The software we build and operate.
Mizaf, InvoiceUltra and Mathfinch are our own products, developed and operated in-house. Alongside them, we design and build digital platforms for others — including BeadBrains and Essex London College.
Mizaf is a software product developed and operated by RED LINE SECURITY LIMITED. It helps mosques manage prayer times, announcements, Ramadan timetables and community updates — and gives communities access to trusted, live mosque timings.
Developed and operated by RED LINE SECURITY LIMITED.
Prayer times
Manage and publish daily prayer and jama‘ah times that communities can trust.
Announcements
Share community updates, events and important notices in one place.
Ramadan timetables
Publish seasonal schedules and special timings for the whole month.
Live updates
Give communities accurate, real-time mosque information when it matters.
InvoiceUltra is a native iPhone app developed and operated by RED LINE SECURITY LIMITED. It helps freelancers and small service businesses create professional invoices, track billable work, manage clients and get paid — all on your device, with no sign-up required.
Developed, operated and published on the App Store by RED LINE SECURITY LIMITED.
Mathfinch is a maths learning app developed and operated by RED LINE SECURITY LIMITED. Its 300 lessons follow the national curriculum for England, from Year 1 to A level: each explains one idea, works an example, then gives fresh practice with feedback on the exact mistake. No accounts, no adverts and no tracking — progress stays on the device.
Developed and operated by RED LINE SECURITY LIMITED. Apps for iPhone, iPad and Android are on the way.
Software we’ve delivered for others
Beyond our own products, we design and engineer digital platforms end-to-end. A selection of our work:
Live online abacus and mental-arithmetic classes for children aged 4–14 — with certified instructors, small batches, eight graded levels and a free trial.
A blended and online learning platform offering accredited foundation, undergraduate and postgraduate courses, with assignment-based assessment and routes to university progression for local and international students.
More to come
Additional products may be introduced in the future. We add new products only when we can build and support them to the same standard.
