Ratings & Reviews
The AI calculator is here — and the money tools got a lot more useful.
AI Calculator (new)
Say it the way you'd say it out loud: "split 148.60 four ways with an 18% tip." You get the number, plus the steps that got you there.
Sales Tax
All 50 states plus city rates, and reverse math from a total when the receipt only shows the final price.
Tip & Split
Tip on the post-tax amount, split by however many people are at the table, and a round-up option when you just want a clean number.
Unit Price Compare
Enter the pack size, see the real price per ounce — the bigger box isn't always the better deal.
Savings & Compound Interest
Recurring deposits, an actual growth curve, and a balance you can read at a glance.
Also in this version
• Faster cold start and a more responsive keypad.
• Currency rates refresh properly again after the app has been in the background.
• Cleaner tool grid, larger tap targets, better contrast in dark mode.
Thanks for using the app. If it saves you a minute, a rating saves us a lot.
