Fair trade-offs
Paper never needs updates, logins, or battery. Sensio needs a phone but rewards you with searchability and statistics your hand cannot match on week three.
Where each approach wins
Notebooks shine in simplicity and zero vendor dependence. Sensio shines when delay, mixed meals, and forgotten side dishes would otherwise blur your memory.

Our verdict
If you love journaling and will keep it up, paper is valid. If you have tried and abandoned notebooks, that is not a moral failure — switch to a workflow you can sustain. Sensio exists for that gap.
Frequently asked questions
Is a paper food diary still effective?
Yes when maintained with enough detail and date-stamped symptoms.
What if I prefer not using apps?
Use paper, or hybrid: paper meals + phone photos for backup.
Can I use both together?
Yes — some people photograph for AI parsing and jot feelings in a notebook.
How long do I need to track?
Aim for at least 2–4 weeks of consistent entries before judging.
