Monitoring your tank is free and unmetered. The paid tiers raise the AI allowances and unlock Reef Buddy.
What is always free
- Live readings from your equipment, with dashboards and charts
- Devices, alerts and thresholds
- Journal, maintenance and livestock
- Push notifications for critical alerts
- One tank
The free allowances
| Feature | Free |
|---|---|
| Assistant messages | 20 a month. Voice draws on the same pool and costs more per turn |
| Health reports | 1 a month |
| ICP analysis | One, once: a single lifetime analysis, then locked |
| AI on tanks | Your primary tank only |
| Reef Buddy | Not included |
When an allowance runs out, everything already generated stays readable.
The trial
A 30-day Pro trial starts when you sign up, not when you first use a feature. It includes Reef Buddy and the higher allowances.
When it ends the account falls back to Free. Nothing is deleted: every reading, journal entry, report and briefing you already have stays readable.
Paid tiers
Three tiers (Plus, Pro and Max), each monthly or annual. Current prices are shown in Cora Mobile and at the store, since that is where they are charged.
| Plus | Pro | Max | |
|---|---|---|---|
| Assistant messages / month | 500 | 1,200 | 2,500 (fair use) |
| Voice sessions / month | 100 | 200 | 400 |
| Health Reports / month | 4 | 12 | 100 |
| ICP analyses / month | 1 | 3 | 30 |
| Tanks with AI monitoring | 1 | 5 | 20 |
Voice sessions are counted on their own, and every spoken reply also draws on your message allowance. Every paid tier includes Reef Buddy, ICP upload and analysis for the labs Cora reads, and comparison against your own history.
Settings → your account opens Account & Subscription.
It shows your current plan and when it renews, plus:
| Control | Does |
|---|---|
| Redeem code | Applies a promotional or partner code |
| Manage Subscription | Opens your store's subscription settings |
| Restore Purchases | Re-applies a purchase made on another device, or after reinstalling |
Seeing what you have used
Settings → Assistant & AI → Usage & Limits shows every metered feature against its monthly allowance in one place: Assistant messages, ICP analyses and health reports.
Each metered feature shows its own usage where you use it:
- Assistant: messages this month, above the message box
- Intelligence: ICP and health reports this month, under the buttons
Check these when you want to know how much of your monthly allowance is left.
Changing plan
Use Manage Subscription. Changes go through the App Store or Google Play and follow the same rules as any other subscription on your device, including that store's refund and cancellation terms.
Cancelling
Cancel through the App Store or Google Play, not in Cora. Your plan runs to the end of the period you have paid for, then drops back to Free.
If your plan is not showing
Purchases occasionally take a moment to reach Cora Mobile. If it has been a few minutes:
- Fully close and reopen Cora
- Check you are signed in to the same account that made the purchase
- Check the store account on your device is the one you bought with
If it still has not appeared, tap Restore Purchases. Failing that, email cora@coraiq.tech with the date of purchase.
