Stag & rhino beetle records, plus a Raise & Battle Game
Every joy, remembered for life!
From each beetle’s records to labels, bloodlines and connecting with other breeders.
KKLOG is a keeping and breeding record app for stag and rhino beetle breeders. It supports your keeping every day, with everything from a log for each beetle and its larval growth chart to beetle labels with QR codes, printed in a layout of your own, food change alerts and a schedule calendar, breeding memos, and “Community beetles”, where you connect with other breeders. There’s also the Raise & Battle Game, where you raise beetles from eggs. You can play it on Apple Watch, too.

Log each beetle, watch it grow
Add a beetle with its beetle ID and species, then just keep logging. Log a food change, pupation or eclosion, and the beetle’s stage, hatching date and eclosion date all update automatically.
- Easy registration
Pick species, sex, generation and more from lists. Choose a stage when you add a beetle and its first log is created automatically. You can also start its records from a wild collection or a purchase.
- Logs
Record weight, head width, container, food and notes by date. Pick a log type such as condition check, food change, hatching, pupation, eclosion, first feeding or harvest.
- Larva growth chart
Logged larva weights are charted against days since hatching. See at a glance where the weight shot up.
- Photos
Keep photos of each beetle: how it grew, and how it looked when it eclosed, all with its records.
- Locality, bloodline and generation
Locality, bloodline, parent ♂ and parent ♀, and generation (WD, F1, CBF1 and more) for every beetle. Choose parents from the adults you’ve added and trace the bloodline back.
- Saved to the cloud
Your records are saved to the cloud. When you change phones, log in with the same account and carry on where you left off.

Print case labels in a layout of your own
Make labels for your breeding cases from your beetles’ info. Drag the items you want, such as species, scientific name, generation, eclosion date and a QR code, to wherever you like, and print straight onto A4 label sheets. Scan the QR code on a case and that beetle’s page opens right away.
- Choose beetlesChoose the beetles to print and set how many labels each one gets. From “…” on a beetle’s screen, print just that one right away.
- Choose or make a layoutEach sheet type comes with three layouts. With “Edit layout”, drag items to move them and resize them by their corners.
- Print on A4 sheetsCheck the result in the preview, then print. You can also share it as a PDF.
- From QR code to beetleScan a label’s QR code with your phone’s camera, or with the QR button in the My beetles search field, and that beetle’s page opens.

For a partly used sheet, tap its first empty label to start printing there. If the print doesn’t line up with the sheet, you can adjust the position for each device.
- Put each item where you want it
Species, scientific name, sex, generation, locality, length, weight, beetle ID, eclosion date, bloodline, breeder and QR code, plus free text. Choose the text size, weight and alignment, and items snap to a 1 mm grid and to the edges of other items as you move and resize them.
- One scan to the beetle’s page
Scan the QR code in front of the case to check logs and photos on the spot. Your own beetles open as usual, and beetles you haven’t made public aren’t shown to anyone else.
- Print directly, or as a PDF
Print on your own printer with the iPhone or Android print feature. When printing, set the paper to A4 and the scale to 100%.
- Label printing is free for everyone
- Three ready-made layouts, plus editing
- QR codes and scanning
You can save one layout of your own for free. With KKLOG Plus, you can save as many as you like.
Find the beetle you need, right away
Even as your collection grows, search by beetle ID, filter and sort to list just the beetles you want to see. To split them up by shelf or room, use Groups.
- Search by beetle ID
Type a beetle ID into the My beetles search field to find it right away. The QR button in the search field scans a beetle label’s QR code to open that beetle.
- Filter
Filter by species, stage, sex or listing. You can also choose “Only beetles with a food change due soon or now”, and whether to include deceased and transferred beetles.
- Sort
Sort them the way you want: “Food change due (soonest first)”, “Larva weight (heaviest first)”, “Adult length (largest first)”, “Eclosion date (newest first)” and more.
- Groups
Organize your beetles into groups that match where you actually keep them, like a breeding room, a shelf or a greenhouse.

GroupsBy shelf or room
Never miss a food change or harvest
Set a food change interval for each species, and beetles nearing their due date show “Food change in X days”, while beetles past it show “Food change needed”. The Schedule calendar shows your food changes and harvests month by month.
- Food change alerts
Set the days until a food change for each of L1, L2 and L3. When you add a beetle, its species gets an interval automatically, which you can change in “Food change alert settings”.
- Schedule calendar
Food change due dates and target harvest dates on a monthly calendar. Tap an entry to open that beetle or breeding memo.
- Notifications
Notifications arrive in the iPhone and Android apps at the time you set (once a day at most). Choose “Start reminders” and “Notification time” in “Reminder settings”.

Bloodlines and offspring, all in a breeding memo
Make a breeding memo for each pair (or mated female) and keep everything from the laying set and harvest to registering the next generation in one place. Enter the laying set date and the days until harvest, and you’ll get a reminder as the harvest approaches.
- Harvest log
Record how many eggs and larvae you harvested on the day. You can also note whether you continued the laying set with the same female or ended it.
- Register offspring
Register harvested eggs and larvae as beetles all at once, just by entering how many. They inherit the parents’ info, and beetle IDs are assigned automatically as “prefix-harvest date-number”.
- Offspring bloodline and generation
Set the next generation’s bloodline name, generation and description in the memo ahead of time.

Connect with fellow breeders
Beetles you make public appear in “Community beetles”. See how other breeders’ beetles are growing and where their bloodlines come from, and follow the breeders who catch your eye to check on them all in “Following”.
- Likes
Like the beetles you love. You’ll get a notification when one of your beetles gets a like or someone follows you.
- Profile
The beetles you keep are counted by species and shown in charts for adults and larvae. Your public beetles and your Raise & Battle Game card are on the same page, and you can share it with a link.
- Follow
Follow the breeders who catch your eye, and visit their profiles anytime from your “Following” and “Followers” lists.
- My QR
When you meet breeders at an event or elsewhere, show each other your QR codes with “Add friend” and follow on the spot.

Frequently asked questions
Is it free?
Yes. Downloading the app, keeping records, printing labels and the Raise & Battle Game are all free. On the free plan, the app shows ads. There’s a limit on how many beetles you can register, which you can raise with “Add beetle slots” in the menu. KKLOG Plus has no limit.
What paper should I use for beetle labels?
You can print on A4 label sheets (12 or 24 labels). To be safe, do a test print on plain paper first with “Print outlines” turned on, and lay it over a label sheet to check the position. If it’s off, fix it with “Print position”.
Where are my records saved? What if I change phones?
Your records are saved to the cloud. On a new phone, log in with the same account (email, Google or Apple) and pick up right where you left off. You can also see the same records in the web version.
Are there differences between iPhone, Android and the web version?
- Widgets and Apple Watch are for iPhone and iPad only.
- The web version doesn’t have photo uploads, notifications, the Stag & rhino beetle map or KKLOG Plus sign-up. Everything else, from records to the Raise & Battle Game, works in the web version too.
How do I change the language?
Switch between the seven languages from “Language” in the app’s menu. If you’re logged in, your choice is saved to your account too.
