Senza is a long-running free keto tracker that pairs macro tracking with educational content and recipes. Keto Kit is a newer keto-first app with a built-in 5-stage fasting timer, a daily 0–100 Keto Score, gamification, and a Premium tier that adds a keto-trained AI coach plus AI logging. Both target keto users specifically and both have free tiers — the question is which design and feature mix fits your daily flow.
Bottom line
Senza is a solid free keto tracker with a strong educational layer and a keto recipe library. Keto Kit's free tier adds a daily Keto Score, 5-stage fasting timer, and gamification that Senza doesn't offer at any tier. Both are credible keto-specific options; Keto Kit has the more comprehensive free tier and a Premium AI coach for users who want guidance on demand.
Last reviewed: April 2026
Choose Keto Kit if you want a free tier with daily ketosis signal (Keto Score), integrated metabolic-stage fasting, gamified habit reinforcement, and an optional Premium AI coach for keto questions. Premium ($5.99/month) adds AI photo and voice logging plus the AI coach.
Choose Senza if you prefer an education-first approach with keto lessons and articles inline, like Senza's recipe library and existing community, and don't need daily ketosis scoring or 5-stage fasting tracking.

Going beyond the feature-checklist view — the substantive differences in how each app handles the things keto dieters actually use day-to-day.
Keto Kit
Keto Kit ships a daily 0–100 Keto Score combining net carbs, macro ratios, hydration, and logging consistency. It's the centerpiece of the dashboard and gives a single-glance answer to 'how was today for keto?' — included on the free tier.
Senza
Senza has no equivalent to the Keto Score. Users monitor their own macros and infer ketosis adherence by reading the numbers themselves.
Keto Kit
Built-in fasting timer with five metabolic stages (Fed, Transition, Fat Burn, Ketosis, Autophagy). Presets for 12:12, 16:8, 18:6, 20:4, OMAD, plus custom windows — included free. Live progress through stages keeps fasting visible alongside macros.
Senza
Senza added a basic fasting timer in recent versions. It tracks elapsed time and basic stages but doesn't deliver the same metabolic-stage depth as Keto Kit.
Keto Kit
Keto Kit's Keto Academy ships 30+ illustrated lessons covering ketosis, electrolytes, fat adaptation, and plateaus — gated to Premium. Free users get a smaller library of articles and the public Keto 101 glossary on the website.
Senza
Senza pioneered the inline-lesson approach in keto apps and ships a strong library of articles for beginners on the free tier. If education-as-you-go is the priority, Senza's free content layer remains a real advantage.
Keto Kit
Premium ($5.99/month) includes AI photo recognition for instant dish/portion analysis, natural-language voice logging, and the keto-trained AI coach — backed by your actual macro context.
Senza
Senza has no AI photo recognition, voice logging, or AI coach at any tier.

A practical checklist for moving your data, habits, and baseline tracking over without losing momentum.
Note your current Senza macro targets before switching.
Re-enter them in Keto Kit (or use the in-app Keto Calculator if you want to recompute from scratch).
Re-add your most-frequent foods to Keto Kit's quick-add list during the first week to keep logging fast.
Enable Apple Health or Google Fit sync if you used Senza's health-app integration.
Run both apps for a few days if you want to verify daily totals match before committing.
Common questions about choosing between Keto Kit and Senza.
Senza continues to receive updates, though release cadence has been slower than newer keto apps. For current users it's still a competent free tracker; whether to switch depends on whether the keto-specific features Keto Kit adds (Keto Score, 5-stage fasting, AI coach) are valuable to your workflow.
No. Senza shows your macros and lets you interpret them yourself. Keto Kit's daily 0–100 Keto Score combines net carbs, macro ratios, hydration, and consistency into a single signal — included on the free tier.
Yes — Senza added a basic fasting timer in recent versions. It tracks elapsed time but doesn't track metabolic stages with the depth that Keto Kit's free 5-stage timer provides.
Senza Premium is a light tier (mainly ad removal and bonus content). Keto Kit Premium ($5.99/month) adds substantial features: AI Photo Scan, Voice Food Logging, the Keto AI Coach, full recipe library access, AI meal planning, and batch barcode scanning. The two Premium tiers aren't comparable in scope.
Both ship keto-curated recipe libraries. Keto Kit's library is 1,000+ recipes with verified macros, organized for the in-app Cooking Mode (hands-free step navigation). Senza's recipe library is smaller but well-loved by its existing user base. Per-recipe quality is comparable; library size and Cooking Mode favor Keto Kit.
You can, but most users find one app sufficient once they've consolidated. The duplication of macro logging across two apps tends to outweigh the marginal benefit of Senza's lessons (which Keto Kit's website Keto 101 also covers, free).
Both are genuine keto-specific apps with free tiers. Senza's strength is its inline educational content and longstanding keto community. Keto Kit's strengths are the daily Keto Score, 5-stage metabolic fasting timer, gamification, and a keto-trained AI coach on Premium. For users who want the most daily signal on keto, Keto Kit's free tier covers more ground. For users prioritizing education-as-you-go, Senza's free lesson library remains a real advantage.
