Uninstall ### 1/5 — Jot *2024-01-11* Mi hanno chiesto di pagare 0.99€ x farmi vedere le formule mai viste le formule anche dopo aver pagato ### 1/5 — PUBS !!!!!!!!!!! *2023-12-18* Application super tout est calculé directement mais les PUBS c’est juste pas possible, réellement on passe plus de temps à regarder les pubs qu’être sur l’application elle même. Dès qu’on modifie une longueur pour voir les modifications des angles hop une pub, pub et re pub. Appli supprimé j’ai même pas fini de voir ce que je voulais, je fais entrer une pub ensuite après avoir passé la pub je modifie une valeur même pas le temps de faire entrer PUB!! Alors que la dernière date de moins de 10sec. Il faut arrêter au bout d’un moment. C’est juste une appli qui utilise des formules pour faire un simple calcule même une appli calculatrice a pas de pub NE télécharger PAS , vous aller perdre votre temps aller sur internet prendre les formules avec une feuille, un crayon et une calculatrice faites le vous même ### 3/5 — ? *2023-02-06* Metric version available? ### 1/5 — Desesperante su publicidad *2022-11-16* Publicidad intrusiva y constantes cortes para que descargues la versión de pago ### 1/5 — Que Basura *2022-11-08* Hoy por la tarde pague el “VIP” para que me enseñara las fórmulas y al momento de pagar no me dejaba ver las fórmulas y me pedía volver a pagar, vaya basura de aplicación. QUIERO UN REMBOLSO ### 1/5 — Not good *2022-05-01, version 3.5.1* Inputting parameters for the very first calculation, a pop-up obstructs proceedings. Going into 'Settings' to see what can be customised, the same pop-up appears again, thus preventing any changes. Exiting Settings to have another go, the pop-up appears yet again. I can't be bothered with this kind of premature persuasion to buy the full version. Goodbye and good riddance. ### 1/5 — Finger weg *2022-04-19* Für Werbung bezahlt, trotzdem wird man ständig genötigt, auch noch für die Formeln zu bezahlen, das nervt. ### 1/5 — No fractions or decimal points? *2022-04-16, version 3.5.1* Really what simple math is this? ### 2/5 — Dommages PUB même après paiement de l’appli *2022-03-10* C’est vraiment dommage que une fois que nous avons payer l’application on a toujours des PUB ## Frequently asked questions about Triangle & Angle calculator ### What does the Triangle & Angle calculator app do?
