Keeps adding features which is nice

### 5/5 — Great software

*2025-11-03*

Looking forward to more free updates

### 1/5 — very poor

*2018-09-03*

This app does NOT do what it claims to do on the app store, nothing remotely like it.  The developer offers lots of apps and
this looks and works like one of the others, Hours, minutes, seconds. It does Not do what it says on the app store.

### 5/5 — Very good app! Highly recommend!

*2017-03-22*

Used this app and its like date calculator of windows 7 where I have to input the dates and not scroll to find the specific date and year where I find it extremely annoying. Don't change the interface as I find it like this very useful at work.

### 5/5 — Just what I needed

*2016-04-29*

I'm using this for hh:mm:ss calculations for audio and video editing, very handy, works great.

### 5/5 — Works very well

*2015-06-27*

Helpful for getting time entries summations at work. Keeps getting better...

This is a Recommended App.

### 1/5 — Waste of time

*2013-02-10*

This app is a load of rubbish! Struggle to say much more. Only giving one star because it won't submit review otherwise.

### 4/5 — Works ok, but needs a few tweaks

*2012-11-17*

The interface for adding time (days/hour/mins/secs) is clear and works fine.  The Column (like a paper tape on an adding machine) is a nice touch.  The Date Difference feature, however, could use some improvement.  For date entry, instead of a number keypad, it brings up the standard keyboard, and, annoyingly, keeps reverting to the alphabetical keyboard, which necessitates way too many keystrokes to enter a simple date.  This needs to be improved.  But the app does the job it's intended to do.

### 7.4 — 2026-06-03

If you're the kind of pilot who notices the little things, checks the numbers again, and cares whether a tool feels dependable on a busy day, this update was built for you. This release tightens the app across planning, weather, and scheduling so common calculations feel quicker, clearer, and more consistent from one screen to the next.

What feels better right away:
- Cleaner movement between calculators.
- Better continuity between planning, weather, and duty tools.
- Less friction when you revise values quickly.
- Results that are easier to scan at a glance.
- A steadier feel when comparing one scenario against another.

Flight planning improvements:
- E6B workflows feel tighter when you're running heading, groundspeed, time, and fuel checks back to back.
- Wind, fuel burn, and true airspeed tools are easier to use in sequence.
- Density altitude and performance checks read more cleanly on repeat use.
- Weight and balance review is easier to follow when passenger, bag, or fuel numbers change.
- Time, speed, and distance math is quicker to verify during preflight planning.

Weather workflow improvements:
- METAR and TAF results are easier to scan when you only need the important answer fast.
- Decoded weather output reads more naturally and feels less crowded.
- Live weather checks fit better into the rest of the app instead of feeling separate.
- NOTAM review is easier to sort when you are deciding what matters operationally.
- SNOWTAM decoding remains ready for winter ops and unusual runway-condition checks.

Scheduling and time-tool improvements:
- Countdown planning is more useful when you need a clear backward plan from a report time, event, or deadline.
- Business-day calculations are easier to trust for planning around real work windows.
- Duty and block-time review is cleaner after long days with several moving parts.
- Date and time utilities are easier to move through when checking several scenarios in a row.
- Related planning tools now feel more consistent as a group.

Input and readability refinements:
- Better spacing around key result groups.
- Clearer separation between entry areas and answers.
- Less clutter on screens that carry a lot of information.
- Improved field flow when entering and revising values.
- Better rhythm when you clear a number, replace it, and move on.

Everyday use improvements pilots will notice:
- Quicker ramp checks when a wind, fuel, or loading number changes.
- Smoother lesson use when a student asks for one more scenario.
- Faster cross-checks when comparing a manual answer against the app.
- Cleaner handoff from preflight planning into records or duty review.
- Less second-guessing about where to look first on each screen.

This release also improves the overall tone of the app. The calculators feel more closely related, the layout feels more settled, and the answers are presented with less visual noise. That matters when you're trying to make a sensible check between other tasks instead of sitting down for a long session with no interruptions.

Why this update matters:
- It saves time on the small checks that add up during a flying day.
- It reduces the friction between question and answer.
- It makes repeated planning work less annoying.
- It helps the app feel dependable instead of merely feature-heavy.

You may notice the difference most when:
- Rechecking wind and fuel after an updated weather briefing.
- Running another loading scenario before departure.
- Comparing two timing options for a report or duty window.
- Cleaning up numbers after a long day and wanting the app to stay organized.

Thanks for using Flight Calcs the way good pilots use tools: carefully, repeatedly, and with enough attention to notice rough edges. That use keeps shaping the app into something more useful in real flying.

### 7.3 — 2026-05-30

The E6B calculator, METAR decoder, weight and balance calculator, and NOTAM decoder all got meaningful attention.

METAR AND TAF DECODER:
METAR parsing is more reliable now across a broader range of station formats. The previous version stumbled on a few real-world patterns,  non-standard ceiling group spacing, TEMPO and BECMG change groups that crossed midnight, and some CAVOK reports that weren't producing the correct IFR/VFR/MVFR/LIFR category. All three are fixed. The TAF decoder display was also reworked: forecast periods that used to stack together in a way that made the timeline hard to read now show as clean, distinct rows with explicit validity windows. If you regularly decode TAFs for IFR flight planning or preflight weather review, it should be more usable now.

NOTAM DECODER:
The subject classifier that categorizes NOTAMs by type,  airspace, obstacle, ILS, runway, navaid, and so on,  now catches a wider range of text patterns. More NOTAMs come back with a useful label instead of hitting the generic fallback. The affected airport extraction logic was also updated to handle NOTAMs where the relevant airport appears in the body text rather than just the header identifier. Summary output is tighter and more to the point, particularly for NOTAMs with long agency preambles before the actual operational content.

WEIGHT AND BALANCE CALCULATOR:
The CG envelope check now handles aircraft profiles where the forward and aft limit lines aren't linear across the full weight range. If your POH envelope has a stepped limit or a curve that changes slope at a particular weight, the within-limits check respects that shape instead of approximating it as a straight line between endpoints. The per-station loading breakdown is also easier to read,  totals align consistently, and the layout holds up better when you have five or more stations loaded.

HOLDING PATTERN CALCULATOR:
Direct, parallel, and teardrop entry recommendations are now calculated against tighter sector boundaries. There was a small angular bias in the previous version that occasionally pushed a boundary case,  typically right around the 70-degree or 110-degree lines,  into the wrong entry type. That's corrected. The result view now also shows the inbound course alongside the recommended entry heading, so you can cross-check against the approach plate without doing extra mental math.

E6B CALCULATOR AND WIND TOOLS:
Wind correction angle output now shows the aircraft's max demonstrated crosswind component as a reference when you have a profile loaded. Useful when you're working a gusty crosswind scenario and want to know where your computed crosswind sits relative to the aircraft limitation. The true airspeed calculator was also corrected for sub-zero OAT inputs at high altitude,  cold soak conditions were producing TAS values that ran slightly high, and that's been fixed.

PILOT TIME AND FLIGHT DUTY:
The flight duty snapshot screen handles long-day entries more cleanly now. Block time accumulation across multiple legs renders more consistently, and the shareable text output was reformatted to be less cluttered when the duty period has more than four segments. Shift rounding calculations with split-day scenarios,  overnight duty that starts on one date and ends on the next,  now resolve the date boundary correctly.

INPUT BEHAVIOR:
Rapid field edits,  clearing a value and typing a replacement quickly,  were causing some calculators to lock up and stop updating until you tapped somewhere else. Fixed. The keyboard done button now always triggers a recalculation immediately on dismiss, across all calculators. The previous behavior, where it sometimes took a second tap to get the result to update, is gone.

Keep the bug reports and feedback coming. This update is largely built from real-world notes sent in by pilots who caught things that weren't working the way they should.
