Why Onward

Made by someone living with CML, for the road we're all walking.

Onward began as a personal way to keep track of life with chronic myeloid leukaemia: the appointments, the blood counts, the BCR-ABL numbers slowly heading the right way. After looking for an app that could hold all of it, gently and privately, and not finding one, it became this. Every screen on this page is real.

Your results

Watch your response find its way down.

Every BCR-ABL result on one chart, on the logarithmic scale your team uses, with MR2, MMR, MR4 and MR4.5 marked so you can see exactly where you sit. Onward tells you which way it's moving, and by how much.

  • Molecular trend: your whole history on one chart, with the milestones marked.
  • Blood health and chemistry: every marker against its normal range, or your own lab's.
  • Clinic letters and reports: keep the PDF from a visit with that visit's results, and build a report to hand to your team.

A logarithmic chart of BCR-ABL falling from near 100 percent down to 0.03 percent, with dashed guide lines marking MR2 at 1 percent, MMR at 0.1 percent, MR4 at 0.01 percent and MR4.5.

In plain English

Nobody hands you a glossary on day one.

Haemoglobin, neutrophils, ALT, bilirubin, MR4. Tap any of them for a short, jargon-free explanation of what it measures and why your team is watching it.

No searching, no medical dictionary. Just the numbers Onward already tracks for you, explained in the language you'd actually use.

The In Plain English guide, listing haemoglobin, white blood cells, neutrophils, platelets, ALT and other markers with one-line explanations.

Day to day

It counts your tablets so you don't have to.

Mark today's dose with a tap and build a streak. Tell Onward how many tablets you have and it works out when you'll run out, then checks that date against your next appointment.

If your supply won't last, it says so early enough to do something about it.

  • Run-out forecast: checked against your next clinic date, with a nudge to order a repeat.
  • Apple Health: already logging doses there? Onward reads them in, so you never log twice.
  • Widgets: today's dose and your next appointment on your Home and Lock Screen.
  • A full history: every TKI, dose change and pause, with how long each one lasted.
  • Reminders before clinic: a nudge the day before a visit or PCR test, or up to a week ahead, at a time you choose.
  • Questions for your care team: jot down what you want to raise, tick each one off once asked, and it stays linked to that visit. Newly diagnosed? Start from a set of common ones.

On your terms

Track what matters to you. Nothing else.

“When I started looking for an app to track my CML, a lot of them were clinical. They'd ask about side effects, and I didn't know what to put in which box from one day to the next.” Darren, who built Onward

So in Onward, none of it is compulsory. Side effects and how you're getting on, your mood, walks and runs, steps and sleep. Each one is a switch you turn on if it helps, and leave off if it doesn't. Log a lot, log a little, or log nothing but your results. It's a record for you to look back on, not a form to fill in.

Your story

More than a set of numbers.

Alongside the results, Onward keeps the moments. The first long walk after treatment started. A holiday you weren't sure about booking. Add a few words and some photos, and they take their place in a timeline that fills out year by year.

Milestones are marked as you reach them. And on each anniversary of your diagnosis, Onward gathers the whole year into a single page: how far your response travelled, the milestones you passed, every clinic visit and blood test, the days you took your tablets, and anything that changed about your treatment or your care team.

A moment, kept

A Year in Review page covering a first year on treatment: BCR-ABL moving from 63 percent to 0.07 percent, MR2 and MMR reached, 13 clinic visits, 12 blood tests, and medication taken on 98 percent of days.

Your first year, on one page

On iPad

Your journey, as a book you can turn.

Turn an iPad sideways and the Journey stops being a list. It becomes a bound book, a page for each chapter of your story, opening on a cover that reads "My Journey" until you put your name in.

A clinic visit written as a book page, with the date handwritten at the top, the clinic letter clipped beside it, a BCR-ABL result of 26.83 percent shown against a falling trend line, and blood counts drawn as gauges against their normal ranges.

A clinic visit, written out rather than listed

Visits earn a page by mattering. A new result, bloods out of range, a note, a change of dose. Blood counts are drawn as gauges, so where the dot sits tells you the story before you read the figure. The quiet runs where nothing changed are gathered onto one page that says so plainly, because years of good news should read as good news rather than as a gap.

Moments become scrapbook pages, photos printed large with white borders, the real workout on a sticky note beside them if Apple Health is connected.

A personal moment as a scrapbook page: photographs of a coastal walk printed large with white borders, a handwritten note underneath, and the real workout on a sticky note showing 11.1 miles in 3 hours 53 minutes.

A diary that doesn’t know the ending.

Every page keeps to what was true on the day it describes. The day your dose changed does not know how long you would be on the new one. Nothing reaches forward to tell you how something turned out, because on the day itself nobody knew. It is the difference between a book written as you went along and a report put together afterwards.

Hand someone your iPad, not your records.

Hold the leaf for five seconds and the book locks itself. Tabs gone, nothing editable, every link dead. Whoever is holding it can turn pages and nothing else.

The cover in reading mode

One app, no extra purchase. Every other screen is rebuilt for the space too. The book needs a big screen turned sideways, so that is where you will find it.

When things change

And if you ever stop treatment.

Onward has an information-only guide to treatment-free remission, built around the European LeukemiaNet 2020 criteria, showing how your own situation compares and giving you questions to take to your next appointment.

If you and your team do stop, the app changes with you. Daily dose tracking pauses, monitoring moves to the closer schedule, and Onward starts watching your results in the other direction.

Information only. Stopping treatment is a decision for you and your care team, never something to act on from an app.

Onward has no accounts, no logins and no tracking. Your information stays on your device, and syncs across your own devices only through your private iCloud. Never to us. Never to anyone else.

  • On your device, behind Face ID if you want it.
  • Your own iCloud, optional sync you can switch off at any time.
