TriTab Calc vs RingMe AI

A three-tab calculator that lets you keep multiple calculations going at the same time. The A, B, and C tabs each work as an independent calculator. Switch between them without losing your current expression or result. Use A for the pre-tax price, B for the tax-inclusive total, and C for the discounted price—all without writing down intermediate numbers or clearing your work. One purchase unlocks everything. No ads, no in-app purchases, no subscriptions. ■ Three Independent Calculators Switch between A, B, and C with one tap. Each tab keeps its own expression and result, so you can work on three calculations in parallel. ■ Compare All Three See the total of all three tabs and the difference between the highest and lowest at a glance. ■ Tax In and Out Add tax with one tap, or work back from a tax-inclusive price to the pre-tax amount. Set any tax rate in Settings. ■ Split the Bill Enter a total and the number of people to get the amount per person, with optional rounding up. ■ History, Copy and Undo Each tab keeps its own history.

RingMe is a simple personal alert app that helps you remember what matters at the right moment. Instead of setting an alert based only on time, RingMe lets you give each alert a reason — such as making a call, leaving for an appointment, taking a break, or anything else you want to remember. HOW IT WORKS • Choose or create what you want to remember. • Use IN to set an alert after a chosen amount of time. • Use AT to schedule an alert for a specific date and time. • Keep multiple alerts active at the same time. • See upcoming alerts and their countdowns in one place. • Cancel individual alerts whenever you want. • When an alert is triggered, choose DONE or REMIND ME AGAIN. • With REMIND ME AGAIN, choose a new delay and set the alert again. RingMe is designed to be quick and focused, without unnecessary complexity. No account is required. No subscription is required. RingMe does not rely on an external service to create your alerts.
