From germination to harvest: climate readings, costs and feeding in one place — completely offline on your Android device. No cloud, no sign-up.
No scattered notes, no paper chaos. CRIS brings your journal, costs and feeding together in one app.
And not just this page: the app itself is fully translated — menus, help texts and calculators included.
Climate readings, watering, feeding and photos — captured day by day, neatly sorted by week and phase.
Equipment, nutrients, soil and electricity are added up automatically — per grow and per gram. You always know what your grow really costs.
Set up schedules per week and phase, and scale the amounts to your water volume automatically — no more scribbled notes.
Trends for height, climate, pH and EC as charts — spot patterns and learn from grow to grow.
CRIS stores everything exclusively on your device. No account, no cloud, no tracking — no one but you sees your grow.
Every entry lives offline on your device. No server, no transfer.
No account, no email, no sign-up. Open the app and get going.
No ads, no analytics services, no sharing with third parties.
The legal situation for private home growing differs from country to country and keeps changing. CRIS is purely a documentation tool and not legal advice — please check the rules that apply in your country.
