Independent app studio
Small apps that each do one job well.
We make focused tools for scanning, invoicing, filming, finding lost earbuds, zooming in and falling asleep. Every app is free to download on the App Store.
The apps
Grouped by what you need them for. Tap one to see screenshots, features and answers to common questions.
Work & documents
Scan, sign, invoice and record without a laptop.
Camera & travel
Zoom further and remember where every photo was taken.
Everyday tools
Small fixes for lost earbuds, long drives and loud crowds.
Sleep & focus
Sound you can build yourself, for nights and deep work.
Game companions
Values, trade calculators and codes for popular Roblox games.
PDF Scanner: Sign & CompressProductivity
Scan it, sign it, send it.
Version 2.0 turns paper into a sharp PDF, then lets you fill and sign it, shrink it for email and copy the text out. Nothing is uploaded.
- Fill and sign. Your signature, text and the date, placed anywhere
- Compress and merge. Big files small enough to email, or many in one
- Image to text. Copy, export to Word or translate into 20+ languages
ZenSleep & Relax
Build the sound you fall asleep to.
Layer rain, fans, ocean and eight colours of noise into a mix that is yours, then let the timer fade it out.
- 78 sounds. Nature, home, travel and noise colours
- Mix up to 10. Set each volume and save the mix
- Screen off. Keeps playing with the phone locked
How we build
NajStudio is a small independent studio. These are the rules every app follows.
One job per app
If a feature does not help that job, it does not ship.
Free to try
Download free. Any upgrade and its price is shown before you pay.
Your data stays put
No sign-up. Your scans, invoices and mixes stay on your device.
Made for Apple devices
Native apps designed for iPhone and iPad, not web pages in a wrapper.
