The Pro QC AQL (Acceptance Quality Limit) calculator (based on based upon ANSI Z1.4-2003) makes it easy to determine a sample size and the proper number of allowable rejects in a particular shipping lot size. It is a fundamental tool for preparing a sampling plan for a random product inspection as it allows to set the number of samples to inspect, and the maximum numbers of defects that is allowed. This free application takes the place of the traditional paper card that many inspectors in the field use.

TimeCalc is a powerful yet simple time calculator for everyday use — add and subtract hours, track work durations, calculate future dates, and find exact age in seconds. TIME CALCULATOR Add, subtract multiple time values in sequence. Instant results, calculation history saved. Examples: 2h 35m + 3h 45m = 6h 20m 12h 20m − 4.5h = 7h 50m 4h 52m × 3 = 14h 36m 1h ÷ 20m = 3 Convert between time units: 456m = 7h 36m = 7.6h TIME BETWEEN (DURATION) Enter any start and end time to calculate the exact duration. Organize into separate categories. Export PDF reports (Premium). Examples: 11:20 AM → 12:40 PM = 1h 20m 01:30 AM → 02:30 PM = 13h Today 02:00 → Tomorrow 02:30 = 24h 30m DATE CALCULATOR (ADD & SUBTRACT) From any starting date, add or subtract years/months/weeks/days/hours/minutes to get the resulting date. Calendar-accurate arithmetic — adding 1 month to Jan 31 gives the correct last day of February. Example: Today 17:32 + (1d 2h) = Tomorrow 19:32 AGE CALCULATOR Calculate exact age in years, months, and days from a birth date.

Verdict
The clearest difference is rating: TimeCalc at 4.5 against AQL's 3.3. TimeCalc also leads on update cadence (every 5 weeks vs every 19 months) and review sentiment (79% vs 50%). AQL's advantage is in-app purchases (none vs 4) and ads (none vs shown). On price and device support there is nothing between them.
