A coaching app focused only on the maintenance phase after weight loss: weekly weigh-in ranges, reverse-diet plans, habit streaks.
The problem people are complaining about
On 2026-10-21, a thread titled “What have you been doing to maintain the weight you’ve lost?” reached #42 in our daily ranking of health problems on Reddit. In health, people most often struggle with symptoms people are unsure about, weight loss plateaus, fitness and when to see a doctor; this one stands out because the person asking has a concrete, repeatable need rather than a one-off emergency. When the same question keeps appearing in public, it usually means existing products either don't reach these people or don't answer the question in the way they need. That gap is what Maintain Mode aims at.
Who the customer is
People who recently reached a weight-loss goal and fear regaining it, now that diet apps built for losing weight no longer fit.
In short, the first customer to target is: People who just reached a weight-loss goal. Start with the narrowest version of this group you can reach directly, ideally in the same communities where the problem was posted, rather than trying to serve everyone with the problem at once.
The idea
Maintain Mode is a subscription app idea. A coaching app focused only on the maintenance phase after weight loss: weekly weigh-in ranges, reverse-diet plans, habit streaks. It makes money through $7/mo.

Pricing guess
Estimate: $7/month. This is our estimate, not market data: treat it as a starting hypothesis and test it with real buyers before relying on it. Price anchors from the alternatives below and what people already spend on workarounds are the best reality check.
MVP you can build
Month: weekly check-in bot with maintenance-calorie calculator. Keep the first version deliberately small: the goal is to learn whether people use it and pay, not to build every feature.
How to validate it in three steps
- Run a free 4-week maintenance email programme.
- Measure weekly check-in rates.
- Offer a paid month to finishers.
Decide your success threshold before you start each step (for example, a number of signups or pre-orders), so the result actually tells you something.
Competition & existing alternatives
MyFitnessPal, Noom, MacroFactor Before building, try each alternative as a customer would and note exactly where it fails the people in the threads; that gap is your positioning.
Risks
- Crowded fitness app market.
- Health claims must be careful.
- Retention after goals are met is hard.
How we scored it
Opportunity score (6/10) is an editorial judgement combining four factors: how strong and frequent the demand looks, whether the customer already spends money on the problem, how crowded the alternatives are, and how much effort the first version takes. Signal score (2/10) is calculated from our data only: 2 points for one thread, 4 for two, 6 for three or more; +1 for each extra day the problem appears (max +2); and +2 if it ranked in the daily top 10, +1 for top 25, +0.5 for top 50. Neither score is a forecast. See how it works.
