Everything Penwise does.

Logging

The part you touch several times a week, so it is built to be fast.

• Shots in a few taps

  Date, time, medication, dose, site, pain on a 0 to 10 scale, how it felt, and notes. Penwise remembers your medications and doses, so a repeat is quick.

• Oral doses too

  Oral medication is a first-class route. Choosing it hides the site and pain fields entirely, because they do not apply.

• Site rotation that protects skin

  A body map with the site you have used least recently suggested by default, which is the behaviour that actually matters over months.

• Weight and body composition

  Weight, body fat, lean mass, waist and resting heart rate, all charted against your goal.

• Check-ins

  Nine things on a scale, including appetite, fullness and food noise, plus twenty named side effects on a 0 to 5 severity scale.

• Nutrition

  Calories, water and protein, tracked alongside everything else rather than in a separate app.

Understanding

Where a log stops being a list and starts being useful.

• Estimated medication level

  A pharmacokinetic model with real absorption and elimination half-lives, tuned per medication. An estimate from a published model, never presented as a measurement of your blood.

• Adherence

  Whether you are taking doses on time, and by how much you tend to drift.

  Penwise+

• Site comfort

  Which injection sites hurt less for you, based on the pain you actually recorded.

  Penwise+

• Symptom timing

  Which day after a shot a given side effect tends to land, so you can plan around it.

• Charts you can dig into

  Ranges from one month to all time, with pinch to zoom revealing more of your history rather than interpolating it.

• Quiet until it is sure

  Every insight has a minimum amount of your own history it needs before it appears. Penwise would rather say nothing than invent a pattern.

Pens and supplies

The awkward, specific knowledge that separates a real tracker from a date picker.

• Seventeen pens, five vial presets

  Ozempic, Wegovy, Mounjaro, Saxenda, Victoza, KwikPen and FlexTouch variants, plus compounded vials.

• Click counts that are actually right

  A click moves a fixed volume, not a fixed number of milligrams, and on some pens the count changes with the dose step. Penwise knows the difference.

• The extra dose, and when there is not one

  Some pens leave a usable dose at the end. The redesigned Lilly pens finish closer to empty and no longer do, and Penwise does not pretend otherwise.

• Discard windows

  Every product stays good for a different number of days once started. Penwise counts it down for you.

• Days of supply

  How long your current stock lasts at your current dose, so a refill is never a surprise.

• Schedule you control

  Skip, postpone or reschedule any dose, with a record of what you decided and why.

Connected

Everything on-device or routed through the platform health stores, never through us.

• Apple Watch and Wear OS

  Both included, no extra purchase. Log from the wrist, see your next dose, and capture your resting heart rate after a shot.

• Apple Health and Health Connect

  Weight, body fat, lean mass, water, nutrition and resting heart rate, synced incrementally.

  Penwise+

• Home screen widgets

  Your next dose, your weight and your streak, on both platforms, plus shortcuts to log without opening the app.

• Reminders that keep working

  Months of doses are scheduled ahead, so reminders keep arriving even if you stop opening the app.

• Doctor-ready PDF

  A report you can hand over at an appointment or send ahead of one.

  Penwise+

• Import from Shotsy

  CSV or backup, in a couple of taps, with no duplicates on a second import and a full rollback if you change your mind.

  Penwise+

Yours

Privacy, control and the ability to leave with everything you put in.

• App lock

  Face ID, Touch ID, fingerprint or device passcode, with the screen shielded before the system takes its app-switcher snapshot.

• Screenshot blocking

  On Android, screenshots and screen recording are blocked while the app is locked.

• Encrypted backup

  An encrypted backup file you export yourself and keep wherever you like. The passphrase is yours alone.

• Full export, free

  CSV and JSON of everything, forever, with no paywall on your own history.

• Make it yours

  Seven accent colours plus a free colour picker, light and dark, and true AMOLED black. The app icon follows your choice.

  Penwise+

• Four languages

  English, Slovak, Czech and Polish, complete from day one, with proper diacritics throughout.
