FAQ
Questions growers ask us
If it’s not here, we’re a message away on Discord.
Does the app work without internet?
Yes — the app is local-first. VPD chart, diary, calculators and guides work fully offline. Only smart-device automation needs internet (because your gear’s cloud requires it).
How much does it cost?
Free tier is fully usable. Pro is $3.99/month, $24.99/year (save 48%), or $49.99 lifetime — pay once, keep forever.
Will I lose my data?
No. Your diary, photos and settings live on your device — not our server. Optional LAN sync between phones, full PDF/JSON export anytime.
Is there a beta?
Yes — jump on our Discord for early TestFlight / APK access and to help shape what ships first.
Can I migrate from Grow with Jane or Photone?
Diary import is on the roadmap. In the meantime, you can keep your old app running while you set up here — nothing breaks.
