However, i did run into a bug where I am not able to modify the limits once set. The app asks me to input a reason but the button to proceed never gets enabled even after entering the reason **Developer response:** Thank you for the valuable feedback and I am glad that Precursor is useful to you! The bug you described might just be the need to hit a character limit for the reason. In general on normal limits mode the journal entry requires about 1 sentence for the reason, while on hard limits mode it requires about 2-3 sentences. If that doesn't solve the issue please reach out to support@precursorlabs.info with a screenshot so I can investigate further! Again, thanks a ton for the support! ### 4/5 — Add minute variation please *2026-09-12* Works well but would be nice if instead of screentime minutes being allotted in 5’s you could set them to more specific numbers like 8 or 22 **Developer response:** Hi, thank you so much for the feedback! The minute level granularity is definitely something I am always looking at implementing. While technically possible, the app would be way more prone to misfires and block users out of their apps prematurely. For now the 5 minute increments is the sweet spot I was able to find where Apple's screentime framework (which underlies Precursor) works reliably. Despite the limitation, I will continue to look for solutions because I agree, more fine tuned control would be nice to have! ### 5/5 — I kicked my habit in two weeks!!! *2026-10-29* This is the first app I have ever WANTED to write a review for. I had a hopeless TikTok doomscrolling addiction. I simply could not stop endlessly depressing myself with hours and hours of bad news and various forms of brain rot. I downloaded this and set it to 10 minutes per hour. Idk what the science is, but not only had this stymied my screen time, my addiction is almost non existent now!!! I used to instinctively grab my phone and swipe to tiktok like a chain smoker grabs cigarettes from his two packs a day. Now there are days when I FORGET to look at tiktok!!! Now I only use it when it’s meant to be used: when I’m waiting for something with absolutely nothing to do. Waiting for my pizza rolls to heat up. Waiting for the subway. Waiting in line at the bank. I feel so much better!!!! Thank you Precursor!!! 😭🙏🏻 ### 5/5 — I’ve been waiting for this *2026-10-04* Like everyone else I’ve struggled with scrolling endlessly on social media and news. Being able to set HOURLY limits is what I needed. 5 minutes every hour on all social media/ news scratches the itch till I can make it once a day. All the best to the dev and users of this app. edit: Can we add an inverse time window? So instead of setting hours to run the schedule (8-5) we set a limit where we set free time for certain hours or windows (noon for an hours five minutes) or within an evening window (6-8 5 minute intervals) Creating app groups or the ability to duplicate existing schedules also makes it easier to further customize time. Also any way to automatically toggle color filters so the screen goes black and white when five minute is over? Further reinforcing limitations? Big thanks from a lifetime subscriber! **Developer response:** I am so glad Precursor has helped you better manage your screen time habits. Truly that is my goal with this app, to just help people take back their time! Your support and kind words mean a lot! ### 5/5 — Bien *2026-09-08* Buena app y excelente uso. **Developer response:** Muchas Gracias! ### 5/5 — Such a game changer *2026-08-19* This app has been super helpful at navigating screen time limits, I love how aesthetic & cute it is, how positive the idea is & am so thankful I caught it in time for the free lifetime trial ! My new favorite time limit app!! Totally recommend !!!!!!! **Developer response:** Thank you so much for taking the time to write a review. I originally developed Precursor out of personal need and I am just so grateful that others like yourself are able to benefit from this unique approach to screen time limits! I also appreciate you noticing the subtle design choices, I think user experience is just as important as the function of the app! If you ever have feedback or feature requests please feel free to share them via the Precursor forum, available in the in app settings menu! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
