I spent the last several months building something I wish existed years ago: LocumBook, a mobile app for UK self-employed GP locums to manage the financial side of locum work. If you've done locum work, you know the problem — sessions logged in one spreadsheet, mileage in another, invoices chased over email, and every April a scramble to reconstruct a year's income for self-assessment. LocumBook brings it together: 🔹 Session, mileage and invoice tracking — free 🔹 HMRC self-assessment export (PDF/CSV, MTD-ready) 🔹 NHS Pension Form A, B & SOLO generation 🔹 Calendar import from Lantum/LocumDeck 🔹 Encrypted local backup, biometric app lock, home screen widgets Core tracking is free, with an optional Pro tier (from £3.99/mo, 2-month free trial) for the tax and pension export features. No ads. It's live now on iOS and Android — link in comments. Built by a solo developer, so genuine feedback from anyone doing locum work would mean a lot.
