Three easy steps
Built for kitchen counters, not grow rooms.
SoakingStart a jar
Pick a crop, measure the seed, start the soak. The app already knows how long it needs to sit.
SproutingRinse on time
Twice a day for most crops. We nudge you at your own times, so nothing sits wet and forgotten.
Harvest WindowWeigh the harvest
Tip it into a bowl and weigh it. The cost, the savings and the records fill themselves in.
What you get
Everything here is something the app does today.
53 crops, already timed
Soak hours, rinses a day, days to harvest and how much seed fills your jar. Pick a crop and the whole schedule is worked out for you. Add your own crops and mixes as well.
Reminders at your rinse times
A nudge on your phone at the times you picked, in your own timezone. Not a fixed schedule somebody else decided on.

What do I need?
A jar, a mesh lid and a spoonful of seed. That is genuinely it. No soil, no grow lights, nothing fighting for windowsill space, and most crops are ready in under a week.

Questions
- Does it work on mobile?
- Yes, and that is what it was built for. Everything happens from your phone, Android and iPhone alike. Add it to your Home Screen and it behaves like any other app, rinse reminders included.
- What if I miss a rinse?
- Life happens. Skip it from the jar's rinse list. Today asks for one fewer, nothing nags you about it again, and your streak stays intact.
- Do Sprouting Trays work too?
- Yes. Pick a clay tray instead of a jar and the app comes with you: a tray gets misted rather than rinsed and drained, and every screen uses the right word for it.
- Does this app track microgreens?
- No. Sprouting Tracker is for sprouts: seeds soaked and rinsed in a jar or a tray for about a week, then eaten whole. Microgreens grow in soil or on a mat under light, which is a different job. If you want a microgreen tracking app, we make one. It is called Microgreen Tracker, and you can find it at www.microgreentracker.com.
- How do I cancel?
- Two taps in Settings. No email, no phone call, nobody trying to talk you out of it. Your jars, your history and your records stay exactly where they are.

Start here, then start a jar. Each topic links to the full guide on our blog.
What do I need to start sprouting?
A wide-mouth jar, a mesh lid, and seed sold for sprouting, never garden seed. Soak the seed, then rinse and drain it twice a day. No soil and no grow light, and most sprouts are ready in 4 to 6 days.
In the tracker: Start a jar and the app times every soak and rinse for you.
Sprouts vs microgreens: what is the difference?
Sprouts grow in water, in a jar or on a tray, and you eat the whole thing, seed, root and shoot, after 4 to 6 days. Microgreens grow in soil or on a mat under light, and you cut them above the root after a week or two.

- Can You Eat Microgreen Roots? Here's Why We Don't (opens On The Grow in a new tab)
In the tracker: Sprouting Tracker is for sprouts. For microgreens, we make Microgreen Tracker.
Microgreens vs sprouts: which is more nutritious?
Both pack a lot into a small serving, and neither wins on every count. It depends on the crop and on what you are after. Sprouts are ready sooner and need only a jar. Microgreens take longer and need light, and give you more leaf.
In the tracker: Weigh each harvest and see what your own jars really yield.
How do I grow broccoli sprouts?
Soak 2 tablespoons of broccoli seed in a quart jar for 4 to 8 hours. Drain it, then rinse and drain twice a day. Broccoli sprouts are ready in 4 to 6 days, once the small leaves open.
In the tracker: Broccoli is built in, with its soak, its rinses and its harvest window.
Micro broccoli vs broccoli sprouts: which should I grow?
Same seed, two crops. Broccoli sprouts grow in a jar and you eat them whole in 4 to 6 days. Micro broccoli, or broccoli microgreens, grows in soil or on a mat under light, and you cut it above the root after about 8 days.

Which sprouts should I grow first?
Alfalfa and broccoli are forgiving and ready in under a week. A salad mix gives you a little of everything from one jar.
