Show HN: I Made the Hardest Focus App

https://apps.apple.com/us/app/pocket-the-hardest-focus-app/id6746587044
41•Dhikshith12•4h ago
my phone secretly robbed all my dreams and i didn’t even knew it got so bad. when i saw my screen time being about 11hrs with ~95 phone pickups per day, i realized how bad it got.

my problem is that i could not avoid social media entirely as i post actively because i’m involved in marketing and branding.

I tried the usual, app blockers & time limits, but i always find myself hitting “one more minute” like a junkie.

i’m not looking for a complete social media absence or deleting everything as these radical solutions don’t fit my lifestyle and needs and i tend to come back needing even more.

the ideal solution for me would be that when i decided to focus on something for specified time i SHOULDN’T reach out to my phone instinctively and needed a wrist slap every time i did so.

three weeks later i put out the first version of the @hardestfocusapp - it’s built on a simple, physical truth: to focus, you must disengage.

the core mechanic of the app is a commitment device.

focus starts not with a button tap, but with a physical act of disengagement with the phone itself that adapts to any situation:

- keep it face down on a desk for deep work.

- put in the pocket while walking or commuting.

- lock the phone for long and uninterrupted focus.

this makes the act of disengagement itself as a trigger for start of focus.

the consequence is just as real.

picking up the phone triggers a 5-second warning siren duel.

failure to put it back will erase all the progress made, using the concept of Loss Aversion - a powerful motivator that makes the fear of losing progress more compelling than any virtual reward.

it’s not just an app blocker, it became my phone blocker.

now when i’m focusing, i’m not on my phone every other minute trying to escape from the thought I could not confront, the warning siren is so loud, it feels like a slap on the wrist and i immediately put the phone away.

now i’m not just running away from the thoughts, I’m confronting them and planning ahead

sadly my distraction is device-agnostic, so if my phone gets blocked I can just go for my laptop, PC or tablet
ahmedfromtunis•2h ago
On my phone, I use Samsung's wellbeing apps to limit how much time I can spend on the social apps. I succeeded in reducing the waste to less than 2 hours per day.

On my laptop, I block undesirable websites using `/etc/hosts`. This creates friction and my lazy ass bails out most of the time from pursuing the desire to check on instagram.

On my tablet, none of the social media apps are installed.

These of course aren't bulletproof solutions but I think a little of willpower is necessary for any solution to really work.

awongh•2h ago
This link should be to the website instead which seems to be a demo of the app.

It’s a good concept, I just installed dumbify, i’ll see how that goes first.

It seems like there is a lifetime option? The pricing doesn’t seem to indicate that. I don’t think I’d pay monthly for this limited set of features.

The written description in the App Store is gold. (Not the words in the screenshots… I’m talking about the long description, you have to scroll and look for it.

Everyone should read it. Anyone skimming this, take note. This dude’s app description in the app store absolutely wins the internet for today.

Advice to the developer, in the screenshots the concept is a bit vague. If you could somehow get a hook into the screenshots that leads people to read the full description (not an automatic action for most people) that would help a lot.

Waterluvian•2h ago
Gee you weren’t lying.

“…profits from your failure by selling you toys instead of tools” is rather profound to think about.

I like it but I need it for Android? Any chance of releasing it there?
nelox•2h ago
Right now the app leans heavily on punishment mechanics (loss aversion + alarms), which is super clever and already works better than the usual “one more minute” blockers. But there’s a whole toolbox of behavioral science that could take it further. Things like if–then planning (pre-deciding what you’ll do when the urge hits), shaping (starting with smaller blocks and leveling up), social accountability, or even sprinkling in variable rewards so it’s not only fear-driven. Add a bit of mindfulness at the start of each session, and suddenly you’re not just fighting your phone, you’re actually training focus like a muscle. That’s how you make it stick long-term.
busymom0•2h ago
For me, I connected needing to use addictive apps with exercising because that way, I would get at least some positive out of using addictive apps plus be time limited. My Run For Fun app lets you restrict apps until you exercise:

Redster•2h ago
Obviously, pre-deciding might not need an app, but with the other aspects of a good focus plan, are there good apps/plans/programs that you recommend to help with focusing and positive feedback and building focus muscle?
CharlesW•1h ago
> Right now the app leans heavily on punishment mechanics (loss aversion + alarms)…

For those who know the "tough love" approach won't be effective for them or their family members, I recommend checking out the gentler, less-aggressive approach of an iOS/Android app at the top of Apple's charts right: Hank Green's "Focus Friend". https://www.yourfocusfriend.com/

Hank Green from the Green brothers just made a focus app (and it’s free & cute with some purely aesthetical IAP)

Side note, but does anyone else have this thought process when faced with yearly subscription vs lifetime purchase?

1. If I buy a subscription and end up not using it, I've wasted money. 2. If I buy a subscription and end up using it, that means I should have just bought the lifetime purchase. So now I've wasted money. 3. If I buy a lifetime purchase and end up not using it, I've wasted money. 4. I don't want to waste money. I'll find a free alternative or build my own. 5. Exit app store, no sub or purchase made.

Talk about loss aversion...

tom1337•2h ago
Thats why I like Rent-To-Own. Splice (a software for virtual instruments, music samples etc) supports this a lot and I've used it a lot. 150€ for a VST upfront is hard but if I can pay 10x15€ instalments and pause / cancel them anytime before, I have no risk if I never really use the instrument. If I otherwise use it the supplier gets their full price and I get to own the product because at the tenth instalment you get a lifetime product key.
coldstartops•2h ago
I usually hand-wave reduce this problem to the "Ski Renting Problem", so in the worst case I pay twice the price of the lifetime purchase.
andy99•2h ago
I would group that kind of pricing with dark patterns, and I tend not no but anything when I see that. It's like designing the free shipping threshold to be a couple of dollars short of common purchases, buy 1 get the second for $5, etc. They all apply fake pressure hoping to upsell. I want a far exchange of money for goods/services, not a trick and if I feel I'm being tricked I leave.
SoftwareMaven•1h ago
While I agree with you almost universally, I think in this case, the pricing is meant to be part of the loss aversion technique the creator is employing.

My problem is there is no such thing as a lifetime subscription anymore. More like "until the company gets acquired and the new parent company gets bored or until I get bored, whichever comes first".

ChrisMarshallNY•1h ago
I’ve found most “lifetime” subscriptions are actually just a couple of years. The standard way to cut them off, is deprecate the app, and come out with a new one, with a different bundle ID.
zdc1•1h ago
It's another version of how gym memberships get you. Everyone errs on the side of over-committment and they get to make more money.

I've found I'm better off paying extra for a shorter duration until I've validated that I'll be using my subscription in 3/6/12 months from now. E.g. recently with Duolingo I ended up only paying for it on a monthly rate for about 4 months, and that wasn't even because I'd quit learning, I'd just found a much better app.

ahmedfromtunis•2h ago
All I really need right now is an app that would restrict certain apps usage to certain time slots.

I already cut my social apps usage to 2 hours per day, which is a huge success.

Now I want to stop myself from diving head-first into Instagram the moment I wake up. If only I can make these apps accessible only from 10am to 02pm.

Any suggestions?

(I tried parental control but it requires having only one logged-in account which I can't fulfill.)

sphars•2h ago
There may be DNS-based solutions. I use NextDNS to block reddit except for 7-10pm using the recreation time settings.
dominis•1h ago
I had the same problem, browser extensions weren't enough, and I wanted something system-wide. So I built Sinkzone [1], a DNS tool that blocks everything unless allowlisted. It’s open-source and works across OSs. Thought it might be helpful if you're looking beyond NextDNS.

[1] https://github.com/berbyte/sinkzone

ahmedfromtunis•56m ago
It sadly doesn't work.

I tried blocking Facebook on my phone using both the parental control option AND adding `facebook.com` to the deny list.

Somehow, the app is still chugging along totally unbothered.

tinuviel•2h ago

> when i saw my screen time being about 11hrs with ~95 phone pickups per day, i realized how bad it got.

I get the problem you’re describing, but are you sure about these numbers? Screen Time has been broken since iOS 18 and reports really large (and totally random) numbers. I gave up using Screen Time after repeatedly seeing that an app that I open everyday for two minutes (I know this) shows up as 45 minutes, one hour and so on.

It’s good to pay attention to one’s use of a smart device, but I’d recommend not relying on iOS Screen Time reports.

About this app though, I have stopped buying apps that don’t give long enough trials. So this one is not for me. I’d suggest making the trial seven days (at the minimum).

joloooo•2h ago
I've always been curious about creating a collective pool of money - from subscriptions for something like this. The user only pays if they break their focus. Could even redistribute the pot to those who last at the end of the month/week / whatever.
wavemode•1h ago
> We don't have a start button because your life has already started, and you're wasting it.

Gave me a very good laugh.

> I made the hardest focus app

This is baby tutorial level.

Look into iOS device management.

Let users let you manage the device.

If they don't put it back in their pocket, wipe the device.

Yeah.

They can restore from iCloud, but come on.

You talk big talk, be big stick.
