Je suis pour l’instant, complètement bloqué car j’ai oublier mon mot de passe. Donc si quelqu’un peu m’indiquer comment récupérer mon mot de passe.👍👍 **Developer response:** Thank you for sharing your thoughts. If you encounter any issues, please contact us at Support@iappcreation.com. Thank you! 😊 ### 5/5 — Jmelgar *2025-04-26* This is the best app I have ever used to protect my passwords. I recommend using this very highly. **Developer response:** Thank you so much for your encouraging star ratings! 💖 💖 💖 ### 5/5 — Cat *2025-02-15, version 3.1.0* Love this app. Try it you’ll love it. ### 3/5 — Search Function?: NoteLock *2025-02-08* Very good App. I use this App a lot However, there should be a search function in that App. In absence of this, I am wasting my time searching for a particular word which I saved it long time back. **Developer response:** Thank you for your comment and feedback! 🙏 If you encounter any issues, please contact us at Support@iappcreation.com Thank you! 😊 ### 5/5 — Note Lock Wonder *2025-01-30* I love this app! Used this for my passwords notes so I won't forget! **Developer response:** Thank you! 💖 So happy you love our app! ### 1/5 — Doesn’t work correctly *2022-09-17* I unlocked all the options and they don’t work on my iPad Pro. I’m waiting for an answer from them now… ### 5/5 — Nice *2022-04-26* Great app I have used for years, very dependable, quick and easy to use. unfortunately I forgot my password combo and I can’t get in anymore :( there’s no way to bypass the unlock if you’ve forgotten the combo so it’s stuck now. ### 1/5 — I Have To Pay Again?? *2021-09-21* I purchased this app years ago, but now that they have a subscription service and changed the price, I’m not allowed to use the app anymore? I have to pay again to use an app I already purchased or lose the ability to keep using an app I have years of content in? ### 1/5 — Sigh *2021-07-02, version 3.0.5* Bought this years ago. Loved it. Kept loads of stories on it. I’m talking hundreds. Not exaggerating. It stopped updating, couldn’t open it, lost all of the stories. Fast forward to now July/1/2021, it updates. Now has a subscription, so even though I bought it before, all of my stories are still gone and I don’t have the full version anymore. Given that I was disappointed more than once and now I’m not sure I’d trust them with my notes, I’ll probably leave the app on to mourn the story graveyard but that’s it. Beware. ### 3/5 — Finally updated 6-30-21 *2021-07-01, version 2.0.2* This app has finally been updated by Apple. For all those who got locked out after iOS update. Get your info and save it. Make a copy. Hope it never happens again. Iapcreation just created a new version to work with current iOS but for everyone who was in earlier version there was no warning to upgrade or back up. It just stopped working. ## Frequently asked questions about Note Lock ~ Keep your secret ### What does Note Lock do?
