By Engineer. For People. With Love.
Everyday utilities — cleaners, scanners, remotes, authenticators — have turned into subscription traps full of ads and trackers.
1Buck Apps are the opposite. Each app solves one problem really well, runs on your device whenever it can, and costs about a dollar a week — or nothing at all. Software engineering as a craftsmanship, made affordable for everyone.
Why 1Buck Apps exists
The utility app market has been broken for years.
Cleaners, scanners, VPNs, remotes — the apps everyone needs have become some of the worst-behaved software on the phone. Look at their App Store and Google Play privacy labels and price lists, and it's all there in plain sight.
A pile of trackers
Analytics, attribution and advertising SDKs, several at once. The privacy labels list "Data Used to Track You" — in apps that only need to clean photos or scan a page.
Your files on someone's server
Photos, documents and contacts are uploaded "for processing", often to servers you know nothing about, and kept for who knows how long. Often behind an account you never wanted.
$10-a-week subscriptions
A "free trial" that quietly turns into $6.99–$9.99 a week. At $9.99 a week that is over $500 a year for a utility — often paid by people who forgot to cancel. Most of it pays for the ads that bought the install, not for the app.
Dark patterns everywhere
Close buttons that appear after five seconds, countdown timers, fake "90% off" discounts and paywalls that block the app entirely.
Scare ads that sell fear
"Your iPhone has 13 viruses." "Your battery is damaged." Fake system alerts in ads push people to install a cleaner that cannot do what the ad promised.
Features that do nothing
"RAM boosters", "junk cleaners" and "speed optimizers" that iOS simply doesn't allow any app to perform — animations instead of results.
Principles
Six promises every 1Buck app keeps.
Cheap refers only to the price. Everything else is premium.
Private by design
No analytics, ad or tracking SDKs. On-device whenever possible.
No account
Open the app and use it. No sign-ups, no email walls.
Fair pricing
$0.99 a week, $2.99 a month or $19.99 a year. No trials, no timers.
Free to use
The core of every app works for free. Premium is how you support it.
Real functionality
No fake scans, progress bars or alarms. Only measured results.
Premium craft
Fast, native and polished, made to stand next to the best in its category.
"I wanted utilities I'm not ashamed to use myself — and that I can install on my parents' and my kids' phones without worrying."
The apps
One problem. One great app.
The line grows one carefully built utility at a time.
