Draft of 10 November 2026.
The app calculates your cats' energy and nutrient requirements and compares them with what they eat. It does not replace veterinary advice.
Write to support@lab1337.ch. Please include the app version (More → Info → About) and, if possible, the steps that lead to the problem. Do not send backup files unless asked: they contain all your data.
Why does the balance show "unknown" or "at least x %"?
Labels often omit nutrients or state only added amounts. A missing value never counts as 0. Every balance explains this behind ℹ︎.
Why does the app assess only the energy?
Micronutrients need a requirement profile. Add your own under More → Requirement profiles, for example with values from your vet, and choose it for the cat.
Why does the app not calculate for my kitten?
For kittens under 40 weeks and for pregnant and lactating cats, the app calculates only with an own profile that states the energy.
How do I back up my data?
Under More → Backup you create a file with all data and save it to Files, iCloud Drive or a computer. On a new device you restore it there.
The app no longer opens my data.
Do not delete the app. It then offers "Save raw data". Save the file and contact support.
