Runoff test log for iPhone

Map your room. Log every pot.

Build your grow room in 3D in about a minute: tables, plants per table, rows. Then each test is a tap on the pot and a number on the pad. Every pot shows how its runoff compares to what you fed.

Make it yours

Five table looks. Four report styles.

Pick the bench your pots sit on and the report your client sees. Everything else stays exactly as simple.

Open table

Your table, your look.

Open any table full screen and work pot by pot. Choose the surface in Settings; every reading keeps its colour on every look.

Share as PDF

A report that looks pro.

Share any test as a PDF in one tap. Four styles, from a drawn room scan to a one-page text card.

How it works

Set it up once. Then it's habit.

A full test is a few taps per pot, and the report writes itself.

MAP

Build the room in 3D.

Set the number of tables, plants per table and rows. Runoff Radar draws the room with every pot in place, and keeps a cover photo for each room.

  • As many rooms as you grow in
  • Tables, plants per table and rows
  • PPM 500, PPM 700 or EC

LOG

Tap a pot, type the number.

Write down what you're feeding, then work along the bench. One big number pad, one Enter key. pH-only tests when that's all you checked, and a flush still records the water's pH.

COMPARE

See what changed since last time.

Pick any earlier test and see it side by side, table by table, with each pot's change up or down.

ROOMS

Every grow room, one tap away.

Each room keeps a dated log of its tests with your notes, like "Flushed table 2 after this", so you can look back at any week.

SHARE

Send the report.

Text it, email it or keep it with your records. Room averages, change since last test, every table and every pot.

Seedlings under grow lights

Wherever you grow

Built for the bench, not the desk.

Runoff Radar works with any PPM, EC or pH pen you already own. You read the meter and type the number; it keeps every pot in order, offline.

Questions

Good to know.

Does it connect to my meter?

No. Use any PPM, EC or pH pen you like and type the reading. That keeps it simple and works with every brand.

What is a runoff test?

You water a pot, catch the water that drains out the bottom and measure its PPM or EC and pH. Compared with what you fed, it shows whether salts are building up in the pot or the plant is running lean.

Do I need internet or an account?

Neither. Runoff Radar works fully offline and has no sign-in. Your data stays on your iPhone and in your normal iPhone backup.

What happens after the 7 days?

You can unlock it once to keep making new tests and rooms. If you don't, everything you've logged stays yours to open and share.

Is there an Android or iPad version?
