Head-to-head comparison
WhispCal vs Lifesum: Diet Plans or a Measured Target
Lifesum is a Swedish tracker with a big following in Europe. People pick it for the diet plans (keto, Mediterranean, 5:2, high protein), the food ratings and a calm, well-designed interface. If you want to be handed a plan, it does that well.
WhispCal does one thing Lifesum does not. It measures your real burn from what you log and weigh, then moves your calorie Target for you. Here is how the two compare.
| Feature | WhispCal | Lifesum |
|---|---|---|
| Diet plans | No, a measured Target instead | Yes, curated plans |
| Food ratings | No | Life Score |
| Voice logging | Yes, a few seconds | No |
| Metabolism measured | Yes, real burn from your data | No, formula estimate |
| Target adjusts itself | Autopilot | Only when you edit your profile |
| Price | Free / $4.99/mo | ~$8/mo* |
Plans versus a target that moves
Lifesum's diet plans are its real strength. Pick a plan, get a calorie goal, a macro split and recipes that fit it. The Life Score rates what you eat over the week. For someone who wants structure and gentle guidance, it is a pleasant place to be.
The goal itself comes from a formula and your profile. It moves when you update your weight or your plan, not on its own. WhispCal's Autopilot reads your weight and intake over a few days, reaches a Verdict, and moves your Target one step, with a Brief that says why. You confirm, postpone or overrule.
Logging speed
Lifesum logs by search, barcode and, on Premium, photo. The database is broad and the interface is quick for a search-first app.
WhispCal logs by voice, photo, barcode or text, and a meal is in within a few seconds. Hold a food and drag to fix a portion, no keyboard. Fewer taps per meal is what keeps the habit alive on busy days.

Metabolism and price
Lifesum does not measure your expenditure. Its goal is an estimate that stays put until you change your profile. WhispCal measures your real burn from your weight and meals, shows you how it drifts as your body adapts, and gives you a calorie range rather than one exact number.
At the time of writing Lifesum Premium is around $8 a month, cheaper on the yearly plan, and the free tier is limited. WhispCal is $4.99 a month, with a free tier that includes the measured burn and no ads. Both run on iOS and Android in English and French.
