UK Calculator Pro covers UK personal finance calculations: PAYE income tax and National Insurance take-home pay, mortgage affordability and stamp duty, VAT add/remove, ISA and dividend tax, and student loan repayments for Plan 1, 2 and 4. Rates are updated for the current tax year.
Library Hours 24 focuses on library locations, study spaces and live opening hours with location-based search. Coverage is strongest in the UK and US metropolitan areas, and the database is expanding to additional regions.
PlayTools apps target Android 8.0 (Oreo) and newer. The games are optimized to run smoothly on mid-range and older hardware, and the utility apps are lightweight (under 30 MB installed).
Many PlayTools/CinderSpire tools run free in the browser with no install: a dice roller, D&D 5e encounter difficulty calculator, initiative tracker, character generator, fantasy name generator and dice probability calculator are all available on playtools.top.
