An offline log for GLP-1 doses and weight, for tablets or injections. No account, no cloud, no ads. Plainlog records your GLP-1 doses and the weights you log, and shows them back to you. TABLETS AND INJECTIONS, BOTH PROPERLY If your medication is a daily tablet, you get a screen built around today. If it is a weekly injection, you get one built around your next dose and the days between. Injection-site logging appears on a dose only when that dose's medication is an injection, so a switch leaves your old injectable entries with their sites intact. LOGGING TAKES SECONDS Open, tap, done. Forgot to log something last week? Enter it for any past date, with the real time of day, in a few taps. REMINDERS YOU SET Switch reminders on and pick a time of day. They fall on the days your own schedule already produces, and one you have logged is not repeated. Reminders are local notifications on this phone, and Plainlog asks for notification permission only when you switch one on. ESTIMATED LEVELS A Plainlog+ chart draws an estimated level over time from the doses you have logged and published pharmacokinetic averages. It is an estimate, not a measurement, and the screen states what the estimate cannot tell you and which sources its numbers came from. WEIGHT FROM APPLE HEALTH Plainlog+ reads weights you already have in Apple Health into your log. Weight only, opt in, and off until you turn it on. SWITCHING MEDICATION? YOUR HISTORY STAYS One medication at a time. If you switch, tablet to injection or back, Plainlog keeps the full record of both on one timeline. THERE IS NO SERVER There is no account to create and no server to send anything to. Your record lives in one file on this device. TAKE IT WITH YOU Export your log as a CSV any time — free. A PDF of the doses and weights you logged is a Plainlog+ feature. ONE SUBSCRIPTION, NO ADS Plainlog+ is an auto-renewing subscription, annual or monthly, at the price shown on this page. There are no other tiers, no advertising and no analytics. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ WHAT THIS APP DOES NOT DO It does not recommend doses or tell you when to change one. It is a record, not advice, and it is not a substitute for your prescriber.
