    FWIW: Your initial proposition, "Your days are slipping away." is a negative framing. Maybe this is a good way of appealing to people's fears, but I thought it was depressing and was not eager to read more.

    An alternative could be something like "Make the most of your days".

    • By watwut 2025-09-2714:13

      I think that I have heard or read "Make the most of your days" in various ads and inspirational motivators too many times. It is something that makes me ignore whoever is saying it, because it was overused by everyone else.

    • By maghfoor 2025-09-2713:423 reply

      Dude, that is so true. I think I agree with you and your reframing. Going to change it to that

      • By maghfoor 2025-09-2713:441 reply

        And just like that, changed it in under 1min. Beauty of web dev.

        • By bdangubic 2025-09-2714:211 reply

          you should reconsider, make the most if your days sounds like new years resolution that will end by the time you run of of ham

          • By iammjm 2025-09-2714:291 reply

            I think your comment is more a statement about you and your past experiences, because I vibe with "make the most of your days" in a positive way

            • By Dilettante_ 2025-09-2716:182 reply

              Sounds like soulless generic ad copy that you see everywhere to me(respectfully, that's just how I read it).

              • By mhb 2025-09-2813:59

                That's fine. I'm not saying that particular example was great. Just that it might be better to have a positive rather than a negative "vibe".

              • By bdangubic 2025-09-283:39

                carpe diem eh? never heard that before :)

      • By iglio 2025-09-2819:49

        You could consider running an A/B experiment, and track which treatment users engage with most.

      • By integralid 2025-09-2717:48

        I actually think about my life slipping away almost daily, but the reframing works too.

        It's a dark pattern. Would you also call it "sensitive" to want to be able to cancel a subscription without going through 3 pages, filling out a form, and convincing a call center worker?

        • By chickenzzzzu 2025-09-2715:23

          i am a bit confused as to how a one click subscription cancelation is related to... what i am assuming you are desiring is... "non coercive marketing copy"?

    APP NAME - Three Cells: Your Life System

    Some history: A couple of days ago my app finally got approved and released on app store.

    Overall really happy with the release. Now I finally have something that I use every single day. Whereas previously I was using various different apps to journal, track habits, track my weight and manage tasks etc. Now I have all of that in one place.

    Initially it was a website that I built for myself but I realised that something like this is better built in an app after speaking with lots of people.

    I used Convex dev for my backend and that honestly made the backend part of creating this part very easy because I could just use the same structure I had for the web app. Convex was my choice because even for a website I wanted the data to always be in sync whether I access it on my phone or laptop.

    The most annoying part about building an app is having to go through the review process of app store. For a website, I can just make a change and it can be live in less than a minute. But the app store review process alone took me 2 weeks to release this.

    Using AI made migrating the website into an app really easy. I had some components like heat-maps and graphs which would have been really difficult to migrate over if I was doing this a couple of years back.

    The idea itself actually came from reading lots of productivity books and then stumbling upon an interview from Jim Collins who talks about how he tracks his own life and makes sure it's going in a direction that he wants

      Impressive work for a solo effort.

      Would love to see less front loading on the registration side - I fell off onboarding because I couldn’t get through the 12(!) page questionnaire.

      The value proposition is clear, just let me use the app. Notes (my current solution for this) doesn’t make me read summaries of other people’s research every time I open the app :-)

      • By iammjm 2025-09-2714:381 reply

        I agree. And I dont understand how this isn't a universal rule for all of software: let the user use the thing ASAP. Just let me fucking play with it instead of forcing me to read intros, watch videos, click through a tutorial, etc. Just let me explore and interact! And only then also offer me some guidance that I can jump in and out of.

        • By thefourthchime 2025-09-2714:42

          I couldn't agree more, for any apps I make I try to make the on boarding zero

      • By joshuanapoli 2025-09-2713:50

        Yeah, maybe it would be nice to have a fast-track onboarding option for common goals: lose weight, finish homework or chores, etc.

      • By maghfoor 2025-09-2714:08

        Thanks for the feedback, I will implement something to skip onboarding maybe for users who clearly understand the value proposition

    • By pmcarlton 2025-09-2713:281 reply

      Does your app have a name?

      • By maghfoor 2025-09-2713:33

        Yeah, it's called Three Cells: Your Life System on Appstore

  • By aaronsnow 2025-09-2714:182 reply

    Congrats, maghfoor. But the lack of price transparency is a real turn-off. Nothing on the website or in the App Store — you have to download the app to find out how much it will cost you.

    • By j_bum 2025-09-2714:343 reply

      For what it’s worth, in the iOS App Store, you can scroll down to look at the “In-App Purchases” drop down menu, and all of the prices are shown there.

      This is true for every app with IAP. It’s how I typically decide if I’ll download an app with IAP.

      • By crazygringo 2025-09-2714:491 reply

        That's helpful, thank you.

        But I'm not even going to bother looking if an app can't clearly advertise its price.

        It just feels like a dark pattern, like they're intentionally trying to trick me from the very start.

        Maybe the price will turn out to be fine, but it's sure not building trust from the start.

        • By buzzerbetrayed 2025-09-2715:282 reply

          That is the standard way to advertise your price in the App Store. What is more transparent than.. clearly posting your price?

          • By crazygringo 2025-09-2715:46

            I'm talking about the website that has been posted.

          • By arcfour 2025-09-2718:37

            Making the app cost X amount makes it immediately obvious how much it costs. IAP do not share this, even if they are posted publicly off in some corner.

      • By aaronsnow 2025-09-2716:00

        Wild. I've been using iPhones for 17 years and it took until today for me to learn this. Thanks j_bum.

      • By rplnt 2025-09-2718:20

        There is no free option, so hiding it under IAPs is kinda shady too.

    • By dexterdog 2025-09-2714:592 reply

      So how much is it for those of us non iOS people?

      • By zamadatix 2025-09-2715:161 reply

        Anyone should be able to view it, even without an Apple account: https://apps.apple.com/us/app/three-cells-your-life-system/i... (bottom right):

        > Three Cells Weekly $2.99

        > Lifetime Access to Three Cells $29.99

        > Three Cells Weekly $2.99

        The ratio here feels a bit off, $155.48/y or $29.99 for life screams "trying to push you to pay a lot for an app I know you won't stick with" rather than "we've got great value options for any type of user". There is a 7 day trial as well, so even more confusing as to which kind of user is supposed to want the weekly payment.

        • By WA 2025-09-2716:071 reply

          Insanely expensive weekly subscriptions are the new (scammy) meta in B2C apps. I find it off-putting as well.

          • By wildzzz 2025-09-2717:34

            People are just hoping they can skip from "hobby project" all the way to a project that funds a couple salaries just by overcharging for subscriptions. Apps that are meant to cater towards unorganized people are the worst for this because they know you won't stick with it. A week trial is just short of how long you'll likely use it before you forget or realize it's not working for you.

      • By conductr 2025-09-2715:051 reply

        My guess is it’s unavailable since it’s an iOS app

        • By dexterdog 2025-09-2719:02

          I meant how much is it since I can't install it to find out
