TAB66

TAB66 is a utility app whose percentage calculator is complete in every sense, four separate modes cover every direction a percentage problem can go, delivering results the moment you enter your values. The four modes are designed so you never have to rearrange a formula yourself: TAB66 handles the arithmetic while you just pick the mode that matches your question and fill in the numbers you already have. From finding a percentage of a value, to determining a ratio as a percent, to applying increases and decreases, to reverse-calculating original values, the full set of practical percentage problems is covered in one clean tool. The metronome offers a completely different kind of precision in the same app: set a tempo from 20 to 300 BPM, tap to detect your rhythm, choose your time signature (2/4, 3/4, 4/4, or 6/8), and practice with a visual pulse or silent vibration. TAB66 requires no internet and no account, all 10 tools including all four percentage modes are available instantly and offline.
