A fishing-spot map from a captain, 170k people viewed it, 2,400 installed it: Malaysian fishing app Kail

In Langkawi, a 29-year-old asked a local captain to mark his fishing spots on a map and turned it into a Malay-language fishing app. One TikTok video got 170k views, and the comments kept asking "does my area have any?" Three months later, however, the app had only 2,373 total installs on Google Play. It proves what anglers want, and also that wanting isn't enough. Below: what it is, where the traffic came from, why it didn't stick, and whether Indonesia, the Philippines, and Thailand could support a copy.

A video that says "don't blame me if you come back empty-handed again"

In Jul 2026 31, a TikTok account with barely a thousand followers, @palasgo, posted a 66-second video with one line of caption: "Kumpau lagi taktau la." Kumpau is Malaysian angler slang for going out to sea and catching nothing. The line roughly means "if I come back empty-handed like this, I've got nothing to say." The video shows a chart covered in fishing spots.

By Nov 6, the video had 170,844 views, 8,855 likes, and 3,049 shares (TikTok, 11-06). The next day, Kail went live on Google Play, and the account posted an image-and-text post that got 44k views. Almost every comment under both videos asked the same thing:

"area kelantan ade jgk ke": does Kelantan have it too? "Sabah sarawak dah ada belum?": do Sabah and Sarawak have it yet? "lumut Perak ade x": does Lumut in Perak have it? "udah mcm pokemon go": it's like Pokémon Go now.

The other half asked: "iOS ada ke" (is there an iOS version?), "kena bayar ke" (do you have to pay?), "ada langganan ke" (is there a subscription?). Then a comment that kept showing up: "Kosong je": it's empty. "done download.. X nmpk spot pon": downloaded it, and I can't see a single spot.

What it is and who made it

Kail - Malaysia Fishing App is an "offline-first" fishing assistant for Malaysia: offline charts (navigation markers, boat ramps, piers), tides (the store page uses the Malay term pasang surut), bite times calculated from moon and sun phases, weather and sea warnings, trolling and longline (rawai) route logging, anchor alarms, and a catch log. Two other features are things global big players won't do: a Kiblat compass pointing toward Mecca, and an Islamic calendar using data from Malaysia's JAKIM. The real selling point is in the caption of the second video: "Many Malaysian tekong (captains) work with us." The spots come from captains.

The developer is palasgo, a sole proprietorship called PALAS NETWORK based in Kuala Teriang, Langkawi, which originally made WordPress plugins. The app was built by Khairul, 29 years old, from Batu Ara village in Langkawi. His Facebook says he works in aviation operations in Langkawi, so we infer this is a personal project built after hours. The iOS version only launched in Sep 9, and as of 11-06 it still has no ratings.

Monetization is ads plus in-app purchases. The Play listing shows in-app purchases at $5.99–59.99 each, and the store page says you can "unlock paid spots." Whether anyone has bought them, and how many, isn't visible from outside.

Did it really take off? No. The chart bar was just low.

It appeared on the "gaining traction" list because 11-06 ranked #64,10-29 on Malaysia's Google Play Sports free chart, and once reached #19. But that chart is dominated in Malaysia by football, cricket score, and livestream apps. A fishing app with a few dozen installs a day can squeeze into the top 60.

Data: Google Play installs, collected daily through 11-06; the two August figures are third-party estimates.

Put the 170k views and 3,049 shares side by side and conversion is very poor: during the weeks the video was viral, installs only reached a few hundred. One reason was that only the Android version existed at the time, and more than a dozen comments asked about iOS. Another was that people who installed it saw an empty map when they opened it.

Where users came from: one video, one politician

Besides the TikTok video above, the second wave of traffic came from a local public figure. In Oct 25, former Kuah state assemblyman Nor Saidi Nanyan posted a video on Facebook titled "ANAK PULAU HEBAT!" (Island kids are amazing!):

"Meet Khairul, 29 years old, a young man from Batu Ara village in Langkawi... Langkawi alone has over 200 fishing spots marked!... Let's all support local kids' products! Search Kail Malaysia Fishing on Google Play to download."

The post got 185 reactions and 15 shares on Facebook. The same clip posted to TikTok got 32k views, and it was also posted on Instagram. Five days later, installs started to jump. The post also said "already over 20,000 users," but Play shows only about 2,400 total installs, and iOS has no ratings. The two don't match. Possibly viewers were counted as users, or it was an exaggeration in passing. Unverified.

We infer that most of the rest of the traffic came from store search: the title directly says "Malaysia Fishing App," and the description is stuffed with Malay terms like pasang surut, waktu makan ikan (bite times), and kiblat. We found no evidence of paid advertising, no media coverage, and no one discussing it on X.

Who it's competing with

Malaysia's fishing tools aren't empty.

The takeaway is blunt: tides, fish-activity times, and nautical charts were already available in Fishing Points a decade ago, and it ranks higher than Kail. The one thing Kail has that nobody else does is "local spots from boat captains." The TikTok comments prove that's the only thing pulling people in.

Where it falls short

Spots only cover the home backyard. The captains' spots are concentrated in Langkawi and the north. Anglers in Kelantan, Johor, Sabah, Sarawak, and Pahang open the app and see nothing. Even on Langkawi, people say "when I open it, it's empty." It's likely some spots sit behind the paywall, so users can't tell "no spots here" from "pay to see them." The most valuable part wasn't fully built out before promotion began, so most of the 170k views were wasted.

Android only. When the video went viral, there was no iOS version. iOS didn't arrive until September, by which point the buzz had already faded.

The money is invisible. There are no ratings, no reviews, and no public revenue figures. Whether anyone buys the $5.99–59.99 paid spots is the biggest unknown in this whole story.

If it were you

Grade B: worth a test, but don't copy Kail itself, and don't go head-to-head with it in Malaysia. It proves that the sea-fishing community in Southeast Asia will stop, watch, share, and ask questions about "spots locals don't tell you about." It does not prove that these people will pay, or that one person can cover an entire country's coastline on their own.

Who it suits: people who fish themselves, who have relationships with local boat captains and tackle shops, and who speak the local language. Indonesia, the Philippines, Thailand, and Vietnam have long coastlines and large sea-fishing populations, and the high view counts on Navionics marking tutorials on TikTok show anglers are already logging spots by hand. Beyond fishing, dive sites, surf breaks, and river fishing spots follow the same structure: the data sits with a few locals and spreads by word of mouth.

Who it doesn't suit: people who don't know a single boat captain and just want to make the tide and bite-time algorithms prettier. That part is already done by Fishing Points, and it's free. Also not for anyone expecting quick revenue: three months in, Kail still shows no sign that anyone is paying.

How to build it: get the data first, then write code. Recruit three to five captains and cover one region at a time, releasing each region only after it has dozens of spots at minimum. On the first screen, show users that spots exist in their area, even if only the rough location is visible and exact coordinates cost money. Make the paywall clear: "This area has 80 spots, unlock for ¥X," so nobody thinks it's empty. Launch on Android and iOS together. Offer captains a revenue share or ad placements on their boats so they keep adding spots.

How to get users: copy Kail's video. Film a chart covered in spots and use one piece of local angler slang, then post it to TikTok and Facebook fishing groups. Let comments decide which area to cover next based on where interest is strongest. Once a region is fully covered, reach out to the local captains, tackle shops, or local personalities with a post like "an app built by a local." Kail got its entire audience from one video and one politician, at zero cost.

Timing: in many Southeast Asian waters, monsoon season keeps small boats off the water. Likely, launch and spot coverage should be finished before the local peak season begins. Kail hasn't covered Malaysia's east coast or East Malaysia yet, so if someone wants to do this in Malaysia, the window is open until Kail gets there.

Signs you're reading this wrong: (1) you cover a whole region, the videos reach 100k views, and in a month almost nobody buys a paid spot, meaning anglers just want to look for free and this is a community, not a business; (2) captains give you a batch of spots and then stop updating, or captains turn around and forbid public release, cutting off the data supply; (3) Kail's Play installs stay at a few dozen a day three months later, even though it has covered the whole country, meaning coverage isn't the problem and demand is simply this small.
