About Deadline Guardian
Deadline Guardian is your hub for everything that recurs in life – inspections, services, insurance, vaccinations, contracts. Create a device (car, home, pet), add a deadline, and the app warns you in advance – up to 30 days ahead on legal templates. You set the lead time per item, even on the due date itself. After completing it, log the supplier, cost and a photo of the receipt – the app calculates the next due date. WHAT DEADLINE GUARDIAN TRACKS • Vehicle – periodic inspection, mandatory liability insurance, tire swap, oil, brake fluid, timing belt • Home – boiler, lightning protection, fire extinguishers, elevator, septic / wastewater, solar PV, AC, heat pump • Documents – passport, driving licence, tax return, road toll, insurance policies • Health – preventive checkups, vaccinations, mammography, dentist • Family – birthdays, anniversaries, child vaccinations, growth log • Pets – vaccines, deworming, flea/tick, vet visits, microchip • Pool – pH, alkalinity, shock chlorination, winterizing, sand replacement • Garden – fertilizing, pruning, watering, mulching WHY DEADLINE GUARDIAN – 100+ universal templates plus country packs for Czechia, Slovakia, Germany, Austria and Switzerland – Reminders with enough lead time – up to 30 days ahead on legal templates, and you set it per item – Sync across devices (phone ↔ tablet ↔ web) with email sign-in – Cost + supplier per completion – see your annual cost of running a house or car – Correct legal intervals per country – HU/"TÜV", Pickerl, MFK, STK, chimney sweep, vignettes; country picker in Settings – No ads, no tracking – telemetry is anonymous and toggleable – Free at launch – no subscription needed for normal use TYPICAL USE "I missed my STK because I didn't note the date" – never again. The app reminds you well ahead, and you decide how early. "When did we last inspect the lightning rod?" – history per item. Photo of the protocol, invoice, service company name. "How much does my car cost per year?" – monthly / yearly costs grouped by device. "My calendar is full of deadlines" – all of them in one app, push notifications at the right time.

What’s new
Version 1.2.2 · Updated September 10, 2026
Fix for the first-run setup. • You could pick more areas than the free plan can store, so some tracked things never reached your cloud backup. The picker now matches your plan – nothing gets lost. • Sample data no longer takes up room in your limit. Thanks for the feedback: [email protected]
