Vialog: Peptide Journal

Injection tracker & reminders

Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.

No account, no server, no subscription. Your injection records stay on your iPhone and Apple Watch, with reminders at your times and a PDF for your appointment. Vialog is a private peptide and injection journal. Remember when, where and how you felt. No account. No subscription. You bring the names, quantities and schedule for the routine you already follow. Vialog keeps the record. It never selects a product, calculates a dose, suggests a site or recommends a change. It organizes what you enter and reminds you at the times you set. WHAT IT DOES • Keeps your routines. Name each one yourself, set the times and days, and enter the planned amount in the units you already use. Nothing is looked up, suggested or converted. • Reminds you, your way. A reminder at each scheduled time or a set time before it, and a second one afterwards if you want it, set per routine. Delivered by iOS on the device. By default a reminder says only that you have a scheduled entry; the routine's name and amount appear on the lock screen only if you turn that on. • Records in seconds. Confirm the amount, pick a site if you like, add a note or a photo. The body map shades each position by when you last recorded there — a record of where you have been, never a suggestion of where next. • Keeps a journal. Check-ins on energy, sleep and appetite, symptoms in your own words, body measurements (weight, body fat, lean mass) and lab results in your own words and units. The last 30 days at a glance; new answers always start blank. • Shows your plan over time. Each routine's screen draws the planned amounts you entered over time with your records on them, and its last four weeks day by day. Today shows the week, and last week in plain counts. • Shows your history. Every record by day in the Journal, with filters and search. Review injections, check-ins, body measurements and lab results on a shared time axis, each in its own lane; see symptoms on a calendar, set two periods side by side, and save a review for your next appointment — a record of what happened, without treatment assessments. • Counts what you hold, if you ask it to. Enter the amount you have on hand and see what it covers, counted down by your own records. It reports a count and a day; it never prompts you to obtain anything. • Works where you are. Home Screen and Lock Screen widgets show the day's entries and the next; Siri and Shortcuts record one after you confirm; the Apple Watch app records or skips an entry at the amount you planned. • Leaves with you. Import injection or body measurement history from CSV. Export CSV or prepare a PDF with selected records and your own appointment questions. Back up to a file, restore on a new phone, or delete it all. PRIVATE BY DESIGN Vialog has no server, so there is nowhere for your records to go: they are written to your iPhone and stay there, apart from what your own Apple Watch is shown if you use the watch app. Widgets and the watch name a routine only if you turn that on. No sign-up, no ads, no analytics, no tracking. Optional App Lock asks for Face ID, Touch ID or your passcode before the app opens, and shows a blank cover in the app switcher. If you want it, Vialog can share weight, body fat and lean mass with the Health app — both ways, and off until you turn it on. Nothing else is shared: not your routines, quantities, sites, notes, check-ins or lab results. FREE, WITH ONE OPTIONAL PURCHASE Recording, reminders, the journal, history, injection sites, App Lock, CSV export, backup, restore and deleting are free and stay free, and so are your first three routines. Vialog Pro is a single purchase, not a subscription, and adds four things: more routines, the amount on hand, Review (any range, body measurement and lab result lanes, the calendar and the comparison; the Journal's last 30 days stay free), and the PDF report. Anything you already have keeps working whether or not you buy it, and Family Sharing is on. Vialog is a personal record. It does not recommend products or changes to treatment. If something about your routine should change, that is a conversation with the person who prescribes it.

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

New in 1.4: Vialog is made for iPhone Duo. Opened out, Today, the Journal and Routines sit in two columns, and held half open, nothing is drawn across the fold. Settings › Diagnostic Report keeps a short log of problems the app ran into, on this iPhone only. It holds none of your records and leaves the device only if you share it yourself.
