OpenA FEW GOOD QUESTIONS
Before the next season.
Is the app free?
Yes. The diary, the calculations, pre-harvest intervals, stock, the cellar register and PDF export are free. Only an optional AI feature may be paid, once it exists.
Does it help with electronic pesticide records from 2027?
Kletio keeps your spray records electronically, as you go and without a signal, and exports them as a PDF. Whether the export matches the official electronic form is still being checked — see the guide to electronic pesticide records.
Does it work without an internet connection?
Yes. The vineyard and cellar diary works on your phone without a signal. An internet connection is needed for online features such as optional cloud sync and connected iSpindel readings.
Do I need to create an account?
No. You can keep your diary entirely on your phone. An account is optional and enables cloud features; cloud sync is a separate choice.
Is it available for my phone?
The app currently supports Android. Visit the download page for installation guidance. There is no iPhone version in the current release.
Can I take my records with me?
You can export spray diaries and cellar registers as PDFs, and create a full JSON backup. Export before uninstalling the app, because uninstalling removes its local data.
