Track livestock growth, water parameters, expenses and your tank's
full story — with analytics that spot problems before you do.
Cloud-synced from day one, even on the free plan.
Parameter, journal and expense quick-adds are always one tap away,
on every screen. Open the create button on an entity page —
Aquariums, Livestock — and that page's own create action
automatically stacks on top.
1
Context-aware creation
The quick-adds never move; the page you're on simply adds its
own action to the top of the stack.
2
Flows that guide you
Illustrated empty states, step-by-step wizards and smart
defaults walk you from first tank to full reef.
3
Instant feedback
Add a record and the dashboard refreshes immediately — no
stale screens, no pull-to-refresh ritual.
Try it — tap a tab, then the + button
On Home, the quick-adds:
The same create button, exactly as it behaves in the app.
Everything, tracked
The full life of your tank, beautifully organized
Four pillars of aquarium keeping — each with its own home, its own
color, and charts that make sense of it all.
Livestock growth tracking
Log growth entries over time for every fish, coral and invert —
with progress photos on Premium.
Parameter and expense charts start as scrollable cards right in
your lists. Tap expand and the chart rotates into a full-screen
landscape workspace — with filters at your side and real
statistics on your readings.

Anomaly detection
Readings that deviate more than 2 standard deviations from
your trend line get flagged instantly — catch a nitrate
spike before your fish do.
Next-period forecast
A moving-average projection shows where each parameter is
headed — and by how many percent it will move.
Trend lines
Least-squares regression over your history tells you whether
things are drifting — long before it's visible to the eye.
Filters at your side
In landscape, a drawer slides in beside the chart — refine
by date range, tags or type without ever leaving the view.

AquaElectron is a record-keeping and analysis tool. Trend lines,
anomaly flags and forecasts are calculated from the readings you
enter and are provided for information only — they are not
veterinary, animal-health or professional advice, and they are not a
substitute for your own judgement or a qualified professional's.
Always confirm readings with a test kit before acting on them.

Species database
1000+ species, one search away
Adding livestock starts with a ranked, instant search over a
database of more than a thousand fish, corals, inverts and plants —
scientific names included. Start typing, tap, done. No more "orange
fish #3".
✓
Ranked instant search
Results ordered by relevance as you type, narrowed by
livestock type.

Freshwater to full reef
Fish, corals, invertebrates, plants and more across every kind
of setup.

Billing & cancellation. Premium is an
auto-renewing subscription sold through Google Play (Android) or
the Apple App Store (iPhone and iPad) on a monthly or yearly
plan. Current prices, and any free trial or introductory offer,
are shown in your local currency in the app and in the store at
the point of purchase; local taxes may be added by the store at
checkout.
Your Google Play or Apple ID account is charged at confirmation
of purchase and again at the start of each renewal period, unless
you cancel at least 24 hours before the current period ends. You
can cancel at any time in your
Google Play subscription settings
or, on iPhone and iPad, in
Settings → your name → Subscriptions. Cancellation stops future charges; it does not refund the
period already paid for. Refunds are handled by the store you
bought from, under
Google Play's refund policy
or
Apple's refund process. A Premium subscription applies to the platform it was bought
on — Google Play for Android, the App Store for iPhone and iPad —
and is managed through that store. There is no separate charge
from LeptonO Inc. and no payment details are collected by us.
Full details are in our Terms of Use.

cloud sync included. Premium unlocks unlimited aquariums, photo
features, custom tags and data export (see the comparison above).
Will I lose my data if I switch phones or reinstall?

How do I cancel my Premium subscription?
Subscriptions are billed and managed by the store you bought from
— Google Play or the Apple App Store — not by us. On Android,
cancel in your Google Play subscription settings; on iPhone or
iPad, open Settings, tap your name, then
Subscriptions. Cancellation stops future renewals but does
not refund the current period; refunds are handled under Google
Play's refund policy or Apple's refund process.
How do I delete my account or my data?
You can permanently delete your account and all data from inside
the app: open Profile, scroll down, tap
Delete Account, confirm the warning and type the
