Every batch, recorded.
You weigh the trays in and out. LyoLog works out the yield, the grade and the cost per kilo, and keeps every run one search away. 49 machines are already set up, from five makers, and anything else takes a moment to add by hand.

Free covers one machine and eight batches a month. Past that, Pro is €2.99 a month or €29 a year. Nothing is locked either way.
Five steps from an empty tray to a closed record.
Everything happens on the phone you already carry, in the drying room, with cold hands and short attention.
Pick the recipe and the machine.
Choose what you are drying and which machine it goes into. LyoLog loads that machine's stages and the recipe's temperatures, so the plan is on screen before the first tray goes in.
Running a machine that is not in the list? Set it up by hand once and it behaves like every other machine.
Trays in, gloves on.
Weigh each tray as it goes in. Tray tares are calibrated once, so you type the gross weight and LyoLog takes the tare. The batch is running in three taps.
Weigh each tray empty once. After that you put the loaded tray on the scale and type what the scale says. LyoLog takes the tare off. Nobody should be doing subtraction at six in the morning.
You are not in the drying room.
Two machines, two batches, one screen. Each shows the stage it is in and when it will finish. When a cycle ends your phone tells you, instead of an alarm going off in an empty building.
A finished batch sitting in a warm chamber starts taking moisture back. If nobody records the unload, LyoLog asks again the next day, and again a week later.
Dry enough to unload? Ask the scale.
When the cycle ends, weigh a control tray. If it is still losing weight, add another drying round and weigh again. Every round is kept, so you can see where the weight settled.
Two weigh-ins that agree within a couple of grams tell you more than any timer.
Weigh, grade, close.
Dry weights go in tray by tray, and the yield, the water removed and the duration come out of them. Each tray takes its grade, its colour and structure, and its moisture and water activity reading. Log the batch before the trays are washed.
Forgot to start the timer? Log the batch afterwards. A run written down late is worth more than a run never written down at all.
Questions a clipboard cannot answer.
Paper records what you remembered to write. LyoLog records the batch.
Which tray was which?
Trays of the same type still weigh differently. Each one gets a label and its own calibrated tare.
How much water did we remove this month?
Every closed batch adds to the month, broken down by product and by machine, kilograms in against kilograms out.
Was that our recipe or the manufacturer's?
Every recipe carries its source and version. Manufacturer recipes are read-only; clone one and it becomes yours. Edit a recipe and it becomes a new version, while each batch keeps the version it ran. The Runs section shows what the recipe actually did: number of runs, average cycle, average weight loss and the load range.
What did we change last time?
Notes and grades stay attached to the batch and the recipe. The next run starts from what you learned.
The question the machine cannot answer.
A cycle ending is a timer running out. Whether the batch is dry is a different question, and the scale is what answers it.
Weigh a control tray, put it back, run another round, weigh it again. When the weight stops moving, the batch is dry. Every round is kept, so the next time you run this product you can see where the weight settled instead of remembering it wrong.
Calculated from what you weighed. Not typed in, so not wrong.
Add another round and the first one stays. Next time you run this product you can see where the weight stopped moving, instead of remembering it wrong.
Works where the machines are.
Cold rooms and metal buildings are where phone signal goes to die.
Start a batch, log tray weights, advance the stages and take photos with no signal at all. Everything is saved on the phone and goes up on its own once you are back in range. You need a connection to sign in the first time, and to load your records onto a new phone.
One machine in the garage or six on a line.
One Harvest Right, a notebook full of guesses.
Know which slice thickness worked and stop re-running the failed recipe.
Two or three machines and a label to justify.
Yield per kilogram, batch numbers on every jar, and a record to show the buyer who asks.
A team, shifts, and an inspector twice a year.
Who started what, when, and on which machine. A record you can hand over.
Four ways to keep a batch record
Most freeze-drying gets written down on paper, if it gets written down at all. Here is what each way actually does for you.
| Notebook | Spreadsheet | The machine's own screen | LyoLog | |
|---|---|---|---|---|
| Survives a cold room and wet gloves | Sometimes | It's on a laptop somewhere | Yes | Yes |
| Still readable in two years | If you kept it | If you kept the file | Gone at the next run | Yes |
| Finds last spring's strawberry run in two taps | No | If you built it that way | No | Yes |
| Works out yield and weight loss for you | No | If you wrote the formula | No | Yes |
| Tells you the batch is dry | No | No | It tells you the cycle ended | Yes, from your own weigh-ins |
| Keeps grade, moisture and water activity per tray | If you drew the columns | If you built it | No | Yes |
| Chases you when a finished batch sits unloaded | No | No | An alarm in an empty building | On your phone, and again the next day |
| Gives you a cost per kilo | No | If you built it | No | Yes, on Pro |
| Shows what each machine and product produced this month or this year | No | If you built it | No | Yes, on Pro |
| Passes a recipe on to another operator | A photocopy | Email the file | No | A link or a PDF card; they get their own copy |

A spreadsheet can do most of the middle rows. It takes an evening to build, it doesn't come into the drying room with you, and it can't tell you the batch is dry.
Built around the batch, not the spreadsheet.
Every machine on one dashboard
Running batches stack as rows, so two or three are on screen without scrolling. Idle machines shrink to one line with a + to start the next batch.
A recipe library with provenance
Manufacturer recipes, ours, the community's and your own. Each one carries its stages, temperatures and pressures, and says which machines and which firmware it fits. Share one as a link or as a one-page PDF card: whoever opens it gets an editable copy of their own.
Any freeze dryer
Pick your model from the list. If yours is not in it yet, set the machine up by hand and log it exactly the same way.
A record that holds its shape
One page per batch: what went in, the stages it ran, every tray weighed, the yield, the grades and the notes. It reads the same in two years as it does tonight.
Three languages
English, Spanish and Portuguese. The app, the record and the help pages.
Cold hands. Bright room. Dark room.
Buttons are big enough to hit with gloves on, the numbers stay readable at arm's length, and the app follows whatever your phone is already set to. Try it.
Every freeze dryer. Including yours.
49 models are already set up, from Harvest Right, Leosmak, Lyotrade, Blue Alpine, Stay Fresh and Exeat. Pick yours and LyoLog loads that machine’s own stages, its shelf and tray layout, and the recipes that fit it.
Running something else, or something you built? Set it up by hand in a minute and log it exactly the same way. Nothing about the record changes.
All 49 machines, one page each →
LyoLog is a production logbook. It is not a validated system and it is not intended for GMP records.
Your records, in Europe, and yours to take
Everything is stored in the EU. Export the lot as a file whenever you want, on any plan, including the free one. Delete your account from inside the app and it is deleted on the server, not queued for someone to action. Metrics export as a CSV file too.
Location is a country and a city you type in. No coordinates, no tracking, nothing sold to anyone.
Free for one machine.
Records are never locked behind a plan. Pro adds the rest of the room.
- One machine
- Eight batches a month
- Metrics for the last 30 days and by month
- Recipes shared as a link or a PDF card
- Your records, exportable as a file
- Three languages
- Every machine you own
- Batches without a monthly limit
- Cost per kilo: energy, labour, packaging and machine wear
- Metrics over 12 months, by machine, product and recipe
- Everything in Free
- LyoLog on the web, at lyolog.app/app
At the monthly limit LyoLog stops taking new batches. It does not lock the old ones and export stays free. Your records were never ours to hold.
Before you ask.
Does LyoLog connect to the freeze dryer?
LyoLog doesn't need a connection to your freeze dryer, so it works with all of them, including machines with a dial and no display.
What if my machine is not in the list?
Add it in manual mode: name, tray count, tray type. The record is identical. Tell us the model and we add it to the library.
Does it work without a signal?
Yes. Start a batch, log weights, advance the stages and take photos with no connection; it all saves on the phone and syncs by itself once you are back in range. Signing in the first time and moving your records to a new phone are the two things that need a connection.
How do I share a recipe?
Open the recipe and tap Share, then send it as a link or as a one-page PDF card with the stages, the settings and a QR code. Whoever opens it saves an editable copy to their own recipes. Your batches, notes and costs are never part of it. A link can't be withdrawn from the app yet, so share it only with people you would give the recipe to anyway.
Where is my data stored?
In the EU. Records stay for as long as the account exists, on Free and Pro alike, and you can export the lot as a file at any time.
Can I use LyoLog on a computer?
Yes. Pro accounts open lyolog.app/app in any current browser: the same account, the same records and the same screens as on the phone. Free accounts can sign in there to export their data.
What goes into the cost per kilo?
What you enter: material, labour, packaging and other costs, plus energy and, once you add the machine's price, machine wear. Energy uses your electricity rate. Until you set one, LyoLog uses the national average for business customers in your country, excluding VAT.
Which languages?
English, Spanish and Portuguese. The app, the batch record and these help pages.
Start the next batch with a record already open.
