why another app?
most grow journals were not built by growers.
they ask for an account, or push the cloud, or show ads. we did the opposite: everything local, the way a grower actually needs it.
no sign-up wall
open the app, you are in. no account just to log the first watering.
no forced cloud
your data stays on your phone. sync between devices only if you flip on premium.
no ads
a paid app at the cheapest store tier. nobody selling your data, nobody pushing banners.
more than photos
pH, EC, TDS, temperature, RH, feedings, prunes, transplants. all in the feed, all on the charts.
features
everything a grow journal needs.
built by growers, for growers.
crops and plants
organize by room, tent or garden bed. each plant has genetics, stage, its own timeline.
instagram-style feed
every event — water, prune, transplant — lands as a card on the home feed with photo and context.
environment charts
pH, EC, TDS, temperature, humidity. compare variables and see how environment shapes the cycle.
private photos
capture with the camera or import from gallery. images stay in the app sandbox — no external gallery sees them.
local reminders
recurring tasks (water, prune, feed) become push notifications on the phone, with no server in the middle.
sprays and ferts library
add once, reuse across every crop. quantities per plant with decimals.
export reports
generate a backup of the full crop with events, photos and charts — archive or share.
multi-light and outdoor
combine LED + HPS in the same crop, or mark it outdoor and follow the natural cycle.
lunar calendar
moon phases and planting windows right on screen — for the biodynamic crowd.
your photos never touch the phone's gallery.
in-app camera + import, protected sandbox, zero uploads. grow photos and videos stay invisible to the system gallery — even if someone picks up the unlocked device.
- invisible to the system gallery
- iOS / Android internal encryption
- nothing leaves the device — 100% local
why GrowerHelper
what most grow journals just don't do.
a side-by-side of where GrowerHelper stands apart from the rest of the market.
truly 100% offline
open, log, chart and export a backup with zero internet. most competitors gate the first open behind a login — you become hostage to a network.
zero account, zero email
on first open the app spins up an anonymous local identifier. we never ask for name, email or phone. your data is not tied to an "account" — it's on your phone.
bluetooth sensors built in
read temperature, humidity and soil straight from Mi Flora, RuuviTag and the rest via BLE. no vendor app, no vendor cloud in between.
no trackers at all
zero trackers, zero pixels, zero heatmaps. we literally cannot tell what screen you opened.
4 languages, hand-written
pt-BR, en, es and nl — every locale written by the team, not run through an auto-translator.
photos only you can see
grow photos and videos live inside the app, protected by the phone's own encryption. the system gallery never sees them.
how you use it
everything on the phone. cloud when you want.
the app is complete on its own. premium is optional, and only makes sense if you want to sync between devices.
