Sennight · A Tessel Labs app
Your whole week, adapted to how hard you train.
Log your training, food and weight. Once a week, Sennight reviews what happened and plans the next week: your targets, your meals, your shopping list and a suggested training change, each with its reason. Coming to Android in 2027.
How it works
One check-in a week. Your whole week, planned.
Log
Your training, food and weight. Scan a barcode, search, or pick a recent food.
Check in
Once a week, see how last week went: intake, weight trend and how hard you trained.
Review the plan
Next week’s targets, meals, shopping list and training suggestion, each with its reason.
Confirm
One tap and the week is set. Nothing changes without your say-so.
A heavy week changes everything downstream.
Other apps track one thing. Sennight connects them, so how hard you train flows through the rest of your week.

Built on a few promises
Show the working
Every change comes with its reason. Estimates are labelled as estimates.
Suggest, never impose
Nothing changes until you confirm.
Your normal, not ours
“Heavy” means heavy for you. Sennight learns your normal over your first four weeks.
Calm, not pushy
No guilt, no streak-shaming. A missed day is just data.
Works wherever you are
Built on a worldwide open food database, with your units and your local date and number formats.
Private by design
Your data is never sold or used for ads. Export or delete it any time.
