Retain 2.4 is a new notebook for the same logs. • Today opens on a dial: the grams left to the protein floor you set, with Log protein and your usual meals one tap away. • Muscle signals: days at your floor this week, lifting sessions against your weekly target, and lean mass beside weight once you have both. • Say "Log protein in Retain" to Siri, or put it on the Action button. • One-page appointment summary: protein days, meals, weigh-ins, lifts, side effects, dose dates and your questions, as a PDF. • Learn cards for the medicine you logged, from glp1base.com. • Night mode. Retain follows your iPhone, or pick Paper or Night in More. • Retain Pro can now be bought once, as Lifetime. Plans are unchanged and still include photo scanning. Your logs, protein goal and weight units carried over unchanged.

Small, honest fixes to the Retain Pro screen: • If subscription plans can't be loaded, Retain now tells you what actually happened instead of blaming your connection. • "Try again" visibly checks with the App Store and reports back — including when plans are still unavailable. • After a retry succeeds, your plan is preselected so subscribing stays one tap. • The sample-data tour no longer surfaces raw App Store errors.

This update is about trying before paying, and about privacy on shared screens: • Try the plate-photo scanner free: signed-in users get 3 sample scans — the same honest, editable ranges Pro uses, no payment first. • New App Lock: require Face ID, Touch ID, or your passcode to open Retain. • A privacy cover now hides your data in the app switcher, and lock-screen reminders no longer mention medication at all. • If you start a free trial, Retain sends a heads-up about two days before it converts — a renewal never surprises you. Trial wording now only appears when a trial actually applies to you. • The daily photo-scan fair-use limit is stated plainly on the Pro screen. • Share a no-shame progress card from Trends — your protein streak and effort, never your weight or medication. • New optional daily protein-floor check-in and a Sunday weekly recap — invitations, never guilt trips. • Doctor-visit reports now include a small provenance footer.

Retain is now clearer about what it records, what it estimates, and what stays under your control: • Confirm a recent or favourite meal and log it again in one tap, with Edit first and Undo. • Manual meal entry, on-device nutrition-label reading, and barcode lookup are clearly separated from Pro plate-photo estimates. • Plate-photo results use editable calorie and macro ranges with confidence—not fake precision. • Strength, lean-mass, and weight trends are easier to review together. • Dose and injection-site history is record-only; Retain does not suggest a next site or any treatment decision. • Progress photos use a neutral date-based timeline. • Export and import now include live records and progress photos in a versioned archive that is clearly identified as sensitive; demo and deleted records stay excluded. • Account deletion remains available inside the app. Retain remains a tracking and education tool, never a source of dosing or treatment advice.

What's new in 2.0 — a big, free upgrade: • Photo food logging — snap a meal and get honest calorie and macro ranges (Pro), with one-tap corrections that learn from you. • Protein floor — set a daily protein floor from a cited guideline range to help protect muscle; celebrated when you hit it, never shamed when you don't. • Injection-site body map with rotation history and a next-site suggestion (free). • One timeline for your shots, food, weight, and side effects — log 18 common symptom types and see them next to your shots. • Plateau and come-off support for the moments that matter most. • Honest weigh-in trend with a noise band, plus Apple Health weight sync. Everything you already use stays free, and your data hasn't moved. As always: tracking and education only — never dosing advice.
