Perim vs Balance vs Clue vs Flo: Perimenopause Apps Compared (2026)

Four Apps, Four Different Jobs

Perim, Balance, Clue, and Flo all track perimenopause, but they come from different places: Perim and Balance are purpose-built for the menopause transition, while Clue and Flo are broad cycle apps that added dedicated perimenopause modes. That origin shapes what each does best. Flag Apps develops Perim, so this comparison applies the same criteria to all four — privacy, price, platform, symptom depth, and best fit — checked against official pages on August 19, 2026.

At a Glance

• Perim: iPhone; on-device by default, no account; symptoms plus calorie and macro tracking; best for privacy and speed.
• Balance: iOS and Android; account required; free symptom charts, questionnaire, education, and a health report; best for free reports and learning.
• Clue: iOS and Android; cloud account; adaptive perimenopause mode in Clue Plus; best for existing cycle history.
• Flo: iOS and Android; cloud account; broad tracking with premium perimenopause tools; best for current Flo users.

Privacy

This is the clearest split. Perim keeps health-adjacent entries on the device by default, with no account and no advertising trackers. Balance's terms state an account is required, and Clue and Flo are cloud-based services. None of that makes the cloud apps unsafe, but if minimizing your data footprint is the priority, an on-device model exposes the least.

Price and Free Features

Balance stands out for free features: its terms list symptom and mood charts, a questionnaire, a period calendar, education, and a health report among free services. Clue's perimenopause mode requires Clue Plus, and Flo's perimenopause tools are Flo Premium features. Perim offers free logging; check its current App Store listing for any paid tier.

Symptom Depth and Extras

All four cover the core perimenopause symptoms — cycle changes, hot flashes, sleep, and mood. Balance adds the most education and a formal report; Clue and Flo bring broad cycle histories and predictions; Perim adds built-in calorie and macro tracking and guided movement, so food, exercise, and symptoms live in one app. The ACOG Menopause Symptom Tracker is a good yardstick for whether an app covers what matters.

Who Each One Is For

• Choose Perim if you want privacy, speed, and food-plus-symptom tracking on iPhone.
• Choose Balance if you want the most free education and a shareable health report.
• Choose Clue if you already have Clue cycle history and want an adaptive mode.
• Choose Flo if you already use Flo and want to keep everything in one broad app.

The Shared Limit

None of these apps diagnoses perimenopause or measures hormones — each organizes symptoms for a clinical conversation, and the NHS notes the diagnosis is usually made from age, symptoms, and menstrual history.
