Vaktberegner
Read full descriptionHide full description
Did you get paid correctly? Take a photo of your payslip — Vaktberegner compares it with the collective agreement or the law for your industry and shows, in kroner, what may be missing. If it finds money, it drafts a ready-to-send claim to your employer. For shift workers in Norway: security guards, health and care (municipal, hospital, private), retail and commerce, bus and coach, construction, cleaning, hotels and restaurants (including the Riksavtalen agreement), warehousing and logistics, road freight, electrical trades, shipyard work, car workshop work, kindergarten, pharmacy, hairdressing, agriculture and the Norwegian state sector. Also for personal trainers and instructors. The app is honest about what it knows and what it does not: where your rates depend on your employer being bound by the agreement, it says so plainly. If your employment contract has its own rates, it uses those. Features: • The app reads your payslip from a photo and answers in under a minute. 5 photo readings free per month, unlimited (Pro) • Shift calendar that calculates your pay before the payslip arrives • Extra shifts for part-time staff are treated as additional work, not overtime — as the rules actually say • Your pay year: the year summed up as cards you can share. Free • Ready-made claim letter when something is missing, "ask your employer" when coverage is unclear (Pro) • Your next seniority step: the app follows your ladder, tells you when it is due, and what it is worth per month. Available for security guards, bus, and health and care • Documentation for part-time staff working beyond contract, Working Environment Act § 14-4 a • Hourly-rate calculator for freelancers • Import your roster from the calendar • The whole Economy tab: history and forecast, holiday pay, tax, sick pay, seniority, working-hours watchdog and hourly rate. Free • Share your month as an image, a PDF or a spreadsheet, also with your own photo or video behind it. Free • Pay assistant that works with your own numbers. 3 questions free per month, unlimited (Pro) • Shifts, calculations and history stay on your phone and work without a connection. No account • Reading a payslip or a roster photo needs a connection. The image is sent to a service that interprets it, and is not stored anywhere VAKTBEREGNER PRO Recording shifts, seeing what they should have paid, checking your payslip, the whole Economy tab, sharing, export and roster import are free, with no cap on the number of shifts. Pro is what comes on top: • Live shift on the Lock Screen — time left of the shift and what you have earned so far, without opening the app • Reminder before your shift — the app knows when the shift starts and what it is worth, and tells you in good time • Claim letter to your employer — the shortfall set out as a document you can send, shift by shift • Final settlement letter — your last settlement set out as a letter: holiday pay, wages not yet paid, time off in lieu and supplements • Unlimited photo reading — payslips and rosters from a photo as often as you like. Without Pro: 5 per month • Unlimited assistant — ask as much as you like. Without Pro: 3 questions per month Price: NOK 49 per month or NOK 399 per year. New subscribers get a 7-day free trial; unless you cancel before it ends, the subscription continues at the price above. The subscription renews automatically until you cancel. Cancel at least 24 hours before the period ends, under Subscriptions in your Apple Account settings. If you buy the subscription while the trial is running, the remainder of the trial is forfeited. If you already have the app, you keep claim letters for free. Photo reading and the assistant have the same monthly free limit for everyone, since each use costs us money.

STACK

STACK is a chip tray for a real poker game. You deal real cards; STACK keeps the money straight. Everyone at the table opens the app, types the same four-letter code, and sees the same chips. Nothing to buy, nothing to count, nothing to lose down the side of the sofa. WHAT IT DOES • Tracks every stack, the pot, and the blinds • Knows whose turn it is, so nobody has to ask • Handles side pots when someone is all in — the part everyone gets wrong • Works out who owes who at the end, in the fewest payments possible • Re-buy any time; it all gets counted at settle-up BUILT FOR A REAL TABLE The app never sees your cards. You shuffle, you deal, you read each other across the table. STACK holds the chips and does the arithmetic, so the game stops pausing while five people argue about the maths. DROPPED SIGNAL? NO PROBLEM Phones lock and wifi drops. STACK puts you straight back in your seat, mid-hand, with your stack intact. NO ACCOUNTS, NO ADS No sign-up, no email address, no advertising, no tracking. Open it, type a code, play.
