Bike navigation, radar and a diary. In one app.
Ridena runs in your browser — open the site, add it to your home screen and ride. No app store, no installation.
Not sure your phone can handle it? Will my phone handle it? — a 10-second test, no sign-up.
You see the Varia radar on your phone
Cars and cyclists behind you as a strip at the edge of the screen, with an audible warning. No bike computer needed.
One radar, several phones
Your buddy sees the same cars on their screen as you do — just send them the code. No other app can do this.
Everything in one app
Navigation, recording, weather and diary in one place, on your phone and on your computer. Nothing is transferred by hand.
A step-by-step tour of the app
In the tour the app clicks for itself — it starts a demo ride, sends a car into the radar, opens the weather. You just read the bubbles and tap “Next”.
The tour runs in the live app, not in a video.
What Ridena does
Route planner
Click a route together on the map, or load a GPX.
Read moreHide
You choose how the route is led: cycle routes, fastest, or off-road. And right under the route you see how many metres you will climb — not just the lowest and highest point.
Signed cycle routes are highlighted on the map with their numbers. The planner can follow them and favours them when planning; but you can also tell it you want a route more off-road, or one for road bikes.
Marked cycle routes for the whole of Europe except Russia and Ukraine (47 countries) are stored right in Ridena. They show up in the map straight away, with no waiting for the network. Outside these countries the cycle routes are loaded from the internet as you ride.

Czechia, Slovakia, Austria, Germany, Poland, Italy, Croatia, France, Slovenia, Hungary, Netherlands, Belgium, Luxembourg, Switzerland, Romania, Serbia, Spain, Great Britain, Sweden, Norway, Finland, Denmark, Portugal, Ireland, Greece, Bulgaria, Lithuania, Latvia, Estonia, Bosnia and Herzegovina, Montenegro, North Macedonia, Albania, Kosovo, Moldova, Belarus, Turkey, Georgia, Iceland, Cyprus, Malta, Andorra, Liechtenstein, Monaco, Isle of Man, Guernsey and Jersey, Faroe Islands.
Turn-by-turn along your route
The map rotates with your heading and the app alerts you before every turn.
Read moreHide
If you miss a turn, the app beeps — and one tap plots your way back to the route.
The map along the route is downloaded ahead, so navigation works without signal too.
A stop along the way
Got hungry and there is a shop just off the route? Ridena takes you there and then brings you back to the route, and the rest of the route stays as it was.
Read moreHide
In the same way you find a shelter when it starts to rain, or food, water, a bike shop or a pharmacy. And if you want somewhere else, just hold a finger on the map where Ridena should take you.
Tap a marker on the map to see what the place is and how far it lies from the route — for pubs and shops the opening hours too. One button adds it as a route point.
Varia radar, for your buddy too
A strip of cars and cyclists approaching from behind and an audible warning, right on your phone. Your buddy sees the same thing on their screen.
Read moreHide
The closer the car, the lower it shows in the column. The number by the dot is its speed, and the scale was measured in real traffic, not estimated. A fast car is announced more urgently, and on a close pass the whole screen turns red. Remember to turn the volume up.
Your buddy just needs the code: they install nothing and create no account, they open the link, type the code and they are connected.
The radar state travels over the internet, so both phones need signal. After the alpha test, sharing will cost extra.
Weather and rain
A local forecast, a warning when rain is coming, a rain radar right on the map. A guide, not a guarantee.
Read moreHide
Treat the weather as a hint, not a certainty. The forecast and the rain radar are computed by weather models, and as we all know, those sometimes miss. Ridena honestly shows you what the models say and warns you when rain is coming. Whether to set off is up to you and a look out of the window.
Ride recording and diary
Recording starts by itself once you move and survives closing the app. The diary holds stats, photos and videos, yearly overviews and a public link to the ride.
Read moreHide
Until the ride ends, the recording can be exported as GPX. You sort rides into road, gravel and MTB, and a saved ride can be edited and trimmed.
With a ride you can also save a short video shot along the way — it plays in the entry, and the map replay stops at it. After the alpha test, more videos on a single ride will cost extra.
Plan a trip for me
No idea where to go? Say how many hours you want to ride, whether you want hills and whether you ride an e-bike — and the app puts together a loop from here and back.
Read moreHide
It sticks to signed cycle routes where it can. It works the kilometres out from the hours using your own pace from the diary.
My places and location
Save a spring or a pub to the map — and send where you are with one tap.
Read moreHide
Saved places stay with your account, on your next phone too.
Send your location before you set off as a “meet me here”, or while riding by tapping your own arrow on the map. You also see how precisely the phone fixed the position, so you never send anyone to a place you are not. The coordinates can also be read out over the phone.
Everything you read here already works in the app — none of it is a plan. Testing is invite-only for now; we go through applications by hand.
I want to test RidenaPlan on a computer, ride with your phone
It is one and the same web app at the same address — it just notices you are at a computer and adapts. A big screen is comfortable for planning and browsing; on the bike you ride with your phone. The account is shared, so whatever you plan on the computer is on your phone right away. And you can plan right on your phone — you can do it all with a finger, it's just more comfortable at a computer.
A route planner across the whole monitor
By clicking on the map, not with a finger. A point grab and drag straight across the map, and tapping the route adds a detour to it.
Read moreHide
The routing sticks to cycleways, places are found by name, and a route in progress isn't lost even if you close the window.
And above all you know what you're in for before you set off: an elevation profile with total climbing, a time estimate worked out from your own rides — not from a table —, surfaces colour-coded (asphalt / gravel / off-road) and shaded relief that shows the hills at a glance.
Search takes coordinates and links too: into the same box you paste a place name, coordinates in the usual notations, or simply a Google Maps link.
Check for closures before you leave: before you save a route, the app walks it against live OpenStreetMap data and tells you whether any section is closed or dug up. And when it finds nothing, it says so.
The route reaches your phone by itself
You save it to My routes and you have it on your phone. No emailing GPX files, no cable — routes live with your account.
Read moreHide
And when a route doesn't start at your door, every saved one has a button for “drive to the start” — one tap opens Google Maps with driving directions to the starting point.
If you prefer GPX, you can still load one from a file.
Tell the surface by its colour
The route is coloured by what it runs on — before you even set off. So you know in advance whether asphalt awaits you, or a stretch of gravel that calls for a different bike.
Read moreHide
For a specific route the app works out what percentage falls on which surface. In Czechia, Slovakia and Austria the surfaces are drawn instantly on top of that — we have them pre-computed on our own server, so there is nothing to wait for.
A diary worth opening on a big screen
Rides as a grid of thumbnails with photos. In the detail a replay of the ride across the map, elevation and speed charts, the weather at the time, and a photo gallery pinned to the route.
Read moreHide
You can edit a saved ride here too: the name, rating and note get filled in calmly at a keyboard, not one-handed in a car park. Though you can do that too, if you want.
The public link to a ride stays the same even after renaming.
Account and profile management
A profile photo with its crop, your name, a password change and an overview of what we hold about you. Your own public profile with all your public rides at ridena.cz/u/your-nickname.
What the computer deliberately lacks
No Ride button, no radar, no ride recording. Nobody rides at a monitor, so Ridena doesn't show them and doesn't get in your way with them.
The diary and the planner are unchanged.
Suicide by bicycle
A real public ride, not a picture. A 3D satellite map with ride replay, an elevation profile, a speed chart, the temperature during the ride and photos pinned to the route.
What it runs on and what to bring

Android + Chrome
Android 10 or newer, 12+ recommended
The full kit, no limits — navigation, recording, the diary, weather and the Garmin Varia radar.
Read moreHide
Chrome updates itself from the Play Store, just make sure you haven't turned that off.
Chrome offers the home screen icon by itself, or you can add it via ⋮ → Add to Home screen.
iPhone without a radar
iOS 16.4 or newer
Navigation, ride recording, the diary and the weather all work right away.
Without the radar — nothing to install, nothing to sort out.

The app runs in any browser. To put an icon on your home screen, use Safari and Share → Add to Home Screen.
iPhone with a Varia radar
iOS 16.4 or newer
With a Varia radar — you set up a free add-on from the App Store once.
Read moreHide
You need the free beacio add-on from the App Store, and you have to open Ridena in Safari (not from the home screen icon). It takes a couple of minutes.
On iPhone every browser is Safari underneath, but the add-on is a Safari extension — which is why it does not work in Chrome.
The newer the system, the longer you'll have all of Ridena — on the oldest supported versions, new features may stop reaching you over time. On an iPhone, Safari only updates together with the whole system, not on its own.
What to bring on the bike and what to expect while riding
A phone and a handlebar mount — the app has to be visible.
A power bank or a dynamo for longer trips — the screen stays on for the whole ride, so expect higher battery use.
Optionally a Garmin Varia radar (RTL515/516 and relatives) — everything else works without one. On an iPhone you need the free beacio add-on.
Mobile data, only when you share the radar with a buddy — the radar state travels over the internet. Navigation, recording and the downloaded map work without signal too; recording runs on GPS, which needs no carrier signal.
The app has to stay on screen — navigation and ride recording only work with the app in the foreground; in the background they stop.
Read moreHide
Ridena runs in a browser, and a browser only works while it is visible. Navigation and ride recording therefore only work with the app in the foreground — in the background it stops.
At a stop you can switch away, to the camera for instance — but then come back to the app. Otherwise you have no instructions on where to go, and the recording is left with a hole: a straight line between the place you left and the place you came back to — not the route you actually rode.
Music and audiobooks keep playing — Ridena doesn't touch what you're listening to. It borrows the sound only for its alerts and gives it right back — your music comes back up to its original volume by itself.
Nothing more. The app installs from the browser, no app store involved.
Got a phone, a handlebar mount and the will to report what broke? That is all the testing takes.
I want to test RidenaAlpha testers get the full version free forever — but it's not a gift, it's what we give back for testing.
What you get
The full version, free forever — not as a gift, but in return for testing.

Ridena will be paid. You'll pay per period — 30 / 90 / 180 / 365 days — not a year-round subscription; a seasonal cyclist shouldn't pay for winter. We're not quoting prices yet.
After the alpha test, radar sharing will cost extra, depending on how many phones you share with at once. Testers with the lifetime version keep it.
What we expect
Ride with the app and write at least once about what doesn't work or is missing. Anyone who sends nothing during the whole test doesn't get the lifetime version and pays like everyone else.
Read moreHide
Feedback takes a minute: in the menu (☰) there is an item Feedback — you pick Bug or Idea and write a few sentences, even from the car park after a ride. Messages are matched to your account email, so it's easy to see afterwards who tested.
When the app crashes, it reports it to us by itself — including the version and the type of phone. You only write about what annoys you or what is missing.
How it works
We go through applications by hand and get back to you by email with an invitation. We take a limited number of testers so we can keep up with what they send.
Read moreHide
Ridena is in alpha: something may break or change. We say so up front, so nobody expects a finished product.
Why we do it this way
Ridena grows from what testers report from the road. What gets added is partly up to you.
Read moreHide
What began as the answer to one problem is now heading to other cyclists. That is why the alpha is invite-only, and why feedback is a condition rather than a courtesy.
The deal is simple: you test and write to us, we give you the app forever.

Who is behind it
There are two of us behind Ridena — Karin and Tom. We wanted navigation, radar and a diary together on the bike, at a price that makes sense for a hobby cyclist — and nothing like that existed. So we built it ourselves. Ridena runs in a browser, not in an app store, and you can take your rides with you any time. And you'll be able to subscribe only for the periods you actually ride — you won't pay for the months the bike sits in the cellar.
Your data stays yours
Rides are private until you make them public yourself. A public link exists only when you ask for it, and the privacy zone hides where you live on it.
Nothing is locked in. You can download your GPX and photos any time and leave.
Your data sits on a server in the Czech Republic. We use your email only for signing in and for arranging the testing.
Details in the the privacy policy.
