Paper, WhatsApp, or an app: an honest comparison for swim coaches
2026-07-04
Most clubs run their sessions with whatever's already at hand: a printed sheet, an Excel file, or a WhatsApp group to send out the evening's set. It works, up to a point. Here's where each method holds up and where it falls short, no sugarcoating.
Paper poolside
The oldest method, and it has a real advantage: nothing to load, nothing that crashes, readable even with wet hands. For a simple session with one level group, that's still plenty.
Where it breaks down is the moment a group mixes several levels. Writing out differentiated split times by hand, for every swimmer, for every block of the session, takes time few coaches have before an 18:00 session. In practice, plenty of coaches end up giving the whole group the same time, which trades personalization for speed.
Excel
Excel is the big leap forward from paper. Once the formulas are in place, times recalculate on their own for each swimmer based on their profile. Plenty of clubs have a homemade file that's remarkably well built, refined over years, with all the history in it. Yours might be one of them.
The trouble shows up over time. These files get fragile: a formula that breaks, an external link pointing to the wrong tab, a colleague touching a cell without knowing what sits behind it, and the workbook goes sideways without warning. You often notice too late. And on top of that, none of it reads well poolside: every change means reprinting.
WhatsApp has one real merit: everyone already has it on their phone, zero friction to send something out. But a WhatsApp message was never built to structure a swim session. A photo of the whiteboard, a set typed as free text with no formatting, no earlier version findable three weeks later when a swimmer asks "what did we do last week again?". It gets you through, it doesn't replace a real planning tool.
A dedicated tool
The idea behind a tool built for swimming is to keep what each method does best without dragging along its flaws. The simplicity of paper, but with the calculations done for you. The power of Excel, without the file that breaks. The convenience of WhatsApp on your phone, without the mess of a conversation where everything gets lost.
That's what SwimConsult rests on. You write the session in plain language, every swimmer gets their own times calculated from their profile, established with a V4 lactate test or a 30-minute field test, and you keep all of it readable and editable right there poolside. No file to reopen, no message to hunt down three screens up.
So which one should you pick
Honestly, it mostly comes down to how complex your groups are. If you coach a single even group and aren't trying to keep a history, paper still does the job just fine, no need to overcomplicate things. The moment you're juggling several levels in one lane and want tailored times, Excel gets hard to avoid, provided you accept the upkeep that comes with it.
The real tipping point is when you want the personalization of Excel, the simplicity of paper, and the mobile access of WhatsApp all at once, without spending your Sunday evenings maintaining a file. That's exactly where a dedicated tool starts earning its price.
