A car collecting game for iPhone
Spot it.
Scan it.
Race it.
Every car you pass on the street is a card waiting to be caught. Photograph real cars with the in-app camera, build a collection ranked by how many were actually made, then send your best five into automated races.
The loop
How it works
Three steps, always in this order. You can't race a car you haven't seen with your own eyes.
Spot
Walk, drive, wait at a red light. Anything on four wheels in the real world can be caught: a daily commuter, a weekend roadster, a supercar parked downtown.
Scan
Point the StreetCaught camera at the car. The app identifies the model and generation and turns it into a card with its real specs, its rarity and a random finish.
Race
Pick five cards for five events. You don't drive: the race is simulated from each car's stats, the track and the surface. Your job is choosing the right car for each event.
Rule 1 · Rarity
Rarity comes from the factory
A card's tier is set by how many units of that generation were really built. It never depends on luck or on the player. Common cars are common because the streets are full of them.
| Tier | Units produced | Neon glow | Typical cars | Scan XP |
|---|---|---|---|---|
| Common | 300,001+ | None | High-volume sedans and SUVs | 10 |
| Uncommon | 100,001 – 300,000 | None | Everyday models late in their run | 20 |
| Rare | 20,001 – 100,000 | None | Production sports cars | 40 |
| Epic | 3,001 – 20,000 | Violet | Focused sports cars | 90 |
| Legendary | 1,001 – 3,000 | Gold, sweeping | Supercars | 210 |
| Mythic | 51 – 1,000 | Red, sweeping | Hypercars | 510 |
| One-off | 50 or fewer | Pink, sweeping | One-offs and prototypes | 1,200 |
From Epic up, the card glows in its tier color. From Legendary up, a brighter spot slowly travels around the frame. The first time you catch a model, its XP is tripled.
Classics get a wooden frame
A car becomes a classic 30 years after its generation stopped being built. The end of production counts, not the start, so even the last car off the line is 30. Nobody picks favourites: it's an age, and every January 1st another year of cars joins the club.
A classic trades its tier border for a thicker wooden frame with real grain. The tier still shows in the text, the glow and the word at the bottom of the card.
| Classic today | Built until | Tier |
|---|---|---|
| Ferrari F40 | 1992 | Mythic |
| Lamborghini Countach LP400 | 1978 | Mythic |
| BMW M3 (E30) | 1991 | Legendary |
| DeLorean DMC-12 | 1983 | Mythic |
237 models in the catalog are classics today.
Where the real production figure is unknown, the card carries a small EST. badge. Estimated entries never land above Rare: the top tiers are reserved for cars whose numbers have been checked by hand.
Rule 2 · Finishes
Two things on every card
Rarity belongs to the car. The finish belongs to your copy, rolled fresh on every scan. A holo Corolla is possible, and that's on purpose. The border tells you the tier, the background tells you the finish.
Finish odds per scan
The background wears the tier
Carbon, Forged and Holo cards take the colour of the car's tier. A Legendary holo glows gold, a Mythic forged card has red resin flakes. Gold and Silver keep their brushed metal.
A second roll on top
One card in a hundred that already has a finish also gets a holo foil laid over it: a Gold Holo, a Carbon Holo. It keeps its own background and adds the foil that lights up when the light passes. On a Minimal card it shows as a ★.
Tilt to see it
A holo foil only shows inside the band of light that crosses the card when you tilt your phone. Carbon is a material: you see it even in the shade, and the light adds a shine on top. Holo patterns carry a number from 0 to 999, so no two copies shine the same way.
Full or Minimal
Full shows everything: the car picture running edge to edge with its name printed on it, generation and year, the four stats with bars, the real specs (0-100 km/h, top speed, power, torque, redline, drive, fuel, units built) and the money block (MSRP and market range).
Minimal keeps only what you need to pick a car: the picture with the model name, the drivetrain, the four stats and the Power. That's the view for comparing five cars at a glance. Switch between them in the garage.
Power and its letter
The number in the bottom corner is the car's Power, from 20 to 100. It's what counts against your hand budget. The letter says the same thing at a glance:
| Letter | F | E | D | C | B | A | S |
|---|---|---|---|---|---|---|---|
| Power | 20–39 | 40–49 | 50–59 | 60–69 | 70–79 | 80–89 | 90+ |
Finishes are cosmetic. They never change race stats, so scanning the same car every day doesn't buy you speed.
Rule 3 · Racing
Real specs in, four stats out
Every card lists the car's real figures: 0–100 km/h, top speed, power, torque, redline, drivetrain. The game turns them into four stats from 1 to 100.
Acceleration
From the 0–100 km/h time. Quicker off the line, higher score.
110 − 7.5 × t(0–100)Top speed
Scaled from 120 km/h (1) to 350 km/h (100).
(vmax − 120) / 230 × 100Grip
Weight, drivetrain and tires. AWD +8, 4WD +6, RWD +2, performance tires +10, off-road tires +4.
50 + bonuses − (kg − 1400)/40Off-road
Ground clearance, 4WD +20, off-road tires +15, performance tires −10.
20 + (clearance − 120)/2 + bonusesEach event weighs the stats differently
This is where the choice happens. A drag monster can lose a slalom to a light roadster.
| Event | ACC | SPD | GRP | OFF |
|---|
| Surface | Grip multiplier | AWD bonus |
|---|---|---|
| Dry asphalt | × 1.00 | — |
| Wet asphalt | × 0.85 | +0.10 |
| Gravel | × 0.60 | +0.15 |
| Snow or ice | × 0.45 | +0.20 |
A match is five events
- One card per event, each card used once.
- Stay under the Power limit. Every car has a Power value from 20 to 100, built from its stats. The five cards in your hand must fit in your budget.
- Your budget grows with your level: 250 at level 1, rising to 400 at level 30.
- A ±2% driver factor is rolled each race, so a tiny gap doesn't always go the same way.
- Points, not just wins. A win is worth 50 points, plus up to 50 more for the size of the gap. A car that gets stuck scores nothing.
- Races play in real time. A 12.40 s run takes 12.40 s on screen. Hold your finger on the track to speed it up (×2 to ×16), or skip to the finish.
A real race from the game
Hill climb · Snow
Same physics, track and cars as the app. Pick two cars and a surface: on snow, a supercar with 105 mm of ground clearance and performance tires doesn't get far, while on dry asphalt the result flips.
Rule 4 · Campaign
Six countries, one new problem each
Ten levels per country, five races per level. The events and the rival's hand are fixed, so you can study them before you pick your five cards. Each country opens at a player level and adds one condition you haven't had to handle yet.
| Country | What it adds | Opens at level | Power cap |
|---|---|---|---|
| Mexico | Dry asphalt only. Learn the events. | 1 | 276 |
| United States | Rain and long straights | 6 | 302 |
| Japan | Tight mountain roads | 11 | 328 |
| Germany | Flat-out top speed | 16 | 353 |
| Norway | Snow, ice and the first rally stages | 21 | 379 |
| Kenya | Dirt, gravel and rally for real | 26 | 400 |
Share of the points
Stars come from your share of the points, not the number of events won. Dominating three events beats scraping four. Three stars need 80% of the points.
A part at levels 5 and 10
Three stars on level 5 and level 10 of a country earn a part, the first time only. The level 10 part comes with much better odds.
Kenya, level 10
The last level of the campaign gives a guaranteed Legendary part. It's the only place in the game where a Legendary part drops.
Coming back to an early country with a stronger garage? Your hand is capped at that country's Power, so it stays a real race.
Rule 5 · The Workshop
Upgrade, merge, fit parts
Duplicates aren't wasted. Catch the same model again, any generation, and it becomes fuel for the Workshop. Everything is stored per model: if you own three Civics, you sacrifice two to upgrade "the Civic", and that's the one you race.
Three axes, three levels each
More power.
Level 1 opens the Turbo slot
Level 3 opens the Transmission slot
Less mass.
Level 1 opens the Carbon slot
Level 3 opens the Wheels slot
More cornering grip, better brakes.
Level 1 opens the Suspension slot
Level 3 opens the Aero slot
| Level | Engine power | Weight | Chassis grip | Duplicates | Coins |
|---|---|---|---|---|---|
| 1 | +4% | −4% | +4% | 1 | Power × 11 |
| 2 | +9% | −9% | +9% | 2 | Power × 27 |
| 3 | +15% | −15% | +15% | 3 | Power × 63 |
Coin costs follow the car's Power, so tuning a hypercar costs far more than tuning a city car. A tuned car's Power goes up too: faster in one event, less room in your hand for the other four.
Parts are real hardware
A part never says "better in the rain". It changes something physical (power, mass, top speed, downforce, launch traction, braking, tire grip on each surface) and the race physics decides where that pays off. A GT wing adds downforce, which helps in corners. A drag race has no corners, so there it only costs you drag.
| GT wing | Circuit | Slalom | Hill | Drag 400 | Drag 1 km |
|---|---|---|---|---|---|
| Lap time | −9.8% | −10.8% | −4.7% | +0.4% | +0.9% |
| Rare tires | Dry circuit | Wet circuit | Gravel rally | Snow rally |
|---|---|---|---|---|
| Slicks | −4.9% | +7.9% | +10.6% | stuck |
| Wet | +1.1% | −6.7% | +1.5% | −2.3% |
| Studded | +3.9% | −1.9% | −2.9% | −10.3% |
| Off-road | +3.0% | −1.3% | −6.7% | −5.5% |
| Drag slicks | +6.2% | +14.8% | +15.0% | stuck |
Change in time, measured in the game's own physics. Negative is faster.
Five tiers, one bigger bonus
Parts come in Common ×1, Uncommon ×1.3, Rare ×1.7, Epic ×2.3 and Legendary ×3. The tier multiplies the bonus, never the penalty: a Legendary slick grips better on dry asphalt and slides exactly as much on snow. From Epic up, most parts become different hardware, like a twin turbo instead of a single.
Six big, two small
Each big slot takes its own family: turbo, transmission, carbon, wheels, suspension, aero. Small slots take brakes, an exhaust or a set of tires. Every car has one small slot from the start, and a second one can be bought for a single model. A part can only sit on one car at a time.
Won after races
Races drop parts up to Epic: Common 56%, Uncommon 28%, Rare 12%, Epic 4%. Legendary parts never drop from ordinary races. The campaign's last level is the only way to get one.
Rule 6 · The Shop
Three parts a day
The Shop puts three parts on the shelf every 24 hours, each from a different family. Don't like them? Watch an ad to reroll, up to three times a day. That counter is separate from your gauges, so an ad watched for fuel never costs you a reroll.
| Tier | Price | On the shelf |
|---|---|---|
| Common | 300 coins | Often |
| Uncommon | 800 coins | Regularly |
| Rare | 2,000 coins | Sometimes |
| Epic | 6,000 coins | Rarely |
| Legendary | — | Never sold. Earned in the campaign only. |
The shelf comes from the day itself, so closing and reopening the app never reshuffles it.
Rule 7 · Energy & fair play
Two gauges, one honest camera
Scanning and racing each draw from their own gauge. Both fill back up to the top once a day.

- No reused photos. Each image is fingerprinted.
- One scan per car, per place, per 24 hours. Same model, within about 50 m, very similar photo. You can still take the picture; it just won't create a new card.
- Soft signals like time, motion sensors and scans per hour help spot automation.
- Graduated penalties: a warning, then a scanning pause, then removal from the leaderboard.
Questions
FAQ
When can I play?
StreetCaught is in active development and runs on test devices today. It will launch on iPhone first, in English, with French and Spanish to follow.
Can I scan a photo I found online or took earlier?
No. Cards only come from the in-app camera, live. The whole point of a card is that you saw that car yourself.
Why was my scan refused?
Usually one of three reasons: the photo looks like a screen or a print, the image was already used, or you already scanned that car in the same spot in the last 24 hours. A refused scan never costs a photo.
Does a holo or gold card race faster?
No. Finishes are purely cosmetic. Races depend on the car's stats, its upgrades, the event and the surface.
How do you know how many cars were built?
Hand-checked entries use real production figures for each generation. For the rest, the figure is estimated and the card shows an EST. badge. Estimated cars never go above Rare.
What happens if I delete a card?
The card is gone, but the car stays marked as seen in your Dex forever.
Do parts really make a car faster?
Yes. Parts change the car's real physics (power, weight, downforce, braking, tire grip), and the race simulation uses those numbers directly. A fully tuned car is roughly 11% faster for a Common and 20% for a Legendary. The right tires for the surface matter as much as raw power.
How do I get a Legendary part?
Only one way: win level 10 of Kenya, the last level of the campaign, with three stars. Races and the Shop stop at Epic.
What's the point of duplicates?
Duplicates of the same model, any generation, are merged in the Workshop to upgrade that car: 1, then 2, then 3 duplicates plus coins per level. Each new copy is also another roll at a rare finish.
Why can't I put my five best cars in one hand?
Every car has a Power value and your hand has a Power budget tied to your level. Five top cars won't fit. Spend the budget where the event needs it most.
Can I race my friends?
That's next. First asynchronous challenges: you save a hand and friends race it whenever they like. Then a leaderboard, then live duels with hidden hands and events announced up front.
Does the app share my location?
Only an approximate zone is ever shown to other players, never an exact position.
Is it free?
Yes, free to download and play. Optional rewarded ads refill your gauges, and coin packs will be available to buy.
