■ 今日のラウンドサマリー

スコア 92(OUT 47 / IN 45)。後半はあなたの持ち味であるパットの距離感(平均1.7)が冴えて、流れを立て直せた1日です。崩れたのはOUT5番のトリプルだけ——ここを除けば、いつものあなたの安定したリズムどおりでした。

■ 今日のコンディション

曇りで、風は中くらい。あなたは後半に伸ばすスロースタータータイプで、今日も前半は硬さが残ったまま終えています。前半47は技術の崩れではなく、いつもの入り方による数打分。得意のミドルアイアンは今日も安定していて、いつもどおりの仕上がりです。

Our changelog is public. Read our golf analysis and improvement articles too.

  1. Added a CSV import check and fixed round entry issues

    • ImprovedCSV imports now let you review rounds with a hole count other than 9 or 18 before saving

    • ImprovedLimited the wait for popular blog posts when view counts take too long to load
    • FixedApplied security fixes to the libraries the app relies on
  2. Removed the temperature field and added the day's weather to each round

    • ImprovedRemoved the temperature field from round entry and editing (people entered it at different times of day, so the values could not be compared)
    • NewEach round now shows the day's weather, rain, wind and temperature during play, and rounds without a weather record let you record it right there
    • ImprovedThe round list now shows a rain icon for rounds without a weather record when weather data for the area shows rain
    • ImprovedThe AI caddie now takes your temperature trend into account when your scores clearly differ by temperature
  3. Auto-filled weather shows its source, and Conditions and Course Analysis show more of your stats

    • ImprovedWhen round entry fills in the weather automatically, one line now shows that it comes from WeatherAPI.com and is only a guide
    • ImprovedRounds now save whether you kept the auto-filled weather or chose it yourself
    • NewWeather Impact is now Conditions, where you can compare putts, greens in regulation and more by weather, wind and the day's temperature, wind speed and rain

    • NewCourse Analysis now shows your results by green count, turf and terrain, and for each course (East, West, South and so on) of a 27+ hole facility
    • ImprovedCourse Notes no longer mix up holes from back-nine starts or 27-hole rotations, and each hole now shows how your scores spread (with Premium, also during round entry)
    • ImprovedOn the end-of-round screen, View AI review now saves the round, opens its page and creates the AI round review there and then
    • NewThe AI caddie now has Ask the AI caddie, with questions picked from your records that it answers from your own numbers when you tap one (the questions are picked again each time you save a round)
    • ImprovedThe AI round review and the AI caddie now also read the details you record, such as clubs and approach results
    • NewRound entry can now record whether a bunker was greenside or in the fairway, and whether you got up and down from a greenside bunker within 2 shots (you can also record your pre-round warm-up)
    • NewShort Game Analysis now shows your sand save rate next to a benchmark for golfers who score about the same, and Front/Back Analysis shows how your opening holes go by warm-up
    • ImprovedCSV export now includes every item you record, and importing the file again brings everything back as it was
  4. Reworked how records are handled and what comments compare you to, and course notes now sync

    • ImprovedFile import and photo reading now save missing weather, wind, OB and similar items as not recorded instead of filling in placeholder values
    • ImprovedAverages and weather breakdowns no longer count items that weren't recorded
    • NewCourse notes are saved to the cloud, so you see the same notes on your phone and your PC
    • ImprovedWhen editing a round, you can now fix the course type, temperature, green speed, play style and the front and back nines

    • NewThe Strokes Gained page now shows what to work on next
    • FixedFixed analysis comments sometimes not showing under a chart because other comments crowded them out

    • NewPar 3 tee-shot results are now broken down by club and compared with the carry you registered for that club and the hole length
    • NewTee Shot Analysis now shows results by tee club and how many strokes one OB or penalty actually cost you
    • FixedThe comment, the Next move card and Today's Discovery now agree on whether your tee-shot misses lean left or right
    • NewPutting Analysis now shows your putts after reaching the green, split by whether you got there in regulation, one shot later (bogey-on) or later than that
    • NewShort Game Analysis now breaks down how you make par and shows how often you make par or better after reaching NTG
    • NewApproach misses are now tallied by direction, including how they differ by pin position
