What Life Forecast adds as an alternative
Projected goal date from daily weigh-ins
A straight trend through your last 30 calendar days of weigh-ins (at least 3 points) produces a projected goal date and weekly pace — an estimate, not a guarantee. See our methodology page for limits.
Voice and photo meal logging
Log meals by speaking or scanning a photo in the web app. Calorie and macro figures are AI estimates — verify when precision matters.
Garmin daily summaries
Optional Garmin Connect sync brings daily summaries such as steps, sleep, and heart rate into your account. The projected goal date itself uses weigh-ins only.
Daily AI coach in Telegram
Optional @weightlogtbot sends a daily plan and accepts weight logs in chat. Food photos are not handled in Telegram — use the web app for meal logging.
MCP for AI assistants
Supported assistants can log weight and read your forecast through our MCP server (documented in llms.txt on this site).
Choose Life Forecast if…
You need Android, Linux, or a desktop browser
We could not find an official Happy Scale build for Android or the web (checked the US App Store and happyscale.com). Life Forecast runs in the browser on those platforms.
You want food logging beside your weigh-ins
Voice and photo meal logging live in the Life Forecast web app. Happy Scale is weight-focused per its store description.
You use Garmin daily summaries
Life Forecast can sync Garmin Connect daily summaries. Happy Scale does not list Garmin integration.
You want a free web app with no paid tier
Life Forecast is free (price $0) with no subscription required to sign in. Happy Scale is free to download with optional paid upgrades.
Stay with Happy Scale if…
You are on iPhone or iPad and Happy Scale already fits
Happy Scale is mature and actively maintained (version 2026.8.1 on the US App Store as of October 22, 2026).
You want Apple Health as the hub
Happy Scale documents Apple Health import/export on happyscale.com and in its App Store listing. Life Forecast does not support Apple Health or Health Connect today.
You prefer a native iOS experience
Happy Scale is a dedicated iOS/iPadOS app with passcode protection and multiple profiles listed on happyscale.com — polish that a browser app may not match.
You only need weight trends — not food logging
Happy Scale focuses on the scale and trend math. Life Forecast adds food logging, Garmin summaries, Telegram coaching, and MCP access — more surface area if you want a minimal tracker.
