Why Peak Dough exists
Fermentation is the part nobody can see.
Your starter rises, peaks and falls on its own schedule. A warm kitchen speeds it up, a cold one slows it down, and from the outside it all looks the same. So you check the jar, you mark it with a rubber band, and you guess.
Feed it too late and it has already fallen. Bake with it too early and the loaf comes out dense. Most failed loaves are not about technique. They are about timing.
- No way to tell whether your starter has peaked or is still rising.
- No record of how fast it rose last time, so every feed starts from zero.
- No alert when it is ready, so you keep checking.
Peak Dough
Stop guessing. Know when it's ready.
A rubber band on the glass tells you where your starter was. Peak Dough tells you where it is now, and when it will peak.
A regular jar
- ✕ A rubber band on the glass
- ✕ Checking it every hour
- ✕ Guessing when it peaked
Peak Dough
- ✓ Measures the rise for you
- ✓ Tells you when it peaks
- ✓ Feed and bake on time
What it does
A lid that watches your starter for you.
Measures the rise
A distance sensor in the lid tracks how high your starter climbs.
Talks to the app
Every reading goes straight to your phone.
Knows when it peaks
You get an alert, so you feed and bake on time.
Dishwasher safe
Thick glass jar. The sealed lid rinses clean under the tap.
The Peak Dough app
Your starter, in your pocket.
- ✓A live curve of the rise. See exactly where your starter is, from anywhere.
- ✓An alert the moment it peaks. No more checking the jar every hour.
- ✓Time left until the peak. Plan your mix around your day.
- ✓A log of every feed and rise. Learn how your starter behaves.
- ✓Free, no subscription. iOS and Android.
App screens are illustrative.
How it works
01
Connect to Wi-Fi
Plug in the small Wi-Fi hub from the box and connect it in the app. The lid pairs on its own.
02
Feed and close the jar
Feed your starter as usual and put the sensor lid on. It wakes every few seconds to take a reading.
03
Watch the rise
The app shows the rise curve from anywhere. Go about your day.
04
Bake at the peak
You get a notification when your starter peaks. Mix your dough while it is at its strongest.
The lid charges wirelessly on the included charger, and its software can be updated over the air.
Add-on: Smart Heater
A cold kitchen, handled.
In a cold kitchen a starter can take hours longer to rise. The Smart Heater is a warming plate your starter jar stands on. You set the temperature in the app and the heater keeps the jar there, so your starter rises on your schedule, not the weather's.
Optional. The sensor lid and app work without it.

Frequently asked questions
When will it arrive?
Estimated delivery is March 2027. Peak Dough was funded on Kickstarter in April 2026, and the lid, hub and heater now work together end to end on their production boards. What is left is calibration, battery testing, sourcing the material for the lid's sensor window, and then tooling and production. This page is always updated with the latest timeline.
Starter Jar or Starter + Proofing Bowl?
The Starter Jar is everything you need to track your starter: the sensor lid, the jar, the hub, the charger and the app. Choose Starter + Proofing Bowl if you also want to follow your dough: it adds a glass bowl with its own lid, and you move the sensor from the jar to the bowl.
Can I track the jar and the bowl at the same time?
Each kit comes with one sensor lid, which you move between the jar and the bowl. It tracks one of them at a time.
Do I need the Smart Heater?
No. The sensor lid and app work on their own. The heater is for cold kitchens: your starter jar stands on it and it holds the temperature you set in the app.
Does the app need a subscription?
No. The Peak Dough app is free on iOS and Android, with no subscription and no monthly fee.
Can I cancel my pre-order?
Yes. You can cancel for a full refund any time before your order ships. Just email hello@better-objects.com. Once it has shipped, pre-orders can't be returned for a change of mind, except where the law gives you that right: customers in the EU, EEA and UK can withdraw within 14 days of receiving their order. Faulty or wrong items are always replaced or refunded.
I backed Peak Dough on Kickstarter. Do I need to order here?
No. Your Kickstarter pledge already covers your reward. This page is for everyone who missed the campaign.
