What Runoff Radar does
Runoff Radar is a simple log for runoff tests. Build your grow room once, with its tables and pots. Then, for each test, tap the pots you checked on a map of your tables and type in the runoff PPM or EC and the pH.
Each room keeps a dated journal of its tests. Every pot shows a colour that tells you how its runoff compares to your feed:
- Green on target
- Amber building up
- Red high
- Blue lean
It works fully offline, with no account, and your data stays on your iPhone.
Common questions
How do I start the free trial?
Open a room and tap + Entry. The first time, Runoff Radar offers a free 7-day trial of everything. Tap Start free trial and Apple shows its own sheet with the price Free. Confirm it and everything is open for 7 days. Your first room is always free to make.
What happens after 7 days?
All your rooms and tests stay yours. You can still open them, edit them and share them as PDFs. Making new tests and new rooms needs the Runoff Radar unlock, a one-time purchase. It’s not a subscription and nothing renews. The price is shown in the app before you buy, and you can buy it any time from Settings → Runoff Radar unlock.
How do I restore my purchase?
Open Settings (the round button at the top right of Your rooms) and tap Restore purchases. It’s also on the unlock screen. Make sure you’re signed in with the same Apple Account you bought with.
Where is my data? Is it backed up?
On your iPhone, inside Runoff Radar. There’s no account and nothing is stored on our servers. Your rooms, tests and photos are part of your normal iPhone backup (iCloud Backup or a backup to your computer). If you set up a new iPhone from that backup, Runoff Radar’s data comes with it.
How do I switch between PPM and EC?
Open Settings and find “What does your meter show?”. Pick EC, PPM (500 scale) or PPM (700 scale). Your older tests switch to the new unit too, so nothing needs to be typed again. If you’re not sure which PPM scale your meter uses, check its manual or label.
How do I share a test as a PDF?
Open a test and tap the share button at the top. Pick one of the four styles (Room scan, Lab report, Journal page or Text card) and tap Share PDF. You can send it by Mail or Messages, or save it to Files. To print your name or business at the top, fill them in under Settings → Reports.
How do I compare with an earlier test?
Open a test and tap Compare. Pick an earlier test and each pot shows how much it went up ▲ or down ▼ since then.
Does it work without internet?
Yes. Everything works offline, in the grow room or anywhere else. Only purchases and restoring them need a connection.
