A calm, private journal for bloating. Log how you feel and what you eat, take one photo a day, and see your own patterns over time.
Download for iPhoneOur story
One day you feel fine; the next, your jeans are tight and you can't say why. Everyone has a theory. We built Tumlo to be the opposite of noise: a calm place to write down how you feel, what you ate and how you slept, and to look back at your own record without anyone telling you what it means.
No account. No ads. Your journal stays on your iPhone.
How it works
Comfort, water, sleep and stress, in under a minute.
Type what you ate, or scan a barcode or an ingredients list to see which of your tracked ingredients it contains.
Same light, same time. Each photo sits next to your own baseline, side by side.
A gentle Comfort Score and a timeline of your days, compared only with yourself.
Private by design
Entries and photos live in Tumlo's private storage, excluded from iCloud backup. Export everything whenever you like.
No sign-up and no login. We run no server that receives your journal, so we never see it.
Online barcode lookup is optional. When it's on, only the barcode or search text goes to Open Food Facts.
No. Tumlo is a general wellbeing journal. It isn't a medical device and nothing in it is medical advice. If you have persistent or severe discomfort, please see a doctor. Your Tumlo export can help you describe what you've noticed.
Only on your iPhone, in Tumlo's private storage, excluded from iCloud backup. There is no account and no server that receives your journal. You can export everything at any time. Read the privacy policy.
No, on purpose. Tumlo is about how you feel, not numbers on a plate.
Tumlo is free to download. The journal features need Tumlo Pro, an auto-renewing monthly or yearly subscription. You always see the price in the app before you buy.
On your iPhone, open Settings → your name → Subscriptions → Tumlo. Cancelling stops the next renewal, and you keep access until the period ends. Refunds are handled by Apple at reportaproblem.apple.com.
In Tumlo, open Settings → Delete all my data. It removes every entry and photo. Deleting the app removes everything too.
