CrowdTools

The invoice gives you the gross amount; the figure you need is net. Pages 3 to 7 of the bank statement go to the accountant, the rest does not. CrowdTools is a toolbox for jobs like that: small calculators and PDF tools, all behind one home screen with a search box. Type what you are after and the tool opens. No account, no internet connection. The box grows. Every update adds tools, built to the same rules as everything already in it. Whatever small job comes next, there is a fair chance it is already in here. WHAT IS IN IT TODAY Calculators • VAT — net ↔ gross, at 19 %, 7 %, 0 % or a rate you set. The figures always reconcile. • Percentage — share, change, "what percentage of". • Tip — work out the tip, round the total up, split it across the table. • Units — length, weight, temperature, area, volume, data. • Loan — annuity loans. Set the term or set the monthly payment, with a full repayment plan year by year. PDF • Extract pages — type "3-7, 12", get a new PDF. • Delete pages — tap the pages you want gone. • Merge — several PDFs into one. • Arrange & rotate — reorder, rotate, discard. • Images → PDF — photos and scans into one document. Pin the tools you reach for often to the top. Search knows the words you actually use: "VAT", "sales tax" and "gross" all lead to the same calculator. HOW THE APP WORKS Everything stays on the device — invoices, contracts, payslips. No account, no sign-up, no analytics, no ads: the app contains no networking code at all. Nothing is uploaded, and in flight mode everything works exactly the same. PDF originals are never modified. Every tool writes a new file and leaves the original exactly as it was. Results appear as you type. There is no calculate button. German and English, both complete. The language can be switched in Settings and takes effect immediately, without a restart. Light and dark, following the system or fixed to your choice. iPhone and iPad. Free. Nothing is locked. From ServerCrowd GmbH in Germany.
