The fields that do not apply
Half the screen of an injection tracker is meaningless for a tablet. There is no injection site, no pain score, no rotation, no clicks and no pen to discard. Asking for them anyway is how an app tells you it was not built for what you are doing.
In Penwise, oral medication is a route rather than an afterthought. Choosing an oral dose hides the site and pain fields entirely, switches the schedule from weekly to daily, and changes the supply arithmetic to tablets per pack rather than doses per pen. What is left is what actually matters: the dose, the time you took it, and what happened afterwards.
The fasting window is the thing worth logging
Oral semaglutide is absorbed poorly and inconsistently, which is why the label is unusually specific: take it on an empty stomach after waking, with no more than a small sip of plain water, and wait before eating, drinking anything else or taking other medicines. Get that wrong and the dose you swallowed is not the dose you absorbed.
That makes the time of the tablet genuinely useful data rather than trivia. Penwise records the time you took it, so a run of mornings where the window was rushed is visible instead of forgotten – and a week where the effect seemed weaker has something to be compared against. Confirm the exact instructions for the product you were dispensed with the leaflet or your pharmacist; they vary between products and markets.
Three ladders, and why the milligrams do not match
This is the part that catches people out, and it is worth spelling out. Oral semaglutide now exists in more than one tablet formulation, and a newer tablet that absorbs better reaches the same exposure at a lower number. A 4 mg tablet on the newer ladder is not a smaller dose than 7 mg on the older one – it is broadly the equivalent one.
| Product | Dose steps offered | Cadence |
|---|---|---|
| Rybelsus (current) | 1.5, 4, 9, 25, 50 mg | Daily |
| Rybelsus 3 / 7 / 14 mg (older) | 3, 7, 14 mg | Daily |
| Wegovy tablets | 1.5, 4, 9, 25 mg | Daily |
| Ozempic tablets | 1.5, 4, 9 mg | Daily |
Packs are 30 tablets, so one pack is a month at one tablet a day. The ladders are not interchangeable milligram for milligram – your prescriber decides the equivalent step.
Penwise keeps these as separate products rather than one list of numbers, so a history that spans a switch stays readable. When you move from an older tablet to a newer one, the change is dated and the doses either side are not silently compared as if they were the same scale.
Daily means a different relationship with a missed dose
Semaglutide has a half-life of about a week whichever way it enters you, so a single missed tablet is a small dent rather than a cliff. But dailies are missed far more often than weeklies, and a run of missed mornings adds up in a way a single skipped injection does not.
Penwise schedules reminders months ahead at a time you choose, with a follow-up the next day if nothing was logged, and the calendar shows the gaps rather than hiding them. Over a few months, an adherence pattern – always the weekend, always after a late night – is something you can actually see. Missed GLP-1 doses covers what the different products mean by “late”.
Side effects on a daily schedule
On a weekly injection the useful question is which day after the shot a symptom lands. On a daily tablet, the question moves: is it the dose step, the time of day, or the fasting window that changed.
Penwise tracks twenty named side effects on a 0 to 5 scale and nine sliding measures – appetite, fullness, food noise, sweet, salty and fatty cravings, energy, mood and sleep – against the dose you were on that day. Insights only appear when there is enough of your own history to support them, so the app stays quiet rather than guessing. See the GLP-1 side effect timeline.
Weight, and the level underneath it
Weight, body fat, lean mass, waist and resting heart rate sit on the same timeline as the dose history, with a goal weight and progress against it. Penwise+ also estimates the semaglutide level from your logged doses, which on a daily schedule shows the climb to a plateau after each step more clearly than a weekly one does. The arithmetic behind it is in how long semaglutide stays in your system.
And none of it leaves your phone
No account, no sign-in, no Penwise server holding health data. Everything you log stays in the app on your device, export is free and unlimited, and a backup you export is encrypted on the phone with a passphrase we do not hold.
A tracker that knows a tablet is not a shot
Free core tracker, daily schedule, no irrelevant fields, and nothing sent anywhere.
