diet, just tracking. Switch any time. Your journey becomes a timeline of periods with the weight curve over all of them, so you can see what worked for you and what happened after you stopped. GLP-1 DIARY On medication? Record doses, appetite and how you feel through titration, therapy and the maintenance phase afterwards. It is a diary, not a dosing guide: always follow your doctor. PEOPLE ON THE SAME ROAD Your journey is private. The Community is a separate space under a nickname: share a check in, ask a question anonymously, send a word of support. Supportive reactions only, no downvotes, and photos can never be posted. Report and block are one tap away and every post is moderated. YOUR DATA IS YOURS • Progress photos never leave the device • Nickname only in the community, no real names • No ads, no data selling, no tracking across apps • Export everything or delete your account in two taps, from inside the app UNDIET PLUS Tracking, the catalog and the community are free. Undiet Plus unlocks unlimited photo history, your full weight trend over all time and the stats for every diet period. Auto renewing subscription: EUR 6.99 per month or EUR 39.99 per year with a 7 day free trial on the yearly plan (prices may vary by country). Payment is charged to your Apple ID at confirmation of purchase or when the trial ends. It renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel it in your App Store account settings. Undiet does not give medical or dietary advice and is not a substitute for your doctor. The catalog describes diets and treatments neutrally so you can record what you are on. Undiet is for people aged 16 and over.
