Simulated demo, built from the app’s screens
How voice logging works
Hold the mic. Say the set. Let go.
Margin only listens while you hold the button. It reads what you said on the phone, shows you the numbers, then logs them.
This is a simulation made from Margin’s screens, not a screen recording. No microphone needed to watch it.
Between sets
Last time’s numbers are right there.
Each exercise shows what you lifted last session, so you know what to beat. When you’d rather tap than talk, the steppers and keypad are always on screen.
- What you did last timeEvery set from your last session, on the same screen as today’s.
- Steppers and a keypadNudge the weight by 2.5 kg or type the exact number. Voice is optional.
- A rest timer that stays out of the wayIt sits above the inputs. Add or remove 15 seconds, or skip it.
- Your routine, your exercisesMargin follows the plan you already have. It doesn’t hand you a programme.
Try it: tap the numbers, the steppers or Log set.
Next-set suggestions · Pro
A suggested next set, with the reason.
Pro fills in the weight and reps for each set from your history and your training goal. One line under the steppers says why. You can always change the numbers.
80 × 10, 10, 10 last week with reps left. Up to 82.5.
Why ›Recovery and your week
See what’s recovered, and how your week went.
Margin estimates recovery for each muscle from the sets you log and what you tell it. Every Sunday it writes a short summary of your week in plain sentences.
One tap tunes how fast your chest recovers in Margin’s estimates.
Part of the muscle sheet in the app. Try it.
Recovery is an estimate
It comes from the sets you log and your answers to “Still sore” or “Feels fine”. Look ahead a few days to see which of your plans fits. It’s a guide for planning, not a medical measurement. Pro explains each estimate and tunes it to you.
You trained 4 times and logged 68 working sets. Bench press and squat both went up. Overhead press has stayed at 50 kg for three weeks. Back got 7 sets, the fewest of any muscle.
A weekly summary you can read in a minute
What went up, what stalled, which muscles got the fewest sets, and one change for next week that you can apply to your plan or ignore. Free shows the headline. Pro shows the full summary.

Questions
Is Margin on the Google Play Store?
Not publicly yet. Margin is in beta on Android. Request a place below with your Google Play email and we’ll send you a link to install it from Google Play when your spot is ready.
Why do you need my Google Play email?
Google Play only lets beta testers install an app if their Play account email is on the tester list. We use it for that, and to send beta and launch emails. The app itself doesn’t ask you to sign in.
Does Margin listen all the time?
No. It only listens while you’re holding the mic button. When you let go, it stops.
Does voice logging need an internet connection?
No. Speech is processed on your phone, so it works in a basement gym or in airplane mode. It takes about three seconds after you finish speaking.
What if it hears the wrong number?
Before anything is saved, Margin shows the weight and reps it heard. Tap either one to correct it with the keypad. You can also edit any set later.
Do I still need to touch my phone?
Yes. You hold the mic button on screen while you speak. Voice saves you from typing numbers with tired hands; it isn’t a hands-free mode.
What happens after my three free voice workouts?
Everything else keeps working. You log with the steppers and keypad as before. Unlimited voice is part of Pro.
Can I keep my own routine?
Yes. Margin is built for people who already have a routine. Add your exercises and plans, and log against them. Pro’s suggestions work with your plan, not a replacement for it.
Is there an iPhone version?
It’s planned, but there’s no date yet. Leave your email below and we’ll send one message when it’s available.
What if I lose or change my phone?
Your data lives on the phone and there’s no automatic cloud backup yet. Export a CSV from time to time and import it on your new phone.
Try it at your next workout.
