What’s new

Every release, what changed in it, and why it changed.

Logbook has no analytics and no crash reporting, so this page and the support inbox are the whole conversation. If something here does not match what your copy does, the version is at the bottom of Settings → About.

iPhone is on 1.5.3, Android on 1.5.2; 1.5.3 fixes something only the iPhone build had. From 1.5.2 on, a version number means the same build on both stores; it just may not arrive on both the same day, because each store reviews on its own clock and a finished build ships as soon as its store clears it. Before 1.5.2 the numbers themselves drifted apart, which is why some versions below reached only one store. Every entry below names the store it went to and carries that store's own release date. A version that is on only one store says so.

1.5.3 Latest

App Store — September 24, 2026Not on Google Play — the Android app never had this problem.

iPhone only, and one fix.

  • The Developer section is gone from Settings. It is a testing menu that was never meant to ship, and 1.5.1 and 1.5.2 included it by mistake. If you used “Insert sample data…” from it, that sample data is still in your log and updating does not remove it: delete those entries by hand, or, if you have nothing else in the app yet, use Settings → Data → Delete all data. If you turned on premium from that menu, it is off again now.

1.5.2

App Store — September 24, 2026Google Play — September 23, 2026

One change, and the first version built from the same code for both stores.

  • “Log food” now sits at the top of the Food tab. It used to be a small text link in the header of today’s food list, below the charts, and someone could not find it. It is now a full-width button at the top, and the one by the food list is still there, now a real button that is easier to spot.

1.5.1

App Store — September 21, 2026Not on Google Play under this number, and it will not be: Android already has both fixes below, inside 1.5.0.

Everything in 1.5.0, plus the two fixes that landed on Android hours after the iPhone build was cut. Nothing else changed.

  • On a shot day the medication level chart dropped today’s dose. Once the dose’s time of day had passed, the chart drew a week of decline and a rise seven days out, while the Today screen said a shot was due now. Nothing you logged was affected, only what the chart drew — but if the chart looked wrong to you on a shot day, that is what it was.
  • Your preferred injection time can be changed. Onboarding asked for it and then nothing could edit it, so the only way to set one afterwards was to start onboarding over. It now sits in the schedule editor, and can be cleared back to no preference.

1.5.0

App Store — September 20, 2026Google Play — September 20, 2026

A release about keeping things: cards worth saving, measurements that add up to something, and a weight chart you can read a number off.

  • Save a journey card and come back to it. Yours is still there, still free, and still the one that follows your latest numbers. Beside it you can now keep named cards — a card for a milestone, a card for a particular photo pair — renamed or deleted by holding one down. Keeping more than Yours is part of Premium.
  • Measurements add up now. There is a total change across every site you track, each site reads as start against now, and History is a table you can run your eye down instead of a sentence per entry — tap a row for that site’s chart. Progress shows the sites you actually measure. The seven tabs are gone.
  • A measurement session can be backdated or corrected. If you measured on Sunday and logged it on Tuesday, say Sunday; if a number was wrong, open the session and fix it in place.
  • The weight chart and the Today sparkline are the same chart now. The sparkline spans your whole journey rather than a fixed recent window, there is a tick for each shot in your dose colors, and a legend for the marks that do not explain themselves.
  • The weight chart’s scale now steps to fit your data — which means a line you have looked at before may sit differently on the chart. Nothing you logged changed; only the scale it is drawn against did. Worth one look if a trend seems to have shifted.
  • A long gap with no weigh-in breaks the line instead of drawing through it. More than four weeks without a reading and the line stops and restarts, so a month away no longer renders as a smooth slope you never walked. A stranded reading keeps its dot.
  • Your journey card keeps its photos. Before & after photos, zoom, covers and weights were lost the moment you left the screen, so the card had to be rebuilt every time.
  • A zoomed photo lines up on the card the way it did in the sheet. It was landing higher than where you placed it, which could cut off the top of a head. If you shared a card with a zoomed photo before this release, it is worth a second look — what you shared may not have been framed the way you set it.
  • Undo waits eight seconds instead of four. The bar was timing out while you were still reaching for it, which looked like Undo doing nothing at all — it is still on screen as it slides away. Every undo works this way now: food, meals, shots, measurements and weight.
  • Today rolls over at midnight without being reopened. Steps and the weight range were still reading yesterday’s day if the app had been left open across midnight.
  • Google Play here, and iPhone in 1.5.1 above — on a shot day the medication level chart dropped today’s dose. Once the dose’s time of day passed, the chart drew a week of decline and a rise seven days out, while the Today screen said a shot was due now. Nothing you logged was affected, only what the chart drew — but if the chart looked wrong to you on a shot day, that is what it was.
  • Google Play here, and iPhone in 1.5.1 above — your preferred injection time can be changed. Onboarding asked for it and then nothing could edit it, so the only way to set one afterwards was to start onboarding over. It now sits in the schedule editor, and can be cleared back to no preference.

1.4.0

App Store — September 18, 2026Google Play — September 20, 2026

A release about the journey as a whole: where it started, and something to show for it.

On iPhone this follows 1.2.0, so it also brings everything in 1.3.0 below — the tablet wait on Today, the weight line colored by dose, BMI on Progress, and the two new Insights. The one exception is the syringe-units fix, which belongs to a calculator that is on Android only.

  • Share your journey. A card of your progress — weight trend, doses, goal and photos — arranged the way you want and ready to post. Before a Before & after photo leaves your phone you can cover or blur parts of it. The card is made on your phone, and nothing is sent anywhere until you share it yourself.
  • Your older weight history, from Apple Health. It used to stop at a year back. Now all of it shows in your history, and your journey starts on the date you say it did, so years of scale readings from before treatment stay out of your stats, badges and journey card.
  • The weight chart has a scale, so a line can be read as a number and not just a shape.
  • Today’s activity card adds workout minutes and a 7-day step chart.
  • If you ever changed your dose day, your streak and missed doses are now counted correctly. Doses from before the change were being judged against the new schedule, so an on-time dose could count as missed and break a streak. Those numbers correct themselves; nothing you logged was changed. It is worth another look if a streak or missed-dose count seemed wrong.

1.3.0

Google Play — September 12, 2026Not on iPhone under this number. Everything here except the syringe-units fix reached iPhone in 1.4.0 above.

A release about the tablet, and about seeing the medication in the numbers around it.

  • If you take a tablet, Today knows you cannot eat yet. Rybelsus and the Wegovy tablet are taken on an empty stomach with a wait before food, water or anything else. Today now shows when that wait ends, with a countdown you can turn on if you want one.
  • Your weight line is colored by the dose you were on. Where the dose changed, the chart changes with it, so a titration step and what followed it are one picture rather than two.
  • Progress shows BMI, and reads more clearly. BMI is given as a number and a change rather than a category, next to a tidier set of results.
  • Insights: weight at each dose, as a table — every dose you have been on, in order, with what the scale did on it. And side effects set against the fiber and water you logged the day before, which is the pairing people are usually told to watch. Both are part of the optional unlock.
  • Syringe units follow the vial you actually picked. The calculator could keep the previous container’s concentration after you switched, so the units to draw were computed from the wrong vial. If you use that screen, it is worth re-checking any figure you wrote down before this release.
  • Daily-dose streaks count properly, and large text fits in the places it was being clipped.

1.2.0

Google Play — September 7, 2026App Store — September 17, 2026

A release about starting weight, and about screens telling the truth about their own numbers.

On iPhone this is the first release, so it is also everything below it. 1.0.0 and 1.1.0 never shipped on the App Store as their own versions — their entries are the rest of what a new iPhone install has. Two differences are worth knowing. The built-in syringe and reconstitution calculator is on Android only, along with every reading given in U-100 units: the App Store allows a medication dosage calculator only from the drug’s manufacturer or an approved institution, and Logbook is neither. The calculator on this site does the same arithmetic in any browser. Everything else — doses, supply, weight, food, photos, insights, backup — is the same app on both. 1.3.0 above reached iPhone as part of 1.4.0.

  • Your starting weight carries the date it was measured. If your history came in from Apple Health or Health Connect and your real starting weight predates it, there was nowhere to say when that number was from — so it landed on the first day of your history and replaced the earliest weigh-in you had. It is now entered with its own date, from one place, and it never overwrites a reading you actually took.
  • The starting weight appears at the end of your weight history, marked as stated rather than measured, so the chart and the list no longer begin on different days with nothing joining them.
  • A milestone names the line you crossed, not the range it landed in. At 213.5 lb the card read “Into the 200s” while counting down to 210, which was wrong twice over.
  • The water field asks for the unit you chose. It was labeled “ml” no matter what — so on ounces, typing 8 for a glass logged about a third of one. What was stored was always correct for what was typed; the label was the lie, which is why it survived so long. Worth a glance at any water entry that looks too small.
  • A food you typed in says so. Entries made by hand were being credited to a barcode scan or to the built-in database, depending on which way you reached the sheet. They now read “Entered by hand”, and re-logging keeps whatever the original entry really was.

1.1.0 Android

Google Play — August 27, 2026Never shipped on the App Store under this number — everything in it is in 1.2.0 above, which is the first iPhone release. The syringe-calculator items below are the exception: those are Android only.

A release about supply: knowing what you have left, and not having to do arithmetic to find out.

  • Supply moved to the Dose screen. What you have left and the syringe calculator are now where you go to take a dose, rather than buried in Settings. Logging a shot lets you say which container it came from, and that choice carries over to the next one.
  • Vials, pens and packs. A container is now whichever of those it actually is, worked out from your medication and changeable if it guesses wrong — so a pen box reads as a pen box instead of as a vial.
  • Expired containers are offered, not hidden. If a dose came from one, you can still say so. Logbook records what you did; it does not decide for you what you are allowed to have done.
  • Tap common vial sizes and water volumes in the syringe calculator instead of typing them. They fill the field and nothing more — an unusual vial typed by hand works exactly as before.
  • Run-out dates count whole doses only. A vial that divides unevenly used to be projected as though the leftover fraction were a dose you could draw, so the date sat a few days later than the supply really lasted. A remainder under one full dose now reads “Under 1 dose left” with no date beside it, which is the honest answer.
  • A vial that held more than its label can say so. Compounded vials are often filled past the number printed on them, so one that reads empty may still have a dose in it. Record what a container really held — entered as what is left now, and worked backwards — and the extra dose is credited to the container it actually came from rather than quietly charged to the next one.
  • Dates no longer shift by a day around daylight saving. Several places worked out “today” from UTC rather than from where you are, which put a dose, a weight or a day’s food on the wrong date twice a year and at either end of a long trip.
  • Nothing is cut off at the bottom any more. On phones with gesture navigation, panels that slide up from the bottom put their button underneath the navigation bar whenever the keyboard was down. Reported by a tester, and it affected every one of them.
  • Health data refreshes when you come back to the app — so a weight that arrived in Apple Health or Health Connect while Logbook was in the background shows up when you return, instead of on the next cold start.

1.0.0 Android

First release — Google Play, August 27, 2026Never shipped on the App Store under this number — the first iPhone release is 1.2.0 above.

The first public version. Everything below was in it.

  • Doses — medication, schedule, injection site rotation and supply on hand, for a pen or a tablet.
  • Weight and measurements — with goals, trends and progress badges.
  • Food, water, protein and fiber — against an offline database, with optional barcode scanning.
  • Side effects — a daily log with a severity scale and your own notes.
  • Progress photos — with alignment and side-by-side comparison.
  • Reminders that never name a medication, a dose or a weight on your lock screen.
  • Apple Health and Health Connect — read-only, optional, and never written back to.
  • Export and backup — CSV, JSON, a PDF summary for your clinician, and a full backup file you hold yourself.

What has never changed, and will not. No account, no cloud, no analytics, no crash reporting, no ads. Two optional features can reach the internet and each has its own switch, both off until you turn them on. The privacy policy has the detail.
