Timelines helps you make the best use of your time
Timelines is an iPhone app that lets you track your time visually on an interactive timeline. With the clear picture of where your time is going, you’ll be able to improve over time.
Create a timeline for each project or activity that you care about. Then use timers to keep track of what you’re doing. You can also add events retrospectively and adjust their times.
With Statistics mode and the interactive timeline, you can quickly scale from the big picture overview down to a single day.
Define daily, weekly, and monthly targets for your categories, and get rewarded for reaching them with confetti. 🎉
With Timelines for Apple Watch, you can control timers without pulling your phone out of your pocket.
With interactive bar chart, you can see how your time spending habits evolve over days, weeks, months, and beyond.
Follow your goals, statistics, individual categories, and tracking status right on your home screen.
Before adding chemicals, you need to know where your levels should sit. Testing your water twice a week is the best way to prevent algae blooms and cloudy water. Use the following chart as your primary reference for daily and weekly maintenance. Ideal Chemical Ranges Chart Free Chlorine: 1.0 – 3.0 ppm (keeps water sanitized)
To Lower Chlorine: Stop adding chlorine and let sunlight dissipate it naturally. To Raise pH: Add Soda Ash (Sodium Carbonate). To Lower pH: Add Muriatic Acid or Sodium Bisulfate. To Raise Alkalinity: Add Baking Soda (Sodium Bicarbonate). To Lower Alkalinity: Use Muriatic Acid. To Raise Calcium Hardness: Add Calcium Chloride.

pH Level: 7.4 – 7.6 (prevents eye irritation and equipment corrosion) Total Alkalinity: 80 – 120 ppm (buffers pH levels) Before adding chemicals, you need to know where
| Chemical Parameter | Ideal Range | What happens if it's LOW? | What happens if it's HIGH? | | :--- | :--- | :--- | :--- | | | 1.0 – 3.0 ppm | Algae growth, bacteria risk, cloudy water. | Strong "chlorine" smell, skin/eye irritation. | | pH Level | 7.4 – 7.6 | Eye irritation, corrosion of metal parts, etching of plaster. | Scale formation, cloudy water, chlorine becomes ineffective. | | Total Alkalinity (TA) | 80 – 120 ppm | "pH Bounce" (pH moves erratically), staining. | Cloudy water, scaling, stubborn pH that won't change. | | Cyanuric Acid (CYA) * | 30 – 50 ppm | Chlorine dissipates rapidly in sunlight. | "Chlorine Lock" (chlorine becomes ineffective). | | Calcium Hardness | 200 – 400 ppm | Etching of plaster, grout dissolution. | Scaling on tile/walls, rough surfaces. | Ideal Chemical Ranges Chart Free Chlorine: 1
You cannot dose a pool correctly if you don't know the volume. Use a pool volume calculator (Length x Width x Average Depth x Multiplier).
Calcium Hardness: 200 – 400 ppm (prevents plaster damage or scaling)
“I personally wasn’t happy about the way I was spending my time, which is one of the main reasons why I decided to build this app. Timelines has been helping me and other users be more aware of our time and use it more wisely. It is also my passion and I’m dedicated to it 100%. There are big plans for the future (read more in Press Kit). Have any questions or comments? and I’ll reply within 24 hours.”
