Here’s how Zero helps you get there: • Track your intermittent fasting — Engage timers, streaks, and insights keep you stay motivated and consistent across your entire fasting journey. • Log meals the smart way — Skip the tedious manual meal entry routine.

Your first meal logs are on us, so you can try it before you subscribe. • Hit your Protein Score — Zero Plus tracks a personalized daily protein target that adapts to your weight and goals. Better protein = better satiety, better muscle retention, better weight loss. Zero makes it automatic. • Complete the equation: Fasting + Protein — Most people fast or track meals. Zero brings them together so you lose weight, protect muscle, and avoid the pressure and guilt of traditional calorie trackers. • Stay hydrated to power your fasts — Water tracking with Zero Plus helps you maintain energy, reduce cravings, and support metabolic function throughout the day. • Build healthy habits that actually matter — Track movement, sleep, mood, and other daily pillars that reinforce your fasting and fueling routine. • Challenge yourself — Hit protein targets, maintain fasting streaks, and stay accountable with motivating challenges built around outcomes, not vanity metrics. • Learn the real science — Understand how fasting, protein, and hydration work together for sustainable weight loss and metabolic health — with insights from leading experts. • See measurable progress — Watch your streaks grow, your protein consistency rise, and your body composition improve with clean, insightful trend views.

Verdict
The clearest difference is rating: Zero at 4.8 against Colour Widgets's 4.2. Zero also leads on ratings volume (445K vs 33) and chart position (#116 vs unranked). Colour Widgets's advantage is in-app purchases (none vs 17) and update cadence (every 2 days vs every 2 weeks). On price, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Zero sells 10 in-app purchases, starting at $9.99 per month. Colour Widgets asks for nothing beyond the download.
Zero holds the better App Store score, 4.8 against 4.2. That said, the two scores are not equally well evidenced: Zero has 445K ratings behind it against 33, so its average is the more settled of the two. Written reviews complicate that: 32% of Zero's written reviews are positive against 50% of Colour Widgets's, so the app with the better star average is not the one people write more warmly about.
Zero ships an update every 2 weeks, Colour Widgets every 2 days. The most recent releases landed on October 30, 2026 and October 25, 2026 respectively.
