Mobitool

200+ tools in one app, with no ads and no sign-up. A PDF editor with signatures, a document scanner, file transfer between iPhone and computer, text from photos, photo and video compression, exchange rates, QR codes and internet checks. Almost everything works offline. On the first launch the app asks what you do and builds the home screen from the tools that fit. The rest sit in a searchable catalog. DOCUMENTS AND PDF • PDF editor: sign, fill in forms, edit text, add drawings and stamps, highlight or redact text, manage pages • Document scanner: finds the sheet edges in a photo, straightens the perspective and gives a PDF that looks scanned • Text from photos, screenshots and scans in English and Russian, read on the device, burned-in subtitles to SRT • Merge and compress PDF, images to PDF and back, remove the password from a file you can open • Document converter: DOCX, ODT, RTF, EPUB, FB2, HTML, Markdown and TXT FILE TRANSFER • Files and text between phones and computers on the same Wi-Fi, compatible with LocalSend • Over the internet by a code or a QR with end-to-end encryption: devices connect directly, and when they cannot, the stream goes through a server that stores nothing • A browser link for a device without the app PHOTO, VIDEO AND AUDIO • Shrink photos to a file size, convert images including HEIC, edit photos, strip the location • Passport and visa photos with a 10×15 cm print sheet • Multitrack video editor with export up to 4K, video converter, GIF, frame from video, audio editor and converter MONEY AND EVERYDAY • Rates for 160+ currencies and crypto, loans, savings, discount and VAT, splitting the bill • QR codes for links, Wi-Fi and contacts, a QR and barcode scanner • Percentages, calculator, units, date calculator, clothing sizes, renovation, timer, world clock INTERNET AND NETWORK • Speed test and a connection check that finds step by step why the internet does not work • Is a site down for everyone, Bluetooth radar for lost earbuds and trackers that follow you • Ping, traceroute, DNS, whois, port and LAN scanners, public IP check, subnet calculator SECURITY • Password generator, leaked password check, 2FA codes AND MORE • Developer tools: JSON, Base64, hashes, regular expressions, JWT, cron, SPF, DKIM and DMARC checks • Electronics and 3D printing: Ohm's law, resistor color code, filament picker, print cost • Sensors: ruler, level, compass, sound meter, tuner, pedometer, light meter • Health: BMI, calories and macros, heart rate zones, workout timer, sleep, water Calculations run on the device. Only the tools that need the internet by their nature, such as exchange rates, the speed test and file transfer, go online, and they talk to the service named in the tool. The app sends usage statistics and crash reports to Google Firebase: which screens and tools were opened. What you type and the files you open are not sent.
